Determination of crystallinity and lattice parameters of synthetic molecular sieve by x - ray diffraction 射线衍射法测定分子筛晶胞参数与结晶度
Standard test method for determination of relative crystallinity of zeolite zsm - 5 by x - ray diffraction X射线绕射法测定沸石zsm - 5相对结晶度的标准试验方法
The effect of different heat treatment factor on pvc crystallinity was studied firstly in this paper 本文首先通过热处理研究了不同因素对pvc结晶度的影响。
The ideal heat treatment time was about 2 hours and the maximum crystallinity appeared at 130 掳 c 热处理时间在2h左右有较好的效果,而热处理温度在130左右出现最高结晶度。
The research result indicated that heat treatment time and heat treatment temperature had effect on pvc crystallinity 研究结果表明:热处理温度和热处理时间对pvc的结晶度都有一定的影响。
