摘要：Based on an appropriate Lyapunov function,this paper analyzes the design of a delay-dependent robust H_(∞)state feedback control,with a focus on a class of non-linear uncertainty linear time-delay systems with input delay using linear matrix *** the condition that the nonlinear uncertain functions are gain bounded,a sufficient condition dependent on the delays of the state and input is presented for the existence of H_(∞)*** proposed controller not only stabilized closed-loop uncertain systems but also guaranteed a prescribed H_(∞)norm bound of closed-loop transfer matrix from the disturbance to controlled *** solving a linear matrix inequation,we can obtain the robust H_(∞)*** example is given to show the effectiveness of the proposed method.

摘要：文章通过分析高校技术成果转移转化工作对知识产权信息服务的需求,探究我国高校图书馆知识产权信息服务模式,围绕知识产权“创造—保护—运用—管理”4个关键阶段,构建嵌入专利转化全流程的建制化服务体系。深圳大学图书馆构建的面向高校技术成果转移转化的知识产权信息服务体系,既能有效完善高校知识产权信息服务范畴,推动图书馆信息服务转型,又能助力高校打破技术成果转化率低的困境,其服务经验可为其他高校图书馆提供参考借鉴。

摘要：农业开发公司电网存在设备陈旧、运行能力不足、线路导线载流量低等安全隐患问题，通过合理、经济地选择电气设备，因地制宜地采用新技术，获得了良好的节电效果和运行效果。简要介绍了农业开发公司电网存在的问题，较为详细地论述了安全隐患治理采用的创新技术，具体阐述了农业开发公司下属单位洮儿河农场、华侨农场、两万亩农场的电网安全隐患治理内容，并给出了治理效果。
