This article elaborates upon the importance of the political and ideological work on the trainees in cadre schools in the new era.

Determination of multi-elements in superalloy by glow discharge mass spectrometry and interference correction;

Some important methods are researched and demonstrated, including numerical calculation, autogeneration and compling of G-code, simulating verify, interpolation and interfere calibration of cutter path.

Based on the analysis of workspace of PMT, a new mathematical model of workspace is built and the parameterized calculation is realized, which increases the efficiency of interfere calibration.
