在物理中 温度是指当能量上升时无序度的大小
In Physics, temperature is defined by how disorder things get when there energy goes up
若在增加能量时混乱的量子系统变得有序
if you set up of weird quantum system that gets more orderly when you add energy
就会得到一个负温度
it has negative temperature
但是能量依然是正的
still positive energy though
变得有序的混乱的量子系统会得到负的开式温度 负的摄氏温度在冰箱就能找到
