论文部分内容阅读
读了刊登在“地质论评”22卷4期上的吴锡浩、钱方两同志的“川江徐家沱—金刚沱河段现代河床砾石粒度和形态变化的初步分析”一文后,感到文中在统计计算和其它方面有一些问题,现顺次列于下,以供讨论。 1.关于平均粒径d的计算及其与搬运距离S的关系方面,有三点可讨论之处。首先,由吴文表2推断,他们是据各测点砾石三轴的加权平均值按算式d=(a·b·c)~(1/3)直接算
After reading a paper published in Geological Review, Volume 22, Issue 4, “Commentary on the Grains and Grading of Modern Riverbed in the Chuanjiang Xujiatuo-Kongtuo Tuo River Section” by Comrade Qian Fangliang, There are some other issues that are listed below for discussion. 1. On the calculation of the average particle size d and its relationship with the handling distance S, there are three points to discuss. First, Wu Wen Table 2 is inferred that they are directly calculated according to the weighted mean value of gravel triaxiality at each measuring point according to the formula d = (a · b · c) ~ (1/3)
