THE RESULTS ARE SUMMERIZED AS (1) THE TIME LAG HAS REDUCED TO BE 10% FOR A NONUNIFORM DC ELECTRICAL FIELD IN DRY AIR OF 1 ATM AT 22 ° IN TEMPERATURE, (2) THE REDUCTION FOR TIME LAG MENTIONED ABOVE IS DUE TO INCREASED INITIAL ELECTRON SEEDS NEAR CATHODE PLATE BY PULSED LASER- PRODUCED PLASMAS.

结果归结为：(1)在22°IN温度下，非均匀直流电场在1atm干燥空气中的时滞减小到10%；(2)上述时滞的减小是由于脉冲激光产生的等离子体增加了阴极板附近的初始电子种子。
