一、前言 在党的教育方针光辉照耀下,我们在去年参加了1/20万水文地质普查工作。生产实践使我们认识到了地下水简易化学分析在普查中的重要意义,因为最后成果的取得需通过整理和计算。但在大面积工作中,这工作是繁重的。除了容易发生差错外,如不能及时整理就不能在试验过程中发现问题及错误(例如Ca¨加Mg¨的毫克当量数大于cl′+SO″_4+HCO′_3的毫克当量数,这是不符合阴阳离子毫克当量均等的原理的)。
I. Introduction In the glorious shining of the Party’s education policy, we participated in the 1/20 million hydro-geological census last year. Production practice has made us realize the importance of simple chemical analysis of groundwater in the census, because the final result needs to be collected and calculated. However, in a large area of work, this work is burdensome. In addition to being prone to errors, problems and errors can not be detected during the test (eg, the number of milliequivalents of Ca- plus Mg- is greater than the number of milli-equivalents of cl + SO- 4 + HCO’_3, which is not In line with the principle of equal anion and cation milligrams equivalent).
