传统加速度仪加速度仪是用来记录当地强地震的仪器。1932年第一代USCGS型标准强震加速度仪开始布设在美国西部。在其后的30年间加速度仪的数量逐渐增加到大约60个台站。 50年代后期,作为一名大学生,我开始接触地震工程。尽管当时美国的台网很小,我们还是得到了关于Santa Barbara(1933)、El Centro (1934、1940)、Seattle(1949)、Kern County(1952)和大量其它地震的有用的加速度记录,促进了对强地面运动的振幅、频率成分和持续时 Traditional accelerometers are instruments used to record strong local earthquakes. In 1932, the first generation of USCGS-type standard strong earthquake accelerometer was deployed in the western United States. Over the next 30 years, the number of accelerometers gradually increased to approximately 60 stations. In the late 1950s, as a college student, I began to contact earthquake engineering. Although the U.S. network was small at the time, we still got useful acceleration records for Santa Barbara (1933), El Centro (1934, 1940), Seattle (1949), Kern County (1952), and numerous other earthquakes, which promoted The amplitude, frequency content, and duration of strong ground motion
