Low-Level Microwave Radiation Effect on Nerve Pulse Conduction Velocity

Summary This study is aimed to investigate dependence of nerve pulse conduction velocity on low-level microwave exposure. The changes in fiber membrane permeability or myelin sheath, caused by microwave, should affect nerve pulse conduction velocity. Experimental investigation was carried out for nerve pulse conduction velocity with and without applied microwave field and different orientations of its polarization to the nerve fiber. Microwave radiation of 450 MHz was applied polarized perpendicular or parallel to the nerve fiber. The measured field power density at the skin was 0.87 mW/cm². Special program was developed for calculation of the nerve pulse conduction velocity in LabView environment. The right nervus medianus motor nerve fibers of 35 young subjects were under the study. The experimental protocol included ten measurements in every cycle of five different exposure conditions. No changes in average values of the conduction velocities discovered in different exposure conditions. Theoretical calculations based on Hodgkin-Huxley model confirm only a weak possible effect. The results showed that low-level microwave radiation did not cause statistically significant change in nerve pulse conduction velocity in human motor nerve fiber.

Investigations on removal of SO2 from flue gas by aerosol formation in pulsed corona discharge process

The removal of SO₂ from flue gas by pulsed corona discharge in presence of ammonia was experimentally investigated. The results showed that the SO₂ removal mainly depends on thermal reaction of SO₂ with NH₃ and enhancements of 0%—25% by pulsed corona discharge in the range of the specific energy 0—5 Wh/Nm³. The aerosol mass concentration, mainly composed of ammonium sulfate, increased with specific energy dissipated into the reactor. With an initial concentration of 2000—2100 ppmv SO₂ and energy consumption of 3 Wh/Nm³, when a stoichiometric amount of ammonia is injected, the removal efficiency of SO₂ and percentage of ammonium sulfates in reaction products are all ≥80%. The collection efficiency of the reactor for aerosol is about 74% at a flue gas temperature of 60 to 65℃ and a water vapor content of 9% to 11% volume.     

数字地震台网脉冲标定自动检测软件

为了保证数字遥测地震台网的地震监测和速报质量,在<地震观测技术规范>规定各遥测台站要每天(甚宽带要每月)定时进行脉冲标定,并每天检查脉冲标定的幅度和周期变化,当发现脉冲标定波形的周期发生明显变化或脉冲幅度变化＞5%时,应及时检查修复.以前天津台网定时进行脉冲标定,但脉冲标定周期和幅度都是通过值班人员人工检测,并记录在值班日志上的方法进行检查的.现在我们编写了<脉冲标定自动检测软件>,软件每天能自动完成检测并将结果通过对话框的方式显示在微机上,使这项手工费时费力的检测工作变成抄表式操作.
