摘要
根据实际问题,提出了曲线导数的概念,使得方向导成为曲线导数的特殊情形,并给出了曲线导数存在的充分条件,同时给出了曲线导数的基本性质.丰富了微积分理论.
The conception of curve-differential is put forward from actual problems. The direction-differential is the special case of the curve-differential. The sufficient condition of the existing curve-differential is obtained and the basic characters of curve-differential are investigated. The theory of differential-integral is enriched.
