查询词典 control panel

Firstly, the conception of networked control systems, introduction and content of networked control systems theory are introduced. Secondly, the network induced time delays of different topology structure are analyzed and then the corresponding plants are modeled. Based on the above, a compensation scheme for the transmitting time delay from controller to actuator is developed. And also a sliding mode controller that makes the system robust is designed.

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。

Although translator has turned from being a crystal ball by which the original culture can unrestrainedly penetrate to another crystal ball by which the target culture can freely traverse, the translator's personal embodiment, in the process of cognitive act, are still absent in translation studies. Translators are still subjects without body or simply disembodied subjects.
