石墨

The results indicate that the corrosion resistance of gray iron with A-graphite is the worst. As the structure of white iron is almost carbide, its corrosion resistance is superior to that of gray iron.

实验结果表明：含有A型石墨的灰口铸铁耐腐蚀性能最差；白口铸铁因为它的组织几乎都为碳化物，所以它的耐腐蚀性明显优于灰口铸铁。

在没有石墨碳源存在的情况下，以高温常压条件下制备的碳含量为4.33％的铁碳化合物为原料，在温度1700 K和压力5.5 GPa条件下，8分钟的合成时间得到了微米级尺寸的金刚石颗粒。

In cast iron adding a certain amount of ferrosilicon can used to prevent the formation of iron carbide and promote the precipitation of graphite. Therefore the production of ductile iron, ferrosilicon is an important Inoculant (to help precipitation of graphite) and Nodulizer.

在铸铁中加入一定量的硅铁能阻止铁中形成碳化物、促进石墨的析出和球化，因而在球墨铸铁生产中，硅铁是一种重要的孕育剂和球化剂。

For this process,the free-standing diamond thick films were dipped in a saturated iron chloride solution and dried in atmospheric ambient.

其工艺为：自支撑的金刚石厚膜浸入饱和的三氯化铁水溶液中，然后平放在大气环境中干燥，将处理过后的金刚石膜放入MPCVD装置中，先用氢等离子体将氯化铁还原成铁，然后在800℃左右的温度下，利用铁对金刚石的催石墨化作用及氢等离子体的刻蚀作用将其表面刻蚀。

Experment and investigation indicated that by means of inoculation treatment the type D graphite cast iron can be obtained in sand mold.

实验研究表明，用孕育处理的方法能在砂型中稳定地获得D型石墨铸铁。

The joinings of graphite,SIC ceramic and 3D-C f /SiC composites were obtained by using silicone resin as a precursor at 800-1400℃.Effects of the curing and pyrolysis process of SR,pyrolysis temperature,holding time and heating rate on the joining were especially studied.

由硅树脂作为先驱体，在高温（800-1400℃）转化陶瓷结合层对石墨、SiC陶瓷及3D- C f/ SiC复合材料进行了连接实验，着重探讨了硅树脂固化裂解过程、裂解温度、保温时间及升温速率对连接性能的影响。

Their morphologies were characterized with scanning electron microscopy, transmission electron m...

通过扫描电子显微镜、透射电子显微镜的观察，以及对产物的拉曼光谱分析发现，用本方法制备得到的碳纳米管形态良好，石墨化程度高。

Especially in making large cross-section ductile iron parts, the graphite of the casting center is often abnormal.

尤其是在浇铸大断面球墨铸铁件时，铸件中心的石墨经常出现变态。

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。
