As a application of this theory, we discussed the interpolation problems in which the nodes are ununiform rectanglar grids in real space. We gave the lowest interpolation bases of nodes in rectanglar and sidestep-shaped area. Another application is for finite elements theory. We mainly discussed finite elements of Hermite-Birkhoff type interpolation and gave a new algorithms for a interpolation bases.

The theoreti cal results show that in Al-rich region of the ordered TiAl alloy,the surplus a toms of Al which occupy the lattices of Ti will decrease the energy of the syste m,in favour of the stability of γ-TiAl phase,while in the Ti-rich region, the surplus atoms of Ti which occupy the lattic of Al will increase the energy o f the system,which disfavors the stability of γ-TiAl phase,and favors the formation of new phase.

理论结果表明有序的γ-TiAl相在富 Al区，多余的Al原子占据Ti的格点后，系统能量降低，有利于γ-TiAl相的稳定性，而在富Ti区，多余的Ti原子占据Al的格点后，将使所有的Ti原子的能量增大，使系统能量升高，不利于γ-TiAl相的稳定性，而有利于新相的形成。

For many years, the Lattice QCD's researchers were working hard try to solve the difficulties in the theory, e.g. the doubling of fermion and the breaking of chiral symmetry.
