nodal plane meaning in English

波节平面
振动节面

The normal levitation of nodal plane tested under ultrasonic dynamic contact action validates the normal dynamic contact model
用微位移测试仪实际测试夹心式换能器节面沿纵向上浮的实验证实了该模型的分析结论。
The source time function directivity is in accordance with the p waveform directivity , clearly showing that the nodal plane of strike 199 is the fault plane and that the earthquake ruptured unilaterally from the northeast to the southwest
震源时间函数的这种方向性效应与p波的方向性效应相一致，清楚地表明：走向为199的节面为断层面，地震是从东北向西南方向单侧破裂的。
The ultrasonic dynamic contact of bolt - clamped transducer and rigid plane are modeled using hertzian contact theory , and the analyzing results reveal that the nodal plane of the bolt - clamped transducer is levitated in normal direction by the ultrasonic dynamic contact action , and the real area of contact of bolt - clamped transducer and rigid plane decreases in the same time
首先利用赫兹接触理论建立了夹心式换能器和刚性平面的超声动态接触模型。通过对模型进行分析、求解表明,在纵向超声频率动态接触作用下,换能器节面位置产生了上浮,换能器端面与刚性平面的动态真实接触面积比静态时减少了。
