英文摘要： There are major friction resistance on the contace surface and lots of energy will be lost, when there are relative motion between fluid and solid. According to this problem, a new technology has been proposd that is bionic jet surface drag reduction, which is of great significance. We will analyse the jet surface drag reduction mechanisms of the shark's gills, reveal the influence factors of jet surface drag reduction, then establish the influence law between influence factors and drag reduction effect, and establish bionic jet surface drag reduction model; research the influence law between single factor an drag reduction effect in all the facotrs, and the influence law between many facotrs, then establish the mathematical model of many factors coupling drag reduction characteristics; study the energy conservation effect of bionic jet surface and the effect on system resistance of the bionic jet supply form, develop the supply strategy of bionic jet form, then estabish the bionic jet surface drag reduction system; research the bionic jet surface drag reduction mechanism on many factors coupling, propose a law that the bionic jet surface drag reduction is according change the relevant jet factors to affect area flow field, reveal the physical significance of the process that each influence factor restrict the
