摘要
扫雷艇在执行扫雷作业时,可在艇上产生一定强度的交变磁场,使艇员全身暴露于强磁场环境中。磁场作为一种物理环境因素对生物体产生影响,已有许多文献报道,但有关低强度交变磁场对人体的影响则报道不多,迄今仍以动物实验资料为多见。为了观察扫雷艇磁场环境对艇员大脑信息功能的影响,并探讨电子计算机分析技术在电磁生物学研究中的应用,本文采用封根泉等提出的方法,根据生物控制论的原理。
Based on the principle of biological cybernetics the computer analysis of cerebral information functions was performed in 9 crewmen after intermittent and whole-body exposure for four weeks to ULF and alternating magnetic field of the mine-sweeper.The results indicated that under ULF and alternating magnetic field with low intensity (1-8.5mT) exposure the power spectrum of spontaneous and evoked EEG was slightly affected, and some regulative actions were found for the dynamic characteristics of cerebral information control system. The results could provide some bases for studying the hygienical standard of magnetic field in the mine-sweeper in the future.
