1·The result proved the seal's good leak tightness, stability, reliability and economical efficiency.

使用的结果证明说明该密封具有优良的密封性、稳定性、可靠性和经济性。

2·The building's outer Windows with a large heat transfer coefficient and a poor leak tightness are the key positions, where energy is consumed.

建筑外窗的传热系数大，气密性差，是建筑能耗的重点部位。

3·Flexible disc springs automatically provide leak tightness by exerting pressure, which keeps the upper and lower valve sealing rings compressed at all times.

柔性盘簧始终使上、下阀门密封环处于受压状态，自动密封防漏。

4·When an initial service leak test is permitted by the original code of construction, such testing may also be used to verify the leak tightness integrity of repair.

当设备一项初始试漏测试被原始建造规范允许，这项测试也可以用于核实设备的气密性泄漏的修理结果。

5·Selecting a suitable method of leak detection and measurement is the pledge to evaluate the tightness of systems and equipment correctly.

选用合适的检漏方法是正确评定系统和设备紧密性的前提。

6·Its good water tightness makes it leak free. Good mechanical performance enables the ceiling to cushion exterior impact and bear a weight as much as 100kg.

由于其良好的机械性能使天花能减缓外力冲击，承载100公斤以上的重量。
