摘　　要：以β晶型无规共聚聚丙烯(β-PPR)材料为研究对象,运用广角X射线衍射法(WAXD)测试其中的β晶含量。讨论了扫描速度、测试功率、接收狭缝以及试样放置方向等测试条件对结果的影响。结果表明,在较慢的扫描速度、较高的测试功率、适当的接收狭缝以及试样径向放置等条件下,测试结果相对可靠。Theβcrystal contents of polypropylene random copolymer withβcrystal(β-PPR)was measured by wide-angle X-ray diffraction(WAXD).The effect of scanning speed,test power,receiving slit and sample direction on the results were discussed.It was found that the results tested under slower scanning speed,higher test power and with radial placement of sample were relatively reliable.

关 键 词：β晶含量 扫描速度 测试功率
