【摘要】 提出用计算机模拟取样对不同的取样量重复进行测试多次，统计其检测结果的标准偏差，作出标准偏差s对取样量m的拟合曲线，再计算最小取样量。设计的模式是一颗一颗地取样，这样不存在取样操作及测试过程带来的误差，操作是可行的，结果是可靠的。计算机运算速度快，参数转换方便，也可以取毫克甚至更低质量的样进行实验。只要有足够的岩矿鉴定的资料，可以模拟不同状态下的样品取样过程。更多还原

【Abstract】 A computer simulated sampling processes was proposed in this paper.With repeat tested of different sample mass, and calculated the standard deviations of these results obtained from these tests, a fitting curve of sample mass to standard deviations was formed.Base on the uncertainty of characteristic value and fitting equation, the minimum sample mass was determined.Without any other test steps, the sample was taken by one grain, the error was come from the heterogeneity of sample only, so the minimum sample mass determined was reliable.Moreover, computers were operated more quickly and convenient to alternate parameters, it was closer to reality of samples.更多还原
