The new material was developed by Yellow River research center in Tsinghua University and the Yellow River Water Conservancy Scientific Research Institute.
They should correspond to the XieCai formula independently, the XieCai coefficient is calculated according to the Manning formula, and the gradient of energy slope, the side wall surface is equal to the total one; Secondly, the total water area is the summation of side wall, the bed surface water flow area (hydraulic radius x wetted perimeter).
Therefore, adjustment must first test to the certain flow rate, low water level, and high flow velocity to bring away the sands.
Change the water level, flow and model sand (Pseudochark) gradation and carry different groups experiment.

EPKS C300 SYSTEM 1.1 Hardware and Structure of EPKS C300 EPKS C300 process controlling system is the latest autonomous system produced by Honeywell, with Windows 2000 Professional as its operation system.
Quite to the opposite, too lower drum level will fasten the speed of water vaporization due to little water and heavy load in the boiler drum.
As a result of severe change of water quantity, normal circulation between drum and water is going to be affected.
If it is not timely controlled, all water in the drum will be vaporized, water circulation will be totally ruined.
In the process of control on boiler, the main level was level of water while the auxiliary ones were steam load and water supply flow.

The Behaviour of a Construction in Unsteady Conditions The professional public is becoming more and more aware of new methods of calculation, which are based on the principles of dynamic changes of physical conditions of constructions.
First water molecules on the surface are absorbed thanks to dipole interaction and van der Waals´ forces.
Once the absorbed water vapour has massed, the water is transgressed into the mass of material.
Decreasing temperature of the surrounding environment causes the increase of partial pressure of water vapour and increased transformation of water vapour into liquid state – condensation.
Gasser’s model does not consider capillary transport of water in construction materials.

. , Watercraft driving simulator can be better to complete the transportation protection, tactical formation, the complex hydrological and meteorological conditions, navigation, narrow waterways collision avoidance training in subjects such as simulation training, and school culture vessels command of professional officers, noncommissioned officers, and an important content of the sailors[1].
The Function of Watercraft Simulator Manipulate a Variety of Hydrological and Meteorological Conditions Watercrafts: Select certain waters, realistic three-dimensional visual simulation of the ship to be able to achieve during the day, night, fog, rain, big storm sailing.
In a variety of complex hydrological and meteorological conditions (see Fig. 4), the trainees to manipulate and control the car, rudder, anchor, cable operations, and under complex conditions on the watercrafts manipulation and collision avoidance training, could show the navigation information, such as the rudder angle, heading speed, water depth and romantic elements, and have the appropriate alarm function.
The waters of the ship's radar image are shown in Fig. 5[5].

The multiphase system of oil, water, gas, and solids may form multiple types of scour corrosion, which mainly include cavitation corrosion, turbulent corrosion, liquid blob shock, gas bubble shock, and solid particle shock[1,2,3,4].
The water phase in the flow may wet the pipe wall.
In addition to corrosive component content, the proportions of oil, water, and gas in multiphase systems and the change of phase state may affect corrosion severity.
