But marine scientist Justin Ries of the University of North Carolina, Chapel Hill, hypothesized that not all ocean organisms would respond the same way to acidity because they use different forms of calcium carbonate for their shells.

北卡罗莱纳大学教堂山分校的海洋科学家贾斯廷·里斯提出一个假设：并不是所有的海洋生物对酸性表现出相同的反应，因为它们是利用不同类型的碳酸钙来作为外壳的。

The findings indicate that there are many micro-crannies developed in marlite, which can be seen under the Scanning Electron Microscope. The micro-crannies are the precondition of karstification process. Also, the calcium carbonate is dissolved through some chemical processes, and lots of mineral mud are carried away by mechanic erosion. The karstification process results in not only mineral component transformation, but also the rock mass structure alterations.

结果表明：微观下泥灰岩岩石中发育许多微小的裂隙，为溶蚀作用的进行提供了前提条件，另外泥灰岩中大量的泥质物随可溶岩的化学溶蚀过程发生了机械侵蚀作用：泥灰岩的溶蚀作用一方面引起矿物成分发生改变，另一方面导致岩石结构的变化。

At the optimum condition, which is at normal pressure and temperature 175-185 ℃, in mole ratio of phenol to DMC of 3:1, in 2 weight percent of catalyst to DMC, in 9ml/h of DMC feed rate and for reation period of about 12 hours, the yield of DPC is 23.5%, methyl phenyl carbonate yield is 47.89%, and the conversion of DMC is 82.4%. The reaction process was monitored and the reaction products were analyzied through gas chromatography and mass spectrograph.

The main raw material for producing magnesium carbonate and magnesium are magnesite, dolomite and bitten, which have abundant reserves in our country, especially the reserves of magnesite and dolomite, that not only holds the domain position but also has superior quality in the world, which establish the massy material developing foundation of magnesium industry.

但我们也应该看到虽然我国具有发展镁盐产品的优越条件，但因目前绝大部分现有生产厂家均属乡镇企业，资金有限，生产规模小，设备陈旧，技术力量薄弱，提高产量及质量的能力受到限制，且生产的品种单一，使我国镁盐的生产仍处于粗制初级、原料性产品的阶段，远不能满足国民经济发展的需要，高档、功能化产品仍需从国外进口，出口产品的价格只有进口产品价格的几分之一。

According to the space distribution characters of tectonic-sequence-based lithofacies and paleogeography, it is showed that three types of hydrocarbon source-rock including carbonate rock, clay and coal in Permian mainly are developed in transgression and maximal sea flooding of two order sequences, and they deposite respectively on platforms with gentle slope in craton, in rift basins and around old lands.

构造-层序岩相古地理的空间展布特征表明，二级层序的海侵期和最大海泛期是二叠纪烃源岩发育的主要时期，分别在克拉通的缓坡台地上、裂陷槽盆和古陆周缘形成了碳酸盐岩、泥质岩和煤系三类烃源岩。

The effects of emulsions, pigments, conventional fillers, heat-insulation fillers and film thickness on the reflection and heat-insulation properties under infrared lamp are investigated in order to find the best materials for the heat-insulation coatings. It is found that both the titanium dioxide with high refractive index and the diatomite powder with micro pores possess the optimal reflection and heat-insulation properties, calcium carbonate also has sonic heat-insulation effect. However, the filler such as meerschaum, which in theory possesses the effect, has not shown heat-insulation function.
