super low frequency meaning in Chinese

超低频

Super low frequency therapeutic apparatus
超低频治疗机
It is the first time to use the conventional espi system ( neither phase shifting nor carrier is used ) to continuously analyze the super low frequency vibration with high quantitative in the world
在火箭固体燃料动态力学特性研究中，时间序列法成功的给出了固体燃料的蠕变曲线和蠕变速率曲线，并且给出了其热变形和蠕变不同时刻的全场位移分布。
A lot of engineering applications are carried out using our proposed method in this paper , such as thermal deformation measurement of a car lamp , analysis of the super low frequency harmonic vibration of a piezoelectric ceramic , dynamic mechanical behavior analysis of the ballistite material and so on
在前面所提出的理论基础之上，本文对该方法在实际工程中的应用做出了大量的工作。本文利用时间序列法实现了汽车前灯配光镜的热变形检测、压电陶瓷片的超低频振动分析以及火箭固体燃料的动态力学特性研究。
