density of energy meaning in Chinese

热能密度

It includes the requests of two respects : condense the pump radiation of large - scale diode arrays efficiently , thus in gain medium realize the high density of energy storage ; improve space distribution of the pump radiation , realize perfect pumping - uniformity in the gain medium
它包括两方面的要求:将大口径激光二极管阵列输出的泵浦光高效缩束,从而在增益介质内实现较高的储能密度;改善泵浦光的空间分布,在增益介质内实现较均匀的储能分布。
Liquid rocket engine is a thermal kinetic system , it runs under extremely strict physical conditions , such as high temperature , high pressure , strong erosion , high density of energy release , strong components parameters coupling . it is very difficult to establish accurate dynamic mathematical model
液体火箭发动机是一种在极端的物理条件(如高温、高压、强腐蚀和高密度的能量释放等)下运行的复杂的流体-热动力系统,部件参数强烈耦合,很难建立精确的动态数学模型。
