石墨

This paper deals with the preparation of synthetic diamond single crystal with boron at high temperature and high pressure from Fe-Ni-C-B system.

1前言石墨转变为金刚石是碳的同素异构体转变，由于触媒的参与使之合成压力与温度大幅度降低。

Evidence shows that small graphite flakes were formed and come off from the surface of the diamond powder.

此结果会使蒸发出来的蒸气中，金属与碳的比例在空间分布上更均匀，因而提高被石墨完整包裹GEM的良率。

Besides the organic functional groups absorbed on its surface, nanometer diamond powder contains a few graphite and SiO〓.

除表面吸附的有机官能团外，其主要杂质相为石墨和SiO〓。

The effect of boric acid on carbon fiber properties and thermal conductivity of carbon carbon composites was investigated by dipping preform in boric acid before pretreatment.

在预制体炭纤维预石墨化前对其进行硼酸处理，研究硼酸对炭纤维性能，C/C复合材料导热率的影响及其作用机理。

摘 要：在预制体炭纤维预石墨化前对其进行硼酸处理，研究硼酸对炭纤维性能，C/C复合材料导热率的影响及其作用机理。

For physisorption of organic molecules on chemically inert graphite, the interaction between the adsorbates and the substrate was very weak, which provided an opportunity to image the molecules with a minimum of substrate perturbation.

有机分子物理吸附在惰性基底石墨上时，分子和基底之间的相互作用很弱，吸附分子的STM图像反差主要由分子本身的性质决定。

Graphite and diamond are allotropes of carbon.

石墨和金刚石是碳的同素异性体。

In my eyes, diamond and graphite are allotropes of carbon with different constructions.

别以为有钻戒我就会答应你的求婚，在我眼里钻石和石墨均由碳组成，为同素异形体，只结构不同

Specially designed seals are used for all kinds of rotating equipment such as centrifugal compressors, autoclaves, filters, centrifuges, and mixers. In the same time, products like cyclone separators, coolers, entire sealing systems, packing, gaskets, magnetic couplings and so on are also produced.

并为所有旋转机械设备提供特殊设计的密封，如：离心式压缩机、高压釜、滤清器、离心机和搅拌器等，同时还生产用于密封系统的过滤器、分离器、冷却器以及填料、柔性石墨等静密封材料、伸缩节、磁力驱动联轴器等。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
