摘　　要：文中对MFB-100型电容式发爆器进行了实验评估。认为输出供电时间随负载电阻的增大而延长,引爆燃冲能随负载电阻的增加而降低。只要网络负载电阻不超过1000?、发爆器实际引爆冲能不小于7mJ就有保证。但当环境比较潮湿,可适当减少起爆雷管数或改变雷管连接方式。The experiment evaluation of MFB- 100 capacitive ignitor is carried out. The time of power supply prolongs with the increase of load resistance, while the impact energy of ignition decreases. If the load resistance of web is not more than 1000Ω, it can be ensured that ignition impact energy of ignitors is not less than 7 mJ. When the environment is moist, the number of detonators should be decreased and the mode of detonator connection should be changed.
