A few kinds of schemes of segmented mirrors are put forward in this paper. Under the condition of minimization of the residual error in fitting the desired wavefront, a series of formulas are induced, which are used to compute the parameters of the schemes. From the ability of compensation for atmospheric wavefront point of view, the schemes are evaluated. By computer, some important conclusions are obtained, which are the bases of making segmented mirros.
