The finite attenuation distance of the cylindrical and spherical detonation was deduced through analyzing the asymptotic attenuation.

通过对冲击波、爆轰波衰减渐近规律的分析，推导出柱面、球面强爆轰波的衰减有限距离的函数表达式。

Thirdly, on the base of "virtual distance attenuation", the paper brings forward a forecasting model of the CS of tourism websites—virtual distance weighing.

第三部分，首先根据旅游网站使用者满意度的“虚拟距离衰减”规律，引深提出了旅游网站使用者满意度的预测模式——“虚拟距离衡量法”。
