根据计算的各抗震设防烈度对应的地震作用及开裂荷载、屈服荷载设计出加载制度； 采用液压伺服装置进行低周反复荷载试验。
The loading process is designed on the basis of the cracking and yielding loads and earthquake action as calculated for seismic load of fortification intensity.
任何一个时期都具有不同程度的频度和烈度，从1941年到冷战这段时期最合适于用高频度，低烈度冲突来描述。
While any period can experience various degrees of frequency and amplitude, the period from 1914 through the end of the Cold War is best characterized as high-frequency, low-amplitude conflict.
