前言我处在解决山溪性河流測驗工作方面,过去曾試驗了几种溶液測流法,如硝酸銀,滴定分析确定流量法和电导滴定分析确定流量法等。由于这些方法,均在室內进行分析,始終未能得到全面的推广和使用。为了徹底解决山区河道积石壅塞,水势湍急,避免使用 Foreword I am dealing with mountain river test. In the past, I have tested several methods of solution flow measurement, such as silver nitrate, titration analysis to determine the flow method and conductivity titration analysis to determine the flow method. Because of these methods, they are all analyzed indoors and have not been fully promoted and used. In order to completely solve the problem of rock mass congestion in mountainous rivers, the water potential is in a hurry to avoid the use of
