Norder to find the best high-voltage electrostatic radiation seed program, to select two different kinds of cucumbers, vegetables, paddy rice seeds, each seed be divided into 5 experimental groups, and be treated by high voltage electrostatic field (HVEF) at different field strength and time, and testing and statistics of the seeds vigour at germination stage. The results indicated that the greater the radiation field to same seed, the shorter radiation time is required, and vice versa. For each species, E•t tends to a constant (the constant is different in different species). Be proved by mathematical derivation that the HVEF radiation transport essentially energy to the seed, and then will be able to find the best way for HVEF radiation seeds.

Pasteurized whole, 2%, and skim milk were inoculated with Listeria monocytogenes Scott A and treated with high-voltage pulsed electric field (PEF). The effects of milk composition (fat content) and PEF parameters (electric field strength, treatment time, and treatment temperature) on the inactivation of the bacterium were studied. No significant differences were observed in the inactivation of L. monocytogenes Scott A in three types of milk by PEF treatment. With treatment at 25°C, 1- to 3-log reductions of L. monocytogenes were observed. PEF lethal effect was a function of field strength and treatment time. Higher field strength or longer treatment time resulted in a greater reduction of viable cells. A 4-log reduction of the bacterium was obtained by increasing the treatment temperature to 50°C. Results indicate that the use of a high-voltage PEF is a promising technology for inactivation of foodborne pathogens.

Silicone Rubbers

The electric field distortion caused by the high voltage current environment in the cable terminal will greatly increase the failure probability and reduce the operation safety; therefore, it is necessary to ensure the uniform distribution of the electric field in the terminal. This paper briefly introduced the high-voltage cable terminal and non-linear materials. The traditional silicone rubber and the silicone rubber added with nano-SiO2 were prepared. The electrical conductivity of the two silicone rubbers was tested, and the electric field of the cable terminal was simulated. The results demonstrated that the nano-SiO2 improved silicone rubber had a higher non-linear conductivity and was less affected by temperature. The calculation results of the simulation model also showed that the distribution of the internal field strength was more uniform, and the maximum field strength on the reinforced insulation was smaller after the improved silicone rubber was used as the reinforced insulation.
