摘　　要：以一个广义协调元为例证明了非常规有限元与其常规对偶有限元刚度矩阵的谱等价性·　该结果对非常规有限元的区域分解并行算法研究有重要作用With a generalized conforming element as a typical example, the spectral equivalence of unconventional finite elements and their conventional relatives is proved. This result is very important for the construction of domain decomposition parallel algorithms for unconventional finite elements.
