1·The results indicate that the film pressure distribution is changed, and the performance parameters such as opening force, gas film stiffness, leakage are dramatically influenced by the face coning.

结果表明，锥度改变了端面膜压分布，并显著影响开启力、气膜刚度以及泄漏率等参数；

2·A theory model considering the face radial coning of spiral groove gas face seals was given.

提出一种考虑螺旋槽气体密封端面径向锥度的理论模型。

3·Coning can also occur by drawing down the gas-oil contact around a well.

围绕一口井下拉油气界面也会出现锥进。
