石墨

Shown here are two allotropes of carbon: diamond and graphite.

这里展示的是两种碳的同素异形体：金刚石和石墨。

Just as pure carbon can come as diamond or graphite, boron comes in multiple forms - as many as 16 have been reported.

就像纯碳可以以钻石或者石墨的形式出现，硼也以多种多样的形式出现--据报道有已经发现16种形态。

Using diamond carbon source has greatly improved the synthesis efficiency.

此过程增加了石墨与金属接触的面积，也增加了碳的溶解量并降低了碳的浓度梯度。

In this thesis, we researched the process of transformation of carbon from graphite to diamond under HPHT in detail, proved the correctness of the mechanism based on TFD-C theory. This research settled the groundwork of improving method and technology of diamond synthesis.

本文从理论和实验上系统地研究了高温高压下石墨向金刚石转变的具体过程，验证了TFD-C理论提出的金刚石合成机理，为进一步改进金刚石的合成工艺和方法打下了一定的基础。

At present, industrial artificial diamond technic is a conversion of carbon from graphite structure to diamond structure by the effect of catalyst alloy at high temperature and high pressure.

目前，工业人造金刚石的合成是在高温高压条件下通过触媒作用将碳元素的排序由石墨结构转变成金刚石结构。

Experimental results showed that the Me_3C pattern carbides produced by the action of catalyst and graphite are main carbon source to form diamond structure under high temperature and high pressure.

在高温高压条件下，金属触媒与石墨形成的碳化物Me3C是形成金刚石结构的主要碳源。

The Edison 20 yearsold raise one's head start to study the electric lamp, the lasted morethan 10 years, he has successively selected the bamboo cotton andkapok, the graphite, the tantalum...... And so on over a thousandkind of different matter make the lamp silk material to carry on theexperiment, often passes 霄 until dawn, some he and assistantsunexpectedly continuous working 5 day and nights. In 1879 Edison withthe carbon silk took the incandescent lamp silk, and lights for 40hours.

爱迪生20岁出头开始研究电灯，历时10余年，他先后选用了竹棉、石墨、钽……等等上千种不同物质作灯丝材料进行试验，时常通霄达旦，有一次他和助手们竟连续工作5昼夜。1879年爱迪生用碳丝作为白炽灯丝，并点燃40小时。

In this paper several technologies, such as Fourier transform infrared spectroscopy, elemental analyzer, wide angle X-ray diffraction, field emission scanning electron microscopy, transmission electron microscopy and high resolution transmission electron microscopy were used to systemically investigate the evolution of crystal structure, chemical structure, microstructure and properties of wet-spinning and dry-jet wet-spinning PAN precursor fibers during proxidation and carbonization process, analysis the structural change of carbon fibers during graphitization, and discuss the correlation between the structure and properties.
