Thus, our planet as a whole can grow more complex because thesun pours heat and light onto it, and the greater entropy associatedwith the sun’s nuclear fusion more than rebalances the scales.

所以，地球作为一个整体，是可以变得更加复杂的，因为太阳将光和热传递给它；相比地球自身的变化，地球的熵与太阳的核聚变关系更为密切。

There are many kinds of image fusion methods, such as information entropy, mutual information, mean square error, peak signal to noise ratio and mean grads.

医学图像融合的效果评价方法有很多，如信息熵、 互信息、均方值、峰值信噪比和平均梯度等。

Experimental result shows that the correlation coefficient between perceptual quality and entropy is only 0.41, the entropy method is difficult to assess color fusion images for night vision.

统计分析结果显示，“感知质量”与“熵”的相关性系数只有0.41，说明熵统计方法在彩色夜视融合图像质量评价上存在困难。
