摘要
由水利工程实例提出的数学问题得到式(1)定理,进而得到等腰三角形三边斜率之间的关系式(2).式(1)是有条件成立的.式(2)用于反弧段廓线计算,可将原超越函数问题变成可迭代求解问题,这大大方便了工程设计.
The theorem of eq.1 that is conditionally tenable is obtained from the mathematic questions raised from the actual construction cases hereinafter; and then the relation between the slopes of the three sides in isosceles triangle is reached by eq.2, which is found to be more convenient for the engineering design, as it can convert the primal question of transcendental function into that of iterative solution, when the profile of ogee section of a spillway dam is designed.
