The entire dedendum should be round corner , to the gear of 200 pressure angle , the yield strength is largely improved than the 14 . 50 pressure angle gear 整个根都倒圆角压力角200的轮,其屈服强度比14 . 50压力角的轮得到极大
The main content of chapter ii describes the positive influence of rounded corners on keen vertexes of wide slot antennas and bowtie ones . a great deal of experiments and simulations prove the conclusion mentioned above 第二章主要讲述在宽槽天线( wideslotantenna )和多个蝴蝶结天线( bowtieantenna )辐射面的尖锐顶点处倒圆角对天线性能的改善作用。
This method rounding the keen vertexes on the plane antennas fits for not only wide slot antennas and bowtie antennas but many other plane ones . the method is not applied first in the thesis ; however , the foregoing papers did not do some summarizations on it 这种在天线尖锐顶点处倒圆角来改善天线性能的方法不仅仅适用于宽槽天线和蝴蝶结天线,对很多平面天线也是适用的,此论文并非第一个应用本方法的工作,但是前人并没有对此进行总结,本文总结的这一改善天线性能的方法得到多篇已发表的文献支持。
