| 摘 要： | <正> 过去在进行计算分峰时,不同相态的X-射线衍射峰形是用不同的表征函数来描述的。其中晶相峰多采用Hindeleh的对称复合函数;非晶相峰的表征函数则有多种形式。以后提出综合函数实现了两种相态表征函数的统一。在应用中发现,这一综合函

| Abstract: | Two new expression functions for the X-ray diffraction profile of both crystalline and amorphous polyphenylene sulfide (PPS) have been proposed:andwhere X is the diffraction angle, Y the diffraction intensity at X, W1,W2 the left width and right width at half height, P the maximum position, A the peak height, and / the shape factor. 5=sinθ/λ,(λ is the wave length of X-ray). Function (1) is suitable for the profiles plotted against diffraction angle X, while function (2) is suitable for the profiles plotted against S. The limitation to the range of applicable diffraction angle, which is inherent to the old expression functions reported in literatures, has been eliminated in these two functions. |
