Considering the influence of other loads and uncertain factors, the follows should be taken into account if the bridge erecting mode is continue to be used.(1) Strengthen beams of steel structure with orbits, especially second half part of the Bere Beam;(2) Altering the space between crossties and increasing the support in the mid of station weight beam both can enlarge the decentralization function of the load carrying on the trunk beam, but usually the latter way is more effective. When the latter way is chosen, the stiffness of the support should be diminished correspondingly. Furthermore, adjusting the height of the support would help a lot in dispersing load.

考虑到其它载荷的影响以及不可预测因素，如继续使用该类架桥方式，应做以下考虑：(1)增加钢架梁与轨道的支撑，特别是在贝雷梁的后半部分；(2)增大荷载作用在箱梁上的分散系数，可适当改变枕木间距，亦可在配重梁的中部增加支撑，后者效果会更有效，当考虑增加支撑时，同时要降低支撑的刚度，支撑如能简单地调整高度，将会对分散载荷起到非常大的帮助。

Properties of frontier orbital of xanthogen formates and ethoxycarbonyl thionocarbamates, including HOMO energy, shape of HOMO and atomic HOMO density, were calculated with quantum chemistry programs GW03 and FUJISTU CAChe. According to the results, the relationship between selectivity of such two kinds of collectors and their quantum chemical indices was investigated to discuss the feasibility of applying them in screening chalcopyrite collectors.
