China Environmental Science. 2002,22(3) ：272~276 Abstract：In order to get the distribution of power frequency fields produced by 110kV high-voltage transmission (HVT) lines in uptowns, electromagnetic field in the typical residential uptown near the 110kV HVT lines was measured; and the data with the distribution data of electromagnetic fields on the unoccupied regions are compared with the theoretically calculated data. The results show that the uptown building has significant attenuation effects on the electric fields produced by the lines; but no effects on the magnetic fields; and the building intensity has close correlativity with the intension of electric fields, but has no correlativity with that of magnetic fields.
