| Abstract: | In this paper,it is pointed out that in the gravitational field of square-inverse propor-tion law,mechanical energy is a constant,and angular momentum a constant vector; besides,there exists a special kind of constant vector.It may be very simple and forceful to deal withsome problems in the gravitational field by employing this constant vector. |
