在这些剪切带扩张空间内，由于化学的、物理的及生物化学条件发生突变，导致热液的地球化学平衡被破坏，促使自然金沉淀析出，并聚集在剪切带内构成矿床。

Thermodynamics parameters show that the temperature in formation within 7 000~8 000 m of the basin is not so higher as decomposed temperature of pure calcic carbonate.

研究发现上覆层段的储集砂岩中含有丰富的菱铁矿(该矿具有低的热分解温度)，其能够与硅酸盐岩发生化学反应生成CO2，后者有可能成为气藏中CO2来源的一部分。

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。

In our previous work,we found that CDB underwent remarkable thermal decomposition at 90～120℃,which yields dithiobenzoic acid and related derivatives,it can affect the polymerization rate, molecular weight,and molecular weight distribution of the resulting polymers.

我们组发现一种常用的链转移剂CDB在加热情况下会发生热分解，分解产生的双硫酸会对RAFT过程产生一定的阻聚影响，同时使聚合部分不可控，即产物分子量不可控和分布变宽。

We understand that (1) releasing gases are mainly made up of CO 2 and alkane gases, and have a little ethylenic gases. There is a gas releasing peak at the temperature of 300～400℃ and the content of C 4～C 6 increases with temperature ri...
