But the Hymen that has a few woman is very withy, and springiness, although via making love for many times also not burst, it is Hymen aperture increases merely just, till somebody bears the Hymen when the first embryo to just appear burst, form Hymen mark, say so, sheet sees red or whether Hymen is complete after marriage anew will judge a female to whether have asexuality life history is not quite accurate also.

但有少数女性的处女膜非常柔韧，并富于弹性，虽经多次性交也不破裂，仅仅是处女膜孔增大而已，有人直至生育第一胎时处女膜才出现破裂，形成处女膜痕，所以说，单从新婚后是否见红或处女膜是否完整来判断一个女性是否有无性生活史也不够准确。

At the initial observation of leakage, judge on the leaking part of the foundation, and then manually set car observation, if the leakage were no significant changes in static and dynamic sealing ring has questions; such as disk when leakage can be concluded that there is significant change are moving , static friction ring problem exist; such as leakage of medium along the jet axis, the actin ring seal problem exist mostly, leakage to the surrounding medium or from the water spray cooling holes in the leakage, the many for the static seal ring failure.

在初步观察泄漏量、判断泄漏部位的基础上，再手动盘车观察，若泄漏量无明显变化则静、动环密封圈有问题；如盘车时泄漏量有明显变化则可断定是动、静环摩擦副存在问题；如泄漏介质沿轴向喷射，则动环密封圈存在问题居多，泄漏介质向四周喷射或从水冷却孔中漏出，则多为静环密封圈失效。
