Water-based architectural heat insulation coatings were studied to overcome the drawbacks of conventional inorganic silicate heat insulation coatings.The heat insulation coatings were prepared with the method of mechanical agitation when the mixed organic polymer emulsions were used as binder of the coatings and the mixed heat insulating aggregates were applied as powder,and some assistants were also added.Water temperature difference in the plastic container,which was coated with heat insulation coatings,represented the heat-insulating property of the coatings.The influences of components of mixed polymer emulsion,mass ratio of polymer emulsion to powder,particle size of heat insulating aggregates,added amount of air entraining admixture and the match of thickeners on the properties of the coatings were studied.The experimental results show that the heat insulation coatings with good finishing,heat-insulation property and artificial weathering can be prepared when the binder is composed of 66.92% styrene-acrylic emulsion,16.59% elastic emulsion and 16.49% silicone-acrylic emulsion,the mass ratio of polymer emulsion to powder is 0.45,the particle size of heat insulating aggregates is in the rang of 200 and 250 mesh size,the added amount of sericite is 15%,and the added amount of air entraining admixture is in the range of 1.0% and 1.5% and the thickeners are the mixtures of ASE-60 and RM-5000.

尿酸是嘌呤化合物代谢的终末产物,嘌呤代谢紊乱可致尿酸水平升高而产生高尿酸血症.临床研究证实,高尿酸血症与糖尿病、高血压以及高脂血症之间存在着紧密相关性,并可诱发炎性反应,加重血管内皮损伤,最终加速冠心病和肾脏损伤的进展[1-3].现已发现多种转运蛋白参与了肾脏近曲小管对尿酸盐的转运过程.包括尿酸重吸收蛋白:尿酸盐阴离子转运体1 (urate anion transporter 1,URAT1),有
在GNSS高精度数据处理中,卫星钟差往往是决定结果精度的核心因素之一。采用20 Hz的双频观测数据对GNSS星载原子钟0.05~100s平滑时间下的短期稳定性进行分析,通过星间单差的方法消除接收机钟差,采用无电离层组合及夜间观测避免电离层高阶项短期变化的影响,同时采用经验模型和映射函数来进行对流层延迟改正。通过Lag 1自相关函数分析了影响GNSS卫星钟稳定性的主要噪声类型,并使用阿伦方差计算分析
