一、问题的提出《赴南斯拉夫岩溶考察技术报告》中介绍了利用泉流量衰减曲线确定α衰减系数的方法,国内许多文献也利用此法计算了若干个实例。但由于α系数的物理意义未给予明确的揭示,因而难以深入理解泉衰减过程中所反映出来的水文地质特征。笔者在教学过程中,为了验证学生曾怀疑的在稳定流的条 First, the question raised “to Yugoslavia karst inspection technical report” describes the use of spring flow attenuation curve to determine the α attenuation coefficient method, many domestic literature also uses this method to calculate a number of examples. However, it is difficult to deeply understand the hydrogeological features reflected in the process of spring attenuation because the physical meaning of α coefficient is not clearly disclosed. The author in the teaching process, in order to verify the students had doubts in the stable flow of the article
