The structure characteristics of ID precision uhrathin monoerystaUine silicon section cutting machine-tool spindle with force-monitoring bearings functioning as force measuring sensors were detected with the new Hilbert theory based signal-wave envelope detection method, presented to replace the conventional hardware device in order to ensure that the signal is measured online with high fidelity.According to the probability of anomalous incidents in the cutting process, a mathematical recognition model has been designed and verified on an STC-22ID machine. 相似文献

党的十八大和十八届三中全会确立了"五位一体"国家战略和推进生态文明制度建设的新要求.强化环保智库支撑和服务功能,为改善环境质量,科学制定决策,创新生态文明机制建设,推动环保管理转型,是落实上述要求的重要措施.美国、德国等国家环保智库高度发达,在探索环境政策、创新环境技术、引导公众参与等方面发挥重要作用,值得我国借鉴.相比而言,我国环保智库建设尚处于初级阶段.该文建议针对我国的自身特征与发展需要,从原则与目标、发展与架构、参与和运行机制等方面,强化并完善有中国特色的环保智库系统建设,使其为环保决策和制度创新提供强大的科学支撑. 相似文献
