在一般的情况下,确定带式输送机合理槽形的问题,乃是一个变分法的问题。要求找出曲线y(x)(图1.α),使得在附加条件■下,由积分所确定的面积
Under normal circumstances, the problem of determining the proper groove shape of a belt conveyor is a matter of variational law. It is required to find the curve y (x) (Figure 1.α) so that under the additional condition, the area determined by the integral
