The finite attenuationdistance 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。
2
Attenuation Coefficient The rate at which average power decreases with distance.
衰减系数平均功率随距离的延长而降低的比率。

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