But in experiment ii, the obtained result of measurement and examination is not better than control group 。 conclusion : mixed animo acids can be safely applyed to vessel cryopreservation instead of calf serum 。 the effect of the groups of the rapid freezing method is not better than the groups of the rate - controled slow freezing
而實驗ii的血管其內皮結構不清晰，內皮細胞超微結構變化較大。結論：復方氨基酸可代替胎牛血清用於血管的深低溫保存.速凍降溫方式對血管深低溫保存效果不及慢凍降溫方式。 -
Method : 120 rabbit vessels were randomly divided into three groups : the vessel of control group in cryopreservative medium containing calf serum were subjeted to rate - controled slow freezing ; those of experiment group i in cryopreservative medium containing mixed animo acids were frozen by the same method as in control group ; and those of experiment group ii in the same cryopreserative medium as in control group were subjected to rapid freezing
材料和方法：取中國純種家兔股動脈120段，隨機分為3組：對照組用含胎牛血清的保護液處理，以慢凍方式降溫；實驗組1用含復方氨基酸的保護液處理，以慢凍方式降溫；實驗組ii用含胎牛血清的保護液處理，用速凍方式降溫。 -
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。 -
The study results show that the minimum ac flashover voltage decreases with the increase of the ice amount accreted on the insulator surface by an exponential law, and the down - trend of the minimum ac flashover voltage will slow gradually with the bridging of the shed of the insulators by icicles, both the average saturated ice amount and the special exponent m of effect of ice amount for different insulators depend on the radius of shed and the air - gaps of the sheds of the insulators, and that the ac ice flashover voltage decrease with the decrease pressure ratio p / p0 ( rise of the altitude ) by power - law for different esdd and icing - states when the altitude is from 4000m to 5500m. the special exponent n, which show the effects of altitude on the flashover voltage, is various with the type of insulator, icing - states and the surface status of iced insulator etc., and that the minimum ac flashover voltage of iced insulators decreases by power - law with esdd or the freezing water conductivity for different ice amount and atmospheric
研究結果表明：在不同海拔高度和等值鹽密esdd下，絕緣子的最低交流冰閃電壓均隨覆冰量的增加而呈指數規律降低；當覆冰量增加到一定程度后，最低交流冰閃電壓隨覆冰量增加而降低的趨勢趨于飽和；不同絕緣子串的平均飽和覆冰量及閃絡電壓的覆冰量影響特徵指數m均與絕緣子的盤徑和傘距等因素有關；在海拔4000 5500m之間，不同等值鹽密esdd和覆冰狀態下，絕緣子的交流冰閃電壓隨海拔高度的增加（氣壓的降低）與p / p0呈乘冪關系降低，氣壓影響特徵指數n與絕緣子類型、覆冰類型、覆冰表面狀況等因素有關；當覆冰量和氣壓一定時，絕緣子的最低冰閃電壓均隨著等值鹽密（ esdd ）或覆冰水電導率的增加而呈乘冪關系降低，並逐漸趨于飽和。 -
Then the hydrogels of pva and pva - g - nipaam copolymer were made through freezing - thawing processes and the later hydrogels obtained in this method were found to exhibit obvious thermal sensitivity. in addition, the slow release of methylene blue from this kind of hydrogels was studied
採用冷凍-熔融的方法制備了pva ， pva - g - nipaam凝膠，發現pva - g - nipaam凝膠具有溫度敏感性，用相同方法對mb包埋固定並研究了不同溫度下緩釋規律。 -
Analysis indicates that the freezing - thawing is most important to failure of microstructure of soil ; the second is slow - soaking
分析表明凍融對土的微結構破壞最為嚴重，其次是慢浸。 -
Through two group tests on clayey soils with different water contents under quick - soaking, slow - soaking, freezing - thawing, different stresses ; the following studies were performed : the relationship between mechanical strength and microstructure dynamic environmental energyfield of clayey soil ; the interrelation between the microstructure dynamic environmental energyfield ; changing of external environment and medium environmental intrinsic of clayey soil
摘要通過兩組不同含水率的黏性土分別在快浸、慢浸、凍融、不同應力條件下的試驗，討論了黏性土力學強度特性與其微結構動態環境能場的本質關聯，分析研究了黏性土微結構動態環境能場、外部環境條件變化與其內在介質環境變化之間的密切關聯。
