In other cases, a spherical model is used, and the primary distance calculation used is the great-circle distance (see Resources).

在其他情况下使用球面模型，所使用的主要距离计算为大圆弧长(参见参考资料)。

For the purposes of this article, I will demonstrate distances using the flat-Earth model and the great-circle distance and leave the rest to you to explore.

但是为了实现本文的目的，我将使用平面地球模型和大圆弧长距离来演示距离，其他方法留给读者探索。

Communicating long-distance can also feel a bit like the children’s game of “telephone, ” where each child in a circle repeats a message to the next child in the circle in a whisper.

进行远距离沟通也有点像在玩小孩子玩的传声筒游戏，孩子们围成一个圈，通过耳语把信息在圈子里面流转。
