A series of seismographs are arranged with their direction of vibration along the generators of a cone with vertical axis.
一組地震儀的振動方向是與具有垂直軸的錐體拾震器方向一致的。Shock and vibration measurements - characteristics to be specified for seismic pick - ups
沖擊和振動測量.地震拾波器規定特性Specification for shock and vibration measurements : characteristics to be specified for seismic pick - ups
沖擊和振動測量規范:地震拾波器規定特性The system introduces 991 ultra - low frequency pick up, and takes the vibration signal as the simulation input of practical measurement, which makes the s ystem can measure the ultra - low frequency vibration of long, large, tall and flexible structures and the low frequency vibration of engineering and site
系統引入991型超低頻拾振器，將其拾取的振動信號作為本系統實際應用測試中模擬輸入，使系統可對長大高柔結構的超低頻振動和一般工程及場地的低頻振動進行測量。A medium frequency - small size vector hydrophone of co - vibrating type is wrapped with low density compound material and in shuck only one piezoelectric ceramic accelerator is used for each channel to measure the vector components of the underwater acoustic field
摘要中頻小型同振式矢量水聽器採用低密度復合材料作為矢量通道外殼、壓電加速度計作為內部振動傳感器，以拾取水下聲場中的矢量信息。However, the normal electromagnetism rate transducer which has the high inherent frequency of that between 5 - 30hz normally can not get the signal below 1 hz, therefore, it can not be used for inspecting same signal, which confines its applications in engineering project
然而，由於普通的電磁式速度傳感器，其固有頻率較高，一般都在5 - 30hz之間，很難拾取1hz以下的超低頻絕對振動信號，因此不能直接用來測量上述超低頻振動信號，制約了該類傳感器在工程中的應用。分享友人
