The concept of texture configuration entropy is introduced into the computer simulation on texture evolution of polycrystalline films.

Both the structural evolution of elemental powder during mechanical alloying and the effect of heat treatment on microstructure of as-milled powder were investigated by X-ray diffractometry(XRD),transmission electron microscopy(TEM) and scanning electron microscopy(SEM).

The structural evolution of Mo33Si66 element powders in the process of mechanical alloying and subsequent heat treatment was studied by X-ray diffractometer and transmission electron microscope.

The structural evolution of Fe-Al-Ti-B quaternary powder during mechanical alloying was studied.

The paper shows the structure evolution of bevel and hypoid gear generator as well as its working principles.

A lot of studies have been done in the fields of thermodynamics, microphase separation and structure evolution in polymer systems, which has become one of the most hot issues in c.

For the inspiration to future study, this paper cards and reviews the current study on direct investment on mainland by Taiwan businessmen, according to structure evolution, entrance model, management characteristics, construction of across-border net, investment effects and development trends.

Firstly, it forms four kinds of basic type of loose cogwheel straight line retarded machines by the axiom of mechanismic evolution, secondly, the machines were changed by the axiom of moveable change, achieving 16 kinds of basic type of loose cogwheel straight line retarded machines and 16 kinds of closed type of loose cogwheel straight line retarder.
