借助Clifford半群序和理论，根据外层算子G1是否为一致模的分类标准，提出了两种n-一致模的构造方法。基于这些构造方法,可构造许多新的n-一致模。作为应用，证明了相关文献中具有连续基础算子的n-一致模的所有分解定理的逆命题都成立。

By means of Cliffords ordinal sum theory,according to the classification criteria of whether the outer operator G1 is a uninorm, the other two kinds of methods to constructing a new n-uninorm are given. Based on these methods, there are a number of new n-uninorms. Moreover, as an application, it is proved that the converse propositions of all decomposed theorems hold for all n-uninorms with continuous underlying functions in the relevant references.
