Finally, evaluation is made from the following aspects: mean, entropy, cross entropy, distortion of the correlation coefficients and the feasibility of the method is verified in this paper.

最后从均值、信息熵、交叉熵、扭曲程度、相关系数等方面对融合后图像进行了评价，验证了算法的可行性。

This article introduces the reason why there's existing the distortions of the micro align models and explains what is cross distortion and scan distortion 340 and how to match the different "340".

叙述了340光刻机发生畸变的原因，并解释了什么是交叉畸变，什么是扫描畸变，并对如何进行两台340光刻机的匹配进行了探讨。最后给出了试验数据。

Cutting roll-formed steel C-section to stub columns will produce different extent of cross section distortion along the lengths and cause additional initial geometric imperfections.

把辊轧成型的C形冷弯薄壁型钢构件切割成若干短柱，在短柱中将产生不同程度的歪曲变形，进而引起附加的初始几何缺陷。
