This paper establishes conjugate state variable and its variance matrix equations of dynamic system, and describes functional relation between motion state variable and its conjugate variable. Their scalar product formula is used for the calculation of trajectory deviation. The relative formula of scalar product trance of variance matrixes of state variable and its conjugate one is used for calculating influence of single or many disturbances on statistical performance of vehicle and other dynamic systems.
