  在更宽的温度范围、压差范围内，在不同原料气组成(即不同的氢气分压)条件下，对所制备的锆表面改性膜进行了渗氢性能实验，考核了膜对氢的唯一选择渗透性，结果表明：在四极质谱的检测下限内，只有氢气存在，而无杂质气体通过；在593k 773k温度范围内，锆表面改性选择渗氢膜具有高于钯膜数十倍至十几倍的渗氢流量和渗氢系数；其渗氢流量随着膜两侧氢分压平方根摘要差的增大而增大，并且呈线性关系；压力对膜的渗氢系数几乎无影响；膜的渗氢系数随着温度的升高而下降，井巨呈指数关系：根据对实验数据所作渗氢系数与温度关系曲线的拟合，在温度593k 773k范围内，压差p 、 0二0
• The zircondri filin wtut rirconia wa prepared and the removing technology of the zirconia on the zirconium sdrices was obtalned . the methods of chemistry and magnetron sputtring plating were used in order to platc a palladium film , which is characteristic of self catalysis for hydrogen and the sole h - permselectivity on the clean rirconium sdrices prepared by the methods of electrochemitw and ( or ) high temperatur vacuum hydrgenization , which was firstly studied . the plating tedrilogy was obained and the surface modified zirconium membran was prepared
  在利用电化学法和真空高温除氧加氢法去除了锆表面氧化膜的基础上，分别采用化学法、磁控溅射法两种镀膜技术在其表面上镀上了一层对氢具有自催化分解、唯一选择渗透性的金属钯膜，首次获得了锆基材膜表面上镀钯的制备工艺，成功制备了锆表面改性选择渗氢膜。
• It was accordingly revealed that the heritability of early maturity suffered strong environmental impact and thus in environmentally different locations it was not reliable to use the position of the first fruiting shoot and the period from sowing to budding as the criteria of early maturity but feasible and practicable to use growth period and flowering time as the index of early maturity
  由此说明：早熟性的遗传受环境影响较大，在生态条件差异较大的育种地点，以果枝始节和播种现蕾作为早熟性指标进行异地选择是不可靠的，而以生育期、开花期为早熟性选择指标是比较可行的。
• Lmpa , the relationship is f di = l 55xl0 - " e47j l t ) in this range , the relative error of the hydrgen permeabilty bbeen the experimental values and the formula values are less than 3 % , the durability test showed that after the cycle experiments of prcssure and tempebe for 30 days , the perfrmance of the membran did not change , at last , the theory of hydrogen permeaton was discussed , too . through this work , the pfepared surf ases modified zirconium memran can satisfy the requirement of the purity and the permeating fiux of hydrogen isotope gas
  Imp范围内，铝表面改性选择渗氢膜的数学表达式为： （ 1320 i 155x10 ” exd l “ t ）在这个温度和压差范围内，渗氢系数的实验数据计算值与数学公式计算值的误差在3以内；铬表面改性选择渗氢膜的寿命考核实验表明，经过连续30大的循环温度、压力实验，膜的质量、性能无变化；并讨论了膜的渗氢理论。
• Before implementing hrm strategies , we should first study the hrm strategically , and then make strategical choices . so in the fourth section , the thesis undertakes the strategical study of hrm , expounds from three aspects : the necessity of implementing strategy , the integration of the human resources and strategy management course and program , and the practice of strategical human resourses
  武汉理工大学硕士学位论文实施战略性的人力资源管理首先必须对人力资源管理进行战略性研究，然后才能作出战略性选择。于是第四章着重人力资源管理的战略研究。从战略实施的必要性，人力资源与战略管理过程和规划的联系，战略人力资源实践三个方面进行了研究。
• In this research the theory of unintended consequence of middle range theory in sociology was adopted to analyze the phenomenon that the rich benefits from the project while the poor not . the willingness of resettled household and intervention of the government are the two key characters in the voluntary resettlement project . so the theory of social capital and the strategy of economical development will be used to explain the behaviors of household and government and then summarize the causes of unintended consequence
  在这样的一个整体理论框架的指导下，从自愿性移民中的自愿性和政府干预性两个方面分别讨论出现未预结局的原因：用社会资本理论来分析基于自愿性选择上的农户行为的特点，得出贫困农户本身在人力资本和物质资本缺乏的条件下，由于社会资本的不足而得不到足够的社会网络的支持，不能实现移民或不能达到移民的预期效果；而富裕的农户却能在人力资本、物质资本以及由此决定的社会资本的支持下能够进行移民。
