本文对喷管元件推进剂掺混特性的泛化处理又向前迈进了一步。以一种新的方式给出了一些已被研究的元素的性质。以火箭推进剂体系为例，将它们的混合函数与归一化反应特征量函数相结合，推导出归一化反应特征量体系，并将其应用于某些推进剂体系。然后对反应和流体力学混合效应的组合进行了一般性的讨论，从而揭示了对反应体系中的混合效应的处理方法的要求。给出并讨论了元素混合特性的一些结果，由此抽象和概括地研究了基本参数在不完全混合和反应过程中的作用。给出了计算结果的实例，并对其进行了讨论，以显示总体趋势和要点。
The paper makes a step forward to the generalized treatment of the propellant mixing characteristics of injector elements. The properties of some elements that have been investigated are presented in a new manner. Their mixing functions are combined with normalized functions of the reaction characterizing quantity as the characteristic velocity of a rocket propellant system for example.The system of the normalized reaction characterizing quantity is deduced and applied to some propellant systems. Then the combination of reaction and hydromechanical mixing effects are generally discussed so that the demands to a suitable method for treating mixing effects in reacting systems are laid open. Some results of the mixing characteristic of elements are presented and discussed from which a mathematical procedure follows to an abstracted and general study of the effects of the essential parameters in the uncomplete mixed and reacting process. Examples of the results of computation are presented and discussed to show general trends and essentials.
