Abstract:
The paper brief ly introduces the measurement method for the velocity of bullet under w ater and the capture method for { x i , t i } data couple and analyses the difference of the law to the bullet movement betw een in the air and in the w ater. A displacement-t ime regression model suited to the bullet movement in water is introduced. In order to correctly ref lect the ant icipated error of the velocity, this paper discusses the calculat ion method w hich can judg e the standard error of the bullet movement velocity under w ater, and int roduces the f luctuat ion regulation to the standard error of the bullet velocity.
