leak tolerance

According to the water quality requirement of the drinking water source in Huainan City, the maximum permitted runoff from the dam-controlled branches was calculated under different in flow conditions form the upstream.

以淮河干流鲁台子—石头埠段为例,针对河段内淮南市饮用水源的水质要求,在不同的上游来水条件下,计算闸控支流污水的最大允许下泄量;预测污水团到达水源区的浓度。

First, we discuss allowed leakage of He-Ne laser pipe to air and Ne gas, then the question of the measurement of leakage by using cumulation method is pat forward.

本文讨论了He－Ne激光管对空气及对氦气的允许漏率，提出用累积法对激光管的无损检漏问题，并对其最小可检漏率及特征时间提出一些具体数据。
