平衡角 meaning in Chinese

angle of equilibrium
angle of trim
balance angle
equilibrium angle
neutral angle
trim angle

The main content is as below : the data of the blade surface is transferred to that of the corresponding forging blade surface by elongating the blade on the tip and on the root , expanding the surface of the blade , extending the blade on both sides , calculating the blance angle
主要工作内容如下：根据叶片零件的型面数据，通过叶尖、叶根型面延伸、叶身型面余量加放、进排气边余量加放、计算平衡角等处理，转化成锻件型面数据。
The changing procedure includes : extending of the blade on the tip , extending of the blade on the root , expanding of the surfaces of the blade , extending of the blade on both sides , calculating the balance angle , changing the coordinate system , changing the data on the consideration of the shrinking and the reflecting of the blade material , etc . a blade surface is bended and distorted in three dimensions
具体转化过程包括：叶尖型面延伸、叶根型面延伸、叶身型面余量加放、进排气边余量加放、平衡角的计算、考虑叶片的收缩和回弹、坐标转换等。完成了叶身实体造型。叶身型面是复杂三维弯扭曲面，造型上既有精度要求又有光顺性要求。
