The highly constant quality of basf dispersion and compatibility of external wall decorative surface and thermal insulation layer interface ensure the stability for the whole external wall thermal insulation and surface decoration system 巴斯夫乳液稳定的高品质和外墙饰面与保温层界面的相容性保证了整个外墙外保温饰面系统的稳定性。
An optimal design on the insulation layer thickness of buried oil pipeline for an oil production complex in daqing oilfield is made , and comparison and analysis are also made between optimal design result and actual measured result 对大庆采油五厂的一条埋地输油管道保温层厚度进行了优化设计，并将优化设计结果与运行现状的测试结果进行了对比分析。
Also the insulation layers are always ignored in the calculation and analyze of hydrogenerator . however even a thin insulation layer may have a significant temperature drop and this will have a direct effect on the machine design 同时，在大型水轮发电机温度场的计算和分析中，绝缘层常常被忽略，但在一个很薄的股线绝缘层上将会有一个显著的温度变化。
It is used for aging test for wire , cable , the sheath of rubber ( plastics and artificial leather ) and insulation layer , as well as the other high polymer materials under the specific pressure and temperature in the medium of oxygen and compressed air 本仪器适用于电线、电缆、橡胶（塑料、人造革）护套及绝缘层以及其它高分子材料在规定的压力和温度下，在氧气和压缩空气的介质中进行老化试验。
This paper calculates the thermal insulation thickness of the " steal sheated steal " directly buried steam pipe with air thermal insulation layer under the condition of different temperatures , and compares it with the system without air thermal insulation layer 摘要对不同介质温度条件下有空气保温层的“钢套钢”蒸汽直埋管保温结构厚度进行了数值计算，并将计算结果与无空气保温层的保温结构厚度进行了比较。
The distributions of interface charge in the bottom of trenches and electric field in insulation layer were studied for the novel structure . the influences of insulation layer thickness and trench width on breakdown voltage were analyzed and compared with analytical results 利用器件二维数值仿真软件medici ，详细研究局域电荷槽内的电荷分布和埋二氧化硅层的电场分布，以及埋二氧化硅厚度和槽宽对耐压的影响。
The study of the influence of heat insulation layer on the result of deicing or snow - melting illustrates that if the cost of making heat insulation layer is high and the price of the electricity is proper , the heat insulation layer can be abandoned 通过研究风力对融雪化冰效果的影响得出：当风力超过三级时，风对融雪化冰效果的影响不能忽略。通过分析隔热层的存在与否对融雪化冰效果的影响，提出了可以考虑不设隔热层的方案。
Al2o3 coating is provided not only as insulation layer to decouple electrically the liquid metal flow from the load - carrying wall in the sake of the decisive reduction of pressure drop , but also as a barrier to reduce tritium permeation into structure materials 为减少液态金属mhd压力损失，分析液态余属包层各种相关材料影响因素，在液态金属流动管道内壁加以al _ 2o _ 3绝缘涂层达到电学和热学性质上的绝缘，并起到相当好地氚壁垒效果。
