| 摘 要： | 本文提出了利用所有可能利用的衍射数据求解低对称晶系(三斜、单斜、正交)晶胞参数的联立方程组法。测量误差会引起约10％数据偏离较大,但大量数据仍统计平均分布于真值附近。故采用一定程序的抛弃法可以得到较好的晶胞参数平均值结果。关键词：

| Abstract: | We present here a method of solving the simultaneous equations for obtaining lattice constants of low-symmetry crystal systems (triclinic, monoclinic and orthorhombic systems) by using all available diffraction data. Due to the measuring error, about 10 per cent of the data would show larger diviation. But most of the data are rather accurate and still distribute close to the true value statistically. Therefore, using a certain pro-grammed method for reasonable selection of data the best result of average values of lat-tice constant can be obtained. |
