本文仅讨论未老化状态下绝缘材料的软化。出于测试和讨论目的，密封环境分为三个主要元素；（1） 制冷剂（2）油（3）热。对制冷剂、油和热的影响同时进行了有限的定量成分软化试验；然而，在系统测试中，同时对三个环境要素的评估通常是在定性意义上完成的。引文:美国密歇根州底特律ASHRAE学报第85卷第2部分

This paper discusses softl:ning of insulating materials in an unaged state only. For testing and discussion purposes the hermetic environment is broken into three major elements; (1) refrigerant (2) oil (3) thermal. Some limited quantitative component softening testing has been conducted on the effects of refrigerant, oil and heat simultaneously; however, the evaluation of the three environmental elements simultaneously is generally accomplished in a qualitative sense under systems testing.
