tainter

And the results of the four field tests on the structural damping and natural frequencies of the tainter gates are introduced, which are necessary for judging the dynamic instability of the tainter gate and show that the structural damping of the barrage tainter gates is very small.

给出了判断动力失稳所必须的弧形闸门结构阻尼比的原型观测结果，它表明表孔弧形闸门的结构阻尼比是很小的。

Under the conditions of the large opening with lateral displacement at the juncture of the gate arm and the panel, the parameter resonance easily occurs for the high head tainter gates but not for the low head tainter gates with better seal.

大开度、支臂与面板联接处有侧向位移时，深孔弧形门容易引起参数共振，表孔弧形门不易形成参数共振；

In addition, some characteristics of the critical cavitation numbers of the slide valve are analysed and discussed in the paper, and comparisons of the cavitation characteristics between the slide valve and the reversed tainter valve are also made.

此外，本文还分析讨论了平面阀门临界空穴数变化的一些特性，以及它与反弧形阀门临界空穴数变化特性的一些区别和原因。
