This paper took the roller of a new cotton picker as the example, drew its various parts and assemblyed overally in the three-dimensional mapping software environment of UG, imported the models into the virtual reality assembly platform by the interface between UG and VAPlatform, added the virtual hand and carried through the virtual assembly in the virtual scene based on the certain assembly restriction in UG. The paper realized the visualization of the assembly path, offered the foundation for the feasible assembly path, and finally obtained the reasonable assembly process, provided a set of reasonable operation guide for the workers to assemble the cotton pickers.

The growth of (Cd,Zn)Te (CZT) crystals and the improvement of the crystal quality are part of a research project towards experiments under microgravity using the Traveling Heater Method (THM). In order to determine the experimental parameters, we performed a detailed ground-based program. Three CZT crystals with a nominal Zn content of 10% were grown using THM from a Te-rich solution. The size and distribution of the Te inclusions were evaluated by transmission infrared microscopy (IR). From the three-dimensional mapping of the inclusions, we observed striation-like patterns in all of the crystals. The correlation between the growth parameters and the formation of these striations was explored and discussed. We found that the inclusion striations are related to periodic temperature variations.
