对如上图之类照片的初步分析表明该彗星中间光滑的区域有许多孔状结构，正直接将冰块泄漏到宇宙中。

Image denoising with second order non-linear diffusion PDEs often leads to an undesirable staircase effect, namely, the transformation of smooth regions into piecewise constant ones.

利用二阶的非线性扩散方程进行图像去噪易产生具有“阶越效应”的去噪结果，也即使分段光滑的图像变为分段常量的。

This allows wages and prices to adjust downward, giving depressed regions a competitive advantage that can attract new companies and thus smooth out regional disparities.

ECONOMIST: Can this union be saved?

So look to regions like Chile, where pinot is slurpy delicious with ripe cherry fruit and has a smooth, medium-bodied satin feel.
