此次偏差的可能原因是车间取样人员连续使用压盖器进行压盖，出现间歇性乏力

The possible reason for this deviation is that the workshop samplers continuously use the capping device for capping, and intermittent fatigue occurs, resulting in insufficient force during the capping process and insufficient capping, resulting in the aluminum cap not being compacted, under stable temperature conditions (40 ± 2 ℃), methanol is heated and volatilized, forming a certain pressure, the rubber plug is lifted up, and methanol gas slowly volatilizes from the gap of the rubber plug, which is an occasional case.

此次偏差的可能原因是车间取样人员连续使用压盖器进行压盖，出现间歇性乏力，导致在压盖过程中用力不足、压盖不够充分，导致铝盖未压紧，在稳定性温度条件(40±2℃)下，甲醇受热挥发，形成一定的压力，胶塞被顶起，甲醇气体从胶塞缝隙处缓慢挥发，属于偶发个例。

The possible cause of this deviation is that the sampling personnel in the workshop continuously use the capper to gland, which is intermittently weak, resulting in insufficient force and insufficient gland during the gland process, resulting in the aluminum cover not being pressed tightly. Under the stable temperature condition (40 ± 2 ℃), methanol is volatilized by heating, forming a certain pressure, the rubber plug is jacked up, and the methanol gas slowly volatilizes from the gap of the rubber plug, which belongs to a couple Make an example.<br>
