Why do some astrologers include the quincunx sometimes, but never the semisextile?

为什么有些占星师有时会纳入补五，不考虑半六呢？

And I would say the quincunx is so miserable that we often find ourselves talking about that one as well.

我得说，那个梅花位真是让人头疼，至于我们常常也不得不谈论它。

Some of the most commonly used minor aspects, though there are many more, include the semi-sextile, which is 30 degrees, the semi-square, 45 degrees, the quintile aspect, 72 degrees, the sesquiquadrate, 135 degrees, and the quincunx, 150 degrees.

尽管有许多其他次要位，其中一些最常用的包括：30度的半六、45度的半方形、72度的五、135度的补四及150度的补五。

Also interesting in secondary progressions is when a natal planet that is in, say, a trine to another planet in the birth chart progresses into a quincunx aspect to the planet, or a sesquiquadrant in the birth chart progresses into a trine.

在二次推运中，一个有趣的观察点是：当出生图中某颗行星原本与其他行星形成三位，随着时间推移，这颗行星逐渐转变为与同一颗行星形成梅花位；或者出生图中原本处于补八位的行星，逐渐演化为与目标行星形成三位。此时，我们便开始深入关注这些次要位带来的影响。
