常规剖面 meaning in Chinese

normal profile

This paper present an ideal and calculation method of the effective operating curve where cavitations characteristic is not change . based on the lifting - line and lifting - surface method , using effective operating curve to control the cavitation type and " new section " design method to extend the width of cavitation bucket . the width will almost increase 30 % than the common section
提出了保持剖面空泡特征不变的有效运转曲线的思想和确定方法，在升力线和升力面的基础上，应用有效运转曲线控制空泡类型，采用“新剖面”设计方法扩大空泡斗宽度，其空泡斗宽度比常规剖面增加近30左右。
