临界频率 meaning in Chinese
cf critical frequency
threshold frequency
Examples
- The critical frequency of the sinusoidal magnetic field increases with increasing magnetic field density
磁场强度越大，正弦磁场的临界频率越高。 - The electric field , magnetic field , critical frequency , surface current , power transmission and attenuation , as well as te and tm modes in waveguides are discussed
给出计算等效矩形截面波导的te模和tm模、电磁场、临界频率、波导壁电流、功率传输和衰减的公式。 - The dynamic character of the rotor system is the same as that without magnetic field when the magnetic field frequency is over a critical frequency , and the sinusoidal magnetic field cannot control the dynamic performance of the disk type mr fluid damper
当磁场的频率高于一个临界频率后，转子系统的动力特性与无磁场时的动力特性相同，正弦磁场不能够控制磁流变流体阻尼器的动力特性。 - Thirdly , considering when acoustic wave with a certain frequency or angle is incident upon plates , it will greatly cause the radiation power " translating . this paper details the causes of coincident effect and gets the calculating formula . the conclusion is resulted that thick plate and uniaxial anisotropies can lower critical frequency
针对声波入射板面时在某一特定频率或特定入射角度时会使声辐射能力大大增加并产生声能的大量透射这一现象，详细讨论了产生吻合效应的条件；并针对工程实际中所应用到的各种尺寸、材质的板分别推导了其吻合频率和临界频率的计算公式，得出了厚板和材料的各向异性均会使结构的临界频率下降的结论。
