In this work, the interaction between umbelliferone and bovine serum albumin was studied by performing two different kinds of titration modes. The two spectroscopic data matrices were augmented, and then the information of experiment data was increased. The augmented experiment data matrix was analyzed by the MCR-ALS method. This procedure allowed the recovery of the concentration profiles for each species and the calculation of the ∶ ratio in the complex and the apparent equilibrium constant.

Of of top-ranking outstanding achievement 1985 January, the Long Conghai that wear a root army be transferred to civilian work of some submarine unit come back, deputy stationmaster of station of Ren Funing channel, this cadre that enlists in army from navy is having a kind of special feeling to water it seems that, inside a month after be transferred to civilian work, he is taking boat politics a light boat, inspected entire county the channel of line of the Heavenly Stems and Earthly Branches of 590 much kilometers, visited a county main transportation enterprises is mixed boat civilian is bit more distributing center, understand conserve of the channel inside the county and the current situation that supervise the work very quickly, having doinging oneself while be assigned personal responsibility for works, raised the proposal of a lot of innovation to main and responsible comrade.

一流业绩 1985年元月，戴根龙从海军某潜艇部队转业回来，任阜宁航道站副站长，这位从海军服役的干部似乎对水有着一种非凡的感情，在转业后一个月内，他乘着航政艇，考察了全县 590多公里的干支线航道，走访了县主要运输企业和船民集散点，很快摸清县内航道养护和治理工作的现状，在做好自己分管工作的同时，并向主要负责同志提了许多创新的建议。

They are probably right in guessing that Mr Obama's instincts for inclusion and dialogue will mean a form of engagement that is more akin to George Bush's Korean policy in his second term than the confrontational approach of his first, during which North Korea became a charter member of the "axis of evil".

或许有一种猜测是正确的，那就是奥巴马包容和对话的天性将意味着某种形式的协定，同乔治·布什在他第二任期内的政策极为相像，而不是在布什第一任期内截然相反的政策。在那段时期，朝鲜成了邪恶轴心国家的主要成员。

The paper includes:The author calculate the structures inner force and displacement of the free end , analyze the influence of the height and the value of pretress of cable by making use of ANSYS 9.0 soft, pose the concept of critical prestress,conclude the function relation between displacement of the free end, initial strain and the height of cable ,analyze the dynamic properity and point out that Newmark-β method should be adopted when we analyze the dynamic properity of the cable-stayed spatial structure with direct integral test to guarantee the contribution of high mode,finally conclude the functional relation among coefficient of earthquake inner force, initial strain and the height of cable, wish to get some helpful conclusion applied to cable-stayed spatial truss design.

本文系统介绍了斜拉空间桁架竖向地震反应的分析理论与方法、详细分析了斜拉空间桁架结构在静力和竖向地震作用下的受力性能，主要内容包括：利用通用有限元软件ANSYS9.0计算了斜拉空间桁架在静力和竖向地震作用下内力及自由端位移分布规律并得出地震内力系数与节间位置、预应力以及斜拉索高度之间的函数关系；详细分析了斜拉索中施加的预应力以及斜拉索高度的变化对于该种结构内力及自由端位移的影响并提出了斜拉空间桁架的临界预应变概念，进而得到了自由端位移与初始预应变以及斜拉索高度的函数关系，即：△=-(40h+2180)ε+9.8；分析了该种结构的动力性能，并指出：在时域内采用直接积分法计算该种结构的动力响应时，应该考虑采用不引起振幅率减小的Newmark-β法，以保证高阶模态响应的贡献仍然保留在响应中而不致于被忽略。

But the result of improvement soil translated alkaline soil into alkalier soil. Not onlu it is unavoidable and subsisted of stabilization in commix tier of gypsum, but also it destroyed direct improvement process. It is imported find what solved seepage problem of gypsum in the study. In configured duality structure of improvement soil, it needs abundance seepage gypsum in commix tier into noncommix tier in order to losing seepage capacity reduce in all deepness of improvement soil.

碱土改良过程中石膏渗漏损失最高可达到石膏施入量的40%以上，而改良结果碱土只转化为重碱化土；在石膏混合层内，它是一种不可避免的、稳定存在的且直接破坏土壤改良进程逆流；因此解决石膏渗漏问题亦是在本文研究工作中的重要发现：配置二元结构改良碱土中，正需要石膏混合层中大量石膏渗漏，以改良非石膏混合层，并使整个计划改良深度内的渗漏损失降为零。

FRAP is a technique widely usedin cell biology to observe the dynamics of biological systems, including the diffusionof membrane components.

FRAP是在细胞生物学中被广泛用于测定生物体系动态性包括生物膜组分动态扩散的一种技术，其原理是利用高强度激光将细胞内一小部分区域的荧光分子漂白，然后通过记录该区域随后的荧光恢复，检测周围未漂白区域内的荧光分子与漂白区域荧光分子的交互扩散。

During the clustering formation,it fully considers the underlying network topological properties and avoids all possible data packet delivering on costly links to reduce multicast delayIn addition,group members are constructed to an efficient Fibonacci multicast tree utilizing a novel multicast algorithm based on Fibonacci Series,and the tree is used to carry on the intragroup multicast.
