协调元、非协调元、杂交元

已知杂交元可以看作是非协调元,是否每一个非协调元均可作为杂交元的特例?容易明白,许多协调元和非协调元不能作为1]中提出的杂交元的特例.例如,1]中例 6的Wilson矩形非协调元就是如此.本文要拓广1]中提出的杂交元的抽象框架.使许多协调元和非协调元都能作为杂交元来处理.从而不但能得到未知量的近似值,而且能同时

CONFORMING,NONCONFORMING AND HYBRID ELEMENTS

The hybrid element may be regarded as a nonconforming element. But, the nonconfor-ming Wilson's element can not be regarded as a special example of the hybrid element byabstract frame in 1] (see 1], example 6). In this paper the abstract frame proposed in 1]is generalized. Thus, many conforming and nonconforming elements may be considered aspecial example of the hybrid element by abstract frame.
