Using acoustic emission, you know, this little noise that you hear a structure emit, sing to you when they are stressed, and reveal the damage going on, there's a collective phenomenon of positive feedback, the more damage gives the more damage, so you can actually predict, within, of course, a probability band, when the rupture will occur.
我们采用发声原理， 也就是一些材质在受到压力的时候发出的噪音， 告诉你损害正在发生， 这时候也会有一系列的积极反馈， 也就是一点破坏会带来更多的破坏， 所以你就可以预测， 当然是在一定的概率范围内， 何时会发生破裂。
