Article should expound the fact spend and impact on its development one-chip computer technology in sensor design,point out the sensor one especially The stability of the body should be put in the first place of research work,the technology of the one-chip computer combines with sensor,has improved the sensor Intelligent and standardization of anti-interference ability and promotion.

Based on the basic assumptions of the shallow water equation and demands of research on engineering problems, in combination with the definition of momentum coefficient, a depth averaged mathematical model is developed theoretically for calculation of flow field over submerged dikes.

It also introduces that the method of dispersion consuming energy of twin submerged dikes is used to regulate the cell vortex flow and improve the navigation condition on Xiaomi shoal.
