In addition, the reactant ion yield can be effectively increased by choosing a proper temperature in drift tube, and improves the sensitivity and selectivity of system.
选择合适漂移管工作温度，能有效地增加反应物离子的产量，从而提高系统检测的灵敏度和选择性。

It is suggested that the instability is excited in the low density plasma when the electron beam drift velocities exceed the ion acoustic speed.
