The paper works out the ice crystal spectrum distributing in the different macroscopic and micro - backgroud of the cloud ( ie, the thickness, the temperature and the supersaturation with respect to ice of the nucleation layer ). this paper also works out the amount of catalyst which is allowed in the cloud nucleation layer according to the different quantity of the supercooled water, the density of the supersaturation of the vapor with respect to ice. simultaneously, the paper discusses the i nfluence of remaining time when seeding artificial ice nucleus in the different ascending - velocity and altitude, and elicits the proper seeding altitude of the catalyst
以此解為依據，得出了不同均流時，人工引入冰核在核化層存留時間，再以此時間作為人工冰核凝華增長時間，求出不同的雲宏微觀背景（如核化層厚度、溫度、冰面過飽和度等）下的冰晶譜分佈，經和實際資料比對符合相當好。進而求出核化層中不同過冷水量、冰面過飽和水汽密度下雲核化層可允許的催化用量。同時討論了不同升速，不同高度引入人工冰核時對其存留時間的影響。 -
The development of mass transfer in the system of vapor - liquid - liquid three - phase distillation from trays was introduced, the effects of the hydrodynamic conditions e. g. vapor velocity and ratio of liquid to vapor loading and physical properties of liquid phase, including surface tension, interfacial tension, viscosity or dispersion viscosity, density, relative volatility etc. and the volume ratio of oil to water on mass transfer were discussed systematically, the influence of the second liquid on mass transfer efficiency was also investigated, a gnat deal of viewpoints and suggestions having been put forward in this paper are significant important for optimizing design of distillation tower
摘要介紹了氣液液三相精餾塔板傳質性能研究的進展情況，討論了氣速、液氣比等操作條件，表面張力、界面張力、液體的粘度或分散粘度、密度和相對揮發度等物系性質以及油水體積比等多種參數對傳質效率的影響，探討了第二液相的存在對傳質的影響，文中的許多觀點獲和建議對于優化精餾塔的設計具有重要的指導意義。 -
The experiments reveals that : the amount of water vapor transfer is affected by both water content gradient and the value of water contents, when the water content of one end is approximate, the water content gradient increases, then the amount of water vapor transfer increases ; when the water content gradients are approximate, the amounts of water vapor transfer can get great differences if the water contents are different, under this condition when the water content of the dry soil is very little, the amount of water vapor transfer is much greater ; the differences of density hav n ' t great effects on water vapor transfer, but have some effects on the admixture transfer, when the density is smaller, the amount of admixture transfer is greater. the water vapor transfer finishes more quickly and need less time, and the liquid water finishes more slowly and need less time
當一端含水量一定時，增加含水量梯度，則氣態水遷移量增大；當含水量梯度相近時，氣態水遷移量隨含水量不同可能相差很大，這種情況下當較干段含水量特別小時，氣態水遷移量相對較大；密實度的大小對于氣態水遷移的影響並不明顯，但對液態水和氣態水的混合遷移有一定的影響，在相同的實驗時間內，土體密實度較小，則混合遷移量相對較大；氣態水遷移完成速度較快，所需時間較短；液態水遷移完成速度較慢，所需時間較長。 -
According to specialists ? experience, such dangerous factors as water temperature, water pressure, oxygen density in the tank, the temperature and pressure of water vapor, ect. as well as control rules are made out in safety regulations for oil tankers. by using fuzzy logic ( min - max reasoning ), all sorts of fuzzy information are processed so as to simplify the control procedure in addition to realize it
其方法是利用模糊邏輯控制的優點，不需建立精確的數學模型，根據專家的經驗，油輪安全規則制定出各危險因素（如水溫，水壓，氧氣濃度，壓力，溫度等）的模糊隸屬函數和一系列的控制規則，利用模糊邏輯（ min max ）來處理各種模糊信息，使整個推理過程運算簡單易於實現。
