The main achievement is as following: Present a new software structure with insert mode based on diagram and data platform. With this structure the software can be used in various voltage levels of power networks by switching function groupware with corresponding edition. Therefore it is important to solve software universality and developability.(2) Present a new idea that any operating condition is combination of running mode of plant or station, power supply topological and rules of equipment maintenance. This idea is very useful at simplifying setup and choice of operating conditions and ensuring calculation result correction.(3) Present a new idea of protection setting examination and rectification. Protection setting examination is used to examine the selectivity、 sensitivity and speed under certain operating condition, and pass an opinion whether these settings are wrong;Setting rectification is used to calculate new relay settings when error is found in setting examination.(4) Point out that interaction design is the key step in developing power system application software,which can secure usability.

To test the respirators fitness, we used quantitative fit test system to measure the fitness of the three models of new respirators worn by real person. The testing method is to use a differential mobility analyzer to select the particles of 40nm in diameter. N95 respirators are capable of filtering out almost all 40nm particles, therefore, the 40 nm particles measured within the respirator would be considered due to the leakage caused by poor fitness.
口罩密合度是使用定量密合度测试组合系统以真人分别配戴三款五年口罩A、B与C和同样型号新口罩来测试其密合度,测试方法主要是利用差异电移动度分析仪筛选粒径为40nm的微粒,而N95口罩的特性几乎可以完全过滤40 nm的微粒,所以口罩内量测到40nm粒径的微粒可被认定是泄漏造成。

The spatial narrative structures in Calvino's fictions can be divided into three types :"the building of two worlds "is the main way in the earlier writing phase of Neorealist and Fairy tale .Dimidiation and mergence is the art feature .It signs that the sense of the world and the creative ideas of the writer start to form;"Synchrony and Juxtaposition "and "Crystal pattern "are the prominent characteristics during his Postmodernism writings phase. The writer takes the complex and diverse form of space art, such as segments、juxtaposition、defamiliarization、crystal's combination and derivatives, ect. to represent the essence of the world, and to exprsee the writer's confusion and efforts to understand and build a sense of it.
