| 2 | Preparation and characterization of Eu^(3+)-doped CaCO_3 phosphor by microwave synthesis显示文摘A Eu3+-doped CaCO3 phosphor with red emission was prepared by microwave synthesis. The scanning electron microscopy (SEM) image and laser particle size analysis show that the CaCO3:Eu3+ particles are needle-like in the length range of 5.0-10.0 μm. The results of X-ray diffraction (XRD) analysis, Fourier transform infrared spectroscopy (FT-IR), and Raman spectroscopy indicate that pure aragonite CaCO3:Eu3+ is prepared using microwave irradiation and the Eu3+ ion as a luminescence center inhabits the site of Ca2+. The photoluminescence excitation (PLE) spectrum shows that the strong broad band at around 270 nm and weak sharp lines in 300-550 nm are assigned to the charge transfer band of Eu3+-O2- and intra-configurational 4f-4f transitions of Eu3+, respectively. The photoluminescence (PL) spectrum implies that the red luminescence can be attributed to the transitions from the 5D0 excited level to the 7FJ (J = 0, 1, 2, 3, 4) levels of Eu3+ ions with the mainly electric dipole transition 5D0 → 7F2 (614 and 620 nm), and the Eu3+ ions prefer to occupy the low symmetric site in the crystal lattice. | KANG Ming LIU Jun YIN Guangfu SUN Rong | 2009 | Rare Metals2009,28,5: | 13 |

| 4 | Q-switched and mode-locked Er-doped fiber laser using PtSe2 as a saturable absorber显示文摘We report a passively Q-switched and mode-locked erbium-doped fiber laser(EDFL) based on PtSe_2, a new two-dimensional material, as a saturable absorber(SA). Self-started Q-switching at 1560 nm in the EDFL was achieved at a threshold pump power of 65 mW, and at the maximum pump power of 450 m W, the maximum single Q-switched pulse energy is 143.2 n J. Due to the polarization-dependent characteristics of the PtSe_2-based SA, the laser can be switched from the Q-switched state to the mode-locked state by adjusting the polarization state. A mode-locked pulse train with a repetition rate of 23.3 MHz and a pulse width of 1.02 ps can be generated when the pump power increases to about 80 m W, and the stable mode-locked state is maintained until the pump power reaches its maximum 450 m W. The maximum single mode-locked pulse energy is0.53 nJ. This is the first time to our knowledge that successful generation of stable Q-switched and mode-locked pulses in an Er-doped fiber laser has been obtained by using PtSe_2 as a saturable absorber. | KANG ZHANG MING FENG YANGYANG REN FANG LIu XINGSHUO CHEN JIE YANG XIAO-QING VAN FENG SONG JIANGUO TIAN | 2018 | Photonics Research2018,6,9: | 10 |

| 7 | Effects of climate change on phenology and primary productivity in the desert steppe of Inner Mongolia显示文摘Variations in temperature and precipitation affect local ecosystems. Considerable spatial and temporal heterogeneity exists in arid ecosystems such as desert steppes. In this study, we analyzed the spatiotemporal dynamics of climate and vegetation phenology in the desert steppe of Inner Mongolia, China using meteorological data(1961–2010) from 11 stations and phenology data(2004–2012) from 6 ecological observation stations. We also estimated the gross primary production for the period of 1982–2009 and found that the annual mean temperature increased at a rate of 0.47oC/decade during 1961–2010, with the last 10 years being consistently warmer than the 50 years as an average. The most significant warming occurred in winters. Annual precipitation slightly decreased during the 50-year period, with summer precipitation experiencing the highest drop in the last 10 years, and spring precipitation, a rise. Spatially, annual precipitation increased significantly in the northeastern and eastern central areas next to the typical steppe. From 2004 to 2012, vegetation green-up and senescence date advanced in the study area, shortening the growing season. Consequently, the primary productivity of the desert steppe decreased along the precipitation gradient from southeast to northwest. Temporally, productivity increased during the period of 1982–1999 and significantly decreased after 2000. Overall, the last decade witnessed the most dramatic climatic changes that were likely to negatively affect the desert steppe ecosystem. The decreased primary productivity, in particular, decreases ecosystem resilience and impairs the livelihood of local farmers and herdsmen. | Fang HAN Qing ZHANG Alexander BUYANTUEV Jian Ming NIU Peng Tao LIU Xing Hua LI Sarula KANG Jing ZHANG Chang Ming CHANG Yun Peng LI | 2015 | Journal of Arid Land2015,7,2: | 8 |

| 9 | Carbonaceous particles in the atmosphere and precipitation of the Nam Co region, central Tibet显示文摘A continuous air and precipitation sampling for carbonaceous particles was conducted in a field observatory beside Nam Co, Central Tibetan Plateau during July of 2006 through January of 2007. Organic carbon (OC) was the dominant composition of the carbonaceous particles both in the atmosphere (1660 ng/m 3 ) and precipitation (476 ng/g) in this area, while the average elemental carbon (BC) concentrations in the atmosphere and precipitation were only 82 ng/m 3 and 8 ng/g, respectively. Very high OC/BC ratio suggested local secondary organic carbon could be a dominant contribution to OC over the Nam Co region, while BC could be mainly originated from Southern Asia, as indicated by trajectory analysis and aerosol optical depth. Comparison between the BC concentrations measured in Lhasa, those at 'Nepal Climate Observatory at Pyramid (NCO-P)' site on the southern slope of the Himalayas, and Nam Co suggested BC in the Nam Co region reflected a background with weak anthropogenic disturbances and the emissions from Lhasa might have little impact on the atmospheric environment here, while the pollutants from the Indo-Gangetic Basin of Southern Asia could be transported to the Nam Co region by both the summer monsoon and the westerly. | Jing Ming Cunde Xiao Junying Sun Shichang Kang Paolo Bonasoni | 2010 | Journal of Environmental Sciences2010,22,11: | 7 |
| 10 | Genomic variation in the hybrids of white crucian carp and red crucian carp: evidence from ribosomal DNA显示文摘In this study, we conducted a cross of white crucian carp(♀)×red crucian carp(♂)(WR), and characterized the morphology, reproduction and genetics of the progeny. Different from parents, WR with the gray color showed the hybrid morphological traits of both parents. WR possessed normal gonads producing mature eggs or sperm, and exhibited high fertilization rate(90.2%) and high hatchery rate(80.5%), which contributed to produce and enlarge the population. WR with the same DNA content as parents was a diploid fish with 100 chromosomes(2n=100). Amplified ITS of 45 S r DNA, in WR the sequences consisting of 884 bp bases of the entire ITS-1 region, 5.8 S region, and entire ITS-2 region. The sequences showed high similarity between WR and its parents and leaned towards male inheritance. In WR, NTS of 5S r DNA consisted of three length types with total 654 bp bases. From sequence analysis of NTS, WR shared 94.2% and 95.1% similarities with their female and male parent, respectively. Sequence analysis of ITS and NTS revealed that there existed recombination and variation in the hybrid progeny, which was the genetic base for adaptation and speciation. In conclusion, we obtained WR from hybridization and it exhibited hybrid traits in morphology and variation in genetic composition showing essential difference with its parents. The obtainment of WR has important significance in fish genetic breeding. | WANG Jing XIAO Jun ZENG Ming XU Kang TAO Min ZHANG Chun DUAN Wei LIU WenBin LUO KaiKun LIU Yun LIU ShaoJun | 2015 | Science China(Life Sciences)2015,58,6: | 7 |
| 11 | Effect of Simulated Microgravity and its Associated Mechanism on Pulmonary Circulation in Rats显示文摘Objective To study the effect of Simulated Microgravity and its Associated Mechanism on Pulmonary Circulation in Rats. Methods Rat tail-suspension model was used to simulate the physiological effects of microgravity and changes in pulmonary blood vessel morphology, pulmonary arterial and venous blood pressure, pulmonary vascular resistance, pulmonary vasomotoricity, as well as the regulation of pulmonary circulation by cytokines produced and released by the lung of rats were measured. Results The walls of pulmonary blood vessels of rats were thickened, and the pulmonary artery was reconstructed with increased pulmonary vascular resistance. The pulmonary blood vessels of rats became more prone to dilation as contractions increased. Rat epithelial Adrenomedulin gene transcription and protein expression were upregulated. The level of basic fibroblast growth Factor of rat was also elevated. Conclusion Findings from the present study on rats revealed that the microgravity can affect pulmonary blood vessel structure, pulmonary arterial pressure, and pulmonary blood vessel self-regulation and cytokine production. | LI Tian Zhi YUAN Ming CHEN Zhen Hong GUO Ying Hua KANG Chun Yan WANG Jing Yu LI Zhi Li WANG De Sheng WANG Hui Juan YUAN Min LIU Chang Ting | 2013 | Biomedical and Environmental Sciences2013,26,2: | 6 |

| 15 | Mechanically reprogrammable Pancharatnam-Berry metasurface for microwaves显示文摘Metasurfaces have enabled the realization of several optical functionalities over an ultrathin platform,fostering the exciting field of flat optics.Traditional metasurfaces are achieved by arranging a layout of static meta-atoms to imprint a desired operation on the impinging wavefront,but their functionality cannot be altered.Reconfigurability and programmability of metasurfaces are the next important step to broaden their impact,adding customized on-demand functionality in which each meta-atom can be individually reprogrammed.We demonstrate a mechanical metasurface platform with controllable rotation at the meta-atom level,which can implement continuous Pancharatnam–Berry phase control of circularly polarized microwaves.As the proof-of-concept experiments,we demonstrate metalensing,focused vortex beam generation,and holographic imaging in the same metasurface template,exhibiting versatility and superior performance.Such dynamic control of electromagnetic waves using a single,low-cost metasurface paves an avenue towards practical applications,driving the field of reprogrammable intelligent metasurfaces for a variety of applications. | Quan Xu Xiaoqiang Su Xueqian Zhang Lijuan Dong Lifeng Liu Yunlong Shi Qiu Wang Ming Kang Andrea Alù Shuang Zhang Jiaguang Han Weili Zhang | 2022 | Advanced Photonics2022,4,1: | 5 |
| 16 | Effect of direct current pulse stimulating acupoints of JiaJi (T10-L3) and Ciliao (BL 32) with Han's Acupoint Nerve Stimulator on labour pain in women: a randomized controlled clinical study显示文摘OBJECTIVE: To assess the clinical effect and safety of direct current(DC) pulse produced by Han's Acupoint Nerve Stimulator in reduction(HANS) of labor pain.METHODS: Totally 120 participants were enrolled in this clinical trial, and were randomly divided into4 groups including: HANS group, patient controlled intravenous analgesia(PCIA) group, patient-controlled epidural analgesia(PCEA) group and control group. The HANS group was treated by stimulating the acupoints of Jia Ji(T10-L3) and Ciliao(BL 32)with DC pulse of 100 Hz and 15-30 m A produced by a portable battery-powered Han's Acupoint Nerve Stimulator for 30 min. The PCIA group was intravenously infused Ondansetron(8 mg) for 5 min,then tramadol injection(1.5 mg/kg) was slowly dripped by using Baxter APⅡ electronic pump with50 m L tramadol(0.70%) + ondansetron(8 mg),background infusion 2 m L/h, PCA dose of 2 m L,lockout interval of 10 min. In PCEA group, women received intrathecal injection ropivacaine(3 mg) in L2-3, and epidural catheter was connected to Baxter APⅡ electronic pump, with 100 m L Ropivacaine(0.1%) and Sufentanil(50 ug), background infusion5 m L, Patient controlled analgesia(PCA) dose of 5m L, lockout interval of 10 min. The control group was not received analgesia. The visual analogue scale(VAS), stage and manner of labor, Apgar score of newborn, neonatal weights, oxytocin dosage,postpartum hemorrhage and side effects were monitored in all groups.RESULTS: The vital signs were all stable in the four analgesic groups. After analgesia, there was statistical difference in VAS score between HANS group and control group, between PCEA group and the control group, between PCIA group and control group. The analgesic effect in the PCEA group was significantly better than that of other two groups.The second stage of labor in the PCEA group was longer than the other three groups, showing significant difference between them. The Apgar score of newborn 1min after birth in the PCIA group was slightly lower than that of the other two groups,showing significant difference between them. The neonatal weights between four groups were not significantly different. The rate of cesarean sectionin the control group was significantly higher than that of the labor analgesia group, there was statistically difference in four groups. The number of PCIA group that used oxytocin was lower than that of other three groups. There was no significant difference in postpartum hemorrhage between four groups. The side effects of the PCEA group were itching, uroschesis and neonatal asphyxia and PCIA group were nausea and vomiting and neonatal asphyxia. However, fewer side effects were observed in the HANS group.CONCLUSION: The DC pulse produced by HANS may be a non-pharmacological alternative to labor pain with fewer side effects. | Liu Ye Xu Mingjun Che Xiangming He Junqin Guo Dandan Zhao Guosheng Zhang Guogang Zhang Shuo Kang Kai Zhang Chunlei Wang Yinan Li Shan Zhang Qinglin Xu Li Zhang Ming Han Bin Jing Yumiao Zhang Ning | 2015 | Journal of Traditional Chinese Medicine2015,35,6: | 4 |

| 18 | Sand-fixing characteristics of Carex brunnescens and its application with straw checkerboard technique in restoration of degraded alpine meadows显示文摘Carex brunnescens(Pers.), a typical clonal species, is considered to be the only herb found to date that can develop on sand dunes in Maqu alpine region of northwestern China. However, the characteristics that C. brunnescens resists to harsh alpine environment have not been documented. In this study, we conducted a field investigation to determine the morphological, reproductive, and sand-fixing characteristics of C. brunnescens. Concomitantly, we transplanted the belowground rhizomes of C. brunnescens to sand dunes and compared the abilities to restore degraded alpine meadows among sand dunes that had no further treatment(SD+N), sand dunes that had straw checkerboard technique but no transplanted rhizomes of C. brunnescens(SD+SCT), and sand dunes that had both SCT and transplanted rhizomes of C. brunnescens(SD+SCT+P). We found that belowground vertical rhizomes and horizontal rhizomes(including branching rhizomes and main rhizomes) of C. brunnescens were highly developed and that population reproduction was dominated by horizontal rhizomes. C. brunnescens exhibited a significant sand-fixation effect under following conditions: population density was 145–156 ramets/m^2, vegetation cover was 31.2%–39.3%, total length of belowground rhizomes was 11,223 cm/m^2, total length of belowground first-order roots was 9161–10,524 cm/m^2, fresh weight of aboveground part was 198.5–212.6 g/m^2, and fresh weight of belowground part was 578.8–612.4 g/m^2. It should be particularly noted that SD+SCT+P treatment(sand dunes that had both straw checkerboard technique and transplanted rhizomes of C. brunnescens) was the best and SD+N(sand dunes that had no further treatment) was the worst in terms of following biotic indicators: total number of reproductive ramets, total number of belowground rhizomes, and fresh weight of aboveground and belowground parts of C. brunnescens, contents of soil organic carbon, available nitrogen, microbial biomass carbon, and microbial biomass nitrogen. It implies that applying SCT in sand dunes and transplanting belowground rhizomes to sand dunes with SCT could improve both soil fertility and growth of C. brunnescens. These results suggest that the SCT-promoted high reproductive abilities of belowground rhizomes of C. brunnescens can successfully facilitate the establishment of ramets and can thus be an effective strategy to restore degraded vegetation in Maqu alpine region of northwestern China. | KANG Jianjun ZHAO Ming TAN Yanrong ZHU li BING Danhui ZHANG Yangdong TONG Shengli | 2017 | Journal of Arid Land2017,9,5: | 4 |

| 20 | Theoretical and experimental analysis of continuous casting with soft-contacted mould显示文摘Coupling the quasi 3D numerical simulation of electromagnetic field and the experiments with some metals such as tin, aluminum, copper and steel, the electromagnetic characteristics of continuous casting with soft contacted mould, especially the influences of power frequency, the mould structure, and the inductor position, size and current on the electromagnetic force and pressure on the billet, were analyzed. The result shows that, in continuous casting with soft contacted mould, the electromagnetic pressure on the surface of billet increases with the rising of the power frequency as a logarithmically parabolic function and, with that of inductor current as a parabolic function. The design principle of the soft contacted mould is that 1) the mould structure should be ‘more segments and thin slits’; 2) the topside of inductor should be at the same location with the meniscus of molten metal; 3) the inductor should cover the initial solidifying shell of billet. | DENG Kang(邓康) REN Zhong ming(任忠鸣) JIANG Guo chang(蒋国昌) | 2000 | 中国有色金属学会会刊:英文版2000,10,3: | 4 |
