For the different materials, it is necessary to make the appropriate adjustments.
But, theory has not been able to provide precise holetype design formula due to a variety of factors of the materials, over bending angle for the stress and strain.

Abstract.
Materials and Methods (1) Experimental material MSW was collected from Beijing transfer station in August, 2012.
Cumulative gas production means the amount of fuel gas produced by materials complete gasification which is the most basic material gasification indexes and can be roughly represent materials potential gasification.
Chinese Journal of environmental science, 2005, 25 (1): 34~38.
Journal of solar energy, 2001, 22 (3): 286~290.

The material quality of mc-Si wafers, as measured by the lifetime, varies with position in the cast ingot.
Finding ways to improve the material quality at the extrema of ingots is therefore of technological importance.
