The results show that catholic reduction of pyrolusite can be conducted, but the reduction rate is low. The effects of temperature to pyrolusite reduction on the cathode are remarkable. The exchange current density increases with the increase of temperature. The presence of irons is favorable to reduce pyrolusite.

Heat transfer between ingot and mold is then intensified by the quickened flow velocity of Al melt. As a result, the initial solidifying point on the ingot surface in mold moves upwards to decrease the height of contact zone between the melt and mold so as to improve the surface quality of ingot.

铝熔体流动速度的加快能增强石墨环与铝熔体之间的换热，使结晶器内铸锭表面初始凝壳点位置上移，减小了铝熔体与结晶器的有效接触高度，提高了铸锭的表面质量。

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.

The oxidation of diethyl stilbestrol was dependent on adsorption controlling process at MWNT /graphit modified electrode. The transmitted electron number, 2, was calculated by LAVIRON formula. By the linear relationship of peak potential and pH, it can be inferred that the transmitted number of electron and proton were equal.
