electromagnetic pollution 中文意思是什麼
-
To keep the environment people live in, we should restrict or prevent many kinds of pollution, which includes electromagnetic radiation pollution. while we are considering setting up base station or evaluating the electromagnetism pollution of environment, we can measure on the spot. to save time, hard work and cost taken by measuring on spot, it is necessary to calculate and analyze the electromagnetic wave propagation in urban area
在對現有電磁輻射源（如移動通信基站、廣播電視發射天線等）環境電磁污染狀況進行評估時可以進行實地測試，但是對在建或擬建的輻射源則不可能進行先測試，同時為了避免實地測試的費時、費力和較大的測試費用，通過計算機來計算分析城市環境電波傳播顯得很有必要。 -
