pan out=取得進展；但跟平底盤(pan)有什麼關係？

Our collaboration is panning out as we have expected.

我們的合作正以我們所預期的方式進展。

We have the support from our sponsors, so I believe our investment will pan out.

我們背後有贊助商的支持，所以我相信我們的投資會有進展的(不會無疾而終)。

This is a slow-paced movie to nowhere. They try a few jump scares that don't pan out and plot that was very predictable.

這部電影步調很慢，看不出到底要演什麼。他們有嘗試用幾個嚇唬人的橋段，但結果沒什麼作用，而且劇情超好猜的。
