ZnO, MgO and SiO_2 powders were covered on top of the alloy as dopants, the effects and principles of the dopants were discussed. Based these, SiC particles were made into preforms with different distribution of air holes by changing the granularity of SiC particles and the content of graphite additive, and the oxidation growth of aluminum alloy melt into the air holes within the preform was controlled to prepare SiC/Al_2O_3/Al composite with inerratic shape. And the SiC particles effect principle to the oxidation of SiC/Al2O3/Al composite was studied.

Here is an astounding fact: Neither the worker in the oil field nor the chemist nor the digger of graphite or clay nor any who mans or makes the ships or trains or trucks nor the one who runs the machine that does the knurling on my bit of metal nor the president of the company performs his singular task because he wants me.

这里有一个令人惊骇的事实：不是油田里的工人、不是化学家、不是石墨或者粘土的挖掘者、不是制造轮船、火车、卡车的人、不是运行机器为我身上铁片压花的人更不是铅笔公司的主席为得到我而执行单一的任务。

Here is an astounding fact: Neither the worker in the oil field nor the chemist nor the digger of graphite or clay nor any who mans or makes the ships or trains or trucks nor the one who runs the machine that does the knurling on my bit of metal nor the president of the company performs his singular task because he wants me.

这真是令人惊异的事：油田工人或化工师家，或石墨、粘土开采工，或者是制造轮船、火车、卡车的人，或者是操纵机器生产金属箍上的滚花的工人，或者是铅笔制造公司的总裁，所有这些人，都不是由于本人需要我而干自己的那份工作的。

The hydrogen precipitation of different metals, platinum, lead, nickel, iron and titanium, were discussed in different pH value and current density. By using Cyclic Voltammetry to study the reduction reaction, copper, titanium, lead, Ti/PbO2 and Ti/MnO2 as cathode respectively, it is proved that sodium metaborate can be electrochemically reduced to sodium borohydride. The kinetic parameters and fractal dimension of these electrode, graphite, lead iron Ti/PbO2 and Ti/MnOa etc, will be researched.
