The purpose of this paper is to determine numerically the transient spatial distribution of electricfield in an electromagnetic pulse simulator excited by a timevarying highpower pulse source using an integral equation of the time domain. Some conclusions are drown from the data that a period of time are required for the electromagnetic pulse field to be established in the electromagnetic pulse simulator; the discontinuance of the current in the joint segment between conical region and working region is the main reason of the deformation of the field waveforms; The forward radiation of the current is the main reason for the field to be established and the afterward radiation contributes quite a little for the field to be established; The amplitude of horizontal electricfield is quite weaker than that of vertical electricfield....

In this paper,the integral equation of time domain is used to determine the spatial distribution of electric field in an electromagnetic pulse simulator.The calculated data are compared with the experimental ones. The investigation indicates that the numerical results agree with the experimental results and the waveforms of nuclear electromagnetic pulse with 10ns rising time can be established in the simulator.

By observing the changes in LDH、AST、CHE、K、Na+ contents in supernatant of cultured rat pituitary cells after electromagnetic pulse (EMP) irradiation the injury mechanism to pituitary cells was explored. Pituitary cells of Wistar rat was cultured in 6-hole plates. The cells in five plates were irradiated with high field strength EMP ( electromagnetic pulse) for 5 times within 2 minutes. The electromagnetic pulse simulator provided a high electric field intensity of 60 KV/m, with rise time 20-nsec and pulse wide 30/μS. Contents of LDH, AST, CHE, K+ and Na+ in the supernatant were measured using reagent boxes (Beijing Zhongsheng High-tech Bioengineering Company) at Oh, 1h, 6h, 12h and 24h following irradiation, respeetively. All data were analyzed by statistical software Spss 8. 0. The results showed that LDH and CHE contents in the supernatant increased significantly at Oh after irradiation with EMP (P<0. 05), contents of LDH, AST, CHE, K+and Na+ increased significantly at 1h and 6h after irradiation (P<0. 01) , and contents of LDH, AST and K+ increased significantly at 12h after irradiation (P<0. 05). However, contents of all of them were not statistically different from those of the controls at 24h after irradiation (P> 0. 05). Our conclusion is EMP could injure membranes of pituitary cells.
