3、Because of low vertical bearing capacity, especially horizontal bearing capacity, row-lock cavity wall has not enough bearing capacity, so that cracks are often found on row-lock cavity wall.
2、High frequency with strong level induced by interacting shock wave to cavity wall was expressed in calculation.
4、The speed of the gas flow in the reaction cavity can be lead to be equalized so as to not only protect cavity walls but also equally distribute the gas in the cavity.
1、During the shore period of observation, carcinoma node, dimension of the cavity, thickness of the cavity wall and volume of liquid in the cavity have dynamic changes.
