GBW07390土壤標(biāo)準(zhǔn)物質(zhì),GSS-34土壤標(biāo)準(zhǔn)物質(zhì)取樣于天津市塘沽區(qū)于莊子村海河流域，70g/瓶， 有證書。
定值數(shù)據(jù)組數(shù)不少于 6 組、用準(zhǔn)確方法測試且精度良好者定為標(biāo)準(zhǔn)值；數(shù)據(jù)組數(shù)少（但不少于3 組）或精度不符合要求者為參考值，用帶括號數(shù)據(jù)表示。標(biāo)準(zhǔn)值不確定度（U）用公式計算，式中，uchar、ubb、us 分別為定值、均勻性和穩(wěn)定性引入的 不確定度，k 為包含因子，取 k=2。
