On the basi s of these results , time - dependent glias changes in the brain were observed with the same model by investigating the expression of s - 100 protein , a specific marker for glias , mainly for astrocytes . our results shown : compared with those of the unradiated rats , the number of s - 100 protein immunoreactive positive glial cells in the brains of the irradiated rats increased gradually . more s - 100 - positive glial cells with multiple long processes and hypertrophic cell bodies were also observed in these areas 在此基础上，又做了同一照射剂量（ 20gy ）照射大鼠半脑后不同存活期间（ id ， 7d ； 14d ， zld ， 28d ）大鼠全脑s 100动态变化的观察，发现其规律如下：在上述时间点大鼠脑内各部位卜刁m蛋白免疫反应细胞数量进行性增加，伴有s 100免疫阳性细胞的胞体逐渐增大和交起增多，与正常对照组具有明显的差异。

Human resource management pays attention to give the employe - es sound organization , training and collocation with a modern methods on the basi - s of suitable human resource planning for the sake of the best match of position an - d personnel . through a series of management mechanism , it can stimulate the employee ' s job motivation . as a result , a person has a right position and a post correspon - ds to a right person with right ability 人力资源的开发和管理是指，在合理制定人力资源规划的基础上，运用相关现代化的科学方法，对员工进行合理的培训、组织与调配，实现组织岗位与员工的最佳匹配，并通过制定一系列管理机制，激发员工的工作动机，充分发挥员工的主观能动性，使人尽其才，事得其人，人事相宜，以保证组织目标的实现。

Abstract : a semi - analytical method is used to modelling the pract ical 3 - zone simulated moving bed chromatography ( smbc ) process for optimal searc hing . the switch time which is the most important operation parameter of 3 - zone smbc is analyzed based on the nonlinear batch chromatography theory firstly , and then adjusted by the deviation between the output and the expectation . the switch time approaches the optimization very soon by continously searching on the basi s of the theory . the parameters of the practical system are inputted into simulat ion , the result is used in our experiment and a good separation is obtained 文摘:针对三带模拟移动床色谱的实际模型，用一种融合了前馈与反馈的半解析优化计算方法对三带模拟移动床色谱过程进行了模拟.首先，由非线性单柱色谱理论解析地给出一个三带模拟移动床色谱的主要操作参数即切换时间值，然后利用所得结果与目标量之间的偏差来校正切换时间，在理论指导下进行优化搜索，切换时间能很快达到最佳值.将测得的系统参数引入计算，并将计算结果用于实际操作，得到了很好的分离效果
