threshold 最起初的意思是門檻
但它卻被引申其他解釋,如在物理,或電子學科上也有用上threshold,但在這個情況下當然不是解作門檻。
因為人都必需把腳提高過門檻才能進入,所以 threshold,就被引申解作”產生某樣事情的最低條件”,如在某些電子零件,我們起碼要給它input voltage 3v,它才能運作,那時這零件的 threshold 就是3v。希望這樣解釋你會明白。

I don't think its a physical thing that you actually see. Cos we usually use this word to describe some sort of barrier/starting point that you need to oversome.
