Pulse emission current at the inflection point on I-U curve of a thermionie eathode can be measured rapidly by means of a circuital technique. This method can prevent the eathode from suffering injury during the measurement. So that it can be used to compare the emission levels between different thermionie cathodes, and to monitor the changes of activation of cathodes during life test. The principle of the rapid-measure-ment of pulse emission current at the inflection point on I-U curve of the thermionie ea...             本文介绍了一种借助线路技术快速测定热阴极的脉冲拐点发射的方法。这一方法可避免测试对阴极的损伤,可提高测量的准确性,可用于比较不同热阴极的发射水平和监测寿命试验过程中阴极活性的变化。本文还叙述了热阴极脉冲拐点发射快速测量的原理,实现了拐点在伏安特性曲线上的自动显示,给出了鉴定拐点真实性的方法,并讨论了仪器的测量误差,通过对各种实用热阴极的大量测试表明,该仪器是有实用意义的。 文摘来源          The impregnated barium scandate dispenser cathode used in microwave tulbes, es-pecially in gyrotrons, has been investigated in following aspects: (1) pulse emission property and work function distribution; (2) electron initial velocity distribution in pulse operation; (3) the effect of pulse duration ratio; (4) anomalous Schottky effect under high electric field.

And it is found that more than 90% of X-ray events with importance ≥X1 appeared at the level≥C1 of background emission. Such a statistical rule may be interpreted as the result that the nonthermal electrons accelerated by solar flare to heat chromosphere plasma.             本文根据1986年1月-1992年12月期间，130个1-8的X级别的X射线事件与相应背景发射水平所作的分析，发现90％以上的X级X射线事件，都发生在X射线背景发射≥C1（10-6W／m2）水平上，这一统计规律，可从耀斑加速的非热电子对色球等离于体的加热得到合理的解释． 文摘来源   << 更多相关文摘
