| Abstract: | This paper deals with the application of the angle formula of horizontal line by which plow bottom was formed. The application techniques and points for attention of the formula in use were put forward with the designs of oldland bottom and general bottom The rate of the angle changed with the height of horizontal line was analysed by means of derivative. The inconvenience of the formula (y=f(z) )of oldland bottom was pointed out and Modification ideas were given. |
