航天器运行系统大都属于变质量力学系统，研究变质量系统的运动方程是研究航天系统力学性质的基础。本文构造了变质量力学系统的Tzénoff函数，建立了用普通偏导数表示的变质量完整系统和非完整系统的Tzénoff方程，所给出的运动方程具有新的结构形式，该微分方程的建立对变质量系统的动力学研究具有一定的理论价值。

Most spacecrafts operation systems belong to the systems with variable mass .The equation of motion in the systems with variable mass is the foundation to make a further understanding of mechani-cal property within aerospace system .In this research ,the Tzénoff function in the mechanics systems with variable mass is constructed ,and the Tzénoff equation which was expressed by normal partial de-rivative in holonomic system and nonholonomic system is built .This equation of motion have new struc-tural form ,the built of this differential equation would also provide some theoretical value for dynamics research in the systems with variable mass .
