RSB芒刺线具有哪些特点?

答案

参考答案:

RSB芒刺线不仅具有传统RS芒刺线所具有不断线、不变形、刺尖上下不易积灰、振打性能好、放电强度大的优点,而且还克服了其放电均匀性差,平均电场强度弱的缺点。使得RSB芒刺线既能适应不同工况的要求,而且又具有放电均匀性好、尘粒荷电迅速充分、平均电场强度大的优点。在芒刺线的主干管背部有背刺,其主要是为了改善电晕电流的密度的均匀性,增强平均电流密度,可有效提高除尘效率。

单项选择题

People are indulging in an illusion whenever they find themselves explaining at a cocktail(鸡尾酒)party,say, that the are “in computers,”or“ in telecommunications,”or “in electronic funds transfer”. The implication is that they are part of the high-tech world. Just between us,they usually aren’t. The researchers who made fundamental breakthroughs in those areas are in a high-tech business. The rest of us are (71)of their work. We use computers and other new technology components to develop our products or to organize our affairs. Because we go about this work in teams and projects and other tightly knit working group(紧密联系在一起的工作小组),we are mostly in the human communication business. Our successes stem from good human interactions by all participants in the effort,and our failures stem from poor human interactions.

The main reason we tend to focus on the(72)rather than the human side of work is not because it’s more (73),but because it’s easier to do. Getting the new disk drive installed is positively trivial compared to figurine out why Horace is in a blue funk(恐惧)or why Susan is dissatisfied with the company aver only a few months. Human interactions are complicated and never very crisp(干脆的,干净利落的)and clean in their effects, but they matter more than any other aspect of the work. If you find yourself concentrating on the(74)rather than the(75).you’re like the vaudeville character (杂耍人物)who loses his Keys on a dark street and looks for them on the adjacent street because,as he explains,“The light is better there!”

(75)处填()。

A.technology 

B.sociology 

C.physiology 

D.astronomy
