冰花密度和渗透系數的測驗是冰期水文測驗工作中的新項目。今年2月7日我在蘭州水力發电勘测处見到了苏联專家關于冰花密度及冰花滲透系數測法的介紹,随后即進行了試驗。所謂渗透系數(或譯为过濾系數),是指冰花滲透速度而言。为了提供大家進一步試驗研究的参考,茲將該项測法和我們試驗的情形分述如下: 一、冰花密度的測法:在較大的量杯中,以溫度很低的煤油(溫度等于或低于冰花的温度),量其体 The test of ice density and permeability coefficient is a new project in the ice age hydrological test. February 7 this year, I met at Lanzhou Hydropower Survey Department Soviet experts on ice density and ice penetration coefficient of introduction, and then conducted a test. The so-called permeability coefficient (or translated as filter coefficient), refers to the speed of ice penetration in terms of. In order to provide a reference for further experimental research, the test method and our test situation are as follows: First, the ice density measurement: In a larger measuring cup, the low temperature kerosene (temperature equal to or lower Yu Binghua temperature), the amount of its body
