Second, the conservative property of the semi-discrete spectral scheme is proved. And at last, the conservative property is used to obtain the priori estimate of approximate solution and the existence of global solution for Zakharov equations., authors=SUN Lu¹, ZHANG Fayong², ZHU Jie¹, CHEN Honghai¹, WANG Hongjiu¹, authorsList=SUN Lu;ZHANG Fayong;ZHU Jie;CHEN Honghai;WANG Hongjiu, authorCompany=1.
