摘要
本文对由水平直元线构成的犁体曲面元线角变化规律公式进行了应用研究．结合碎土型犁体和翻土型犁体的设计实例，提出了公式的应用技巧和注意事项．利用导数方法，对两种犁体元线角变化律的大小进行了分析。通过实际设计，指出了原碎土型犁ｙ＝ｆ（ｚ）应用中的不便之处，提出了改进设想。
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.
