查询词典 gas-forming

Here's the basic difference: when the planets in our solar system first formed, they were swimming through a disk-shaped cloud of gas. Their passage roiled and compressed the gas, and the gravity of the compressed gas in turn pulled on the proto-planets.

根本的差别在于：当行星在太阳系中首次形成时，它们正漂浮着通过一片圆盘状的气体云，于是它们前进的道路受到波动同时也压缩了气体，被压缩气体的引力反过来拉住了这些初生的行星。

富氧气氛下由于烟气量的减少以及锅炉热效率提高所带来的燃料量的减少使得烟气中的粉尘量得到一定的降低，为电站锅炉水平烟道烟气流速的提高带来了可能。

The experiments for determining the reaction kinetics of Daqing atmospheric residue were performed in a continuous flow, expanded bed rector. Four-lumped reaction kinetic model was developed to account for various feed and product fractions of Daqing atmospheric residue (gases, gas oil, residue and coke). The amounts of olefins and alkyls in the gas products were further analyzed to determine reaction kinetics of gas product distributions. Hence, a combined five-lumped reaction kinetic model was obtained for catalytic pyrolysis of Daqing atmospheric residue. The kinetic constants both in four-lump model and five-lump model were evaluated. A simulator for catalytic pyrolysis process was developed by incorporating the five-lumped kinetic model into the hydrodynamic flow model.
