Spacecraft works in the environment of high and low temperature, high vacuum and high-radiation, and its structural characteristic is effected by the space environment. 航天器工作于高低温、高真空和高辐射的空间环境中,其结构性能将受到空间环境的影响。
Based on the widely applied B-S kinetic mechanism model, and combined with the experimental conditions of the high-radiation flash pyrolysis, two numerical models were established corresponding to the thermally thin and thermally thick cellulose samples, respectively. 基于B-S动力学机理模型,结合辐射加热闪速热裂解的实验条件,分别针对热薄型和热厚型两种纤维素样品的热裂解构建了数学模型。
The results show that glucose is not the only production decomposing from oligosaccharide and another production decomposing from oligosaccharide will compete against glucose at high-radiation power. 分析表明:高辐射功率下,葡萄糖不是低聚糖分解的唯一产物,存在另一种产物与葡萄糖竞争分解低聚糖。
