The paper mainly introduces some important property parameters of food concerned with cold process and related formula,such as water ratio,density,latent heat,breathing heat,specific heat,heat conductivity,heat diffusivity,etc.
本文主要介绍了与食品冷加工过程有关的几个重要物性参数及相关的计算公式,如含水率、密度、融化潜热、呼吸热、比热、导热系数、热扩散系数等,对于设计食品的制冷、冻结及冷链系统有重要的作用。
To meet this challenge, endothermic fuels that chemically decompose into energetic gases via cracking reactions and provide extremely high heat sink have been developed.
因此有人提出了吸热燃料的概念,即利用燃料发生的吸热反应来提高燃料的热沉,从而满足高超音速飞行的冷却要求。
