The electronic - ceramic capacitive - type sensor for coi is based on the nanometer and semiconductor theories . according to the mechanism of the gas surface absorbing actions and the mechanism of grain boundary effect of semiconductors , the capacitance of the sensor can be changed with the variation of co2 concentration Co _ 2气敏陶瓷电容型传感器将纳米理论和半导化理论引入了传感器的研制过程中,这种传感器通过气体表面吸附,及在半导体介质的晶界层产生的晶界效应,使得不同浓度co _ 2气体产生不同的电容值。
On the basis of frequent field - studies , in the light of the basic theories of ecological design , it tells the benefits and necessity of ecological design for city squares , and demonstrates the basic aims ( aim of function , aim of image , aim of environment ) ; according to the weather and vegetation characteristics of subtropical zone , it tells the cardinal principles ( humality , sustainable development , characteristics distinguishing , integral harmony , public participation ) for the design ; with regard to the architecture enclosing , the space organizing , the boundary effects of city squares , and their size and color , this dissertation also analyzes the space and environment of city squares , and especially discusses the ideas of how to decide the size of a square regarding the problem of building big city squares blindly ; and summarizes the key points of ecological plan and design for the component factors of the space and environment of city squares , and the problem of greening of squares is paid much attention 在多次实地考察的基础上,本文从生态设计的基本理论出发,指出了城市广场生态设计的意义及必要性,明确了设汁的基本目标(功能目标、形象目标、环境目标) ;结合亚热带区域的地理气候与植被特征,提出了亚热带区域城市广场生态设计的基本原则(人性化、可持续发展、突出特色、整体协调、公众参与) ;分别从尺度、色彩、与周边建筑的围合、空间组织、边界效应及内部交通等方面对广场的空间环境进行了分析,其中针对当今我国广场建设中“盲目求大”的现象,重点分析了如何把握广场的尺度问题;总结了广场的绿化、地面铺装、建筑小品、水体等空间环境构成要素的生态设计要点,其中着重讨论了当今广场建设中颇为严重的绿化问题。
The ionic conductivities of lsgm enhanced with the measuring temperature . based on the results of electrical measurements , the relative contribution of the grain interior and grin boundaries to the overall resistance was discussed in detail in relation with the grain boundary effect and mg doping contents . the grain boundary effect decreased monotonously with the increase of mg doping in the range of testing temperature 在相同测试温度下, lsgm体系离子电导率随着镁含量的增加而增大,在y = 0 . 2时达到最大值,此后电导率随镁含量的增加而降低;在测试温度范围内,所有lsgm样品的离子电导率均随温度的升高而增加。
