Formula on direct calculation of water depth of uniform flow in rectangular open channel;

Then the author uses the result to design the arrangement of line sources and sinks in conjunction with a uniform flow.

Based on the concept of type of flow and experimental results,this paper shows that the roughness coefficient decreases with increasing of the depth of flow in an uniform flow,and increases with increasing of the depth of flow and energy gradient in non-uniform flow with M1water surface profile performed.

The productivity formula of horizontal well, which is based on the assumption of uniform flux as well as considering the branch horizontal well to be a vertical fracture, has been deduced by using the complex function theory when the number of branch is 1 or 2 respectively.

Synthetic fluid inclusions were studied in order to discuss formational mechanisms of homogeneous fluid and boiling fluid in detail.

Turbulence characteristics of non-uniform flow in a smooth open channel;

Based on experimental data measured with a Preston tube,bed shear stresses in uniform and non-uniform flows in open channels were compared under different hydraulic conditions.

Results of the flume experiments on non-uniform flow over a rough bed show that the vertical distribution of velocity on a channel section needs to be divided into two regions with different log velocity distribution equations.
