The amplitude is negative, so it's positive.振幅是负的 所以动能是正的 -
Yeah. So what color would we make it?没错 那我们用什么颜色标记 -
Green again. Okay, so if you're -- you can have --还是绿的 这个例子表明 -
be curving down or curving up and still be positive;无论向下还是向上弯动能可能总是正的 -
curving down if you're above the baseline,如果高于基线就向下弯 -
curving up if you're below the baseline. Right?低于基线就向上弯 -
So as long as you're curving toward the baseline,只要是向着基线弯曲 -
towards Ψ=0,基线是指函数值为零的地方 -
the kinetic energy is positive.动能都是正的 -
How about here?那这一点呢 -
Zack? Which way is it curving?扎克 这一点向哪边弯曲 -
Curving up or curving down?向上还是向下
