Calculation results reveal that the equivalent beamlength is more suitable to describe the beam size of vortex beam after propagation.
数值计算进一步说明，等效光斑尺寸更适合用来表征涡旋光束传输后的光斑大小。

The parameters considered include the mean beamlength of flue gas, the emissivity of gas, the film beat transfer coefficient and the enthalpy of flue gas.
这些参数包括烟气的平均辐射长度、烟气黑度、对流传热系数、烟气的热焓等。
