[问题] 向高手求救！maple解中rootof解的转化问题！

[hanjiaojie]

通过maple算出来的结果居然是这样的：
RootOf((-4*N*ci^2*delta^2*theta*gamma^3+4*N*ci^2*delta^2*theta^2*gamma^3+2*U*gamma^6+ci*gamma^4-2*alpha*gamma^6+ci*delta^2*theta^2*gamma^4-2*ci*gamma^4*theta+ci*theta^2*gamma^4)*_Z^6-2*U+2*alpha+(ci*theta^2*delta^2+ci*theta^2+6*U*gamma^2+ci-2*ci*theta-6*alpha*gamma^2)*_Z^2+(-2*ci^2*N*theta^2*delta^3+4*delta*ci^2*N*theta-2*delta*ci^2*N*theta^2-2*delta*ci^2*N-8*delta*ci*theta^2*gamma+8*delta*ci*theta*gamma)*_Z^3+(6*ci*theta^2*gamma^2*delta^2-12*ci^2*delta^2*N*theta*gamma+12*ci^2*delta^2*N*theta^2*gamma+6*ci*theta^2*gamma^2+6*alpha*gamma^4-12*ci*gamma^2*theta+6*ci*gamma^2-6*U*gamma^4)*_Z^4+(-6*ci^2*N*theta^2*gamma^2*delta^3-6*delta*ci^2*N*gamma^2-6*delta*ci^2*N*theta^2*gamma^2+12*delta*ci^2*N*theta*gamma^2-8*delta*ci*theta^2*gamma^3+8*delta*ci*theta*gamma^3)*_Z^5, label = _L2)*delta*ci

请问下大家有哪位高手晓得这个解怎么转化成一般形式不？万分感激
