| 1 | Modeling study of regional severe hazes over mid-eastern China in January 2013 and its implications on pollution prevention and control显示文摘The Nested Air Quality Prediction Model System(NAQPMS)was used to investigate the temporal and spatial variations of PM2.5over tropospheric central eastern China in January 2013.The impact of regional transport and its implications on pollution prevention and control were also examined.Comparison between simulated and observed PM2.5showed NAQPMS was able to reproduce the evolution of PM2.5during heavy haze episodes.The results indicated that regional transport of PM2.5played an important role in regional haze episodes in the city cluster including Hebei,Beijing and Tianjin(HBT).The cross-city clusters transport outside HBT and transport among cities inside HBT contributed 20%–35%and 26%–35%of PM2.5as compared with local emission,in HBT respectively.To meet the Air Quality Standards for Grade II,90%,90%and65%of emissions would have to be cut down in Hebei,Tianjin and Beijing,if non-control strategy was taken in the surrounding city clusters of HBT.This implicated that control of emissions in one city cluster is not sufficient to reduce regional haze events,and joint efforts among city clusters are essential.Besides regional transports,two-way feedback between boundary-layer evolution and PM2.5also significantly contributed to the formation of heavy hazes,which contributed 30%of monthly average PM2.5concentration in HBT. | WANG ZiFa LI Jie WANG Zhe YANG WenYi TANG Xiao GE BaoZhu YAN PinZhong ZHU LiLi CHEN XueShun CHEN HuanSheng WAND Wei LI JianJun LIU Bing WANG XiaoYan WAND Wei ZHAO YiLin LU Ning SU DeBin | 2014 | Science China Earth Sciences2014,57,1: | 106 |

| 4 | Resveratrol Induces Apoptosis and Autophagy in T-cell Acute Lymphoblastic Leukemia Cells by Inhibiting Akt/mTOR and Activating p38-MAPK显示文摘Objective To explore the effects of resveratrol-induced apoptosis and autophagy in T-cell acute lymphoblastic leukemia(T-ALL) cells and potential molecular mechanisms. Methods The anti-proliferation effect of resveratrol-induced, apoptosis and autophagy on T-ALL cells were detected by using MTT test, immunofluorescence, electronic microscope, and flow cytometry, respectively. Western blotting was performed for detecting changes of apoptosis-associated proteins, cell cycle regulatory proteins and state of activation of Akt, mTOR, p70S6K, 4E-BP1, and p38-MAPK. Results Resveratrol inhibited the proliferation and induced apoptosis and autophagy in T-ALL cells in a dose and time-dependent manner. It also induced cell cycle arrest at G0/G1 phase via up regulating cyclin-dependent kinase(CDK) inhibitors p21 and p27 and down regulating cyclin A and cyclin D1. Western blotting revealed that resveratrol significantly decreased the expression of antiapoptotic proteins(Mcl-1 and Bcl-2) and increased the expression of proapoptotic proteins(Bax, Bim, and Bad), and induced cleaved-caspase-3 in a time-dependent manner. Significant increase in ratio of LC3-II/LC3-I and Beclin 1 was also detected. Furthermore, resveratrol induced significant dephosphorylation of Akt, mTOR, p70S6K, and 4E-BP1, but enhanced specific phosphorylation of p38-MAPK which could be blocked by SB203580. When autophagy was suppressed by 3-MA, apoptosis in T-ALL cells induced by resveratrol was enhanced.Conclusion Our findings have suggested that resveratrol induces cell cycle arrest,apoptosis,and autophagy in T-ALL cells through inhibiting Akt/mTOR/p70S6K/4E-BP1 and activating p38-MAPK signaling pathways.Autophagy might play a role as a self-defense mechanism in T-ALL cells treated by resveratrol.Therefore,the reasonable inhibition of autophagy in T-ALL cells may serve as a promising strategy for resveratrol induced apoptosis and can be used as adjuvant chemotherapy for T-ALL. | GE Jiao LIU Yan LI Qiang GUO Xia GU Ling MA Zhi Gui ZHU Yi Ping | 2013 | Biomedical and Environmental Sciences2013,26,11: | 38 |

| 6 | Circular RNA circ-LDLRAD3 as a biomarker in diagnosis of pancreatic cancer显示文摘AIM To analyze the diagnostic value of a circular RNA(circR NA), circ-LDLRAD3, in pancreatic cancer.METHODS Expression levels of circ-LDLRAD3 were tested in both cells and clinical samples; the latter included 30 paired pancreatic cancer tissues and adjacent non-tumorous tissues, 31 plasma samples from patients with pancreatic cancer, and 31 plasma samples from healthy volunteers. Real-time quantitative reverse transcriptionpolymerase chain reaction(q RT-PCR) was performed to measure expression levels of circ-LDLRAD3 in cells and clinical samples; then, the relationship between clinicopathological factors of patient samples and expression of circ-LDLRAD3 in pancreatic cancer was analyzed. The diagnostic value of circ-LDLRAD3 was verified by receiver operating characteristic(ROC) curve analysis.RESULTS Circ-LDLRAD3 was up-regulated in pancreatic cancer cell lines(P < 0.01), pancreatic cancer tissues(P < 0.01), and plasma samples from patients with pancreatic cancer(P < 0.01). High expression of circLDLRAD3 was significantly associated with venous invasion, lymphatic invasion, and metastasis. The area under the ROC curve of circ-LDLRAD3 alone or combination with CA19-9 was 0.67 and 0.87, respectively, with a sensitivity and specificity of 0.5738(alone) and 0.7049(alone), and 0.8033(combination) and 0.9355(combination), respectively.CONCLUSION These data suggest that circ-LDLRAD3 may be a biomarker in the diagnosis of pancreatic cancer. | Fan Yang Dong-Yan Liu Jin-Tao Guo Nan Ge Ping Zhu Xiang Liu Sheng Wang Guo-Xin Wang Si-Yu Sun | 2017 | World Journal of Gastroenterology2017,23,47: | 25 |
| 7 | Using Interrupted Time Series Design to Analyze Changes in Hand, Foot, and Mouth Disease Incidence during the Declining Incidence Periods of 2008-2010 in China显示文摘Objective To identify patterns of hand, foot and mouth disease (HFMD) incidence in China during declining incidence periods of 2008, 2009, and 2010. Methods Reported HFMD cases over a period of 25 months were extracted from the National Disease Reporting System (NDRS) and analyzed. An interrupted time series (ITS) technique was used to detect changes in HFMD incidence rates in terms of level and slope between declining incidence periods of the three years. Results Over 3.58 million HFMD cases younger than 5 years were reported to the NDRS between May 1, 2008, and May 31, 2011. Males comprised 63.4% of the cases. ITS analyses demonstrated a significant increase in incidence rate level (P<0.0001) when comparing the current period with the previous period. There were significant changes in declining slopes when comparing 2010 to 2009, and 2010 to 2008 (all P<0.005), but not 2009 to 2008. Conclusion Incremental changes in incidence rate level during the declining incidence periods of 2009 and 2010 can potentially be attributed to a few factors. The more steeply declining slope in 2010 compared with previous years could be ascribed to the implementation of more effective interventions and preventive strategies in 2010. Further investigation is required to examine this possibility. | YU Shi Cheng HAO Yuan Tao ZHANG Jing XIAO Ge Xin LIU Zhuang ZHU Qi MA Jia Qi WANG Yu | 2012 | Biomedical and Environmental Sciences2012,25,6: | 23 |

| 9 | Relationship between cytokines gene polymorphism and susceptibility to hepatitis B virus intrauterine infection显示文摘Background The influences of genomic background are confirmed in more diseases. Immunologic tolerance after intrauterine infection of hepatitis B virus is considered to occur in T cells. Cytokines work effectively in eliminating virus by immune system after hepatitis B virus infection. To explore the relationship between cytokines (tumor necrosis factor-α, interferon-γ, interleukin-4 and interleukin-10), which expressed abnormal quantity in the peripheral blood to intrauterine hepatitis B virus infectious children, gene single nucleotide polymorphism (SNP) and susceptibility to hepatitis B virus intrauterine infection. Methods This is a cross sectional study of molecular clinical epidemiology. The subjects in this study were selected from outpatients of hepatitis B vaccine follow-up special clinics of our hospital in the period. According to intrant criteria, the high risk children of hepatitis B virus (HBV) intrauterine infection were divided into immune failure group (group Ⅰ); and immune effective group (group Ⅱ) and non high risk children belonged to the control group. Four gene SNP sites of TNF-α -238, IFN-γ +874, IL-4 -590 and IL-10 -1082 were determined by real-time quantitative fluorescent polymerase chain reaction (PCR). Results The significant differences of TNF-α -238 A allele frequency were found between group Ⅰ and groupⅡ (χ2=6.797,P<0.05) and between groupⅠ and the control group (χ2=9.513,P<0.05). No evident differences of TNF-α -238 A were found between group Ⅱ and control group (χ2=0.047,P>0.05); the significant differences of IFN-γ +874 A allele frequency were found between groupⅠ and groupⅡ(χ2=7.238,P<0.05), and between groupⅠ and the control group (χ2=5.199,P<0.05). No evident differences were found between groupⅡ and the control group (χ2=0.602,P>0.05); the significant differences of IL-4 -590 C/T allele frequency were not found between groupⅠand group Ⅱ(χ2=0.632,P>0.05), also groupⅠ and the control group (χ2=0.584,P>0.05), and the groupⅡ and the control group (χ2=0.004,P>0.05)respectively; The significant differences of IL-10 -1082 G allele frequency were found between groupⅡ and groupⅠ (χ2=10.359,P<0.001), and between groupⅡ and the controls (χ2=35.418,P<0.001), but the significant differences were not found between groupⅠand the control group (χ2=1.759,P>0.05). Conclusions This study suggested the possibility that the TNF-α -238 A allele and IFN-γ +874 A allele were associated with HBV intrauterine infection. There was no evident relationship between IL-4 -590 C/T allele SNP and susceptibility to HBV intrauterine infection, but the IL-10 -1082 G allele was associated with preventive efficacy to HBV intrauterine infection. | ZHU Qi-rong GE Yan-ling GU Shao-qing YU Hui WANG Jian-she GU Xin-huan FEI Lin-e DONG Zuo-quan | 2005 | Chinese Medical Journal2005,,19: | 21 |

| 11 | Over-expression of Metastasis-associated in Colon Cancer-1 (MACC1) Associates with Better Prognosis of Gastric Cancer Patients显示文摘Objective: The aim of this study was to detect metastasis-associated in colon cancer-1 (MACC1) expression in Chinese gastric cancer and analyze the relationship between MACC1 expression and postoperative survival. Methods: The expression of MACC1 and c-MET protein in a sample of 128 gastric cancer tissues was detected by immunohistochemistry. A retrospective cohort study on the prognosis was carried out and data were collected from medical records. Results: The positive rate of MACC1 protein expression in gastric cancer was 47.66%, higher than that in adjacent noncancerous mucosa (P<0.001). MACC1 protein expression was not related to the clinicopathological variables involved. Kaplan-Meier analysis revealed that the survival of MACC1 positive group tended to be better than that of MACC1 negative group, particularly in patients with stage III carcinoma (P=0.032). Cox regression analysis revealed that MACC1 protein over-expression in gastric cancer tended to be a protective factor with hazard ratio of 0.621 (P=0.057). Immunohistochemical analysis showed that the positive rate of c-MET protein expression was much higher in cases with positive MACC1 expression in gastric cancer (P=0.002), but P53 expression was not associated with MACC1 expression. Conclusion: MACC1 over-expression implies better survival and may be an independent prognostic factor for gastric cancer in Chinese patients. | Shao-hua Ge Xiao-jiang Wu Xiao-hong Wang Xiao-fang Xing Lian-hai Zhang Yu-bing Zhu Hong Du Bin Dong Ying Hu Jia-fu Ji | 2011 | Chinese Journal of Cancer Research2011,23,2: | 19 |

| 14 | Effectiveness of 5-flurouracil-based neoadjuvant chemotherapy in locally-advanced gastric/gastroesophageal cancer:A meta-analysis显示文摘AIM:To investigate the effectiveness of 5-flurouracilbased neoadjuvant chemotherapy(NAC) for gastroesophageal and gastric cancer by meta-analysis.METHODS:MEDLINE and manual searches were performed to identify all published randomized controlled trials(RCTs) investigating the efficacy of the flurouracilbased NAC for gastroesophageal and gastric cancer,and RCTs of NAC for advanced gastroesophageal and gastric cancer vs no therapy before surgery.Studies that included patients with metastases at enrollment were excluded.Primary endpoint was the odds ratio(OR) for improving overall survival rate of patients with gastroesophageal and gastric cancer.Secondary endpoints were the OR of efficiency for down-staging tumor and increasing R0 resection in patients with gas-troesophageal and gastric cancer.Safety analyses were also performed.The OR was the principal measurement of effect,which was calculated as the treatment group(NAC plus surgery) vs control group(surgery alone) and was presented as a point estimate with 95% confidence intervals(CI).All calculations and statistical tests were performed using RevMan 5.1 software.RESULTS:Seven RCTs were included for the analysis.A total of 1249 patients with advanced gastroesophageal and gastric cancer enrolled in the seven trials were divided into treatment group(n = 620) and control group(n = 629).The quality scores of the RCTs were assessed according to the method of Jadad.The RCT quality scores ranged from 2 to 7(5-point scale),with a mean of 3.75.The median follow-up time in these studies was over 3 years.The meta-analysis showed that NAC improved the overall survival rate(OR 1.40,95%CI 1.11-1.76;P = 0.005),which was statistically significant.The 3-year progression-free survival rate was significantly higher in treatment group than in control group(37.7% vs 27.3%)(OR 1.62,95%CI 1.21-2.15;P = 0.001).The tumor down-stage rate was higher in treatment group than in control group(55.76% vs 41.38%)(OR 1.77,95%CI 1.27-2.49;P = 0.0009) and the R0 resection rate of the gastroesophageal and gastric cancer was higher in treatment group than in control group(75.11% vs 68.56%)(OR 1.38,95%CI 1.03-1.85;P = 0.03),with significant differences.No obvious safety concerns about mortality and complications were raised in these trials.There were no statistically significant differences in perioperative mortality(5.08% vs 4.86%)(OR 1.05,95%CI 0.57-1.94;P = 0.87 fixed-effect model) and in the complication rate between the two groups(13.25% vs 9.66%)(OR 1.40,95%CI 0.91-2.14;P = 0.12 fixed-effect model).Trials showed that patients from Western countries favored NAC compared with those from Asian countries(OR 1.40,95%CI 1.07-1.83).Monotherapy was inferior tomultiple chemotherapy(OR 1.40,95%CI 1.07-1.83).Intravenous administration of NAC was more advantageous than oral route(OR 1.41,95%CI 1.09-1.81).CONCLUSION:Flurouracil-based NAC can safely improve overall survival rate of patients with gastroesophageal/gastric cancer.Additionally,NAC can down the tumor stage and improve R0 resection. | Lei Ge Hai-Jiang Wang Dong Yin Cheng Lei Jin-Feng Zhu Xiao-Hui Cai Guo-Qing Zhang | 2012 | World Journal of Gastroenterology2012,18,48: | 19 |
| 15 | Co-infections with Babesia microti and Plasmodium parasites along the China-Myanmar border显示文摘Background:Babesiosis is an emerging health risk in several parts of the world.However,little is known about the prevalence of Babesia in malaria-endemic countries.The area along the China-Myanmar border in Yunnan is a main endemic area of malaria in P.R.China,however,human infection with Babesia microti(B.microti)is not recognized in this region,and its profile of co-infection is not yet clear.Methods:To understand its profile of co-infections with B.microti,our investigation was undertaken in the malaria-endemic area along the China-Myanmar border in Yunnan between April 2012 and June 2013.Four parasite species,including B.microti,Plasmodium falciparum(P.falciparum),P.vivax,and P.malariae,were identified among 449 suspected febrile persons detected by nested polymerase chain reaction(PCR)assay based on small subunit ribosomal ribonucleic acid(RNA)genes of B.microti and Plasmodium spp.Results:Of all the collected samples from febrile patients,mono-infection with B.microti,P.vivax,P.falciparum,and P.malariae accounted for 1.8%(8/449),9.8%(44/449),2.9%(13/449),and 0.2%(1/449),respectively.The rate of mixed infections of B.microti with P.falciparum or P.vivax are both 0.2%(1/449),and mixed infections of P.falciparum and P.vivax accounted for 1.1%(5/449).Conclusions:This report supports the hypothesis that babesiosis caused by B.microti is emerging along the China-Myanmar border in the Yunnan province,P.R.China,but it was ignored because of low parasitemia or mixed infection with Plasmodium spp.More sensitive and specific diagnosis methods are needed to find the rapid response mechanism of emergency for babesiosis and malaria co-prevalence areas. | Xia Zhou Sheng-Guo Li Shen-Bo Chen Jia-Zhi Wang Bin Xu He-Jun Zhou Hong-Xiang Zhu Ge Jun-Hu Chen Wei Hu | 2013 | Infectious Diseases of Poverty2013,2,1: | 18 |
| 16 | Effectiveness of Different Waist Circumference Cut-off Values in Predicting Metabolic Syndrome Prevalence and Risk Factors in Adults in China显示文摘Objective To study the effectiveness of waist circumference cut-off values in predicting the prevalence of metabolic syndrome(MetS) and risk factors in adults in China. Methods A cross-sectional survey was condcuted in 14 provinces(autonomous region, municipality) in China. A total of 47 325 adults aged ≥20 years were selected by multistage stratified sampling, and questionnaire survey and physical and clinical examination were conducted among them. MetS was defined according to the International Diabetes Federation(IDF) criteria and modified IDF criteria.Results The age-standardized prevalence of MetS was 24.2%(22.1% in men and 25.8% in women) and 19.5%(22.1% in men and 18.0% in women) according to the IDF criteria and modified IDF criteria respectively. The age-standardized prevalence of pre-MetS was 8.1%(8.6% in men and 7.8% in women) according to the modified IDF criteria. The prevalence of MetS was higher in urban residents than rural residents and in northern China residents than in southern China residents. The prevalence of central obesity was about 30% in both men and women according to the ethnicity-specific cut-off values of waist circumference for central obesity(90 cm for men and 85 cm for women). Multivariate regression analysis revealed no significant difference in risk factors between the two MetS definitions. Conclusion Using both the modified IDF criteria and ethnicity-specific cut-off values of waist circumference can provide more useful information about the prevalence of MetS in China. | ZHOU Hai Cheng LAI Ya Xin SHAN Zhong Yan JIA Wei Ping YANG Wen Ying LU Ju Ming WENG Jian Ping JI Li Nong LIU Jie TIAN Hao Ming JI Qiu He ZHU Da Long CHEN Li GUO Xiao Hui ZHAO Zhi Gang Li Qiang ZHOU Zhi Guang GE Jia Pu SHAN Guang Liang | 2014 | Biomedical and Environmental Sciences2014,27,5: | 17 |
| 17 | Neuroprotective effect of Notch pathway inhibitor DAPT against focal cerebral ischemia/reperfusion 3 hours before model establishment显示文摘As an inhibitor of the Notch signaling pathway, N-[N-(3,5-difluorohenacetyl)-l-alanyl]-S-phenylglycine tert-butyl ester(DAPT) may protect brain tissue from serious ischemic injury. This study aimed to explore neuroprotection by DAPT after cerebral ischemia/reperfusion(I/R) injury. DAPT was intraperitoneally injected 3 hours before the establishment of a focal cerebral I/R model in the right middle cerebral artery of obstructed mice. Longa scores were used to assess neurological changes of mice. Nissl staining and TdT-mediated dUTP-biotin nick-end labeling staining were used to examine neuronal damage and cell apoptosis in the right prefrontal cortex, while immunofluorescence staining was used to detect glial fibrillary acidic protein-and Notch1-positive cells. Protein expression levels of Hes1 and Hes5 were detected by western blot assay in the right prefrontal cortex. Our results demonstrated that DAPT significantly improved neurobehavioral scores and relieved neuronal morphological damage. DAPT decreased the number of glial fibrillary acidic protein-and Notch1-positive cells in the right prefrontal cortex, while also reducing the number of apoptotic cells and decreasing interleukin-6 and tumor necrosis factor-α contents, and simultaneously downregulating Hes1 and Hes5 protein expression. These findings verify that DAPT alleviates pathological lesions and strengthens the anti-inflammatory response after cerebral I/R injury. Thus, DAPT might be developed as an effective drug for the prevention of cerebral I/R injury. | Jun-Jie Wang Jun-De Zhu Xian-Hu Zhang Ting-Ting Long Guo Ge Yan Yu | 2019 | Neural Regeneration Research2019,14,3: | 17 |
| 18 | Cyclic Sequences, Events and Evolution of the Sino-Korean Plate, with a Discussion on the Evolution of Molar-tooth Carbonates, Phosphorites and Source Rocks显示文摘This paper gives an account of the research that the authors conducted on the cyclic sequences, events and evolutionary history from Proterozoic to Meso-Cenozoic in the Sino-Korean plate based on the principle of the Cosmos-Earth System. The authors divided this plate into 20 super-cyclic or super-mega-cyclic periods and more than 100 Oort periods. The research focused on important sea flooding events, uplift interruption events, tilting movement events, molar-tooth carbonate events, thermal events, polarity reversal events, karst events, volcanic explosion events and storm events, as well as types of resource areas and paleotectonic evolution. By means of the isochronous theory of the Cosmos-Earth System periodicity and based on long-excentricity and periodicity, the authors elaborately studied the paleogeographic evolution of the aulacogen of the Sino-Korean plate, the oolitic beach platform formation, the development of foreland basin and continental rift valley basin, and reconstructed the evolution of tectonic paleogeography and stratigraphic framework in the Sino-Korean plate in terms of evolutionary maps. Finally, the authors gave a profound discussion on the formation and development of molar-tooth carbonates, phosphorites and source rocks. | MENG Xianghua and GE MingInstitute of Sedimentary Basin, China University of Geosciences, Beijing 100083 E-mail: mengxh@cugb.edu.cn Liu Xinzhu and Zhu Xiling | 2003 | Acta Geologica Sinica(English Edition)2003,77,3: | 17 |
| 19 | The Clinical Outcomes of Three Surgical Managements on Primary Angle-closure Glaucoma显示文摘Purpose: To investigate the efficacy of trabeculectomy, phacotrabeculectomy and phaco-emulsification in the management of primary angle closure glaucoma (PACG). Methods: A prospective observational study was performed in 88 chronic PACG patients (97 eyes) who were divided into three groups following defined indications to receive different surgical interventions. The indications and clinical outcomes were evaluated. The mean follow-up was (17.7±4.9) months. Results: Success rate in trabeculectomy, phacotrabeculectomy and phacoemulsification group was 81.08%, 78.57‰ and 81.25‰, respectively. The anterior chamber depth was deeper and the angle was wider postoperatively vs. preoperatively both in phaco-trabeculectomy and phacoemulsification group. No obvious changes were seen in trabeculectomy group. The coefficient of outflow facility of aqueous humor (C values) significantly increased in three groups postoperatively (P < 0.01). No severe intra-operative complications were found and the incidence of postoperative complications was low. Five eyes sustained hypotony 3±1.87 months in trabeculectomy group and 1 eye happened malignant glaucoma in phacotrabeculectomy group. The visual acuity in patients with phacotrabeculectomy plus intraocular lens implantation and those only with phacoemulsification plus intraocular lens implantation were improved 78.57% and 93.74%, respectively. No significant improvement was found in trabeculectomy group (χ2 = 47.10, P < 0.001). Conclusion: Three surgical interventions were beneficial to manage PACG and with co-existing cataract. The indication choosing was suggested according to visual acuity, angle closure circumference, cataract, medication requirements and optic nerve damage. Phacotrabeculectomy was recommended for angle closed ≥180° circumference while phacoemulsification for angle closed < 180°. | Xiulan Zhang Leilei Teng Ang Li Shaolin Du Yunyun Zhu Jian Ge | 2007 | 眼科学报2007,23,2: | 16 |
| 20 | Double-stream-pouring technique for production of gradient materials by continuous casting显示文摘A novel method for producing gradient materials by continuous casting is introduced. By using many-stream-pouring technique, samples with gradient distribution of alloy composition along the cross section have been prepared. The main difference of this method from the conventional continuous casting is the pouring system equipped with two sets of tundishes for liquid metals of different alloy compositions. Special consideration is given to the promotion and control of the cross-sectional mass transport. The steady heat transfer and mass flow ensure a partial mixing of two metals and yield a continously varying composition distribution. By adjusting the processing parameters, composition profile with different shapes can be achieved. First experiments have been carried out in Al-Si system and Al-Cu system for three series of Al/AlSi, AlSi/Al and AlCu/Al. It is shown that the alloy composition, the microstructure and the mechanical property change smoothly from the centre to the surface of the samples. This simple and practical method is potential for mass prodution of 'structural gradient materials' and may offer a new way for alloy design. | Zhang Weiwen Zhu Cangshan Wei Xingzhao Meng Jilong Yuan Shugui Yu Ge | 1998 | Chinese Science Bulletin1998,43,11: | 16 |
