An innovative model on particles impact heat transfer is proposed in our work, in which the effects of both internal thermal resistance of solid particle and contact thermal resistance between impacting particles on heat transfer are considered. 在分析颗粒碰撞传热机理的基础上建立了一个新的颗粒碰撞传热理论模型,该模型综合考虑了固体颗粒内部导热热阻及颗粒间接触热阻对颗粒碰撞传热的影响。
The inorganic shell can improve the internal domain thermal stability, mechanical strength and scratch resistance. 无机物外壳可以增强热力学稳定性、机械强度和抗拉伸性。
Research results indicated that the establishment of internal protect-mechanism and selection of proper cathode material with good thermal stability could improve the overcharge resistance performance of the battery. 研究表明:建立内在的过充保护机制,选择具有良好热稳定性的正极材料,可以提高电池的耐过充性。
