• 摘要：推导了不等线径、不等线距圆线组合电除尘器伏安特性计算关系,利用不等线径、不等线距圆线组合对管状芒刺类电晕极作了近似简化处理.采用静电场与电晕电场相叠加的办法建立了管状芒刺类电晕极电场分布的一种计算方法.与实验值对比表明,该方法的计算结果是可靠的.

• Abstract：A calculation method of the voltage-current relation of electrostatic pre-cipitators was deduced for the corona electrode geometry with different wire diameter and different wire-to-wire spacing. Using the geometry with different wire diameter and different wire-to-wire spacing,the corona electrode with tube-type spike was approximately simplified. A calculation method of electric field strength distribution for corona electrode with tube-type spike is set up by combing the electrostatic field with the corona field. The verification has shown that the calculation results are reliable.
