没好气的

The analysis of thermal behavior and chemical structure show that the three main reactions do not initiate simultaneously. Dehydrogenization and cyclization reactions begin at the initial stage of stabilization, while oxidation reaction takes place on the precondition of cyclization reaction. Cyclization reaction has induction period that is influenced by temperature and heating rate.

热分析和化学结构分析的结果表明，预氧化过程中的三大主要反应并非同时进行，脱氢反应和环化反应从预氧化初期开始，而氧化反应需要以环化反应为前提条件，随后进行；环化反应具有一定的诱导期；在氧化性气氛中，首先发生脱氢反应，氧对环化反应起到了阻碍作用，使整个过程顺利可控。

First the varia bility must be measured, then understood before management becomes practical.

首先，要对这些变化因素进行度量，然后，对它们加以研究理解，以便应用到实际管理中去。
