• 中文摘要： 本文係採一冷卻、加晶種之批式結晶槽以決定鉀明礬之次成核速率式,在計算過程中所採用之數學為筒圖法(simplex method)及轉移式勒甘德多項式(shifted Legendre polynomials)。所得成核速率式乃以冪次式表之,其中包括溫度,過飽和度及懸浮密度等變數。然後並以模擬結果探討操作變數對粒徑分布之影響。
• 英文摘要： A cooling seeded batch crystallizer was used to determine the secondary nucleation kinetic expression for the potassium alum crystal. The mathematical techniques involved in the computation were Simplex method and the shifted Legendre polynomials. The nucleation rate equation was expressed by a simple power law model comprising three state variables, i.e., temperature, supersaturation, and magma density. Then the effects of operational variables on the crystal size distribution were discussed using the simulated results.
