岩屑砂岩与岩屑石英砂岩中的高岭石晶间微孔是天然气的重要储集空间之一。

Intercrystal micropore in kaolinite is one of the important types of reservoir space of gas .

随着白榴石晶相含量的增加，长石瓷的断裂韧性也随之提高。

With the increase of the content of leucite crystals , the fracture toughness of feldspathic ceramics will increase accordingly .

高岭石的可交换性阳离子数量较少，Cd2+难以与高岭石晶层间的阳离子发生交换吸附，即主要以表面吸附为主。

Kaolinite has less exchangeability cations , Cd2 + was difficult into the crystal layer , which mainly by surface adsorption .

随着反应时间的延长，碳酸钙晶型由方解石晶型逐步变成方解石和球霰石组成的混合晶型，形貌也由类圆盘状的碳酸钙最终演变成球状碳酸钙。

With the reaction time prolonged , calcium carbonate polymorphs gradually changed from calcite to mixture of calcite and vaterite , and the morphology of crystal evolved from disc-shaped particle to spherical crystal .

储层储集空间类型以孔隙为主，孔隙主要为粒间孔、粒间残余孔、粒内溶孔和高岭石晶间孔。

The type of reservoir 's pore space is mainly pore , which can be subdivided into four sorts , i.e. , intergranular pore , residual intergranular , intragranular dissolved pore as well as Kaolin intercrystal pore .

薄片观察发现，实验后绿泥石晶须明显减少；浊沸石溶蚀强度有所增大，通过粒度分析也可看出，粒径Φ＞4的极细微粒及粘土质微粒明显减少。

Slice shows that after the experiment significantly whisker chlorite reduced , laumontite dissolution have increased , the particle size analysis shows that particle size Φ 4 of the very fine particles and clay particles decreased significantly . 4 .

金云母晶层和蛭石晶层结构破坏的温度点是不同的，前者在800～900℃之间，后者在900～1000℃之间。这为加工生产膨胀蛭石提供了重要的技术参数。

That the layer structure of the phlogopite layers and the vermiculite layers are broken down have different tempera-ture points in phlogopite ─ Vermiculite interstratification , The former is between 800 ─ 900 ℃ and the latter is between 900 ─ 1000 ℃ .

高岭石晶面是氢键联结，伊利石晶面之间是K~+离子联结，联结性较强，但因粘土矿物本身带有过量负电荷，也会吸附极性水分子而造成土质软化。

Crystal faces of kaolinite are combined by hydrogen bond and th'ose of illite are combined by K " 1 " ion . This kind of combination is relatively stronger but the soil will soften for the minerals have excessive negative charge , which lead to adsorption polar water molecule .
