一、切乔特法则列宁格勒矿业学院教授切乔特在综合试料加工实际经验的基础上得出结论说:试料之最小必要重量大致与最大颗粒直径的平方成比例。他后来把这一结论表示为方程式:Q=kd~2,式中 Q——试料之最小必要重量,公斤; First, Che Qiete law Leningrad Institute of Mining Professor Che Qiaotu based on the actual experience in the integrated sample processing concluded that: the minimum necessary weight of the sample is roughly proportional to the square of the maximum particle diameter. He later expressed this conclusion as an equation: Q = kd ~ 2, where Q - the minimum necessary weight of the sample, kg;
