The tendencies of the IGS in our country are:1 The tendency of accelerated flow.
Based on the axisymmetrical potential flow theory of an invicid incompressible fluid, the exact solution of an longitudinally accelerated flow passing an ellipsoid was obtained.
Results of weight loss in lab and field site show that corrosion rate of A3 steel can be accelerated flow of seawater, especially in the initial stage.
