Tear Breakup Dynamics: A Technique for Quantifying Tear Film Instability
ABSTRACTPurpose.The purpose of this study was to develop a novel, quantitative measurement of tear film breakup dynamics (TBUD) to study the phenomenon of tear breakup in dry eye and control subjects and its impact on dry eye symptoms.Methods.Ten control and 10 dry eye subjects completed the Dry Eye
The equipment vibration and noise,which is caused by a machine on the flexible foundation in engineering,is studied on dynamic model of multiple mountings isolation system.The dynamic transfer equations are deduced,which are composed of the machine,isolators and elastic foundation.From the point of view of energy transmission,the aim is to discover influence of different parameter of set,isolators stiffness and foundation stiffness so that reference is provided for industrial design parameters.
