If all of the material is heated to the glass transitiontemperature, no folding will occur.
若所有材料以玻璃转变温度进行加热，那就再不能进行折叠了。

It's a state function, so we're at constant temperature and pressure, and now we want to consider some chemical change or a phase transition or you name it.
这就是态函数，我们处于恒定的温度和压强之下，然后考虑某些化学变化或者相变，或者你想考虑的东西。

First, the surface temperature of the hinge must exceed the glass transitiontemperature of the material, which is the point at which the material begins to soften.
