1. Embedded in a flux of dehydrated b2o3 , melts of ge and ag etc . were undercooled by repeatedly treatment of melting and solidifying with a dsc facility , with undercooling of 190 k and 146 . 9 k respectively for ge and ag
   对半导体ge 、金属ag等样品的过冷现象进行了研究和分析。通过助熔剂包裹和反复熔化与凝固处理，实验得到的ge 、 ag的最大过冷度分别为190k和146 . 9k 。
2. 3 . for encapsulated pcms with less than 10 m in their average diameter , their temperature and heat of phase transition seldom change as their average diameter decreasing ; however , their crystallization peaks vary dramatically and the super - cooling becomes worse
   3 、对于平均粒径小于10 m的相变材料胶囊，胶囊的相变温度以及相变热基本不随粒径变化，而结晶峰变化较大，其过冷现象随着粒径的减小而加剧。
3. Differential scanning calorimeter ( dsc ) combined with melt fluxing technique was used to realize undercooling of melt and its specific heat was measured at the same time , and its thermodynamics were calculated simultaneously and compared to four well - known models
   本文将差示扫描量热法( dsc )和助熔剂处理技术相结合，研究了熔体的过冷现象，测量了过冷状态下熔体的比热，计算了过冷熔体凝固过程中的其它热力学参数，并与四种近似模型进行了比较分析。
4. At a given cooling rate , the degree of undercooling increases with increasing overheated temperature , and tends to be constant at last . it suggests that higher undercooling can be reached by increasing the overheated temperature in a stated range . at a given overheated temperature , the undercooling increases with cooling rates within the range of measurement
   在冷却速率一定的情况下，熔体的过冷度随着过热度的增大而增大，而随着过热度增大到一定程度，熔体的过冷度趋向于常数；这说明采用dsc与助熔剂处理技术研究熔体的过冷现象时，可以通过在一定范围内提高过热度来获得较大的过冷度。
5. Their properties have been investigated by using scanning electronic microscopy ( sem ) , differential scanning calorimetry ( dsc ) , x - ray diffraction ( xrd ) , thermogravimetry - differential thermal analysis ( tg - dta ) , infrared spectroscopic analysis ( ir ) , and gas chromatography ( gc ) , etc . the effects of the mulser ' s stirring rate and the emulsifier concentration on the properties of encapsulated pcms have been systematically studied , and nanopcms have been obtained by increasing the stirring rate or the emulsifier concentration . the influences of different nucleating agents on micropcm performances have also been investigated in detail to search for a suitable nucleating agent to prevent micropcms from super - cooling
