Second, according to field investigation and wind - tunnel experiment, some scholar s advanced that barchan dunes often appear in dynamic equilibrium shapes when th ey move along the direction perpendi cular to the dune ridge under the influence of unimodle sand - moving wind
風成沙的紅化和圓度特徵不宜作為判別其氣候意義的診斷性標志，應當結合動植物化石及石英砂顯微結構等線索來確定。 -
The diagnostic analysis for the sandstorm process on the base of height, temperature, pressure and wind etc output from the model shows that the upper cold trough, low - level wind shear, surface cold anticyclonic ridge, mesoscale cyclone and cold front are the main synoptic systems, surface cold anticyclonic ridge and cold front provide condition of wind force to occurrence of the sandstorm weather, the strong mesoscale cyclone before front makes pressure gradient before and after cold front obviously strengthen, moreover, and it increases obviously the temperature of the controlled area, as a result, the updraft movement caused by convergence before front strengthens
500hpa強鋒區、 700hpa切變和鋒前中尺度系統的強弱及位置變化是沙塵暴天氣發生發展到減弱的直接原因。地面冷高壓、地面氣旋及冷鋒是造成本次沙塵暴天氣的主要地面天氣系統。地面冷高壓及冷鋒為沙塵暴天氣的發生提供了風力條件，而中尺度氣旋使冷鋒前後氣壓梯度明顯增強外，又使所控制的區域增溫明顯，使鋒前輻合上升運動加強，為沙塵暴天氣的發生提供了熱、動力條件。 -
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。 -
Recent no - tillage and ridge culture commenced in the united states in the 1930s. it was developed to prevent the erosion of water and soil and to avoid the wind and water erosion. not until the atrazine herbicide was invented and successfully used in the 1960s was the nt technique succeeded and spread
近代的免耕始於20世紀30年代的美國，為了防治水土流失，防止風蝕和水蝕而發展起來的，到60年代，阿特拉津除草劑的發明利用，才使免（少）耕法得以成功應用和推廣。 -
The sanchuan hall has a 3 - section, double - ridge, single - eave roof. there is no courtyard in center to save space and to avoid the sandy wind
將三川門、拜亭、正殿一氣相連，是一座三開間兩進兩廂房式的廟宇建築，中間沒有中庭，以節省空間並防風沙。
