Solving the State Equation of a System by Walsh Function

In this paper, We deal with the solution of the state equation of a system by the Walsh function, that is, we shall find the solution of a matrix differential equation by the Walsh function, and introduce a solution of the higher-order matrix differential equation. First, after a certain transform, we turn the higher-order matrix differential equation into a state equation. Then we find the solution of the state equation by the Walsh function. Finally after a certain transform, we obtain a solution of the higher-order matrix differential equation.

试论抗日战争对民族心态的影响

抗日战争对中华民族心态有多重影响。它促进了民族的认同感，使民族意识和民族凝聚力大为增强；它洗刷了民族的百年耻辱，使民族自尊心、自信心和自豪感大大提升；它提高了民族的政治觉悟，使民主、和平、进步的观念深入人心；它激发了民族的发展意识，使人们追求现代化和复兴民族的愿望空前强烈。上述这种积极健康的民族心态，必然会促进民族解放和社会进步。     

One modified method of characteristics used to analyze the multiconductor transmission lines

1.INTRODUCTIONThe analysis of electromagnetic compatibility becomesmorei mportant in the analysis of the multiconductortransmissionlines(MTLs).It provides the effectivemethod for designing the MTLs.Several methodsbased on frequency domain and ti me domain tech-niques have beenrecently proposed[1,2].Thefrequen-cy method should performthe inverse Fourier trans-formation,so it is not more accurate than ti memethod to some degree.The method of characteris-ticsis based ontheti me domain met…
