A towing system for ocean profiling multiparameter measurement;

The influences of towline on dynamic stability of vehicles were calculated and analyzed by using the simplified longitudinal small disturbance equation of towing system.

Calculation of coupling between the cable and the towedbody in the towed system;

Underwater towed system is increasingly apply marine research,ocean monitor with to survey device under water field such as being military extensively,it has a special use in marine environment and marine resources investigation and national defense construction.

The flight performance of a towed system is the basis for evaluating the system s feasibility.

It also discusses design of rolling transportation and dragging system,with a real rolling-dragging system.

It especially introduces the rolling technics design,track system design and rolling-dragging system design of portal crane.

Study on Sea Ice Geometric Parameters and Parameterization of Drag Coefficient Based on Image Analysis;

In the sea ice dynamics, the wind and current drag forces are the main driving forces during breaking and drifting of sea ice, and determination of the drag coefficients is the core for calculating the drag force.

In this paper,turbulent flux over canopy of field crops was calculated using Profile Gradient Method derived from Monin Obhov Similarity Theory and drag coefficient,Stanton number and Dalton number were also further defined.
