1·During the drop, better have a lower speed of resitting and a smaller wrap Angle, which can have a smooth resitting without fierce impact.

在气门下降段，将气门的落座速度和下降段缓冲包角取小些，使得气门落座平稳，无激烈的冲击现象。

2·In varying wrap Angle flatness measurement system, the value of wrap Angle has a direct influence on the mechanics status of transducers.

在变包角板形测量系统中，无辊环式板形辊上传感器受力状态与包角大小有直接关系。

3·A zero-install roll Angle of the wrap around fins projectile still has roll moment at zero Angle of attack.

卷弧翼与弹身扣合较好，在零攻角下会产生滚转力矩。
