摘　　要：对于地质粉末样品,"内标法"所测结果是原矿样加入内标以后的混合物中分析元素与内标元素的浓度比。不是分析元素在原始矿样中的浓度。故,结果不能采用。用矿样作标准,不加内标,可以得到原始矿样中分析元素的准确浓度。所以,要用矿样标准法。In geologic powdered sample measurement,the result by＂the inside standard method＂ is the relative concentration ratio of analytic element inside standard element in mixture with element in the original ore sample,other than concentration of analytic element in prime ore sample.The result is not reliable.If the standard sample is chosen from ore sample,accurate concentration of analytic element in prime ore sample can be obtained.
