石墨

In the light of the principle of electrochemistry , a series of experiments about the condition of GaAs films and AlGaAs films growth have been made by electrochemisuy deposition method .These experiments have been carried out with graphites as anode materials and conducting glass of tin dioxide ,stainless steel and aluminium foil of tin dioxide as cathode substrate materials in electrolyzers designed and made by ourselves and in the solution of compounded- simple sal.

根据电化学原理，采用电化学沉积方法，在自行设计及制作的电解装置中，以石墨作为阳极材料，SnO_2导电玻璃、不锈钢和SnO_2/Al 作为阴极衬底材料，在配制的简单盐溶液中，进行GaAs和AlGaAs 薄膜生长条件系列实验。

The first advantage is the rough and wrinkled surface texture of graphene, caused by a very high density of surface defects.

第一个就是石墨结构表面的粗糙和褶皱（由表面高密度的瑕疵导致）。

Based on the higher-order Cauchy-Born constitutive model, a seriers of infinitesimal mechanical properties and the strain energy for the graphite sheet and SWCNT are studied firstly with the consideration of the influences from tube chirality and radius, potential parameters and the inner displacement.

基于所发展的高阶Cauchy-Born广义连续体本构模型，首先对石墨片和单壁碳纳米管的一系列无限小变形的力学特性(如：轴向和环向模量、泊松比、剪切模量)以及应变能进行了研究，同时也考察了手性、半径、势能参数以及内位移放松等因素对这些力学特性的影响。

The complete set equipments of ball mill, crusher, magnetic separator, flotation machine, spiral sorting machine and dryer, etc are suitable in selecting black and non-ferrous metal such as iron, copper, gold, silver, lead, zinc tungsten, molybdenum, tin, manganese, etc and nonmetal mine such as fluorite and graphite. The sand and crushed stone detritus equipments like jaw breaker, counter-attack breaker, sand-maker, shaker, sand washer, conveyer, etc apply to constructions of airport, railroad, highway, common freeway and architectures of national large-size bridge, cross-harbor tunnel, land tunnel, new high-level building etc.

球磨机、破碎机、磁选机、浮选机、螺旋分级机、烘干机等成套选矿设备，适用于选铁、铜、金、银、铅、锌钨、钼、锡、锰等黑色、有色金属矿及萤石、石墨等非金属矿；颚式破碎机、反击式破碎机、制砂机、振动筛、洗砂机、输送机等砂石破碎设备适用于飞机场、铁路、高速公路、普通公路及国家大型桥梁、海底隧道、陆地隧道、新型高层楼房等建筑材料制造行业。

Due to the suppression of reverse water gas shift reaction by adding steam in feed gas, more CO〓 participated in and promoted CO〓 reforming of CH〓 reaction, higher catalytic activity and less carbon deposition were obtained. On the surface of used catalyst there were two kinds of carbon species deposited on catalyst, one was decomposed CH〓 fragment, and the another was graphiticlike carbon.

在反应后催化剂表面有两类碳物种，一类在250～350℃出现的少量α-碳，应主要是活性高的CH〓解离碎片，一类是在700℃附近出现的β-碳，应是导致催化剂失活的类石墨化碳。

Graphite is a carbon crystal, is a non-metallic materials, color silver gray, soft, metallic luster.

石墨是碳的结晶体，是一种非金属材料，色泽银灰，质软，有金属光泽。

The copper concentration on silicon surface was determined by GFAAS joint with one-drop sandwich etching method.

硅晶片表面污染的铜的浓度通过石墨炉原子吸收技术结合液滴夹心刻蚀的金属富集技术测得。

In addition, the deflection of workpiece using machine strategy of cutting from both sides were smaller than that of cutting from one side.

采用在线摄影的方法，观察记录了石墨薄壁件高速铣削的加工工件断裂过程。

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。
