although there is no test result to compare, deformed shape net is also write in this article. There are research papers consisting of five parts: The first section is an introduction, the paper introduces the research background, and domestic and foreign research progress on the net hydrodynamic characteristics ender water flow；The second section introduce the basic idea and the basic theory of SPH method；The third section applies SPH method to simulate Poiseuille flow simulation, the results compare with the series solution and which reach the conclusion that SPH method is feasible and accuracy to simulate two dimensional uniflow; The fourth section simulate three dimensional uniform flow in the tank by using two kinds of SPH numerical simulation methods, the result is that apply SPH method with space physical stress is more in line with the actual sink flow process; The fifth section is the numerical simulation about the interaction between plane net and flow interaction based on SPH method, study and meanwhile show that the flow field form around the plane net, net total force size and deformed shape at each time, and let each part of the simulation results to compare with the test results, and analyze the cause of the error. The appendix section is public research programs written according to the study issue, the key technical solution is accomplished by writing the relevant procedures, the purpose of this program is as a reference for open the back of researchers continuing to study related subjects. Finally, the main research results obtained are summarized in this article, at the same time we prospect hydrodynamic characteristics of the research about plane net, circular net cages, clothing and so on . Key Words：Plane net；SPH Method；Hydrodynamic behaviors；Numerical simulation 目 录 摘 要........................................................................................................................
