During the last three decades, several models have been proposed to explain the formation of somites, including the clock and wavefront model, the reaction-diffusion type model, clock and induction model, clock and trail model etc. Although some of them are satisfactory in the different aspects of somitogenesis, no one can explain the formation and regulation of somites perfectly.

近三十年来，研究者们就体节的发生和发育提出了多种解释模型，这包括时钟波阵面模型，反应扩散模型，时钟诱导模型，时钟痕迹模型等，虽然这些模型能从不同角度不同程度来解释动物体节发生和发育的不同现象，但无一能够解释体节发生和发育的全部。

CO2 and H2S exist in the hydrocarbon zone and foramtion water,as the accompany gases of petroleum and nature gaso or components of formation water,which will cause corrostion to the cement sheath under certain conditions of humidity and pressure.It will decrease the cement sheath's alkalinity,which results in the decrease of cement sheath's strength,permeability increase,and places a premium on fluid channeling and borehole wall sloughs accident in plastic formation,shortening the oil- gas well's production lifetime and giving rise to tremendous ecomonic losses.

CO2和H2S作为石油和天然气的伴生气或地层水的组分存在于油气层或地层水中，在一定的湿度及压力条件下会对固井水泥环产生腐蚀作用，从而降低水泥环的碱性，使水泥环强度下降，渗透率增大，并诱发流体窜流、塑性地层井壁跨塌等事故，从而缩短油气井的生产寿命，造成巨大的经济损失。

In this thesis, nano-scale particles of metals, metal sulfides, selenides, oxides and nano-composites of metals/polymer, semiconductor sulfides/polymer have been successfully prepared by γ-ray irradiation technique in sorts of systems including water system, alcohol system, ethylenediamine system, microemulsion and emulsion system at room temperature and under ambient pressure. The possible formation mechanisms of nano-scale materials were suggested, and some factors of affecting the formation of nano-materials were studied.
