expanding coefficient meaning in English
膨胀系数
Examples
- Thermal expand coefficient of polyimide films at each temperature was measured in the process of thermal cycling
摘要测量了聚酰亚胺薄膜在冷热循环过程中各温度点的热膨胀系数。 - The results showe that the thermal expand coefficient of polyimide film is instability , it tends to stabilization after four times of psychro - thermal cycles
结果表明：聚酰亚胺薄膜的热膨胀系数具有不稳定性，当经四次冷热循环后才趋于稳定。 - As well , the compress stress existed in ( 002 ) crystal plane are found and can be explained by the matching between film material and substrate material as well as the different thermal expand coefficient between them
同时， zno薄膜( 002 )方向上存在着内应力，内应力是由膜材料与基底材料之间的晶格失配和不同热扩散系数造成的，退火可可使内应力的到不同程度的释放。 - In the process of preparing glass / mullite composite material , research on shrink rate , bending strength , dielectric constant , dielectric loss tangent , etc have been carried out . in the experiment , the thermal expand coefficient of samples is tested , and through sem , insides structure of sintered sample is studied , so the relationship of
在制备玻璃/莫来石复合材料的过程中，我们研究了烧成后径向收缩率、试样的抗弯强度、介电常数、介质损耗及其影响因素，并测试了试样的热膨胀系数，通过sem观测烧成试样的内部结构情况，找出性能和结构之间的关系。 - As the content of vermiculite minerals was about 3 % , the impact strength ( nick ) , the flexural strength and the heat distortion temperature ( hdt ) of the nanocomposites all were the lowest and decreased 21 % , 28 % , 3c , respectively . compared with those of the polybenzoxazine ( bisphenol a type ) , its thermal expanded coefficient ( tec ) was 3 . 4 % bigger than that of the polybenzoxazine ( bisphenol a type )
