The whole point is to tune the primary and resonant capacitor until the circuit is critically damped (doesn't ring below zero), and turn on the mosfet just as the voltage reaches zero.

整个的一点是要调整小学和谐振电容器，直到电路极其阻尼，并打开的MOSFET正如电压达到零。

This wave direction may depend on the ratio of length to width of the structure. Therefore, it is necessary to make wave search to decide the most dangerous wave direction. In addition, the vertical displacement and wave bending moment of transverse section in long zero upcrossing period are larger than that in short zero upcrossing period.

另外，平均跨零周期较大时的垂向位移和横剖面波浪弯矩值大于平均跨零周期较小时的值，这时结构谐振峰值对响应的贡献不大，且垂向位移和横剖面弯矩沿浮体长度方向的分布呈现明显的非对称特性。
