| 3. | The thickness obtained from the phase change heat is consistent with the one obtained from the optic microscope 用相变热得到的微胶囊的壁材厚度与显微镜测得的微胶囊的壁材厚度相一致。 |
| 4. | Through the study , the phase change materials on residential storing energy was obtained whose melt point is 16 - 28 c and heat of transformation reach or exceed 180j / g 通过研究确定出可用于建筑节能的相变贮能材料,其相变点在16 28 ,相变热达到或超过180j g 。 |
| 5. | 6 . although the ta concentration hardly affects the phase change temperature , the heat of phase transition reduces as the ta concentration increasing . it scarcely influences the thermal stability of capsules 6 、 ta对胶囊的相变温度的影响很小,相变热随着ta浓度增加而减小; ta对胶囊的耐热性影响很小。 |
| 6. | 5 ) as the deformation strain increases the reverse transformation temperature and thermal hystersis of tini film increase on the first heating , while the martensitic transformation temperature decreases and r phase transition temperature is constant 随预应变量增大, tint薄膜的第一次逆相变温度升高,相变热滞增大,马氏体相变温度降低, r相变温度无明显变化。 |
| 7. | 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。 |
| 8. | 7 . sodium chloride has slight effect on the heat of micropcm phase transition , but it easily leads microcapsules to stick together . for the microcapsules feeding more than 6 % sodium chloride in the emulsion , their super - cooling can be prevented availably ; however , their mechanical intensity and their thermal stabilities turn worse and they cohere each other 7 、 nacl对微胶囊的相变热影响较小,但容易造成微胶囊粘结;乳液中的naci浓度超过为6 %合成的微胶囊的过冷现象得到明显改善,然而,胶囊的机械强度与耐热性能均下降,微胶囊之间发生粘结。 |
