"Olefins may be classified by whether the double Bond is in a ring or a chain or by the number of double Bonds (monoolefin, diolefin, etc.)."

有两种分类方法︰一、分为环烯烃和非环烯烃，双键依次位于成环碳原子之间或开链基团的碳原子之间。

At this stage, the solid pyrolyzed products of polysiloxane and polycarbosilane were amorphous silicon oxycarbide and nonstoichiometric silicon carbide containing excess carbon, respectively At higher temperature, structure of the amorphous pyrolyzed products started to rearrange and experienced a disorder →order transformation, even crystallized Cristobalite crystallized from SiO〓C〓, and β-SiC also crystallized from SiO〓C〓 provided carbon content of the starting polysiloxane was high enough, while β-SiC crystallized from SiC〓.

当热解温度达1000℃时，聚合物先驱体的无机化过程已基本完成，其陶瓷转化率值趋于稳定，此时聚硅氧烷的热解产物为非晶态的氧碳化硅，聚碳硅烷的热解产物则为含过量碳的非化学计量比的非晶态碳化硅；随着热解温度的升高，非晶态热解产物的结构逐步调整，发生无序→有序的相变，以至析晶。

However, with the increase of CNTs content, the carbon nanotubes might be aggregated, which made CNTs dispersion in the matrix uneven and the strength of the composites lower.

但是随着碳纳米管含量的继续增加，碳纳米管可能趋于团聚，在基体中的分散变得不均匀，反而会使复合材料的强度下降。

Carbon nanotubesare one kind of excellent renforcing nanomaterials to improve the properties of various polymer materials,while the critical issue is the dispersion of CNT in polymer matrix or solvents.

目前碳纳米管在高分子复合材料领域的研究十分活跃，通过添用碳纳米管改善纤维材料的力学和导电性能，具有很好的研究和应用价值。

Reduces a row of main object still is the developed country, regarding carbon and so on China collects the potential to be huge, the water cycle influence giant country, then must collect through the ecology protection construction increase carbon, and strengthens the water conservancy facility display water cycle repair climatic change the function.

减排的主要对象依然是发达国家，对于中国等碳汇潜力巨大、水循环影响力巨大的国家，则要通过生态保护建设增加碳汇，并加强水利建设发挥水循环修复气候变化的功能。

This method can be used not only in the preparation of ACEI medicine intermediates, but also as a kind of simple and important method in increasing dissymmetry carbon atom quantity and extending carbon chain.

本方法不但可以应用于ACEI类药物中间体的制备，而且是一种简单有效的增加不对称碳原子数量、延长碳链的重要方法。

It may result from the coupling of acarbonyl group in one molecule with the double bond in another molecule.

它是由一分子环丁烯二酮的羰基碳与另一分子的双键β-碳发生还原偶联的结果。

2"One-pot" carbon-carbon double bond formation.

2"一锅"法的碳-碳双键形成反应。

As used herein, an unsaturated hydrocarbon is defined as a hydrocarbon containing an isolated carbon-carbon double bond.

本文所使用的不饱和烃定义为含有一个孤立碳碳双键的烃。

Carbon is chemically versatile and is thus the body and soul of biological, geological, ecological and economic systems.

Springer2006碳和它的驯化碳化学多用途，并且是如此生物学，地质，生态和经济体制的身心。
