摘　　要：在弱L-余拓扑空间中,引入弱紧集的概念,并且用滤子和网给出了弱紧性的等价刻画.证明了弱紧性在弱连续的L-值Zadeh型函数下是不变的.The concept of weakly-compact set is introduced into the weakly L - cotopology spaces. The concept of weakly compactness is defined and characterized in terms of nets and filters, It is shown that the weakly-compactness is invariant under the weakly continuous L - valued Zadeh function.
