近似度

The Eddington scheme is slightly more accurate in thicker optical depth region, while the two-stream DISORT is more accurate in the thin optical depth region where the solar zenith angle is less than 60 degree. Second, we compare the two two-stream schemes in a realistic atmospheric profile with gaseous transmission considered.

对于单层大气，Eddington 近似在光学厚度大的时候比二流离散纵标法更精确一点；而二流离散纵标法在光学厚度小且太阳天顶角小于60 度的时候更准确。

Two approximations to gradient have been introduced to reduce the computational complexity of the gradient based edge detection algorithm.

为降低基于梯度的边界检测算法的复杂度，常使用两种梯度近似算法。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
