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。These may be either narrow informal elongations of the park, varying say from 200 to 500 feet in width and radiating irregularly from it, or if, unfortunately, the town is already laid out in the unhappy way that new york and brooklyn, san francisco and chicago are, and, i am glad to say, boston is not, on a plan made long years ago by a man who never saw a spring carriage and who had a conscientious dread of the graces, then we must probably adopt formal parkways

在戰略和戰術雷達制導導彈中，一項重要的工作就是對目標的準確跟蹤，這取決于導彈雷達對目標的準確定位。為了保護雷達天線不受外界環境的影響，天線罩被應用進來，但天線罩在保護天線不受外界惡劣環境影響的同時對天線電磁輻射產生某些干擾，使天線的電氣性能降低，影響天線的功率傳輸，更重要的是產生瞄準誤差。它使目標的視在位置與真實位置有一個角度差，這個角度差就是天線罩的瞄準誤差。Dlc and a - sic : h films were prepared by the rf glow discharge and the reactive sputtering method respectively. there were two reasons that we chose y rays, ultraviolet ( uv ) photons, and neutrons as radiation sources. one is that y rays, uv photons and neutrons irradiation are serious at outer space and / or nucleus irradiation enviromentthe other is that the study on y rays irradiation on the films is a new and an important directioaotherwisejirnited reports have been made of the investigation on the uv photonsjieutrons irradiation influences on these films
