A novel concept of compact industrial furnace isproposed, in which tube with static mixer for partly intensification is determined. 2 A virtual engineering scale-up approach is put forward. The key points toimprove the scaling-up efficiency include two tools: one is rapid generationtechniques for computational models in which a re-use library is built, the otheris rapid prototyping manufacturing, employed for rapid generation forexperimental models.3 The tube is the key component for industrial furnace. Material microstructure,high temperature strength, and casting process of the tube with static mixer arediscussed as compared with those of traditional tube. Some special features ofthe static mixer tube are demonstrated.4 An evaluation method of velocity-based disturbance effect of fluid field wasproposed.

We find that model LBGs can have the same Two Point Correlation Funtion over the range of observable separations even though the cosmology and/or galaxy formation model are different. Moreover, with similar galaxy formation models, different cosmologies can result in both the same TPCF and the same PVD.

进而发现：(1)即使宇宙学和星系形成模型均不同，模型Lyman Break星系在可观测的尺度上也可以表现出一样的两点相关函数；(2)另外，不同的宇宙学模型可以预言相同的TPCF和PVD；(3)然而，不同的星系形成模型即使保持TPCF一样，也将预言截然不同的PVD。
