讨论了构造Birkhoff表示的Hojman方法.利用该方法重新研究Birkhoff对称性，提出一种关于该对称性的新见解，给出Birkhoff守恒量的新证明，并对该守恒量仅与Birkhoff张量相关作出解释.举例说明所得结果的应用.

The Hojman method for construction of the Birkhoffian representation is discussed. By using Hojman method, the Birkhoff symmetry is restudied. A new idea of this symmetry is presented. A new proof of the Birkhoff conserved quantity is given. It is shown that the Birkhoff symmetry depends only on the Birkhoff tensors. An example is given to show the application of the result.-
