中文摘要：

作者从代数观念出发研究了Current的表示定理．对于完备不变Current，利用构建的极小三元组技巧，给出了一个类似的Radon-Nikodym定理．

英文摘要：

The authors study the representation theorem of current by using the view of algebra, The similar Radon-Nikodym theorem for completely invariant current is obtained by virtue of the constructing minimal triple.
