Behaviour of reversed flow during deep surge in centrifugal compression system 深度喘振倒流在离心压缩机系统中的发生特征
Research on the fractal reversed problem of IFS modeling method of natural scenery and image compression 自然景物建模及图像压缩分形反问题的研究
The results of test showed that lift effect under reversed loading would reduce the load-bearing capacity, and the shear friction can be provided by normal concrete compression force to transfer the shear at beam ends. 试验表明,反向加载时存在掀起效应,正截面受弯承载力应予以折减,梁端剪力摩擦作用能够抵抗梁端剪力。
