The reinforcingrib arranged in the corrugated outer wall adopts a hollow structure.
所述波纹形外壁间设置的加强筋为中空结构。
2
The reinforcingrib can enhance the bearing capacity, but have little influence on the deformation ability.
用加强肋可以明显改善承载力，但对变形性能的影响较弱。
3
An effective control of cracks at oil-reserving bottom comes from increasing strength of the bottom by thickening reinforcingrib, and increasing frequency by reducing noise also achieves.
