2.The temperature difference between oasis and surrounding desert drives an oasis breeze circulation, in which there is the downdraft over the oasis and the updraft over the desert.
这种温度差异使绿洲风环流产生,并且使绿洲区产生下沉运动、沙漠区产生上升运动。
3.The thermal properties of biomass fuels such as cotton stalk briquette in the small furnace of biomass pyrolysis and combustion with moving bed and updraft was investigated.
研究了棉杆成型块等生物质固体燃料在小型移动层上吸式热解燃烧炉中的热特性。
