Using the thermodynamic conditions describing the coexistence of two phases and the stability conditions of equilibrium state, we have calculated the normalized temperature and the normalized pressure of the triple point ( t1, p1 ), the melting curve, vapouring curve and the sublimation curve. the whole phase diagram of the 2d monatomic l - j system is obtained
和杜宜瑾等人的方法類似，我們先給出了系統在相變點時的一些參數的數值，在此基礎上，考慮占據率q的因素，利用相平衡的熱力學條件及平衡態的穩定性條件，得到了二維單元l - j系統的熔化曲線、汽化曲線、升華曲線以及三相點的位置，從而給出了該系統的完整的三相圖。 -

The results indicate that drying thickness, radiant temperature and pressure of drying chamber are the most three significant factors. there ' s hardly any relationship between freezing rate and drying time, the sublimation drying time of slow freezing material is shorter than quick freezing one, but its desorption drying time is relatively longer, so the total drying time is approximately the same. the initial freezing temperature and freezing manner has little influence on vacuum freeze drying process
試驗表明：凍干厚度、加熱板溫度、系統的真空度是最重要的三個過程參數；凍結速率對總凍干時間沒有影響，慢凍物料的升華乾燥時間要比快凍物料短，但慢凍的解析時間相對較長，兩者的總凍干時間相差很小；初始凍結溫度對凍干過程的影響可以忽略。 -
It is indicated that the sublimation energy decreases linearly with increase of temperature sad pressure
研究表明，升華能隨溫度或壓強的增大而近似線性地減小。
