So, we founded rice to express a space (remarks: Domain name investor is appellative the domain name is rice), such we are offerred offer a page accordingly, use very little space and low price, it is rice farming people create this small vacuum, implementation they are many of the domain name sell information, rice farming people also got costing very small price, had very substantial favourable service, such, we initiated rice to express a space

所以，我们创建了米表空间（备注：域名投资人通称域名为米），这样我们提供相应的出售页面，利用很小的空间和低廉的价格，为米农们创造这个小的空间，实现他们大量域名的出售信息，米农们也得到了花费很小代价，起到了很实惠的优惠服务，这样，我们开创了米表空间

It is the first time that no additional anode was adopted in the magnetic macroparticles filter. At the same time the auto-re-igniting system was designed for vacuum cathodic arc deposition instrument. It ignites the arc with an electronic component with high voltage and can auto distinguish weather the arc dies out or is on during the deposition via a main power supply feedback unit. The energy for igniting the arc is very less and thus can successfully prevent the film being contaminated.

设计制造的电子式真空阴极弧离子镀引弧器成功地实现了高压脉冲引弧，可以多次重复使用，所用能量较小，可以有效防止对所镀膜的污染，引弧可靠，能够自动识别电弧是否引燃，能够在熄弧后自动重新引弧，重新引弧的速度快，有效防止了熄弧引起的气压波动，使镀膜过程中气压非常稳定。
