摘要
以往的地面管道探堵法均依赖于管道内堵塞物发出的信号,事实上,堵塞物不发信号是不可避免的,研究不依赖堵塞物发信号的地面管道探堵技术具有重要的实际意义.用γ射线法对地面管道进行探堵研究,结果表明,通过测量γ射线的光子数,可方便地对地面管道实现探堵.
Previous methods for jam detection depend on the signals of the jam blocks in a pipeline. In fact, it is inevitable that jam blocks do not give any signal. Thus, it is of significance to study the method independent of signals. γ radiographic technology has been used to detect the jams of ground pipelines. Results show that jam detection can be carried out conveniently by measuring the photon number of γ-ray.
