The qualification of multipactor and the characteristic of the angle and velocity of secondary electron were study . bring forward a improved model of multipactor and solve it by a random sample made by monte carlo , as a result , a critical curve of multipactor was gained
2.
With the numerical solution , an internal condensation critical curve can be calculated out by condensation theory and depositing theory , on the curve , the enter water ability equal to the out water ability , which can be used as the basis to determine the occurrence of internal condensation . but the result doesn �� t coincide with the real completely . in this dissertation , we plan to get the critical curve by practical experiment results , because that the enter water ability only relates to the condensation density and the out water ability only relate to the volume ratio of the pneumatics system
