以下是引用colorful_na在2007-9-26 10:07:00的发言:Right. In astronomical units-not perfect, but tantalizingly close. The value for Mars is off by...6 or 7 perrcenrt or so. It's..but it's within 10 percent of the average distance to Mars from the Sun. But i kind of have to skip the one after Mars for now. Then Jupiter's right there at 5-point something, and then Saturn is about 10 astronomical units from the Sun, Um, this pattern is known a Bode's law. 大家给看看这个句子。先开始听的时候决定速度还行就是没听出来意思,汗。 professor前面不是给出几个数吗. 他就用那个来表试planets和sun的距离. 你划红线的那几句是说, 这些数字不是很准确,不过它们都在6%-7%平均不超过10%的误差. 大概就是这意思. 个人认为. |
