检测频率 meaning in Chinese

i ectionfrequency/testfrequency
inspection frequency/ test frequency

However , this algorithm is not fit for the detection of the signals whose frequencies are very close to each other
但是该算法不适用于检测频率间隔很近的谐波和间谐波。
Lamb waves method is mainly used to characterize thin plate materials , without using very high frequency , it can measure the velocity of transverse wave and longitudinal wave , depth of the plate , and the bonding quality between plates
兰姆波法主要用于表征薄板类材料，无需较高检测频率，可以测得板中纵波和横波的声速、板厚和板与板之间的结合特性等，检测精度较高。
