spectral intensity 相对速度反应谱曲线在周期０．１ｓ与２．５ｓ之间所包围的面积。其值在总体上反映某一场地的地震震动强度，又称谱强度。
我国现行抗震设计规范中给出的反应谱依赖于两个参数，即地震烈度和场地土类别。
The response spectrum given by present design standards depends on two parameters, i. e. earthquake intensity and site classification.
第一种模型是在预测地震烈度和应用地震反应谱的基础上建立起来的；
The first kind of model is based on the prediction of the fuzzy earthquake intensity and the use of earthquake response spectrum.
最后还讨论了把设计地震反应谱转换成地震烈度的方法，给出了建议的转换方案。
Finally, a methodology converting response spectrum of design earthquake to seismic intensity is also discussed; and a conversion scheme is recommended.
