Solar collectors for the selective absorption of high-coating the introduction of Germany technology into the market, this new type of titanium-based and quartz-blue coating, a one-time use of ionizing coating process, as opposed to the widespread use of The black chrome plating and black nickel coating, in terms of performance on an unparalleled advantage.

用于太阳能集热器的高选择性吸收体涂层引进德国技术进入市场，这种新型的基于钛基和石英的蓝色涂层，采用了一次性电离涂层工艺，相对于普遍使用的电镀黑铬和黑镍涂层来说，在性能上具有无可比拟的优势。

Secondly, the influences of pH value of buffer solutions on the dedolomitization of dolostone powders and the expansion of a reactive dolomitic limestone were investigated. A program was conducted to study the reaction and expansion of dolostone powders in compacts and pastes of cement, and that of dolomitic rocks with few clay and quartz in alkaline solutions and concrete.

第二部分研究了溶液pH值对白云岩粉料的去白云化反应速率及活性白云质灰岩膨胀速率的影响；分析了白云岩粉料在水泥压实体中、含很少粘土和石英的白云质岩石在碱溶液及混凝土中所发生的化学反应，并测定了伴随化学反应产生的膨胀。

It can be seen from the results that: water potential in quartz sand layer decreases with increasing thickness of the quartz sand layer under fixed sprinkling rate and increases with increasing sprinkling rate under fixed thickness of quartz sand layer; some of water above quartz sand layer flows down through the quartz sand layer and some flows down along edges of the quartz sand layer; some of water detoured the quartz sand layer flows into the region below the quartz sand layer closely along lower surface of the quartz sand layer.

实验结果表明：在喷水强度一定情况下，石英砂层中的水势随石英砂层厚度的增加而减小；在石英砂层厚度一定情况下，石英砂层中的水势随喷水强度的增加而增大；石英砂层上方的水部分通过石英砂层向下流动，部分绕过石英砂层向下流动；绕过石英砂层的水部分地紧贴石英砂层下表面向石英砂层下方的黄土中流动。

Using the advanced analysis technology, such as inclusion measuring temperature, calcite cement's electronic probe and isotope analysis, and the water-core reaction theory, the paper sets up the diagenefic model of coal measures strata, time-temperature model and pore evolutionary model, and provides the basis for seeking the high efficient reservoirs.
