Graphite mold has been widely used in hot pressing of impregnated diamond hit manufacturing owing to its excellent performance.

石墨模具以其优良的性能被广泛应用于热压孕镶金刚石钻头的制造。

Carbon-doped TiO2 thin films were prepared by direct current reactive magnetron sputtering at room temperature in an Ar/O2 ambience, using a titanium target incrusted with graphite pieces. The films as prepared were characterized by X-ray diffraction, UV-Vis transmission spectra, and photoelectrochemistry methods.

室温下通过直流反应磁控溅射的方法，利用碳钛镶嵌靶在Ar/O2气氛中制备了碳掺杂纳米TiO2薄膜，并通过X射线衍射、UV-Vis透射光谱以及光电化学的方法对薄膜进行了表征。

The results show that SO〓〓 had been intercalated into the graphite layer structure during the electrolysis process.

By using a mean field approximation, the process of lthium intercalation into carbon materials was analyzed theoretically. GICs with less than 4 stage form when lithium intercalates into graphite by electrochemical methods. The capacity of lithium intercalating into carbon materials depends on the energy dispersion of lithium site in carbon.

通过平均场近似从理论角度分析了锂在石墨材料和碳素材料中的电化学插入过程，结果表明：锂插入到石墨中一般只形成4阶以下插层化合物，容量可达到LiC〓；而在碳中锂的插入量，根据锂可插入位置能量分布不同，一般小于锂在石墨中的插入量。

The results indicate that the relative atom content of Nd islow contrasted to that of Fe, which results from the weak competitive reaction ofNdCl〓 because of the strong bulk effects. The results of x ray photoelectronspectroscopy reveal that other valence of Fe could be in NdCl〓-FeCl〓-GIC.It is considered as the result of the charge shift between FeCl〓,〓 and graphitein intercalating process. Structural model of RECGIC was supplemented after thinking of the chargeshift between the intercalates and graphite. The characteristic layer distance, I〓, ofstage-1 RECGIC were calculated by the model.

利用能谱分析测定了NdCl〓-FeCl〓-GIC中插入剂的含量，结果表明， Nd的相对含量低于Fe的相对含量，这是因为NdCl〓的空间效应较大，而致使其竞争插入反应处于劣势的缘故。X光电子能谱研究表明，Fe可能有其它价态存在，这是由于在插入反应过程中，FeCl〓、NdCl〓以及石墨间发生电荷转移等作用的结果。

The ball milling and graphite blending process was used but the first charge/discharge efficiency is lower than that of without treatment. That means that the destroyed layer structure of MoS2 affects Li intercalating.

二硫化钼的可逆容量在661 mAh/g左右，对二硫化钼进行球磨、掺杂等改性处理，综合电化学性能反而有所降低，说明层片状结构的破坏影响了锂离子的嵌入。
