接触荷电水雾除尘装置中的连续供水系统

论述了在接触荷电水雾除尘装置中采用双水箱串联供水系统解决接触荷电水雾连续供水时，水源与高压电源隔绝的难题。

Deep-Hole Inner Diameter Measuring System Based on Non-contact Capacitance Sensor

A precise aperture measuring system of small deep holes with capacitance sensors is presented. Based on the working principle of non-contact capacitance sensors, influence of the edge effect of gauge head is studied, and one capacitance sensor for measuring the aperture of the small blind holes or through holes is introduced. The system is composed of one positioning device, one aperture measuring capacitance sensor, one measuring circuit, and software. This system employs visual CCD and two-dimensional mic...
