The paper totally analyzes the building process of quality management system for armored equipment maintenance, taking WuLi-ShiLi-RenLi (WSR) as an instructing mode on high level for quality management and taking Lean Six Sigma (LSS) as an effective quality improvement and control method. Firstly, integration of WSR and LSS is analyzed. Then WuLi of building process from contents and processing methods is analyzed. ShiLi of building process through three phases as setting goals, putting forward concept, and carrying out concept, is provided. And RenLi of building process from smoothing relation, harmonizing interest, personnel management and training, and quality culture is given. Lastly DEA method is applied to evaluate the running efficiency of the system.

An advanced Dyson spectrometer has been presented for broadband stigmatic imaging. The spectrometer, with large enough axial spaces and lateral separation among the slit, the imaging plane, and the hemispherical lens, is composed of a thin hemispherical lens and two spherical lenses in the same material, and a reflection concave grating. The new spectrometer design maintains excellent optical performances and decreases inherent stray light of the concentric spectrometer with a high numerical aperture, which owns better engineering applicability.
