  1. 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。
  2. Release of silver iodide ( agi ) into an existing supercooled cloud ( i. e., air temperature between - 39 and - 5 celsius ) can convert water vapor to ice crystals, which is called sublimation

    將碘化銀播灑至已形成的過冷卻雲中（既空氣溫度在- 39攝氏度? - 5攝氏度）能將水汽轉化為冰晶，這個轉化過程被稱為凝華。
  3. The vatiations of the sublimation energy with temperature and pressure are discussed according to the clapeyron equation

    摘要從克拉珀龍方程出發討論了金屬的升華能隨溫度和壓強的變化規律。
  4. As a super refractory, nature flaky graphite has many advantages such as high thermal conductivity, high thermal shock resistance, excellent high - temperature strength, excellent machinability, high sublimation temperature and low thermal expansion coefficient. unfortunately, the poor water wettability, low density and flaky structure of graphite surface limit its application with large quantity

    天然鱗片石墨以其熱膨脹小，導熱性、抗熱震性和化學穩定性好等諸多優點而成為適應鋼鐵冶煉苛刻環境耐火材料的原料，但石墨在水中的潤濕性、分散性差以及在空氣中易氧化等缺點限制了它的進一步應用。
  5. During winter nights and under clear skies, the ground surface is cooled rapidly by radiating heat off to space. the air temperature near the ground will also fall and when the grass temperature drops below zero degrees celsius, hoar frost will form by direct sublimation of water vapour onto the grass surface

    在冬天的晚上，如果天氣晴朗，地面的熱量會透過輻射快速散失，貼近地面的空氣也同時降溫，當草面溫度降到攝氏零度以下時，空氣里的水蒸氣便會在草面凝華成為白茫茫的霜。
  6. 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。
  7. The researching results show that a chemical transport agent introduced into our system can avoid the congruent sublimation condition and help to grow znse crystal under relatively low temperature. this route will reduce the production cost of znse single crystals

    兩種晶體西北工業大學博士學位論文生長實驗證明，輸運劑的引入可以降低znse晶體的氣相生長溫度，避免了znse的氣一固一致升華范圍過窄對znse單晶生長的限制，從而可以簡化工藝，降低成本。
  8. 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。
