    本文研究了各種送風參數對鄰接區的大小的影響，結果表明：送風溫差、送風量、送風湍流度以及送風口的摻混量等因素對其都有重要影響，在設計時必須仔細平衡這些因素，確定合適的送風口和送風參數，才能使設計更加合理，充分發揮出置換通風系統的優勢。
  4. The interface behavior between essence and ethylene - vinyl acetate copolymer pallets was studied so that necessary data were obtained to guide the preparation of fragrant masterbatch. the adsorption type and wettability between essence and the copolymer pallets were analysed by measurements of fourier transform infrared spectrum, surface tension, contact angle and specific surface area. the technical factors affecting absorptivity such as the charge ratio, temperature, pressure and stirring speed were studied by series of adsorption experiments. the results showed that the adsorption of essence on the surface of ethylene - vinyl acetate copolymer pallets is physical in nature. essence couldn ' t moisten the surface of ethylene - vinyl acetate copolymer pallets absolutely, but it could be soaked into the surface of the pallets partly. adsorptivity could be increased by enhancing the temperature, pressure and stirring speed, but the extension of adsorption time had little influence on adsorptivity

    研究了香精與乙烯/醋酸乙烯共聚物粒子之間的界面行為，以便為香型母粒的制備提供必要的理論依據.利用傅立葉變換紅外光譜、表面張力、接觸角及比表面面積等測定手段，分析了香精與載體之間的吸附類型和潤濕作用.並通過一系列吸附實驗，討論了配料比、溫度、壓力、攪拌等工藝條件對吸附量的影響.結果表明，香精在乙烯/醋酸乙烯共聚物粒子表面的吸附為物理吸附；香精無法完全潤濕載體粒子表面，但可以對其形成部分浸潤；提高溫度、壓力、攪拌速度可以增加吸附量，而延長吸附時間對增加吸附量貢獻不大
