Neutralized and light-shorted tones are the two main changes of the"stressed-unstressed"bi-syllabic tone sandhi in Shanxi province,which has five patterns.

In this paper, the significances of military equipment's light weight and the properties of some frequently used magnesium alloys are generalized.

This paper briefly introduces the features of the cool punch process and the main mechanical properties and processing performances of the commonly used light alloy materials,which provide the basis for selecting the suitable materials to satisfy the light weight requirement of the parts.

This research indicates that the inequable thickness of the top and bottom panels can improve the stress and stiffness of light weight sandwich struc.

Application of topology optimization to light-weight design of single cylinder engine;

Considering light-weight and safety,and combining integrations of both the probability density and the function density,the no-conservative fuzzy reliability design formulas about overhead traveling crane girder that deflection,allowed deflection,geometry dimension of component etc.

The key elements of light-weight design of two-dimensional scan pointing mirror in the space remote sensor are discussed in this paper.
