| 中文摘要 |
| 对我国首座长波远程导航台的脉冲长波天线周围电场强度进行测试和有关理论计算。结果表明:发射机房内一般电场强度在0.5-3.6V/m,其相应脉冲峰值为38.5-276.9V/m,距离发射天线850-1100m的居住区内,场强为0.7-3.9V/m,峰值为53.9-300.3V/m;环境场强随与天线的距离增大而迅速衰减。在离天线1200m以外,场强衰减到极小值。 |
| 英文摘要 |
| A measurement and a theoretical calculation of long-wave pulsed electromagnetic fields (PEMF) around the antenna of the first long range navigation station in China were conducted. The results showed that the electric field intensities were 0.5-3.6 V/m (RMS) corresponding to peak values of 38.5-276.9 V/m in the PEMF generating room; in the residential area which is 850-1100 m away from the antenna, the electric fields were 0.7-3.9 V/m corresponding to peak values of 53.9-300.3 V/m;the PEMF decreased in environment with the distance away from the antenna and when the distance is over 1200 m from it,the fields tended towards minimum. |
