| 1 | High-altitude salt lake elevation changes and glacial ablation in Central Tibet, 2000-2010显示文摘This research quantifies lake level variations in the Siling Co, Co'e and Bangor Co salt lakes in Central Tibet from 1976 to 2010, and most notably for the 2000-2010 periods. In particular, the effects of different water replenishment modes on the lakes have been analyzed. Here we have provided new evidences for climate warming and accelerated glacial ablation on the Central Tibetan Plateau from 2000 to 2010. Based on fieldwork involving Differential Global Positioning System (DGPS) surveying and Remote Sensing (RS) interpretations of the lake area, we have drawn the following conclusions. (1) From 1976 to 2010, the process of lake level variation in Siling Co can be divided into two stages. From 1976 to 2000, the lake level rose 4.3 m in a steady fashion (from 4530 to 4534.3 m); the rise rate was 0.18 m/a. From 2000 to 2010, the lake level rapidly rose 8.2 m (from 4534.3 to 4542.5 m), with a dramatically higher rise rate of 0.82 m/a. Compared with the rapidly increasing lake level of Siling Co from 2000 to 2010, the fluctuations observed at Co'e and Bangor Co were smooth and inconspicuous. (2) From 1976 to 2009, the lake area of Siling Co experienced a steady-rapid-steady expansion pattern. The lake area of Siling Co increased 656.64 km2 in the 34 years to 2010, a proportional growth of 39.4%. This was particularly significant in the 2000-2010 period, when the lake area of Siling Co increased by 549.77 km2, a proportional growth of 30.6%. (3) According to correlation analysis, the rise in regional temperatures, which has led to the ablation of glaciers, is the main reason for the rapid rise in Siling Co lake levels in the 10 years to 2010. During this period, Siling Co rose approximately 8 m as the direct result of glacial melting. An increase in precipitation in the Siling Co catchment area is the secondary factor. This contrasts with Bangor Co, where the dominant factor in lake level change is the long-term increase in precipitation; here, the increasing temperature is the secondary factor. | MENG Kai SHI XuHua WANG Erchie LIU Feng | 2012 | Chinese Science Bulletin2012，57，5： | 17 |
| 2 | Estimation of the inter-frequency clock bias for the satellites of PRN25 and PRN01显示文摘We present two efficient approaches,namely the epoch-differenced(ED) and satellite-and epoch-differenced(SDED) approaches,for the estimation of IFCBs of the two Block IIF satellites.For the analysis,data from 18 stations from the IGS network spanning 96 d is processed.Results show that the IFCBs of PRN25 and PRN01 exhibit periodical signal of one orbit revolution with a magnitude up to 18 cm.The periodical variation of the IFCBs is modeled by a sinusoidal function of the included angle between the sun,earth and the satellite.The presented model enables a consistent use of L1/L2 clock products in L1/L5-based positioning.The algorithm is incorporated into the MGPSS software at SHAO(Shanghai Astronomical Observatory,Chinese Academy of Sciences) and is used to monitor the IFCB variation in near real-time. | LI HaoJun ZHOU XuHua WU Bin WANG JieXian | 2012 | Science China(Physics,Mechanics & Astronomy)2012，55，11： | 9 |

| 4 | An improved form of smoothed particle hydrodynamics method for crack propagation simulation applied in rock mechanics显示文摘The simulation of crack propagation processes in rock engineering has been not only a research hot spot among scholars but also a challenge.Based on this background,a new numerical method named improved kernel of smoothed particle hydrodynamics(IKSPH)has been put forward.By improving the kernel function in the traditional smoothed particle hydrodynamics(SPH)method,the brittle fracture characteristics of the base particles are realized.The particle domain searching method(PDSM)has also been put forward to generate the arbitrary complex fissure networks.Three numerical examples are analyzed to validate the efficiency of IKSPH and PDSM,which can correctly reveal the morphology of wing crack and the laws of crack coalescence compared with previous experimental and numerical studies.Finally,a rock slope model with complex joints is numerically simulated and the progressive failure processes are exhibited,which indicates that the IKSPH method can be well applied to rock mechanics engineering.The research results showed that IKSPH method reduces the programming difficulties and avoids the traditional grid distortion,which can provide some references for the application of IKSPH to rock mechanics engineering and the understanding of rock fracture mechanisms. | Shuyang Yu Xuhua Ren Jixun Zhang Haijun Wang Zhaohua Sun | 2021 | International Journal of Mining Science and Technology2021，31，3： | 6 |
| 5 | The expression profile of genes in rice roots under low phosphorus stress显示文摘Phosphorus (P) is one of the most essential macronutrients required for plant growth. Although it is abundant in soil, P is often the limiting nutrient for crop yield potential because of the low concentration of soluble P that plants can absorb directly. The gene expression profile was investigated in rice roots at 6, 24 and 72 h under low P stress and compared with a control (normal P) profile, using a DNA chip of 60000 oligos (70 mer) that represented all putative genes of the rice genome. A total of 795 differentially expressed genes were identified in response to phosphate (Pi) starvation in at least one of the treatments. Based on the analysis, we found that: (i) The genes coding for the Pi transporter, acid phosphatase and RNase were up-regulated in rice roots; (ii) the genes involved in glycolysis were first up-regulated and then down-regulated; (iii) several genes involved in N metabolism and lipid metabolism changed their expression patterns; (iv) some genes involved in cell senescence and DNA or protein degradation were up-regulated; and (v) some transmembrane transporter genes were up-regulated. The results may provide useful information in the molecular process associated with Pi deficiency and thus facilitate research in improving Pi utilization in crop species. | LI LiHua, QIU XuHua, LI XiangHua, WANG ShiPing & LIAN XingMing National Key Laboratory of Crop Genetic Improvement, National Center of Plant Gene Research (Wuhan), Huazhong Agricultural University, Wuhan 430070, China | 2009 | Science China(Life Sciences)2009，52，11： | 5 |
| 6 | Fracture of two three-dimensional parallel internal cracks in brittle solid under ultrasonic fracturing显示文摘Similar to hydraulic fracturing(HF), the coalescence and fracture of cracks are induced within a rock under the action of an ultrasonic field, known as ultrasonic fracturing(UF). Investigating UF is important in both hard rock drilling and oil and gas recovery. A three-dimensional internal laser-engraved crack(3D-ILC) method was introduced to prefabricate two parallel internal cracks within the samples without any damage to the surface. The samples were subjected to UF. The mechanism of UF was elucidated by analyzing the characteristics of fracture surfaces. The crack propagation path under different ultrasonic parameters was obtained by numerical simulation based on the Paris fatigue model and compared to the experimental results of UF. The results show that the 3D-ILC method is a powerful tool for UF research.Under the action of an ultrasonic field, the fracture surface shows the characteristics of beach marks and contains powder locally, indicating that the UF mechanism includes high-cycle fatigue fracture, shear and friction, and temperature load. The two internal cracks become close under UF. The numerical result obtained by the Paris fatigue model also shows the attraction of the two cracks, consistent with the test results. The 3D-ILC method provides a new tool for the experimental study of UF. Compared to the conventional numerical methods based on the analysis of stress-strain and plastic zone, numerical simulation can be a good alternative method to obtain the crack path under UF. | Haijun Wang Hanzhang Li Lei Tang Xuhua Ren Qingxiang Meng Chun Zhu | 2022 | Journal of Rock Mechanics and Geotechnical Engineering2022，14，3： | 4 |
| 7 | GNSS clock corrections densification at SHAO:from 5 min to 30 s显示文摘High frequency multi-GNSS zero-difference applications like Precise Orbit Determination(POD)for Low Earth Orbiters(LEO)and high frequency kinematic positioning require corresponding high-rate GNSS clock corrections.The determination of the GNSS clocks in the orbit determination process is time consuming,especially in the combined GPS/GLONASS processing.At present,a large number of IGS Analysis Centers(AC)provide clock corrections in 5-min sampling and only a few ACs provide clocks in 30-s sampling for both GPS and GLONASS.In this paper,an efficient epoch-difference GNSS clock determination algorithm is adopted based on the algorithm used by the Center for Orbit Determination in Europe(CODE).The clock determination procedure of the GNSS Analysis Center at Shanghai Astronomical Observatory(SHAO)and the algorithm is described in detail.It is shown that the approach greatly speeds up the processing,and the densified 30-s clocks have the same quality as the 5-min clocks estimated based on a zero-difference solution.Comparing the densified 30-s GNSS clocks provided by SHAO with that of IGS and its ACs,results show that our 30-s GNSS clocks are of the same quality as that of IGS.Allan deviation also gives the same conclusion.Further validation of the SHAO 30-s clock product is performed in kinematic PPP and LEO POD.Results indicate that the positions have the same accuracy when using SHAO 30-s GNSS clocks or IGS(and its AC)finals.The robustness of the algorithm and processing approach ensure its extension to provide clocks in 5-s or even higher frequencies.The implementation of the new approach is simple and it could be delivered as a black-box to the current scientific software packages. | CHEN JunPing ZHANG YiZe ZHOU XuHua PEI Xiao WANG JieXian WU Bin | 2014 | Science China(Physics,Mechanics & Astronomy)2014，57，1： | 4 |
| 8 | Analyses of factors forming offshore SST anomaly (O-SSTA) in China seas显示文摘Based on the observations, the location and the strength of warm(cold) anomaly of SST in surnmer are conrolled mainly by the subtropical highs of atmosphere (typhoon track) on the off shore of the China seas. It may be considered for the physical causes that the factors forming O-SSTA include the dynamic respome of upper layer ocean on tbe strong atmospheric forcing and the shallow sea effects. The former consists of the entrainment, the detrainment, the Ekman pumping and the convergence of surface warm watet; the later the tidal mixing and higher absorptivity. The parameterized expressions and the significance estimations of each factor are shown. The differences of both forming mechanisms and forming time-scales between the warm anomaly and the cold one are also indicated with different forcing systems. | Wang Sizhen, Li Xuhua, Qi Jianhua and Su Yusong (Ocean University of Qingdao, Qingdao 266003, China) | 1998 | Acta Oceanologica Sinica1998，17，4： | 4 |

| 12 | Transcriptomic analysis of rice responses to low phosphorus stress显示文摘Phosphorus is one of the essential macronutrients required for plant growth and development. The plants increase the absorption of phosphorus through an expansion of the root system in the soil when they are in low-phosphorus conditions. At the same time, the changes in biochemical metabolic pathways and the increase of secretion of phosphatase and organic acids activate the insoluble phosphate fixed in the soil. The expression profile in response to low phosphorus was investigated for rice at 6, 24 and 72 h after low-phosphorus stress compared with normal phosphorus conditions as a control with DNA chip. A total of 1207 differen- tially expressed genes were found in our study; 795 and 450 genes exhibited alterations in their RNA expression in response to inorganic phosphate (Pi) starvation in at least one of the three time points in roots and shoots. Thirty-eight genes overlapped in shoots and roots. The functional classification of these genes indicated their involvement in various metabolic pathways, ion transport, signal transduction, transcriptional regulation, and other processes related to growth and development. A large number of transposable elements changed the expression in rice after low-phosphorus stress. The results may provide useful information about molecular processes associated with Pi deficiency and facilitate the identification of key molecular determinants for improving Pi use by crop species. | LI LiHua QIU XuHua LI XiangHua WANG ShiPing ZHANG QiFa LIAN XingMing | 2010 | Chinese Science Bulletin2010，55，3： | 2 |

| 15 | Fracturing behavior of brittle solids containing 3D internal crack of different depths under ultrasonic fracturing显示文摘Ultrasonic fracturing(UF)can be used to form crack networks for oil or gas in the mining industry and hard rock excavation.In this paper,the three-dimensional internal laser-engraved crack method(3DILC)is introduced to make penny-shaped internal crack within the samples without any damage to the surfaces.Physical experiments were performed on the transparent samples with internal cracks at different depths.The macro-and micro-fracture fractography characteristics were focused on and analyzed in details.Based on fractography,the mechanisms of the UF were revealed.The propagation paths of cracks of different depths were simulated based on the Paris fatigue model and compared with experimental results.The results show that the 3D-ILC method is a powerful tool for the experimental research on the internal crack propagation in the UF.Under the action of ultrasonic field,fractography shows the characteristics of beach marks,lance-like pattern,rime-like pattern and glass powder.It can be judged that the mechanisms of UF include high cycle fatigue fracture,shear fracture,and friction.The results of the numerical simulation using the Paris fatigue model are consistent with the experimental results. | Haijun Wang Hanzhang Li Lei Tang Jianchun Li Xuhua Ren | 2022 | International Journal of Mining Science and Technology2022，32，6： | 1 |
| 16 | A numerical forecasting model of offshore-SST anomaly显示文摘An SST model which is good at predicting offshore-SST anomaly (O-SSTA) has been developed. It is composed of three parts: equations of dynamics, equations of model’s physics and equations of affecting factors of O-SSTA. Initial field of SST is prepared for a case of O-SSTA on last decade of July 1994, in which there are a center of warm anomaly in the Huanghai Sea and a center of cold anomaly in the East China Sea to be developing simultaneously. Using the Observed atmospheric forcing, the (decade) experiment forecast is made. Forecasting accuracy of warm (cold) anomaly is 32/44 (29/33 )’ the ensemble accuracy reaches R = 91% and AMD = 0. 67 t. The chief affecting factors of O-SSTA for this case are shown, for warm anomaly: (1 ) afar radiation (weight is 64 % ), (2) the convergence of warm water (9% ), (3 ) shallow-water effects; and for cold anomaly: (l) pumping of typhoon (44 % ), (2) entrainment of storm (24 % ), (3) latent heat (19 % ), respectively. It is identified that the formation of warm (cold) anomaly is a slower (faster) process. | Wang Sizhen Li Xuhua Qi Jianhua and Su Yusong (1.

| 20 | Ultra-thin CoAl layered double hydroxide nanosheets for the construction of highly sensitive and selective QCM humidity sensor显示文摘To achieve real-time monitoring of humidity in various applications,we prepared facile and ultra-thin CoAl layered double hydroxide(CoAl LDH)nanosheets to engineer quartz crystal microbalances(QCM).The characteristics of CoAl LDH were investigated by transmission electron microscopy(TEM),X-ray diffraction(XRD),X-ray photoelectric spectroscopy(XPS),Brunauer–Emmett–Telle(BET),atomic force microscopy(AFM)and zeta potential.Due to their large specific surface area and abundant hydroxyl groups,CoAl LDH nanosheets exhibit good humidity sensing performance.In a range of 11.3%and 97.6%relative humidity(RH),the sensor behaved an ultrahigh sensitivity(127.8 Hz/%RH),fast response(9.1 s)and recovery time(3.1 s),low hysteresis(3.1%RH),good linearity(R^(2)=0.9993),stability and selectivity.Besides,the sensor can recover the initial response frequency after being wetted by deionized water,revealing superior self-recovery ability under high humidity.Based on in-situ Fourier transform infrared spectroscopy(FT-IR),the adsorption mechanism of CoAl LDH toward water molecules was explored.The QCM sensor can distinguish different respiratory states of people and wetting degree of fingers,as well as monitor the humidity in vegetable packaging,suggesting excellent properties and a promising application in humidity sensing. | Yongheng Zhu Xuhua Dong Jinsheng Cheng Lumin Wang Cheng Zhao Yonghui Deng Siqi Xie Yingjie Pan Yong Zhao Gengzhi Sun Tianjun Ni | 2023 | Chinese Chemical Letters2023，34，8： | 1 |
