This paper mainly discuses the development about noise generator, linear degree mea- sure of the microwave radiator and to establish standard from integer.
their dielectric permittivity were measured at six frequency-points in the frequency region from 8 to 11.5 GHz in X-band. And measurement error's sources was analysed simply. Results of measuemrent can provide theoretical foundation for evaluation ofmicrowave power officient and the design of microwave radiator on extracting heavy oildownhole.
Conclusion Isolated endometrium of uterus can be destroyed when microwave thermocoagulation operation is executed. Length of central conduction of microwave radiator and the area of radiation must be regulated properly according to individual patient.
Methods divide 284 cases into treatment group and control group, for treatment group after their bowl movement give them Chinese herb medicine bath and dressing, then use microwave radiator to shine its surface once a day 10min/time for control group, besides microwave the rest is same with tneatment group.
In order to find an effective and harmless method for the male sterility, we have studied a method to raise the temperature of testicles by microwave heating and achieved satisfactory result. At first, the efficiency of sterility was not so identical, the reason was that power distribution of the microwave radiator was uneven. The radiative evenness of microwave radiator had to be improved before the sterility efficiency could be increased. We probed it as follows:We used the s...
The normal swine esophagus was heated by intraluminal microwave radiator for 30 minutes at 45°, 46°, 47°, 48° and 49°C. The animal was sacrificed 48 hours afterwards. The degree of heat injury was evaluated by a histopathoiogical score system with its maximum possible damage score as 100%. The acute heat injury at the temperature mentioned above was 2%, 17%, 50%, 40% and 87% respectively. The main features of heat damage were degenerative necrosis of blood vessels or thrombosis and focal necrosi...
The therapy principle and design of microwave prostate hyperthermia are described. This apparatus uses 915MHz microwave treatment for the prostate. The solid state microwave source and surface cooling system of special design only heats the prostate. The specially designed Foley duct and microwave radiator can be used for treatment by transurethral or transrectal. The temperature is measured and monitered automatically, and the measured data are recorded, displayed and printed ...
