整约束
1.
Based on general variation calculus theory, the paper presents the strictly mathematical proof about necessity of norm functional maximum-minimum value existence in condition of integral item restriction, develops optimal mathematical model on the question of the speediest fall in condition of non-obstructing free fall and obstructing free fall, and shows how to solve them.

补充资料：非整数订价策略
非整数订价策略
odd pricing strategy
非整数订价策略(odd prieing strategy)给商品制定一个带零头价格的订价策略。这种策略的通常做法是:使价格的最后一位数为奇数或者接近于零的数。‘心容易给消费者造成一种价格偏低和订价准确的错觉，有利于刺激消费。不同的国家和地区消费者对数字偏好有所不同，在选择零头数字时应考虑这种差异。 (张玉峰撰马谋超审)
