  1. The results show that a warm high ridge at the middle level and transformed surface cold high over the plain provide a good background condition ; a cooling process produced by net surface radiation fluxes is the trigger and strengthening mechanism for the fog event ; the subsidence flow at the middle and low tropospheric levels is favorable for the setting - up and maintenance of stable stratification at the boundary layer and weak wind condition at the ground layer over the fog region ; the transportation of weak warm advection at lower levels and weak lift motion at the boundary layer play a very important role to the long maintenance of the fog event ; the intrusion of north wind accompanied by cold advection is a main dynamic factor of the fog dissipation

    結果表明：在中高層暖性高壓脊及地面變性冷高壓穩定維持的大尺度背景條件下，地表凈輻射引起的近地層冷卻是大霧過程的觸發和加強機制；中低空下沉氣流的存在有助於近地層的弱風條件和穩定層結的建立；低層暖平流的輸入和邊界層的淺層抬升是大霧長時間持續的原因；伴隨冷空氣南下的偏北大風是驅使大霧消散的動力因子。
  2. Abstract : have connected with ir target signature research, this paper deals with the principle and realization for the ir imaging terminal - guidance technology of an air - to - air missile in clutter backgrounds. the radiation signature of clutter earth backgrounds is analyzed, and the comprehensive analysis of the target ir radiation signature types of a military jet fighter as the mainly attacked target for air - to - air missile is gave. also we discusses the extraction and algorithm for target ir signature
