Abstract

The invention discloses a method and device for reducing nonlinear wave hazards in a vertical rising cyclone phenomenon, and the method comprises the steps: building an AB system model equation based on a vertical rising cyclone parameter, and obtaining a first-order respiration sub-solution expression and a second-order respiration sub-solution expression of the AB system model equation; analyzing the first-order respiration sub-solution expression, and generating state transition analysis conditions by means of group velocities among all components in the first-order respiration sub-solution; enabling the first-order respiration sub-solution and the second-order respiration sub-solution to meet state conversion analysis conditions, and constructing a nonlinear converted wave and a nonlinear complex; adding periodic disturbance to a set initial solution of an AB system model equation to obtain a relation between a given disturbance frequency and an initial frequency in the initial solution; and counteracting or exciting the nonlinear converted wave and / or the nonlinear complex based on the relationship and the state conversion analysis condition so as to reduce the nonlinear wave hazards. According to the invention, part of non-linear waves are effectively offset or weakened, so that possible damage is reduced.

Description

technical field [0001] The invention belongs to the field of nonlinear mathematics and physics, and in particular relates to a method and a device for reducing nonlinear wave hazards in a vertically ascending cyclone phenomenon. Background technique [0002] Systems in physics can be roughly divided into two types, namely linear systems and nonlinear systems. A linear system can be understood as a system that satisfies the principle of superposition, and most linear systems are the result of simplified approximations to problems. For the real real world, only nonlinear systems can accurately describe a physical process. As an important part of nonlinear physics, the study of nonlinear waves began in 1834. British scientist Russell (Russel) first observed and recorded an isolated water wave set off by a ship beside a canal, as A scientist, Russell was acutely aware that this was no ordinary sine or cosine wave. But it is a pity that Russell's related research results did n...
