The nonlinear model of electro-hydraulic servo system is discussed, which makes the system's nonlinear model precise linearization. The influence of the spring stiffness, moment of inertia and viscous coefficient, servo valve preliminary open volume on robustness is discussed.
The quartz crystal micro balances (QCM) principle is simply introduces. LEM model can accurately describe TSM sensors with surface the load, instead of complicated TLM model. The configuration of sensor has pure quality load, liquid load in fluid Newton system, the sticky elastic thin film, and viscoelastic membrane plus half infinite liquid. Two kinds of material properties model prediction deviate with no more than 3% error. The rule of Judging TLM to be the LEM is Zl/Zq<0.1
The relationship between small enterprise management innovation and competitiveness is discussed. From the management idea, management system, management strategy, management organization and management culture innovation the small enterprises competitiveness is enhanced. The management innovation is the foundation of the competitiveness.
Strain rate, the control of the specimens’ damage, oscillation, and the response deformation are studied. The reliability of the special material LY12CZ specimen in the strain rate machine is tested. The experiment problem is solved by extending the strengthened piece. The strain rate of one-way GFRP loading experiment is also studied
The catalytic distillation synthesis of Dimethyl maleate CP by methanol and maleic acid is studied under the application of strong acid cation type catalyst in chemical engineering.. The sulfonic resin catalyst is chosen. The reaction of methanol and maleic acid is single one, while that of mono-methyl fumarate chloride and methanol is the reversible reaction balance. The pilot of catalytic distillation synthesis of Dimethyl maleate CP is issued. The best condition for synthesis is proposed
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
