| 摘 要： | 本文研究了ＨＤＰＥ瓶装保鲜奶在二次灭菌过程中瓶内压的变化规律；通过模拟实验测定了ＨＤＰＥ瓶的变形量，建立了ＨＤＰＥ瓶变形量随温度及压力差变化的二元回归方程。在此基础上测试得到了ＨＤＰＥ瓶及其铝箔封口的的临界压力差。为乳品生产及研制国产保鲜奶设备提供了参考依据。

| Abstract: | his article studies on alteration rule of inside pressure of fresh milk during second sterilizing in HDPE bollte. By simulating experiment, the change of shape of HDPE bollte is observed and a two variable regression equation is set up, in which the change of shape of bottle depends on the variation of tempeature and pressure. Base on these, we measure the boundary pressure on the HDPE bottle and its aluminum seal. This offers a reference to the milk production and invention of equipment for keeping milk fresh. |

| Keywords: | pressure inside bottle pressure inside boiler chanced of shape boundary pressure variation |
