Because of the presence of carbon interface between the fibre and matrix, high real and imaginary parts of the permittivities of the composites are obtained.

由于碳界面层的形成，SiC/LAS材料要比LAS材料具有更高的介电常数和损耗。

The approximate calculating method is proposed for the low loss and thin flake material perturbation outside of the cavity. The measured complex permittivities of teflon,polyvinyl chloride ,pure ceramic flake are in good agreements with the standard data.

在隙缝辐射较小的条件下，提出适于损耗小，厚度薄(1mm左右)的片状材料腔外微扰的近似计算方法，测得聚四氟乙烯、聚氯乙烯、纯陶瓷片等复介电常数与准确值相当吻合的结果。

The samples have lower permittivities by adding MgO before Ba0.6Sr0.4TiO3 powder be pre-synthesized, but have higher tunabilities and lower high frequency losses by adding MgO after Ba0.6Sr0.4TiO3 powder be pre-synthesized. The tunabilities of the samples prepared by adding 15%~25% MgO after Ba0.6Sr0.4TiO3 powder be pre-synthesized are all higher than 20% at 103 V/mm.

MgO添加量相同时，在预合成BSTO前加入，样品的介电常数较低；在预合成BSTO后加入，样品的高频损耗较小，可调性较高，当添加质量分数为15%~25%的MgO，样品在10^3V/mm电场强度下的可调性均高于20%。

Because the length of optical fiber delay lines has direct effects on the volume of laser warning system, the optical loss and the false alarm ratio, the optical fiber delay lines are permuted and combined based on the property of the laser pulse and the optimization theory.

针对光纤延迟线的长度对激光告警器的体积，光学损耗，虚警率等因素有着直接的影响，在此利用激光脉冲的相关特性，通过最优化理论对光纤延迟线进行排列组合，从而解算出光纤总长度的最小值，为激光测向告警器优化设计提供了重要的理论依据。

The influences of matrix electrical conductivity on the poling behaviors were studied experimentally and theoretically.

从理论和实验两方面研究了基体电导率对极化行为以及介质损耗的影响。

Obviously, with such high temperatures, tyre degradation was more rapid, especially with the rears.

显然，这么高的温度，轮胎的损耗也更快，特别是后胎。

Our country railroad refrigerates the transportation profession infrastructure to be backward, the transportation wear-and-tear is big, and adjusts with difficulty, cannot satisfy now the market small batch, the multi-variety movement requirement, encounters the road to refrigerate transportation's huge challenge, if cannot according to the market development adjustment transport mode, very quick seize as soon as possible by the latter the market.

朋友们，帮我看看这个翻译该怎么修改唉句子很难搞得通顺，哪位朋友帮帮忙修改好不，急！例文：我国铁路冷藏运输行业基础设施落后，运输损耗大，且难以调节，不能满足现在市场小批量、多品种的运输要求，遭到公路冷藏运输的巨大挑战，如果不能够尽快根据市场发展调整运输方式，很快就会被后者占领市场。

And it saps energy and motivation.
