By applying the definitions of curvilinear coordinate in differential geometry and using the main electron trajectory as the curve axis, the first order and second order paraxial electron trajectory equations in the three-dimensional coordinate system are obtained. Some numerical results of these equations applied to the analysis of an electron-beam scanning flat cathode ray tube are given.
