    At the same time, this system displayed the calculating results of chromatism between this testing sample and other standard samples and the the reflectivity graphs.
    但是通过比较其色差计算结果发现待测样本y26与标准样本y2的色差值要大于其与标准样本y3的色差值,再观察反射率曲线图表明待测样本y26的反射率曲线与标准样本y3的反射率曲线更接近。 这就表明是实验前的肉眼分类有误,本系统的测试结果是正确的。

A procedure is established for the determination of multlphase components by X-ray diffraction through solving simultaneous equations. No standard samples are required in this technique. Major rock-forming minerals from thirteen granite samples have been determined and checked by planimeter and chemical analysis. The validity of this method is proved by the consistence among the results obtained by the three different approaches.

本文介绍了X射线衍射无标样解联立方程测定多元物相含量的方法和原理。用X射线衍射、求积仪、化学分析三种方法同时对十三个花岗岩样中的主要造岩矿物的含量进行了测定,结果比较一致。这证明用X射线衍射无标样的解联立方程法测定多元物相的含量是可行的。 由于以往的X射线定量分析需提取纯样作标样,但有些样品提纯相当困难,从而使X射线定量分析工作受到一定限制。本文采用无标样解联立方程的方法,仅在被测样品中加入合适的参考物质,测出各物相的参考常数K,便可测定各物相的重量百分数。正确测定花岗岩类的主要造岩矿物的含量,不仅能为花岗岩类的正确命名提供依据,而且对花岗岩的演化和成因的探讨也很有意义。以前这项繁杂的工作,主要用求积仪和化学分析的方法来进行,既费工又费时,其结果往往不理想。尤其是对斑状和细粒花岗岩,求积仪法难以测定,只能靠目估。为此,作者开展了用X射线衍射法测定花岗岩中主要造岩矿物含量的研究。通过对十三个花岗岩样的测试证明,用无标样解联立方程法,测定花岗岩中多种物相的含量是行之有效的。
