For strained si pmosfets , the hole mobility is not only determined by the tensity of strain , but also related to the strain types , which are uniaxial compressive strain and biaxial tensile strain . when electric field is high enough , the hole mobility will be deteriorated in pmosfets under biaxial tensile strain , however , in the case of uniaxial compressive strain , the deterioration will never occur 经模型分析发现,应变硅pmosfet空穴迁移率与应力作用方式有如下关系:当横向电场较高( > 5 105v / cm )时,双轴张应力作用下的应变硅pmosfet的空穴迁移率将发生退化,而单轴压应力器件则不会受到影响。
The results show that effects of alkali metal salts on conductivity are different because of their different anion radium , crystal lattice energy , ionic mobility and solubility in electrolytes , that different ionic conduction modes of electrolytes result to double - peak of salt concentration dependence of conductivity and different temperature dependence , and that different influences of plasticizer to conductivity result from their different action 结果表明,不同碱金属盐对电解质电导率的影响因其阳离子半径、晶格能、离子淌度以及在电解质中的溶解度的不同而不同;电导率的盐浓度依赖性因电解质的离子传导方式不同而明显呈现双峰形;增塑剂对电导率的影响则因其作用方式不同而产生不同的效果;电导率的温度依赖性也因电解质的离子传导方式不同而呈现不同的规律。
The molecules were acting like enzymes , and yet they were much , much smaller : the molecular weight of a taml is about 500 daltons ( a dalton is equal to one twelfth the mass of carbon 12 , the most abundant isotope of carbon ) , whereas the weight of horseradish peroxidase , a relatively small enzyme , is about 40 , 000 daltons 这些分子的作用方式很像酵素,不过远比酵素小得多:一个taml的分子量大约是500道尔顿( 1道尔顿等于氢原子的质量) ;相较之下,在酵素里算小的辣根过氧化酶,分子量就约有四万道尔顿。
Firstly it discusses the definition of the college campus culture and analyzes its implication , characteristics and function , and points out that college campus culture is subculture of the environment culture , conduction culture , system culture and spiritual culture . its major resources of the cultural construction of college dormitory are campus main - stream culture and subculture , youth culture , social culture and family culture , in content , it is the non - main - stream consciousness and conduction . in ideology , it is the departure from the campus main - stream culture 论文首先从对大学校园文化的界定入手,对大学生宿舍文化的内涵、特点和功能作了尝试性的概括分析,指出大学生宿舍文化是环境文化、行为文化、制度文化和精神文化四个层面组成的校园文化的亚文化,校园主流文化及校园内的某些亚文化群、青年文化、社会文化、家庭文化是其主要源流,具有在内容上表现为非主流意识与行为的凸显、在观念上表现为对校园主流文化某种程度的偏离、在表现形式上反映出社会文化和校园文化的某些特性、在作用方式上以潜移默化的方式发挥其功能等突出特点。
" legal mechanism " consists of two meanings , one is a comprehensive theory about the whole running of law and regulations , including shaping , performing effective adjusting to social relationship , the other stands for certain working methods and ways that the law has to adjust social relationship to some purposes “法律机制”这一概念包含两层含义:一是指从法律规范的形成、实施到产生调整社会关系效果的整个运行的综合原理;二是指法律使其所调整的社会关系达到一定的目标状态而具有的特定作用手段和作用方式。
This paper analyzes the evolution process of mutual combination and interaction between natural ecological enviroment and artifical social environment , and characteristics of the two environments . and it suggests that the suitable ways of coordination and sustained development between two environments should be a suitable and sustained utilization of natural resources , which will promoted the sound and sustained development of human society 分析了自然生态环境和人工社会环境的相互结合和相互作用方式的发展演化过程以及其两大环境相互结合和相互作用方式的特性.在此基础上,提出了自然生态环境和人工社会环境协调与持续发展的适宜方式是人类对自然资源的适度开发,永续利用,来推动人类社会的健康与持续发展
The elements can be classified into four grades according to the importance of their influence on the whole function system . on the base of the results of correlation analysis on the data obtained through a questionnaire survey on tourists and residents , restraining elements and promoting elements can be divided . city function system of international destination cities thus can be defined as the structured system composed of inter - affected elements , which complete the essential function of an international destination city 根据旅游者及居民对城市功能要素的评价和对总体功能评价的问卷调查结果,这些复杂的要素可以按其对总体功能作用力的大小分为四个等级,并且不同功能要素对于城市总体功能的作用方式各不相同,包括对总体功能主要起明显抑制作用的抑制性因素以及起明显提升和完善作用的激励性因素和兼有两种作用的复合性要素。
The electroless plating nickel ' s reaction can take place in the active suthee of metal , the activity of the surface of metal lied on three factors , including the properties of il metal ' s edce , the choice of reducer and the manner of action between reducer and metal ' s sdse 化学镀反应在活性表面上发生,金属表面的活性取决于金属表面的性质、还原剂及还原剂与金属表面的作用方式三个要素。本文针对目前有关化学镀镍机理研究中的一些可能的化学反应步骤提出了自己的看法,对有关实验现象作出的解释与实验现象基本相符。
By means of historical literature , the author analyzed the achievements made and insufficiencies existed in rural sports practice in china since the establishment of china , and put forward the following opinions based on his analysis : for the development of rural sports practice in china in the future , governmental functions should be intensified , and the mode of governmental functions should be institutionalized , standardized and legalized ; the construction of rural fundamental sports organizations should be strengthened , and rural fundamental sports activists should be cultivated ; local and national sports activity events should be fully explored , coordinated and promoted , so as to enrich rural sports activity contents ; rural sports activities should be properly developed according to the time , location , people and program , so as to add new contents to the celebration of traditional rural holidays ; attention should he paid to the issue of development of sports for disadvantageous groups and migrant laborers in rural society ; attention should also be paid to rural scholastic physical education and full utilization of rural scholastic physical education resources 摘要通过历史文献,分析了建国以来中国农村体育实践所取得的成就和不足,在此基础上提出:未来中国农村体育的发展要强化政府的作用,政府的作用方式要制度化、规范化和法制化;要加强农村体育基层组织建设,培育农村基层体育骨干;要充分挖掘、整理和推广地方性、民族性的体育活动项目,丰富农村体育活动内容;要因时、因地、因人、因项目制宜地开展农村体育活动,为农村的传统节日庆典注入新内容;重视农村社会弱势群体和异地民工的体育发展问题;重视农村学校体育,充分利用农村学校体育资源。
