射气系数α与射气化系数η本质不同,从概念到命题都应把它们严格区分开来。指出现在η测定方法中,以铁皮作为覆盖材料存在的问题。介绍了以沥青作为覆盖材料所表现的多方面优点。
The arcing coefficient α is essentially different from the arcing coefficient η, and should be strictly distinguished from the concept to the proposition. It is pointed out that in the current measurement method, there is a problem that the iron sheet is used as the covering material. The multi-faceted advantages of using asphalt as a covering material are presented.
