By applying assumption of internal energy, i.e. , a set of reduced magnetohydro-dynamic equations are obtained for large aspect ratio, high tokamaks. These equations in-clude all terms of the same or der as the toroidal effect and only involve three variables, namely the ?ux, stream function and internal energy. %K Magnetohydrodynamics %K Aspect Ratio %K Viscosity %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=1368
