A boundary integral method was developed for simulating the motion and deformation of a viscous drop in an axisymmetric ambient Stokes flow near a rigid wall and for direct calculating the stress on the wall.

The wall deposition of droplets is an important issue for the desulfurization efficiency and operating stability in the semidry flue gas desulfurization(FGD)reactors.

Subsequently,a mathematical model,based on dual film mass transfer theory and boundary layer theory,is proposed to calculate the SO 2 absorption capability of a single alkali droplet and to predict the desulfurization efficiency by spraying NaOH solution into downstream flue duct in coal fired boilers.

By analyzing the bubble formation process through the orifices in a viscous liquid,a theoretical model is developed for calculating the bubble diameter and the bubble formation process is simulated with FLUENT6.

By means of explicit expressions of pressure exerted on a rotor partially filled with a viscous liquid,it is that discussed dynamic stability of aforementioned rotor,obtained some valuable results and united Hendrick s and Christenson s results which are different.

Result:uteromyoma myxoid degeneration shows no specific manifestation in the disease procedure,it was possible to make a correct diagnosis by comprehend examinations.
