1Selective protection of glycinebetaine on extrinsic polypeptides of PS Ⅱ particles显示文摘PHOTOSYSTEM Ⅱ(PS Ⅱ) particles capable of O2 evolution contain D1, D2 transmembrane pro-teins, and three extrinsic polypeptides which are exposed to the outer aqueous phase with ap-parent molecular masses of 33, 23, 18 kD. The three proteins can be partially or totally re-moved by treating the PS Ⅱ membranes with high concentrations of salt or other methods,HOU Caixia, XU Chunhe, TANG Zhangcheng and SHEN YunkangShanghai Institute of Plant Physiology, Chinese Academy of Sciences, Shanghai 200032, China 1997Chinese Science Bulletin1997,42,20:4
2MICROMECHANICAL DAMAGE MODEL FOR ROCKS AND CONCRETES SUBJECTED TO COUPLED TENSILE AND SHEAR STRESSES显示文摘Based on the analysis of the deformation in an infinite isotropic elastic matrix with an embedded elliptic crack under far field coupled tensile and shear stresses, the energy release rate and a mixed fracture criterion are obtained using an energy balance approach. The additional compliance tensor induced by a single opening elliptic microcrack in a representative volume element is derived, and the effect of microcracks with random orientations is analyzed with the Taylor’s scheme by introducing an appropriate probability density function. A micromechanical damage model for rocks and concretes is obtained and is verified with experimental results.Zhongjun Ren Xianghe Peng Chunhe Yang 2008Acta Mechanica Solida Sinica2008,21,3:4
3Determination of the maximum allowable gas pressure for an underground gas storage salt cavern——A case study of Jintan,China显示文摘Increasing the allowable gas pressure of underground gas storage(UGS) is one of the most effective methods to increase its working gas capacity. In this context, hydraulic fracturing tests are implemented on the target formation for the UGS construction of Jintan salt caverns, China, in order to obtain the minimum principal in situ stress and the fracture breakdown pressure. Based on the test results, the maximum allowable gas pressure of the Jintan UGS salt cavern is calibrated. To determine the maximum allowable gas pressure, KING-1 and KING-2 caverns are used as examples. A three-dimensional(3D)geomechanical model is established based on the sonar data of the two caverns with respect to the features of the target formation. New criteria for evaluating gas penetration failure and gas seepage are proposed. Results show that the maximum allowable gas pressure of the Jintan UGS salt cavern can be increased from 17 MPa to 18 MPa(i.e. a gradient of about 18 k Pa/m at the casing shoe depth). Based on numerical results, a field test with increasing maximum gas pressure to 18 MPa has been carried out in KING-1 cavern. Microseismic monitoring has been conducted during the test to evaluate the safety of the rock mass around the cavern. Field monitoring data show that KING-1 cavern is safe globally when the maximum gas pressure is increased from 17 MPa to 18 MPa. This shows that the geomechanical model and criteria proposed in this context for evaluating the maximum allowable gas pressure are reliable.Tongtao Wang Jianjun Li Gang Jing Qingqing Zhang Chunhe Yang J.J.K.Daemen 2019Journal of Rock Mechanics and Geotechnical Engineering2019,11,2:4
4Scalable and Identifier/Locator-Splitting Routing Protocol for Mobile Ad Hoc Networks显示文摘In the traditional Internet Protocol (IP) architecture, there is an overload of IP semantic problems. Existing solutions focused mainly on the infrastructure for the fixed network, and there is a lack of support for Mobile Ad Hoc Networks (MANETs). To improve scalability. a routing protocol for MANETs is presented based on a locator named Tree-structure Locator Distance Vector (TLDV). The hard core of this routing method is the identifier/locator split by the Distributed Hash Table (DHT) method, which provides a scalable routing service. The node locator indicates its relative location in the network and should be updated whenever topology changes. Locator space is organized as a tree-structure, and the basic routing operation of the TLDV protocol is presented. TLDV protocol is compared to some classical routing protocols for MANETs on the NS2 platform. Results show that TLDV has better scalability.Wang Haiquan Chen Meng Hu Junshun Xia Chunhe 2012China Communications2012,9,1:3
5Enhanced Photocatalytic Efficiency of TiO2 by Combining the Modification of Ag Nanoparticles with the Application of Anodic Bias显示文摘Ag-TiO2/ITO film electrode was used as photoanode to investigate the feasibility of a hybrid technology of Ag nanoparticles combined with the application of anodic bias. The results showed that the deposited Ag and applied anodic bias have an apparent additive effect.ChunHE YaXIONG DongSHU XiHaiZHU 2003Chinese Chemical Letters2003,14,5:3
6Relationship among Photosys-tem Ⅱ carbonic anhydrase,extrinsic polypeptides and manganese cluster显示文摘Effects of Photosystem Ⅱ (PS Ⅱ) extrinsic polypeptides of oxygen-evolving complex and manganese clusters on PS Ⅱ carbonic anhydrase (CA) were studied with spinach PS Ⅱ membranes. The result supported that membrane-bound CA is located in the donor side of PS Ⅱ. The extrinsic polypeptides played an important role of maintaining CA activity. After removing manganese clusters, oxygen evolution activity was inhibited, but PSⅡ-CA activity was unchanged. It was concluded that CA activity is independent of the presence of manganese clusters, and was not directly correlated with oxygen evolution activity.DAI Xinbin YU Yong ZHANG Rongxian YU Xinjian HE Peiming XU Chunhe 2001Chinese Science Bulletin2001,46,5:2

8Acquirement and characterization of a carotenoid mutant (GM309) of Rhodobacter sphaeroides 601显示文摘A green mutant was obtained among the chemically induced mutants of Rhodobacter sphaeroides 601 (RS601) and named GM309. A blue shift of 20 nm of the carotenoid absorption spectrum was found in the light-harvesting complex II (LH2) of GM309. Different from LH2 of RS601, it was found that the carotenoids in GM309-LH2 changed to be neurosporene by mutation. Neurosporene lacks a conjugate double bond, compared with the spheroidene in RS601-LH2 which has ten conjugate double bonds. As shown by absorption and circular dichroism spectroscopy, the overall structure of GM309-LH2 is little affected by this change. From fluorescence emission spectra, it is found that GM309-LH2 can transfer energy from carotenoids to Bchl-B850 without any change in efficiency. But the efficiency of energy transfer from B800 to B850 in GM309-LH2 is decreased to be 42% of that of the native. This work would provide a novel method to investigate the mechanism of excitation energy transfer in LH2.LIU Yuan ZHANG Wei WU Yongqiang XU Chunhe 2004Science China(Life Sciences)2004,47,1:2

14Influence of different illuminations with xenon or microwave sulfur lamp on jointing and tillering of wheat显示文摘The emission of microwave sulfur lamp is mainly composed of visible light. The sulfur lamp, producing little infrared radiation, has high efficiency, long duration of illumination and less energy consumption. In order to probe the agricultural application of the lamp, experiments were carried out with wheat (cv. Yangmai 158) to emphatically study illuminating effects of xenon or sulfur lamp on tillering, jointing and net photosynthetic rate during tillering and jointing periods. Results indicated that there is almost no difference in net photosynthetic rate of wheat leaves growing under different lamps. Xenon lamp significantly advanced the time of jointing, decreased number of tillers, number of total leaves per plant and leaf size, as well as inhibited root growth. In contrast with xenon lamp, sulfur lamp evidently delays the time of heading and grain maturation, increased number of heads per plant, head length, total number of grains per plant, head weight and total grain weight per plant,CHEN Qilin LIU Yuequn YU Xinjian CHEN Jinxing WENG Jun XU Chunhe 2002Chinese Science Bulletin2002,47,17:2
15Modeling and Global Conflict Analysis of Firewall Policy显示文摘The global view of firewall policy conflict is important for administrators to optimize the policy.It has been lack of appropriate firewall policy global conflict analysis,existing methods focus on local conflict detection.We research the global conflict detection algorithm in this paper.We presented a semantic model that captures more complete classifications of the policy using knowledge concept in rough set.Based on this model,we presented the global conflict formal model,and represent it with OBDD(Ordered Binary Decision Diagram).Then we developed GFPCDA(Global Firewall Policy Conflict Detection Algorithm) algorithm to detect global conflict.In experiment,we evaluated the usability of our semantic model by eliminating the false positives and false negatives caused by incomplete policy semantic model,of a classical algorithm.We compared this algorithm with GFPCDA algorithm.The results show that GFPCDA detects conflicts more precisely and independently,and has better performance.LIANG Xiaoyan XIA Chunhe JIAO Jian HU Junshun LI Xiaojian 2014China Communications2014,11,5:2
