内容摘要：

In the era of Large Hadron Collider (LHC), plenty of new very precise measurements not just further verify the Standard model and increase the precision of physical parameters, but also provide a golden age for further determining the Parton Distribution Function(PDF). However, the large amount of new measurements slow down the pace of analysis of individual data and also the global analysis. We develop two programs to foresee the potential impact to PDF, the PDFsense and ePump. In the program of PDFsense, the "sensitivity" take the place of correlation cosine for predicting the potential impact to PDF. It also provide a visible way to see the potential impact on individual flavor of parton in x-Q plane. The ePump, the Error PDF Updating Method Package, implement the method of Hessian updating for foreseeing the predicted impact to PDF directly.
