Completely automated theorem provers, such as model checkers, operate on an abstraction of the problem. 象模型检查程序这种完全自动化的定理证明程序是在问题的一个抽象上操作。
The images will be zoomed in by interpolatory subdivision and no intermediate continuous surface model should be established. 该算法无须建立中间连续图像模型，能自适应地插值，而且插值系数可为任意正实数。
