Using established dynamics model, the author has explained the genesis of numerous dolichos lablab limestone and siliceous limestone in the two growing stages of southern China, i.e. carbonates developing stages (Donggangling stage of middle Devonian and Changxing stage of late Permian). Because numerous carbonate rocks have been produced on the platform, at the same time, it is one of ignored material sources that numerous carbonate lime-mud have been transported from platform to basin.

Fault zone is very clear in not only geophysical field but also seismic section, and it controls the development and distribution of sedimentary facies. On its downthrow, extension-depression basin develops, and on the upthrow, neritic carbonate platform or isolated carbonate platform develops, it is the structure--paleo-geography boundary of the two kinds.

There were many kinds of salinities industfall, and it was an approach of the salinity accumulation of soil.7.The content of organic compound in the dustfall in Tarim Basin were reduced from north to south,east to west. Dustfall was an approach that calcium carbonate and calcium sulphate to be increased, butthe content of calcium carbonate and calcium sulphate were different in each heights and sites.

降尘中含有多种盐分，是土壤积盐的一个途径。7 塔里木盆地降尘中的有机质含量由北至南、由东至西逐渐减小，降尘是碳酸钙、硫酸钙增加的一个途径，不同观测点及不同高度的降尘中的碳酸钙、硫酸钙的含量是不同的。

The process of diethyl carbonate synthesis by transesterification reaction of ethanol with ethylene carbonate,coproducing useful ethylene glycol was investigated using catalyst of sodium ethylate .

研究了以乙醇钠为均相催化剂，碳酸乙烯酯和乙醇酯交换合成碳酸二乙酯同时联产乙二醇的过程。

According to the results of thermodynamic calculations and the flyash-sodium carbonate sintering experiments, contrasting the energy consumption, material resource consumption and the expellant of the greenhouse gas CO2 during the two sintering processes, it demonstrates that the procedure could be the least consumptions of the mineral resources and energy, the least expellant of the greenhouse gas CO2, and that the terminal products with high value could be manufactured when sodium carbonate is taken as the flux agent.

基于热力学计算结果，对比了两种工艺的能耗、物耗、温室气体排放量等因素，结合粉煤灰－碳酸钠烧结反应实验，证明以碳酸钠为配料，高铝粉煤灰烧结过程具有一次性资源消耗量少，能耗最低，温室气体CO2排放量最小，且可生产高附加值产品，实现完全清洁生产等优点。

The 3×3 factorial design of adding calcium carbonate showed that PVA ratio at 30%, calcium carbonate ratio at 0.6% had an effect on the physical and mechanical properties.

添加碳酸钙的3×3复因子实验设计结果显示， PVA 添加比例应该可以维持在30%，添加碳酸钙的比例考虑维持在0.6%，对产品的物理性状及机械性状影响显著。

A schematic model was proposed to illustrate the occurrences of various lithologies and lithofacies associations. The erosional surfaces on siliciclastic mudstones, funnel-shaped structure, and the exhuming of massive cold-seep carbonates exposed might have been occurred concurrently during a tectonic unstable time in SW Taiwan. The deposition of fossiliferous mudstone interfingered with the conglomerate lithofacies, and represented the rapid facies transition from siliciclastic (non-carbonate) into carbonate environment.

综合岩相观察结果，建构一个符合台湾西南部更新世珊瑚礁与基底泥岩接触关系的沉积相模式；其中，基底泥岩顶部的不规则冲蚀面、充填碳酸盐胶结泥岩砾与碳酸岩烟柱的漏斗状沉积，以及块状冷泉碳酸盐岩的出露，可能均为区域地质构造活动时期所造成；至於与含化石泥岩同时沉积的砾岩相，可能均为基底泥岩在快速浅化的过程中所沉积，标志古环境由矽质碎屑快速转变为碳酸盐环境的过程。

Now, we specialize in the research, development and production of nonmetal superfine powder. Equipped with over 20 leading superfine powder production lines. we can yearly produce 300,000 tons of 60mesh to 7000mesh products including heavy calcium carbonate, surface treated calcium carbonate and French chalk, etc.
