与heat barrier相关的网络例句 [注：此内容来源于网络，仅供参考]

They can not trap as much air as the wool yarns, and do not maintain an effective barrier against heat transfer.

它们不能够像羊毛的纱线一样储存那么多空气，因此不能保持一个有效的阻挡层以抵挡热量交换。

They may melt at relatively low temperatures and resolidify in the form of a foam, which serves as a barrier to heat transfer from the flame to the substrate

阻燃剂在相对较低的温度时会熔化，然后重新固化成泡沫状，这样就形成了一个屏障，阻止了从火焰向织物的热传递。

Flame retardants may interrupt or change the decomposition process in several ways:(1)they may melt at relatively low temperatures and resolidify in the form of a foam, which serves as a barrier to heat transfer from the flame to the substrate;(2) they may be converted upon heating into acids or bases, which catalyze the decomposition of the substrate at lower temperatures than are required for the formation of volatile combustibles;(3 ) they may decompose orsublime upon heating to release large amounts of nonflammable vapors which exclude oxygen from the flame; or (4) they may react with chemicakl species within the flame to stop the combustion reaction.

阻燃剂可以从几个方面干涉或改变织物的分解过程：（1）阻燃剂在相对较低的温度时会熔化，然后重新固化成泡沫状，这样就形成了一个屏障，阻止了从火焰向织物的热传递。（2）阻燃剂受热时会分解成酸或碱，这些酸或碱在低于可生成挥发性可燃物的温度下可以催化织物的分解。（3）阻燃剂在受热时会分解或升华，同时释放出大量不可燃气体，这就阻止了氧气对火焰的供应。（4）阻燃剂可以与火焰中的化学物质起反应，使燃烧反应终止。

With the development of manned space flight and aeronautics, the technical requirements for heat protection material and thermal barrier coating, etc., are increasingly enhanced.

随着载人航天及航空技术的发展，对航天器的防热材料和航空发动机的热障涂层等技术的要求日益增高。

First of all, the factors which influence the thermal barrier effect and the relationship between the factors and heat resistance were analyzed. Then, the paper gave the mathematical model of the effect of thermal conductivity, coating thickness, environment temperature difference, and heat exchange coefficient on thermal barrier effect.

研究主要内容如下：本文首先分析了隔热效果的几种影响因素以及它们与隔热效果之间的关系，推导出了包含热障涂层厚度、导热系数、环境温差和对流系数等在内的影响因素与隔热效果之间的数学模型。
