A new CNC (Computerized Numerical Control) controlled water-cutter system was constructed and an experimental study on the machining of natural rock materials by using this system was conducted. The system has many advantages, such as long available stand-off distance, low specific energy consumption, high cutting efficiency, low pump pressure, low cost, and long life-span of nozzle as well as convenient interactive manipulation. The water-cutter system can be widely used to machine various natural rock materials to any 2-dimentional curves, which are difficult or impossible to machine by using other traditional tools.

【期刊论文】A Method for Removal of CO from Exhaust Gas Using Pulsed Corona Discharge
李晓红, Xiaohong U, Lin Yang, Yuyong Lei, Jiansheng Wang, and Yiyu Lu

An experimental study of the oxidation of CO in exhaust gas from a motorcycle has been carried out using plasma chemical reactions in a pulsed corona discharge. In the process, some main parameters, such as the initial CO concentration, amplitude and frequency of pulses, resi-dence time, reactor volume, and relative humidity (RH), as well as their effects on CO removal characteristics, were investigated. O3, which is beneficial to reducing CO, was produced during CO removal. When the exhaust gas was at ambient temperature, more than 8O% CO removal ef-ficiency was realized at an initial concentration of 288 ppm in a suitable range of the parameters.
