1Numerical description of coalbed methane desorption stages based on isothermal adsorption experiment显示文摘Quantitative description of desorption stages of coalbed methane is an important basis to objectively understand the production of coalbed methane well,to diagnose the production state,and to optimize the management of draining and collection of coalbed methane.A series of isothermal adsorption experiments were carried out with 12 anthracite samples from 6 coalbed methane wells located in the south of the Qinshui Basin,based on the results of isothermal adsorption experiments,and an analytical model was developed based on the Langmuir sorption theory.With the model,a numerical method that adopts equivalent desorption rate and its curve was established,which can be used to characterize the staged desorption of coalbed methane.According to the experimental and numerical characterizations,three key pressure points determined by the equivalent desorption rate curvature that defines pressure-declining desorption stage,have been proposed and confirmed,namely,start-up pressure,transition pressure and sensitive pressure.By using these three key pressure points,the process of coalbed methane desorption associated with isothermal adsorption experiments can be divided into four stages,i.e.,zero desorption stage,slow desorption stage,transition desorption stage,and sensitive desorption stage.According to analogy analysis,there are differences and similarities between the processes of coalbed methane desorption identified by isothermal adsorption experiments and observed in gas production.Moreover,it has been found that larger Langmuir volume and ratio of Langmuir constants are beneficial to earlier advent of steady production stage,whereas it is also possible that the declining production stage may occur ahead of schedule.ZHANG Zheng QIN Yong Geoff X WANG FU XueHai 2013Science China Earth Sciences2013,56,6:25
2An ABA-mimicking ligand that reduces water loss and promotes drought resistance in plants显示文摘Abscisic 酸(骆驼毛的织物) 是最重要的荷尔蒙让植物抵抗干旱和另外的不能生活的压力。骆驼毛的织物直接绑在骆驼毛的织物受体的 PYR/PYL 家庭,导致类型 2C 磷酸酶(PP2C ) 和下游的骆驼毛的织物发信号的激活的抑制。骆驼毛的织物由小分子发信号的干预能帮助植物克服象干旱,寒冷和土壤咸度那样的不能生活的压力,这被想象。然而,由植物酶的化学不稳定性和快速的分解代谢限制骆驼毛的织物本身的实际申请。这里,我们报导一件小分子骆驼毛的织物的鉴定模仿(AM1 ) 那充当骆驼毛的织物受体的家庭的多重成员的有势力使活跃之物。在 Arabidopsis, AM1 激活高度类似于由骆驼毛的织物导致了那的一个基因网络。有 AM1 的处理禁止种子萌芽,阻止叶水损失,并且支持干旱抵抗。我们与 PYL2 骆驼毛的织物受体和 HAB1 PP2C 在建筑群解决了 AM1 的水晶结构,它表明 AM1 调停交往的 gate-latch-lock 网络,在骆驼毛的织物界限 receptor/PP2C 建筑群被保存的一个结构的特征。一起,这些结果证明一件单个小分子骆驼毛的织物模仿能激活多重骆驼毛的织物受体并且保护植物免受水损失和干旱应力的伤害。而且, AM1 复杂水晶结构为设计 ABA-mimicking 小分子的下一代提供一个结构的基础。Minjie Cao Xue Liu Yan Zhang Xiaoqian Xue X EdwardZhou Karsten Melcher Pan Gao Fuxing Wang Liang Zeng Yang Zhao Pan Deng Dafang Zhong Jian-Kang Zhu H Eric Xu Yong Xu 2013Cell Research2013,23,8:17

4Overview to the Hard X-ray Modulation Telescope (Insight-HXMT) Satellite显示文摘As China’s first X-ray astronomical satellite, the Hard X-ray Modulation Telescope (HXMT), which was dubbed as Insight-HXMT after the launch on June 15, 2017, is a wide-band(1-250 ke V) slat-collimator-based X-ray astronomy satellite with the capability of all-sky monitoring in 0.2-3 Me V. It was designed to perform pointing, scanning and gamma-ray burst(GRB)observations and, based on the Direct Demodulation Method (DDM), the image of the scanned sky region can be reconstructed.Here we give an overview of the mission and its progresses, including payload, core sciences, ground calibration/facility, ground segment, data archive, software, in-orbit performance, calibration, background model, observations and some preliminary results.Shuang-Nan Zhang TiPei Li FangJun Lu LiMing Song YuPeng X u CongZhan Liu Yong Chen XueLei Cao QingCui Bu Zhi Chang Gang Chen Li Chen TianXiang Chen YiBao Chen YuPeng Chen Wei Cui WeiWei Cui JingKang Deng YongWei Dong Yuan Yuan Du MinXue Fu GuanHua Gao He Gao Min Gao MingYu Ge YuDong Gu Ju Guan Can Gungor ChengCheng Guo DaWei Han Wei Hu Yue Huang Jia Huo ShuMei Jia LuHua Jiang WeiChun Jiang Jing Jin YongJie Jin Bing Li ChengKui Li Gang Li MaoShun Li Wei Li Xian Li XiaoBo Li XuFang Li YanGuo Li ZiJian Li ZhengWei Li XiaoHua Liang JinYuan Liao GuoQing Liu HongWei Liu ShaoZhen Liu XiaoJing Liu Yuan Liu YiNong Liu Bo Lu XueFeng Lu Tao Luo Xiang Ma Bin Meng Yi Nang JianYin Nie Ge Ou JinLu Qu Na Sai RenCheng Shang GuoHong Shen Liang Sun Ying Tan Lian Tao YouLi Tuo Chen Wang ChunQin Wang GuoFeng Wang HuanYu Wang Juan Wang WenShuai Wang YuSa Wang XiangYang Wen BaiYang Wu BoBing Wu Mei Wu GuangCheng Xiao ShaoLin Xiong LinLi Yan JiaWei Yang Sheng Yang YanJi Yang QiBin Yi Bin Yuan AiMei Zhang ChunLei Zhang ChengMo Zhang Fan Zhang HongMei Zhang Juan Zhang Qiang Zhang ShenYi Zhangs Shu Zhang Tong Zhang WanChang Zhang Wei Zhang WenZhao Zhang Yi Zhang YiFei Zhang YongJie Zhang Yue Zhang Zhao Zhang Zhi Zhang ZiLiang Zhang HaiSheng Zhao XiaoFan Zhao ShiJie Zheng JianFeng Zhou YuXuan Zhu Yue Zhu RenLin Zhuang 2020Science China(Physics,Mechanics & Astronomy)2020,63,4:2
