Although problems were raised by Whitehead [3] and Eddington [4] on Einstein's theory of measurements, they are soon forgotten since nobody was able to solve them.

虽然Whitehead 和 Eddington对爱氏的量度理论都提出了疑问，由于无人能解决疑难，便很快地被忘却了。

We compare the difference of two-stream DISORT method and Eddington method from simple layer to a realistic atmospheric profile. First, we compare the difference in simple layer.

分别比较了二流离散纵标法和Eddington 近似在单层和实际大气中的差异。

Up-to-date, four models of the radiative transter processes have been developed: the two-stream Eddington approximation; the Eddington factor iteration; the ray tracing method and the Monte-Carlo method.
