摘要
在各物相的质量吸收系数已知时，对一种新的无标定量相分析法（ＱＰＡＷＳ）作了探讨．在ＱＰＡＷＳ中应用了最小二乘法，文中提出了新的推导方法并得到新的表达式。
A new method for quantitative phase analysis without standards (QPAWS) is discussed on the basis of known mass absorption coefficient of each phase. The least-squares regression method has been used for QPAWS analysis. A new deduction and a new formula are presented in this paper. Experimental verification of the method with three-phases of artificial mixtures gave satisfactory results.
