英文摘要：

The aim of the paper is to research the conformal invariance and conserved quantity of Mei symmetry for Tzénoff equations in holonomic systems .Firstly, the Tzénoff equations of holonomic systems is established .Then, the determining equations of conformal invariance of Mei symmetry for Tz énoff equations in holonomic systems are given.The conditions and the functions of the conserved quantity which is deduced by conformal invariance are obtained.Finally, application of this new result is presented by a practical example .
