A comparative study of porosity, oxide contents, bond strength and wear resistance of 3Cr13 stainless steel coatings deposited by high velocity and regular arc spray processes was carried out. An orthogonal and rotational regression experimental method and an ordinary single-factor experimental method were adopted to evaluate the coating hardness with respect to the effect of processing parameters. The quantitative formula of processing parameters with coating hardness was obtained by means of microcomputer.

While this is being done, a supersonic nozzle injects a high-velocity gas jet in the area of the cut. The viscous molten material produced is then quickly stretched and cooled by the gas jet in a simple elongation process, to yield a disordered net of intertwined amorphous micro- and nano-fibres.

接著，以超音速喷嘴将高速气体注入熔融区，黏稠的熔融材料在简单的拉伸过程中藉由喷气快速冷却，产生一个非晶体微纳米纤维纠结成的网状结构。

But the siphonic roof outlet of system has complex hydraulic peculiaritys、 high velocity of flow and limited capability of dealing with overflow. The error of any design might cause the system invalid or to be insiphonic, furthermore, it can lead to drainage hitch or make big noise, and overflow will appear when the rainfall exceeds the design value of tube. So we should make further studies to consummate the hydraulic peculiarity and the method of calculation continuously.
