Moreover, preliminary explanation of the relation between lattice distortion and superconductivity has been made with the help of polarization theory and crystalfieldmodel.
同时，用极化理论和晶体场模型就畸变对超导性能的影响作了定性的解释。

The essence of our method is that, on the base of the crystalfieldmodel for point charge, the effect of molecule orbit is considered partly for the centrally symmetric field of coordination bodies.
这种方法的实质在于，在晶体场静止点荷模型基础上，考虑了诸配体等效中心对称场的部份分子轨道效应。

Equivalent thermal conductivity was introduced to simplify the structure of photonic crystal fiber, and then three dimensional temperature fieldmodel of photonic crystal fiber laser was established.
