ABSTRACT: By using image processing software, based on the coordinates of clear points in images and the theoretical coordinates of the points in the reference coordinate system, the coordinate relation multinomial of pre-and post-correction control points can be established by means of the digital image correction technique and the coefficient in the multinomial can be sought on the basis of the coordinates of a certain number of control points.

前言 考古绘图一直是考古学研究中不可或缺的重要技术，能够反映考古遗迹的分布状况或者典型器物的多重特征。但是随着考古学研究的深入和对相关技术手段需求的增加，考古绘图技术却始终停留在通过直尺等量取数据、再使用直尺和铅笔绘图的水平上，成图精度很低，周期较长，图形品种单一，远远不能满足现代考古学研究的需要。

Therefore, from the point of trade society, this paper studies the coordination conditions of several contracts among competitive supply chains by adopting Newsvendor model and game theory. The contracts considered include wholesale price contract, buy-back contract, revenue-share contract, quantity-flexibility contract and sales-rebate contract. According to this paper, trade society can coordinate enterprisers for more profit, acquire the modes of supply chains coordination and obtain the design approach of contracts to coordinate two competitive supply chains.
