1. To meet the needs of high electron current density photocathodes, the processes for preparing cesium antimonide have been studied.

2. The formation process of the electron current in a neutron tube is discussed.

3. Based on the theory of electron current collected by probe, that the maximum derivative of electron current with respect to probe potential corresponds with the plasma potential is presented.http:///electron current.html

4. The secondary backscattered electron current is used to modulate the intensity of an electron beam in a cathode ray tube(CRT).

5. The optimum parameters, such as electron current and voltage for ionization, acceleration voltage, retarding voltage, gas inlet pressure, were determined by experiments.

6. The causes of disturbing electron current in quadrupole mass filter with Farady cylinder as an ion detector are described.

7. However, when electron current exceeds a certain value, an abnormal elastic electron peak can be observed, because the channeltron works in saturation mode.

8. The calculated results show that the electron current injected into the base region is not affected, but an increase of the base hole current is increased with the lifetime reduction.

9. In EDM process with tool as anode, tool wear is largely produced by electron current in gap during the frist hundreds nano seconds of the spark ignition.

10. Nevertheless, there were no any affected factors could be observed, such as electron current, orientation of electrodes, temperature and gel concentration.

11. The invention has the advantages of high stability of the emergent electron current, small noise baseline and the like.

12. And the other is to use the recordings of the electron current waveforms in the gas mixtures studied in a discharge chamber.

13. The system reconstructed traditional B2012A gantry plane electricity control by using PLC and electric power, electron current technology.
