Research on Methods to Fast Eliminate Singular Value in Irregular Initial Measured Displacement Serial

In order to analyze vary interval measured displacement serial, the fast and effectively method to eliminate singular value is build. Firstly, the singular value is initiatively judged and eliminated by logical analysis method, then uncertain filtering method is improved to fast eliminate singular value based on feature of measured displacement. Examples show the variation trend and measured value character of initial value can well be retained, and singular value of initial value can be effectively eliminated fast and simply while true signal (abnormal value) can be reserved effectively. So these treatment methods can provide with reliable analysis date for the successor research based on the dealt measured displacement.
