【摘要】 研究了输气管线冰阻附近的截面在输气管口从加压到稳定这段时间内压力变化的规律 ,给出了相应的压力变化曲线。得出了冰阻段的压力平方差曲线的斜率大于无冰阻段的压力平方差曲线斜率的结论 ,提出用应变测量的方法对输气管线同时进行两点或两点以上的测量来判断半阻位置。更多还原

【Abstract】 Discussed the variations of the pipeline pressure during the mouth of pipe being pressured,and got some curves.The results show that ice block pressure square difference slope of curve is bigger than that none,put forward with strain method to measure gas pipeline at two or more points to judge half resistance position at the same time.更多还原
