Secondly, different changes in river programs, it's outside of river bend shows erosion status in different flood frequencies. And the localscour depth is different with different bend radius.
It shows that the amplitude is too large outside the reverse radius and the electric temperature profile is too broad before collapse and the central temperature is too low.
结果发现，在反转半径外的振幅太大，并且在破裂之前温度剖面太平坦，而中心温度较低。

We find that when the collapsing bubble approaches its minimum radius, a high pressure layer just outside the bubble is generated which gradually moves outward and subsequently forms a shock wave.
