中文摘要: 本文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,做出标准偏差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,也可以取毫克甚至亚毫克样进行实验。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。
Abstract:A computer simulated sampling processes is proposed in this paper. With repeat tested of different sample masses, and calculated the standard deviations of these results obtained from these tests, a fitting curve of sample masses to standard deviations was formed. Base on the uncertainty of characteristic value, and fitting equation, the minimum sample mass was determined. Because the sample was took one grain by one grain, without any other test steps, the error was came from the heterogeneity of sample only, so the minimum sample mass determined was reliable. Moreover, computers operate more quickly and are convenient to alternate parameters, these made simulations are closer to reality of samples.
