摘要
比较了18m跨度的平房仓实仓早籼谷-500Pa和-300Pa两种气密性检测方式的关系。发现半衰期采用-300Pa要严于-500Pa的评价要求。同时为获得气密性检测数据的稳定性和可比性,建议实仓检测气密性时,取整个粮堆正中心位置为检测点。
This article compares two air tightness test ways of -500Pa and -300Pa to early indica rice in 18 me-ters span warehouse , and seek the relationship between them , finally the half -life of -300Pa is found to be stricter than that of -500Pa .Meanwhile ,in order to ensure the stability and comparability of air tight-ness test data .It is suggested to set the test point at the very centre of the whole grain bulk in warehouse w hen testing the air tightness .
