济阳坳陷在古近系沙河街组沉积期属于古季风气候带，在湿热的气候条件下古湖水加深，分层性增强，浮游生物的古生产力降低，隐晶碳酸盐的沉淀速率变小，粘土沉积速率加快，还原性一定程度上有所加强，有利于黑页岩、油页岩和暗色泥岩的形成：而相对干冷气候下，古湖水变浅，分层性减弱，浮游生物的古生产力增高，隐晶碳酸盐的沉积速率变大，粘土的沉积速率减慢，有利于钙质页岩、钙质纹层页岩、钙质泥岩、泥灰岩甚至纹层状碳酸盐岩、灰岩的发育。

Environmental issue has caused widely public concern. In this thesis, the mechanism of calcite cluster structure absorbing environmental infectant has been investigated using quantum chemistry calculation. Using B3LYP calculation method and taking 6-311++G (3df,2pd) basis set in our Gaussian calculations, the results show that the calcite cluster structure can absorb environmental infectant.

The authors have summarized relevant data studied by overseas scientists and suggested the definition of chalky texture formation as "Chalky texture formation refers to that magnesium calcite and aragonite are transformed into the framework of micrite and microspar of low-magnesium calcite via neomorphism, and result in and maintain intercrystalline pore and throat networks in it; enhanced chalky texture formation refers to that the micrite and microspar are successively subjected to dissolution and leaching, so that the secondary network of solution voids is formed".

综合各国学者的有关研究资料，建议将白垩状结构化定义为：&碳酸盐沉积物和碳酸盐岩中的镁方解石和文石在不同成岩阶段通过新生变形而转变成低镁方解石微晶和微亮晶格架，并在其中产生和保存晶间孔喉网络的作用；强化白垩状结构化是指微晶和微亮晶格架受到进一步溶蚀和淋滤，从而形成次生溶蚀孔隙网络的作用&。

The paper expatiated the physical characters and mechanical performances of the composite material slabs synthesized by one, two, three or four minerals namely mica, mica + calcite, mica+ pyrophyllite + calcite or mica + calcite + pyrophyllite + periclase. It is concluded that the quality of the composite material consist of multiple minerals is better than the single material.

因此 ，国内外常利用金属纤维、有机增强纤维(碳纤维、木质素纤维、聚丙烯纤维)和无机矿物(玻璃纤维、岩棉、海泡石纤维、硅灰石纤维)来替代石棉材料，用于生产摩擦材料和高档保温材料 [1-2 ]。

A soft, pure, earthy, fine-textured, usually white to light gray or buff limestone of marine origin, consisting almost wholly (90-99%) of calcite, formed mainly by shallowwater accumulation of calcareous tests of floating microorganisms and of comminuted remains of calcareous algae (such as cocoliths and rhabdoliths), set in a structureless matrix of very finely crystalline calcite.

中文解释=海产起源的石灰石，柔软、纯净、土质、组织精细，通常从白色到浅灰或浅黄色，几乎完全（90-99％）由方解石组成，主要由浮游微生物的粉碎残留物浅水堆积而成，嵌在非常精细的方解石晶体的无定形填质中。

Two dominate variation trends are distinguished in the data plots of compressional-wave velocity versus Possion ratio, indicating the effects of mud content and calcite cement on the elastic properties of sandstone samples. In each change trend, with the rock texture transfering gradually from grain-supporting to matrix-supporting with increasing mud and calcite cement content, the propagation of elastic wave also changed from grain-to-grain contacts to rock matrix, which resulted in the measured data illustrating extremely different tendency. It helps utilize the physics properties of reservoir sandstone to extract rock texture and diagenesis properties in the research area.

样品在纵波速度－泊松比交汇图中表现出两种主要变化趋势，分别对应泥质与钙质胶结物的影响；在每个变化趋势中随泥质含量与钙质胶结物含量的增加，岩石结构从颗粒所构成的骨架支撑逐渐表现为基质支撑，弹性波能量的传播也从通过颗粒接触边界转变为通过岩石基质传播，这是使砂岩样品测试结果表现出两种截然不同变化趋势的主要原因，为利用岩石物理特性从地震资料中提取岩石结构、沉积与成岩特征的信息提供了依据。
