刚接触软件，想请问一下运行没有结果是为什么呢？ Clear["Global`*"];Subscript[q, r] = Q - (Subscript[p, r] - Subscript[p, e])/(1 - \[Theta]);Subscript[q, e] = (\[Theta] Subscript[p, r] - Subscript[p, e])/(\[Theta] (1 - \[Theta]));Subscript[\[Pi], m] = w Subscript[q, r] + Subscript[p, e] Subscript[q, e] - (c - Subscript[o, 2] l) (Subscript[q, r] + Subscript[q, e]); Subscript[\[Pi], r] = (Subscript[p, r] - w) Subscript[q, r] + Subscript[o, 1] l (Subscript[q, r] + Subscript[q, e]) - kl^2; FullSimplify[ Solve[D[Subscript[\[Pi], r], Subscript[p, r]] == 0, Subscript[p, r]]]
