Petter's rule applies to two-dimensional patterns formed by two overlapping surfaces that alternatively appear in front of one another. It states that the surface with the shorter contours in the region where the surfaces look superimposed has a greater probability of appearing in front of the other surface. An experiment is reported the results of which show that Petter's rule is valid for chromatically homogeneous and for uniformly dense dotted patterns, and invalid for different kinds of chromatically inhomogeneous patterns. Petter's rule has been found to be valid when the overlapping surfaces have contours with gaps. It is proposed that Petter's rule derives from the dynamics of filling-in of contour gaps.
佩特法则适用于由两个交替出现在彼此前方的重叠表面形成的二维图案。该法则指出，在表面看起来重叠的区域中轮廓较短的表面比另一个表面更有可能出现在前方。本文报道了一项实验，其结果表明佩特法则对于颜色均匀和均匀密集的点状图案是有效的，而对于不同类型的颜色不均匀图案则无效。当重叠表面的轮廓有间隙时，佩特法则被发现是有效的。有人提出，佩特法则源于轮廓间隙填充的动力学。
