In order to understand the seismic performance of the large complex structure with basement, the structure-pile-soil finite element model of two typical cross sections of the Tianjin Transportation Junction were established by using the ANSYS software. The elasto-plastic time history analysis was made, and the seismic responses of the whole system under the horizontal seismic load were got. Comparing the results of the seismic response with the rigid foundation model, some reasonable conclusions are drawn.

By use of the Fischer-Tropsch reaction in a C-H-O system, we discussed the relationships between inorganic CO〓 and some physical chemistry conditions, such as Oxygen flee degree , temperature, pressure, other objects consistency and catalyzer. a when T=200K～2000K, if f〓＞0, the reaction of generating CO〓 will be dominant, CH〓 hardily exists; b when T＞1000K, CH〓 is not propitious to exist, carbon in system almost exists in form of CO〓; c the more pressure, the more CO〓 is propitious to exist; d the more consistency of CO, O〓 and H〓O, the more CO〓 is propitious to exist, the more consistency of H〓, the more CH〓 is propitious to exist.

依据C-H-O体系费托反应的简化模型，讨论了氧逸度、温度、压强、其它物质浓度、催化剂等物理化学条件对无机成因CO〓生成的影响，从理论上讨论了在地质环境中，无机成因CO〓存在的物理化学条件：1在T＝200K～2000K的温度范围内，体系中一旦氧逸度＞0，生成CO〓的反应将占绝对优势，CH〓几乎不可能存在；2T＞1000K时，不利于CH〓形成，使体系中的碳主要以CO〓的形式存在；3体系压强越大，越有利于CO〓的形成；4反应物CO、O〓、H〓O的浓度越高，越有利与CO〓的存在，H〓的浓度高有利于CH〓的形成。5地质成藏作用可以经历很长的地质年代，这足以补偿矿物岩石中的Ni、Mo、Fe、Co、Ru等催化性能的降低及其它动力学条件的不足，使得费托反应可能发生，从而生成无机成因的CO〓和烃类。

Glucokinase, also called hexokinase Ⅳ, which catalyses glucose phosphorylation in hepatocytes and pancreatic β cells, is a key component of the glucose sensing machinery in mammals and plays a fundamental role in glucose homeostasis.

葡萄糖激酶(Glucokinase，GK)即Ⅳ型己糖激酶(Hexokinase，HK)，主要作用是催化肝细胞和胰岛β细胞内的葡萄糖磷酸化为6磷酸葡萄糖，该步反应是细胞内葡萄糖代谢的初始反应，也是限速步骤之一，因此葡萄糖激酶又称为细胞的葡萄糖感受机制，在维持血糖稳定方面起着关键的作用。

And the antioxidant enzymes were also activated. We found that there was some signaling pathway within the damaged plant and interplant. Diphenylene iodonium, an inhibitor of NADPH oxidase, could significantly inhibit H2O2 burst and enzymes activities that mediated by herbivore-infested. H2O2 has also been proved to play the signal role in defensive response.

茉莉酸信号传导途径在植物防御反应中有着重要的作用，对植株用茉莉酸甲酯熏蒸后，可诱导植株产生与昆虫取食类似的反应--叶片过氧化氢含量有明显的提高，同时对POD、PPO、PAL等直接防御物质有显著的诱导作用，进而证明了茉莉酸甲酯是伤信息在植株间传递的报警信号分子之一。
