【摘要】 文章用重量法研究了不同浸水条件下导爆管的吸水规律及其对传爆可靠性的影响。热力学分析表明，导爆管的吸水量不但和浸水温度有关，而且和温度沿导爆管的分布有关。在较低的温度范围内，当浸水温度沿导爆管的分布不均匀且水温高于环境温度时，足够长时间的浸泡，便会使导爆管大量进水并产生拒爆。更多还原

【Abstract】 By weight method,the water absorption law and its effect on the propagation reliability of plastic nonel tube under different water dipping conditions were investigated in this paper.Thermodynamics analysis indicated that water absorption mass was relevant to both the water dipping temperature and the temperature distribution along the nonel tube.Among the range of lower temperature,when dipping temperature distribution was inconsistent and the water temperature was higher than ambient environment,plenty of water would enter the nonel tube and make them misfire if the dipping period was long enough.更多还原
