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。

The main results and conclusions are as followings.1, The histone deacetylase inhibitors were used to feed the larve of the fly, and then the polytene chromosomes were observed under the microscope.

得到的主要结果和结论如下： 1，通过用去乙酰化酶抑制剂处理果蝇幼虫，观察果蝇多线染色体在热休克基因处的形态变化，发现去乙酰化酶抑制剂介导的乙酰化水平的升高可引起染色体结构的显著变化，推测乙酰化修饰不仅影响分子间的相互作用而且还可以影响染色体的高级结构。

Ore deposit, have been studied detailly; the orebody pattern (sedimental bedded ores combined with stringer ores of hydrothermal origin) is also outlined; four metallogenic epoches are devided; the zoning of mineralization (including zones of ores, elements, mineral assemblages and temperature of mineralization) have been depicted; the main types of wall-rock alteration are characterized as propylitization of basic rocks and pyritization-sericitization-silicification of acidic pyroclastic rocks; the origin of ores and seven kinds of main minerals have been studied; and the metamorphism and deformation of orebodies is thought mainly due to the shearing and the intrusion of subvolcanic rocks

研究了七个矿化带特别是I号矿床的矿床地质特征，描绘了矿体的双层结构(沉积矿石与热液充填交代的细网脉状矿石)，划分了四个成矿期次，区分了矿化分带(包括矿石组构的成因分带、元素分带、矿物组合分带、温度分带)，指出了围岩蚀变的主要特征是细碧岩青盘岩化而石英角斑质凝灰岩黄铁绢英岩化；对矿石及七种主要矿石矿物的成因作了研究；探讨了矿体的变质、变形，指出韧性剪切及次火山岩侵入的热力作用和应力作用是导致矿体变质变形的主要原因

The results show that thermoluminescent anomalies, whose two edges are higher and the middle is lower, indicate the uranium deposit, the rapidity step of natural voltage indicates the transitive section of oxidation-reduction.
