强震观测资料包括强震动时程记录资料和宏观震害调查资料两大类，前者是定量的微观数据，后者则是定性的宏观指标。本文明晰给出了微观仪器烈度与宏观仪器烈度、微观考察烈度与宏观考察烈度的概念，并在此基础上提出了只有在宏观仪器烈度与宏观考察烈度之间进行比较才具有实质性的意义；同时对国内外常见的仪器烈度算法进行了比较性研究，得出了袁一凡仪器烈度算法可靠性更高的结论；最后以四川地区历年来重要震例的强震动记录为依据，对修正的袁一凡仪器烈度算法的可靠性进行了比较应用。结果表明，对袁一凡仪器烈度算法修正与扩展的应用是可行的，同时也验证了将微观仪器烈度与宏观考察烈度直接进行比较会存在较大的差距。

Strong motion observation data is classified into two categories,one is strong motion time history data,the other is seismic damage investigation data. The former is the microscopic quantitative data,and the latter is the macro-scopic qualitative indexes.Firstly we define the concept of microscopic instru-mental intensity and macroscopic instrumental intensity,microscopic inspection intensity and macroscopic inspection intensity in the present paper.And then we propose it is significant to compare macroscopic instrumental intensity with macroscopic inspection intensity.Meanwhile we also conduct a comparative study about the instrumental intensity algorithms at home and abroad.The results indicate that Yuan’s instrumental intensity algorithm is more reliable. In addition,based on the strong motion records of Sichuan earthquakes,the modified Yuan’s algorithm is applied to calculate seismic intensity.The results show that it is feasible to revise and expand the Yuan’s instrumental intensity algorithm,and also prove that there exists large difference when the micro-scopic instrumental intensity is compared with macroscopic inspection intensity directly.
