层流

The geological and geophysical data show that in the lower crust of young continental tectonic units may occur pervasive, non-seismic, subhorizontal and ductile flow related to thermal softening. The laminar flow drives fault-block movement of the upper crust, results in the formation of orogenic belts and sedimentary basins, and causes coupling between ductile lower crust and brittle upper crust/mantle.

A linear correlation is found between the ratio of unstretched laminar burning velocity with and without the diluent and the dilution ratio.

有无稀释气时无拉伸层流燃烧速率的比值仅与稀释系数有关并成线性关系而与混合气浓度无关。

Markstein length increases with the increase of dilution ratio when equivalence ratio is less than 1.4, and the flame stability tends to increase with the increase of dilution ratio. The ratio of unstretched laminar burning velocity with and without diluent is only related to the dilution ratio and is little influenced by the equivalence ratio.

丙烷－空气－稀释气混合气随稀释系数的增加，火焰传播速率和层流燃烧速率降低，在当量比小于1.4时，随稀释系数的增加，马克斯坦长度值增加，火焰前锋面的稳定性趋势增加。
