Besides, the influences of different kinds of cathode blocks on the thermo-electric distribution in the lining were studied. The results showed that, with the increase of the content of graphite or the graphitized degree in the cathode blocks, the thermal gradient and voltage drop in the cathode decreased greatly; the liquidus isotherms moved toward the end wall and side wall in the vertical direction, but moved little in the firebricks.

此外，通过研究阴极炭块种类对内衬中电热场的影响，发现随着炭块石墨含量的增加，炭块的温度梯度、炭块中的电压降以及电解槽槽底电压降显著降低，电解质凝固等温线往槽大面和小面方向偏移，但在耐火砖内位置变化不大。

They were used as active material of anode materials for lithium ion batteries respectively, using constant-current cell tester to test their electrochemical properties.

近几年来，研究最广泛的锂离子电池负极材料是石墨以及各种碳材料，但研究表明，碳材料存在较大的能量损失和高倍率充放电性能差等缺点[2 ，3] 。

The catalyst for this reaction is iron chromium oxide with graphite as a binder.

进行这种反应的催化剂是以石墨为粘接剂的铁铬氧化物。

By the OM and SEM observation of solidification microstructure, the interfacial reaction between TiAl alloy and Al2O3 crucible was serious, and a large number of α-Al2O3 inclusion formed in the solidification microstructure. The interfacial reaction between TiAl alloy and ZrO2 crucible occurred only on the sample surface, but the crucible was not stable at high temperature and a tack coating was formed, clinging tightly with TiAl alloy. C element in the graphite crucible changed the original solidification path of TiAl alloy, and club-shaped γ-TiAl phases formed.

通过用光学显微镜和扫描电镜对凝固组织观察发现，TiAl合金与氧化铝坩埚之间的界面反应较为严重，在凝固组织中形成了大量氧化铝夹杂；TiAl合金与氧化锆坩埚的界面反应仅发生在试样表面，但该坩埚在高温下不稳定，并在试棒表面形成一层无法剥离的粘结层；石墨坩埚中的C元素改变了原有TiAl合金的凝固路径，生成了棒状的γ-TiAl相。
