試样加工所用K值的試驗方法,在地質部所颁发的“地質勘探工作金屬矿产采样工作暫行规范”中所附的有兩种試驗方法。經詳加研究,发觉都有未尽妥善之处。茲就管見所及加以分析,并拟具新的試驗方法三种,以供大家研究討論。一、原試驗方法有缺点規范所附的K值試驗方法有兩种:第一种是采用Q=Kd~2公式中的d值不动,使Q起变化,决定了Q之后再計算出K的数值;第二种是Q相同,使用不同的K值(也就是不同的d值),將相同的試样进行縮分,用所得出的結果来比較而决定K值。这兩种試驗方法的基本精神是正确的,但在方法上就出了毛病,
Test methods used in the K value of the test method, issued by the Ministry of Geology, “Interim Provisions for Sampling Geological Exploration Metal Mining work,” attached to the two test methods. After careful study, I found that there are not perfect places. We hereby analyze and analyze the findings and propose three new test methods for discussion and discussion. First, the shortcomings of the original test method K-value attached to the test method there are two: The first is the use of Q = Kd ~ 2 d value of the formula does not move, so Q from the change, after determining the Q and then calculate K ; The second is the same Q, the use of different K values (that is, different d value), the same sample is reduced, with the results obtained to determine the value of K. The basic spirit of these two test methods is correct, but the method went wrong,
