symmetric part

The central control room and workshop office are of East-West symmetric arrangement, the workshop office is located at the west part of the building, and the central control room is located at the east part of it, which are closely linked and interdependent.

中央控制与车间办公成东西对称布置，车间办公室位于该建筑的西部，中央控制室位于该建筑的东部，既相互独立又紧密联系。

The zeroth-order nuclear potential is taken tobe Woods-Saxon potential. The non-spherical symmetric part V_1 of the nuclear potential induced by the vibration of the target nucleus is considered as a perturbation.

考虑了核力势和库仑势，零级近似核力势取为Woods-Saxon势，由靶核振动引起的核力势的非球对称部分V1作为微扰。
