Foam insulation put on the hard concrete of the concrete jacket and shell structures to achieve the same with the purpose of life. At the same time, the wall surface with the decorative layer is to provide the same solid concrete foundation, decorative materials and the grass-roots level so that the thermal expansion material cold reduced the value of equal strength, thus ensuring the durability and the lack of maintenance of the quality. There is three-in-one insulation which is light body, set-load-bearing and warm kept at the same time.

把保温泡沫混凝土穿上坚硬的混凝土外衣与壳体达到了与建筑结构同寿命的目的，同时给墙体表面与装饰层提供了同样坚硬的混凝土基础，使饰面材料与基层材料的热胀冷缩值、强度基本相等，从而保证了耐久及无维修的质量，同时集承重、轻体、自保温三项功能于一身。

X 6 x 25 mm3 tested plates were cut from samples prepared from heating the PLLA powder at 220 oC under vacuum without pressure and gradually cooled from 220 oC until room temperature in a pot vented with nitrogen for one night. The crystallinity value of resultant samples was 43 %. These tested plates were implanted in the dorsal subcutis of S.D. rat after sterilization with ethylene oxide and removed at 1 d、3 d、7 d、21 d and 35 d intervals. These specimens were examined histologically with paraffin embedding section and resin embedding grounding section by light microscopy to evaluate tissue response. Three points bending test, viscosity and thermal properties were also examined.

这些研究对于提高热分析精度，具有重要的理论和实用价值。

This paper was concerned with the Dirichlet-Neumann mixed boundary value problem of bipolar quantum hydrodynamic model in thermal equilibrium. By truncation method and Leray-Schauder fixed point theorem, the existence of solution to the problem is proved. In addition, the uniqueness of the solution was proved as the Plank constant was large enough.

研究了热平衡状态下双极量子流体动力学模型的Dirichlet-Neumann混合边值问题，利用截断方法和Leray-Schauder不动点定理证明了其解的存在性，另外还证明了当普朗克常数充分大时其解是唯一的。

In this dissertation, the weak gels with good thermal stability and/or salt tolerance for use in EOR were prepared from HPAM and aluminium citrate or the compound containing hydroxymethyl groups in aqueous solution. The gelation mechanisms, structure, and properties of the HPAM-AlCA and HPAM-PRIM gels were investigated. For the HPAM-AlCA gelling system, the effects of aluminium : citrate and pH value on the properties of AlCA were systematically studied.

本文以研制高性能价格比的提高石油采收率用聚合物材料为目标，在耐温抗盐水溶性聚合物研究工作的基础上，选择聚合物弱凝胶这一前沿课题为研究对象，对HPAM-柠檬酸铝凝胶的有关基础问题进行了研究，研制出了具有优异耐温抗盐性能的HPAM-PRIM弱凝胶，解决了采用聚合物提高石油采收率的高性能与低成本之间的矛盾。
