利用线性算子半群理论和抽象锥上的不动点定理，在合适的条件下建立了偏序rnBanach空间中半线性发展方程全局正解的存在性结果.%This paper is concemed with the existence of positive solutions of abstract semilinear evolution equations. Under the suitable conditions, the positive solutions are obtained by combining the theory of semigroups and the fixed-point theorem in abstract cones.
