When the new masses were used in the orbital equations, Uranus and Neptune were right where they were supposed to be.

当在轨道方程中使用新的质量进行计算时，天王星和海王星就正好在它们应该在的位置了。

Timing these events accurately could then be used to plug numbers into the orbital equations and get the length of an AU.

精确地计算出这些事件的时间，然后就可以把数字代入轨道方程，得到 AU 的长度。
