The 1984 Edition of Zeng Gong Ji by Zhonghua Publishin g House is a comparatively complete collected works of Zeng Gong’s poetry and prose to date, but there are quite a few defects, which are generally in three categories: one is mis spelling, one is mis punctuating, and one is mis proofreading.

An Integral and Recursive Filtering Method for Truncation Error Minimization and Outlier Suppression;

Using Error Theorem to Reduce the Truncation Error Produced in Calculating the Velocity and Acceleration of Spacecraft;

The studying of a fusion approach to estimate and compensate the differential truncation error using tracking and telemeted data;

An especial structural model is obtained through corrected truncation errors of finite difference and the gray numerical arithmetic solving this kind model is given.

From the relation of spatial disturbing gravity and ground gravity data resolution as well as its scope, truncation errors are computed by dividing the gravity anomaly into frequency and resolution.

The research of error diagnosis model based on knowledge base in ITS

So, it is necessary to research and develop an approach for error diagnosis and correction with good expansibility that the working efficiency is high, and searching time is short.
