Ценов方程和Mac Millan方程是非完整力学史上较晚出现的运动方程.这些方程的建立不仅有历史意义,而且有理论和应用的优势.本文对Ценов方程和Mac Millan方程的形成提供一些史料,并提出一些看法.
The Ценов equations and Mac Millan equations are motion equations later appearing in the history of nonholonomic mechanics.These equations not only have the historical significance,but also have the advantage of theory and application.Some relevant history data are provided for the formation and the development of the Ценов equations and Mac Millan equations,and our propositions are given.
