The research results indicate that the heat - insulating property of back covered porous brick and its brick wall is better than kp1 porous brick . the compressive strength of the back covered porous brick masonry reaches the standard level . the elastic modulus of the masonry is equivalent to other porous brick masonry and higher than solid brick masonry 研究结果表明，盲孔多孔砖及其墙片的绝热性能优于kp1多孔砖；盲孔多孔砖砌体的抗压强度能够满足规范要求，弹性模量与其它多孔砖砌体相当，高于实心粘土砖的弹性模量。
The best heat - insulated method can be realized with multi - technique heat - insulation . the self - cleaning and heat - insulated building coating obtained in this paper can be used on the buildings and covering materials . it not only can protect the material , prolong its lifetime , but also has efficient self - cleaning function and heat - insulation property 本工作研制的涂料具有高效憎水、防污自清洁、隔热功能，可广泛用于建筑墙体及覆盖材料的表面，该涂料不仅能有效保护材料、延长使用寿命、保持表面洁净，还具有较好的隔热节能功能。
With environmental compatibility and sustainability becoming increasingly important issues in the construction industry , aac has emerged as the ultimate building material . its unique combination of superior strength , lightweight , heat - insulating and workability makes the construction process much more efficient , saving both time and labor costs 随着环境保护与可持续发展越来越成为当今建筑业的热点问题，加气混凝土砌块作为一种新型墙体材料应运而生，它特有的集高强、保温隔热、质量轻、可加工性强等一系列优点为一体的特点使得建筑过程更为有效、省时、省力，从而倍受建筑业的欢迎，被广泛用作多层、高层和加层建筑的墙体材料。
However , the extent of application and the full play of function is far from the level that aerated concrete should be used in building . especially in past , aerated concrete is just used to replace the solid clay brick as commom wall material . not enough attention is paid to . its another important and outstanding function of heat - insulate 但是加气混凝土在建筑中应用的程度和功能的发挥至今远未达到应有的水平,特别是在过去的应用中,加气混凝土制品仅仅简单地作为代替烧结实心粘土砖的一般墙体材料对待,而对于加气混凝土制品的另一个更为重要和突出的保温功能没有为人们充分认识、注意。
According to the main cause of the heat loss in the course of conveying and applying steam , the steam - piping system of southwest jiaotong university has been rebuilt by designing and installing pipe rightly , optimizing the heat - insulating material and its thickness , reasonably selecting drainage valve and reasonably reclaiming condensate , the steam exploitation efficiency has been improved 根据蒸汽输送、使用过程中热损失的主要原因，利用管道的正确设计与安装、优化的保温材料和厚度、疏水阀的合理选择及冷凝水的合理回收改造西南交大热力管网，提高了蒸汽的利用效率。
Dried at the temperature , the film has surface with convex and concave microstructure , its hydrophobicity and surface roughness can be improved evidently by adding the bead - forming agent . ( 3 ) the self - cleaning and heat - insulated building coating with excellent hydrophobic property and gas - permeability was preparaed by using the hydrophobic additive , modified sepiolite and modified expanded pearlite ( 3 )应用疏水添加剂、改性海泡石、膨胀珍珠岩能够制得自清洁隔热功能涂覆材料；制备的疏水添加剂和经提纯、疏水改性后的海泡石和膨胀珍珠岩，对乳胶涂料的流变性能、稳定性能以及涂膜的疏水性能、对比率和其他常规性能无不良影响。
