The phases of sulfuric acid slag of various sizes were drawn by seven - step method in the improved separation condition of disturber , and phases of thallium were compared before and after the slag was grinned to analyze phase migration 为了进一步探讨颗粒物中铊相态提取的技术和方法，在优化干扰物分离条件下，采用七步法提取了几种不同粒径硫酸废渣中铊的相态，比较了废渣研磨前、后各相态铊的异同。
With the apart of ownership and proprietor , the problem of surrogate appears . in order to solve the problem , client must design effective restriction mechanism for attorney . the restriction mechanism can ensure maximum revenue of client when attorney purse their maximum revenue 为了解决两权分离条件下产生的“代理问题” ,委托人需要设计一套对代理人行为进行有效约束的机制,保证代理人在追求自身利益最大化的同时,实现委托人利益的最大化。
The electric field distribution at the cross is simulated and analyzing using the soft of ansys5 . 7 . then the electrophoretic method has been optimized . the electrophoresis and the volume of injection have been significantly controlled using this method 设计了微通道电泳芯片的电泳操作方法，并用有限元分析软件对在进样和分离条件下，进样口处的电场强度分布进行了模拟分析，在此基础上对电泳操作方法进行了优化，实现了进样量和电泳过程的有效控制； 6
Because there are so much factors effecting the resolution and so complex of migration characteristic that it is hard to carry out dna sequencing . it has to further optimize the electrophoretic conditions . great progress in several related techniques , mce chip has a broad application in the future 但是影响电泳分高效率的因素很多，同时样品在电场作用下的运动特性很复杂，要实现dna片段的单碱基分辨，甚至实现dna序列的快速测定，还需要进一步优化电泳分离条件。
Since viscosity of emulsion is important to elm separation process , it is necessary to research the viscosity of emulsion . during the study of separation of copper in the model industry waste by emulsion liquid membrane , some operating parameters are investigated , including the value of ph in the external phase , the concentration of acid in the internal phase , the concentration of copper in external phase , the concentration of surfactant , the kinds of carriers in the membranes phase as well as the concentration of carriers 对乳液膜体系分离铜离子的研究，主要是考察分离条件(如外水相的ph 、内水相酸的浓度，外水相铜离子的浓度，载体种类、载体浓度、表面活性剂的浓度等)对铜离子提取程度的影响，通过实验得到，外水相的ph值是乳液膜分离铜离子的一个重要原因，这主要是由于cu ( oh ) _ 2溶度积和界面反应的化学平衡决定的。
When the given point set is a local separate sample of a closed surface set or an overall separate sample with known radius of sampling hole , the algorithm will reconstruct a correct result ; when the separate condition is not satisfied at some points , the algorithm will give result with corresponding holes 当所给点集是闭曲面集的局部分离样本或已知采样空洞半径的全局分离样本时，本算法将给出正确的重建结果；当所给点集在某些样点处不满足分离条件时，算法将给出相应的空洞以供参考。
The adsorption of polymer chains at the sio2 surface avoided the coherence between the nascent hollow fibers , improved spinning conditions and hollow fiber bearing . the addition of ca further improved mechanical property of membrane , but pressure - resiposivity became weak . by controlling polymer and sio2 通过对sio _ 2填充pu溶液纺丝成形研究发现，因sio _ 2对pu纺丝液相分离条件的改变及对pu大分子的吸附，有效防止了pu初生纤维的粘结，提高了pu纺丝溶液的可纺性，改善了pu中空纤维膜的支撑性。
