Collapse angle

崩角───Collapse angle

In flight, the Angle of attack can only be adjusted to a small degree, as the wing is highly pliable and subject to collapse.───在飞行时，当伞翼变的极度容易折湾及崩溃时，攻角只能被调整至一个非常小的角度。

is a special way of design of carbon alloy slotting tool which has minus rake angle to increase the ability of resisting the tooth edge collapse.───为提高硬质合金插齿刀的抗崩刃能力，需要采用负前角的特殊设计；

variation law of the hole collapse pressure of extended reach well along with hole Angle and azimuth mostly decided by the status of the stratigraphic in-situ stress.───井井壁坍塌压力随井斜角与井斜方位角的变化规律主要由地层的原地应力状态决定。
