【摘要】 γ射线透射法测量输油管道油垢厚度,是一种无损检测的方法。利用 Monte-Carlo 方法模拟了这一过程,模拟计算结果与实验结果符合得较好, 进一步采用加权法进行模拟,改进了方差。得到了γ射线穿透率与管道中油垢厚度的响应关系,为生产中无损检测输油管道内油垢厚度,以及检测仪的研制提供了重要的参考依据。更多还原

【Abstract】 The calculation of the grease stain thickness which in petroleum pipeline was carried by the γ-ray transmission method which is unwasted. Using Monte-Calo method to simulate the program,which shows that it is fitable to simulate the experiment.And then using weighted method to improve the variance.The response ralationship between particle and grease stain thickness was found which can be based on the development of insturmentation and the using of the transmission method.更多还原
