[求助] MALAB中非线性微分方程 结果是Root0f()，求高手指点。小弟感激涕零

sd=1;Ti=1;Tc1=1;Tc2=1;To=1; x=dsolve('Dx-0.11826*sd-2700*(abs(x-Ti)/52.985)^0.25*1.323/x*log(17.27*x/(x+273.16))-3*abs(x-Ti)^0.33*(x-Ti)- d*((Tc1+273.16)^4-(x+273.16)^4)/1.9476- d*((Tc2+273.16)^4-(x+273.16)^4)/1.9476-0.171108*((x+273.16)^4-(To+273.16)^4)- 7.2*(x-Ts)=0'); subs(x); 朋友们，求帮助啊。。答案是Root0f什么的啊。怎么变为数字啊。小弟实在搞不出来啊。好几天彻夜难眠。导师催得紧。心里好难受。求高手好心人帮忙 1.jpg [ Last edited by 沙漠oo飞鹰 on 2013-4-18 at 16:16 ]
