For the heat conduct coefficient of casting nylon is much lower than metal , when making shaft lines , the wall should be as thin as possible 由于铸型尼的导热系数比金属小的多,所以做轴套时,壁厚应尽量薄一些。
It is widely used in the designing of heat exchanger , in the choice of the working medium of the thermal processing , it is the important gist 在换热器的设计、热力过程工作介质的选择中,导热系数是重要的设计与选择依据。
4 . the insulation layer selects material of low heat conduction and high temperature resistant , which decreases heat dissipation and ensures measuring accuracy 4保温层采用导热系数小耐温的材料,减少热源外散,保证测量精度。

The laboratory tests indicate that the heat conductivity of bentonite is correspondent to the charge of water content in bentonite 高庙子膨润土矿床初步确定为中国缓冲回填材料的供应基地,本研究通过实验,获得了高庙子膨润土的导热系数。
While successfully used in measuring the thermal properties of solid material , such as bulk samples and thin films , 3 method is seldom applied to the fluid 摘要3法已成功应用于体态、薄膜等材料导热系数的测量,但还很少应用于流体领域。
Results finally theoretically it concludes the rule that the change of the coefficient of thermal conductivity of the solid ' s surface follows the change of the temperature 结果理论推导出与实验事实相符的晶体表面导热系数随温度的变化规律。
Thermal conductivity of solid fuel , specific heat and curve of scaning hot method ( dsc ) under different temperture rate were acquired 进行了热物性参数试验研究,获得了固体燃料的导热系数、比热以及不同升温速率下的差示扫描量热法( dsc )曲线。
At the same time , the conductivity factor and the entropy of phase change of the solidation fatty alcohol were measured separately by using the time - temperature curve and dsc 同时利用时间-温度曲线法和dsc测定了固化十二醇的导热系数与相变焓。
