| 摘 要： | 讨论了多相物质粉末衍射的物相检索问题，介绍了XRDS的物相检索软件。这是一种智能型的物相检索程序，考虑了测试数据的不确定度，以及粉末样品和块状样品衍射图谱各自的特点，不仅注意到实际样品中微量物相存在的可能，也注意到块状样品结构有序性的可能。XRDS能够帮助材料工作者同时检出样品中所含的多种物相及其含量，操作简单、结果可靠。

| Abstract: | The problems of phase identifying for powder diffraction of multiphase material have been discussed, and the software XRDS for phase identifying have been introduced. This is a intellect program for phase identifying, it considers the uncertainty of testing data, the diffraction characteristics of powder samples and block samples respectively. It also pay attention to the possible of a small amount phase existed in samples, and the possible of structure order existed block samples. XRDS can help checking the phases and their contents in samples, the procedure is simple, the result is reliabe. |
