Numerical study of bubble absorption in vertical tube absorber;

The instantaneous wall shear stress and wall-liquid mass transfer coefficient for gas slugs rising through the liquid column in a vertical tube were measured by using limiting diffusion current technique.

A dynamic model with distribution parameter of vertical tube absorber was established.

Study on spiral flow in vertical pipe using the particle image velocimetry

Taking the object of transporting carbon black,analyzed the transportation pressure losing of level pipe、vertical pipe and bend pipe of the pneumatic transportation pipe line,gained the pres-sure losing formula of the three sorts of pipe line.

Hydraulic hoist of solid coarse particles in the vertical pipe is used in oil extraction, chemical engineering, ocean mining, coal mining and silt cleanup and so on.

Study on concentration of large size particles in vertical pipes by hydraulic lifting;

Based on the research results of experts,sets out from momentum,and analyses the momentum change of liquid and solids,and puts forward calculation models of settling slurry velocity distribution and friction loss in vertical pipeline.

Heat transfer for the liquid with low boiling-point in the vertical tube;

Many people think the state environmental protection agency should strengthen the administration through vertical management.

The essay dealt with the methods and effect of vertical nursing management,explored the way for the nursing department to implement the vertical management on staff members,money and property,and then made the nursing department a managerial department with the integrity of power and its responsibility as well as the relatively prope.

To solve these problems,corresponding measures can be taken by the NPC Standing Committee,for instance,the establishment of an audit committee,the vertical management of local audit organs,and improvement of the personnel system of auditing organs and the audit announcement system,and perfection of the audit accountability system.
