The Confirming of Optic Fibrous Sensor Supervising Concrete-facing Dam Structural Cricking
监测砼面板坝结构缝的光纤传感器率定

In order to confirm the displacement of optic fibre sensor,the author has set up the non-linear modal base.Nine kinds of modeling methods in the whole increment predicting & correcting model parameter are introduced.And weight formulas are directed such as the time-distance weight,velocity weightand vector weight when inserted. the non-linear model regression analysingsoftware Have been developed with VB.By calculating the instance, the precision of curve of confirming has been improved.
