摘　　要：采用X射线正交透射法对聚丙烯腈碳纤维原丝的取向度进行测试,通过实验确定了取向度测定的最佳条件:X射线管管压40kV,管流30mA,方位角β以15°/min的速度从90°扫描到270°。该方法的相对标准偏差为0.06。In this assay, the orientation degree of the precursor of PAN carbon fiber is tested by X-ray orthogonal transmission method and the optimal conditions for the orientation degree test is confirmed through the experiment.The pressure of the X-ray pipe is 40 kV,the flow of the X-ray pipe is 30 mA. The azimuth angle β is scanned at the speed of 15°/min from 90° to 270°. The test results will be given by the data processing program of the computer. The relative standard deviation of the method is 0.06.
