接触问题

In addition, depending on the method of numerical simulation and theoretical analyses, some kinematic and geometric features of 0° involute—enveloping worm gear drive, such as meshing surface, first—type limit, second —type limit, worm surface, the numerical representation of contact line and bearing contact, are systematically studied. These relevant conclusions provide an important basis for the design and manufacture of new type worm gear set. As we predict, the method of numerical simulation has special effect in solving the question of complex conjugate surface.

Results The source of the greatest subjective pressure of the HIV infected mostly came from the problem of economy. In regard to the total scores of social health, coping style and social support, statistical significant differences were found between the infected group and the control group and between the family-member group and the control group. The scores of social resources, social contact and social support of the HIV infected were positively associated with that of the use of social support. The scores of social role's activity and social adaptation of the HIV infected were positively associated with that of positive coping style. The scores of social role's activity, social adaptation, social resources and social contact of the infector's family-members were positively associated with that of family-member's subjective. support.

结果 1HIV感染者及其家属的主观最大压力来源大都是经济问题。2在社会健康各维度、应对方式以及支持总分上，感染组、家属组与对照组之间的差异均有统计学意义。3HIV感染者的支持利用度的得分与社会资源和社会接触的得分、社会支持的得分正相关，积极应对的得分与角色活动、社会适应的得分正相关。4HIV感染者家属的主观支持的得分与角色活动和社会适应的得分、社会资源和社会接触的得分正相关，文化程度与社会支持的得分正相关。

The innovation of this thesis is: advanced a new method by adopting "three-ring method" to measure dynamic contact resistance of slip-ring, solved the lower measuring efficiency and inconvenience resulted in leads intertwist during the measurement of dynamic contact resistance of slip-ring.
