加速度衰减 meaning in Chinese

acceleration attenuation

First of all , it determines the scope in which earthquake might be genetated , the potential seismic sources areas and the upper limit of the earthquake magnitude through the analysis , research and evaluation of the area seismic geological condition of the workzone . secondly , according tothe research of the seismic activity , it also determines the seismic activity coefficients for per potential seismic sources areas , and the delay relation of seismic intensity and seismic accelaration , and then three different seismic intenstities and dynamic strength of bedroch under different probability are given . through the analysis and caculation of earthquake hazard with the analytic approach of probability
首先，对工作区的区域地震地质环境进行了分析、研究、评价，确定了莱芜市可能发生地震的范围、潜在震源及其震级上限等。其次，根据对地震活动性的认识，确定了各潜在震源区的地震活动性参数及莱芜市地震烈度和地震加速度衰减关系，在此基础上用概率分析法对莱芜市地震危险性进行了分析计算，得到了莱芜市在三种不同概率水平下的地震烈度和基岩地震动强度。
