石墨

All common sulfide minerals except sphalerite are electric conductor s, so are most other minerals with a metallic luster, including graphite and some kind of coal.

除了闪锌矿外，其它的硫化物矿物都是电导体，具有金属光泽的大多数矿物也属导电体，包括石墨和某些种类的煤。

An arc-discharge facility was improved by adding two graphite plates to the electrodes to form a spherical cap capacitor in the vacuum cavity so that an additional electric field of appropriate intensity could be generated.

利用改进的电弧放电法，在真空放电室内分别安装两枚石墨极板，使之形成一个球冠型电容器。

The structure shown in the figure : The governing body received direct or roller drying cylinder, as the main components of the rotation; After finishing the outside of the sphere, Bottom Cover and soak spherical carbon graphite seal ring joint seal reliable seal friction deputy, Sealing ring in the spherical shell of its annular space sliding, in addition to oil-free bearings and with the close cooperation of Shell, Rotating connector so that the free support, and therefore do not require a high level of accuracy installed; Spherical seal ring wear, Spring means of pressure at any time in advance to receive compensation, compensation for the shell slowly moved backward, accessible through the tube outside the inscription on the line to observe the seals wear; When steam, Oil flows through the media or other spherical sealing ring and oil-free bearings, the formation of thin liquid film, sealing and lubrication, thereby reducing friction and wear, extending the service life.

其结构如图所示：外管体直接接到辊子或烘筒上，为主要的旋转部件；经过精加工的外管本球面、底盖和浸泡碳石墨球面密封环共同组成密封可靠的动密封磨擦副，球面密封环在其壳体内的环形空间中滑动，加之无油轴承与壳体的密切配合，使旋转接头自由支撑，故对装机精度要求不高；球面密封环磨损后，借助于弹簧的预压力随时得到补偿，补偿时壳体缓缓向后移动，并可通过外管体上的刻线观察到密封件的磨损程度；当蒸汽、油或其它介质流经球面密封环和无油轴承时，形成一层很薄的液膜，提供密封和润滑，从而减轻了摩擦和磨损，延长了使用寿命。

In Ductile Iron spheroidal nodules also eliminate the crack effect of flake graphite which is exhibited in cast iron.

球墨铸铁内部的球状结构也能够消除铸铁内部的薄片石墨容易产生的裂缝现象。

Morphology evolution and distribution of the graphite in spheroidal graphite cast iron were studied after repeated deformation in different directions at (800±10)℃ and (900±10)℃ with single reduction of 60% or 30%.

研究了球墨铸铁在(800±10)℃、(900±10)℃，单次变形量60%、30%的条件下，经不同方向多次压缩后石墨的形态变化和分布情况。

For cast iron with spheroidal graphite, the manufacturing processes shall ensure

3对于球墨铸铁，加工工艺必须保证90%的球形V 石墨和90%的球形VI 互相分离。为测

For structures and components in accordance with Chapters 6 and 7, cast iron with either spheroidal graphite according to EN 1563:2003 or lamellar graphite according to EN 1561:1997 may be used, depending on the mechanical properties required.

1第六章、第七章中的结构和部件，可以使用依据EN 1563：2003的球墨铸铁或者依据EN 1561：1997的层状石墨铸铁。

The successive growth system must be maintained at a stationary state by outer energy input.

在这种特殊的条件下，石墨生成金刚石是可行的。

Designed by Ned Steinberger, the Synapse bass guitar is a HYBRID instrument combining the strength, rigidity and clarity of graphite with the warmth and beauty of wood.

由内德斯坦伯格，Synapse的贝司吉他的设计是一种混合型的工具结合强度，刚度和的温馨和美丽的石墨木材清晰。

Solve this problem, the best way is to turn valve stem with a tour, or rotary type control valve, and its thick stem stroke than a straight stem 2 to 3 times, and use long life of the graphite packing, valve stem stiffness Good, filling long life, but its friction torque is small, poor little back.

解决这个问题，最好的办法就是用旅转阀阀杆，即角行程类的调节阀，它的阀杆比直行程阀杆粗2～3倍，且选用寿命长的石墨填料，阀杆刚度好，填料寿命长，其摩擦力矩反而小、回差小。

Recall that, in the Kolmogorov axiomatization, measurable sets are the sets which have a probability or, in other words, the sets corresponding to yes/no questions that have a probabilistic answer.

延期开工的Kolmogorov宣布要衡量所有套职能有限许多坐标限制在于衡量子寅。换句话说，如果是/否的问题回答f可看的价值观念在许多最有限坐标，然后它有一个概率的答案。

The experimental results showed that the algorithm can filter singular points and remain fixity of the target edge.

实验表明：基于模糊理论的图像智能滤波方法比常规图像滤波方法运算量小，它既能去除奇异点，又能保持图像中目标的边缘不变性，具有很好的滤波效果。
