Chorismate acid is branch point in aromatic amino acids biosynthesis , related to phenylalanine , bifunctional enzymes chorismate mutase / prephenate dehydratase ( encoded by phea ) is rate - limiting enzyme 分支酸是芳香族氨基酸合成途径的分支点，与苯丙氨酸合成有关，双功能酶分支酸变位酶-预苯酸脱水酶( phea基因编码)是关键酶。
The mechanical behavior characteristics , stabilization state of surrounding rock , deformation mechanism of anchorage , topology effect of tunnel anchorage system of suspension bridge were studied based on numerical simulation method 摘要采用数值模拟方法研究了悬索桥隧道式锚碇系统的力学行为特征、围岩稳定状态、锚碇变位机理和拓扑效应。
In the recent years , along with the construction of breasting dolphin , people put more and more attention to the interactional relation between laterally loaded piles and soil . but there is no domestic criterion about calculational methods of breasting dolphin 50年代前，桩只作为承受轴向力的构件，随着钢桩在实际工程中的应用，桩的水平承载性能越来越引起人们的重视，尤其是柔性靠船桩在大变位情况时，国内尚无针对这种结构的设计、施工规程。
For do n ' t delive the horizontal power , connect method adopt the double hingle connect , and made both girder just to deliver the horizontal power each other , and vertical power can change position , this the problem that the top bear armor plate beam do n ' t accommodate the increasing in speed had been resolved radical 为了不传递竖向力，连接方式采用双铰接，使两孔梁只能相互传递横向力，竖向可以变位，从而基本解决了上承式钢板梁不适应提速问题。
Firstly , the displacement , stress , strain fields and the working state of dam body and foundation are evaluated by fem . by overloading the upstream water level and reducing rock strength parameters , the failure process of dam foundation is simulated and the failure mode and paths are determined . the results show that when overload method is used , damaged area develops from up - stream to down stream with failure front stays near the interface between dam body and bedrock 首先采用非线性有限单元法对坝体及坝基在不同荷载工况下的变位、应力应变状态展开分析，评价各工况下坝基的运行状态，而后采用超载法和综合法对大坝稳定性进行分析，模拟坝基的渐进性破坏过程，追踪岩体破坏状态的发展演变过程，从而得到坝基在超载和强度下降过程中的破坏模式和破坏发展路径。
Photorefractive phase conjugation , which is one of the most important methods for producing phase conjugation wave , is of potential use in many fields due to its low build - up threshold , high fidelity and high damage threshold , etc . in this thesis , we present a complete research to the characteristics and applications of ce : bati03 self - pumped phase conjugation ( sppc ) 光折变位相共轭具有建立阈值低、保真度高和大损伤阈值等优点，因而具有广泛的用途。在本论文中，我们针对ce ： batio _ 3晶体光折变自泵浦位相共轭器的特性和应用做了全面深入的研究。
This paper introduces the development and present situation of vibration absorb technology in the world ; generally analysis the rubber - bearing ( rb ) and lrb " s operative mechanism , function and the calculation of parameter ; advance the concept of standardization to lrb ; on the basis of generally analyzing the connected factor such as the site category , the diameter of lead bar , the height of bearing , the designing carrying capacity , the span of bridge , the inherent period and the displacement of rb , determine the parameter , the absorbing vibration target , the method and the process of standardization to lrb ; then according to the two - step rule of resisting and defending earthquake , and combining with the response spectrum theory in the seismic vibration of bridge , make a lot of calculation and analysis of vibration absorb design to the real bridge collected and combined by finite element program ; at last , gives the result of standardization through diagram and explains to its usage 本论文介绍了国内外减震技术的发展和现状；综合分析了普通板式橡胶支座和铅销橡胶支座的工作机理、性能及参数的计算；提出了铅销橡胶支座标准化的概念；在综合分析场地土、铅销直径、支座高度、设计承载力、桥梁跨径、固有周期以及支座变位等影响因素的基础上，确定了铅销橡胶支座标准化的参数、减震目标、方法和过程；并根据抗震设防两阶段原则，结合桥梁地震振动理论的反应谱法，运用有限元程序对收集和组合的实桥进行了大量减震设计的计算和分析；最后以图表的形式给出了铅销橡胶支座标准化的结果，并说明了其使用方法。
