To use the Across Worksheets option in the Fill submenu, you must have selected multiple sheets beforehand. Select adjacent or non-adjacent sheets in the same way you select cells. To select an adjacent range of worksheets click on the tab of the first sheet, then hold down the SHIFT key and click on the tab of the last sheet in the range. To select non-adjacent sheets, hold down the CONTROL key (Windows) or the COMMAND key (Macintosh) while selecting. When you choose Across Worksheets from the submenu, the Fill Across Worksheets dialog box (Figure 1-18) will appear you can choose to fill Contents, Formats or both. 

Where the same strength and exact container and closure system is used for three or more fill contents, the manufacturer may elect to place only the smallest and largest container size into the stability program (i.e., bracketing). The design of a protocol that incorporates bracketing assumes that the stability of the intermediate condition samples are represented by those at the extremes. In certain cases, data may be needed to demonstrate that all samples are properly represented by data collected for the extremes. 

The graphic below describes the permanent, stamped markings that are used on high-pressure gas cylinders commonly found in analytical laboratories. Note that individual jurisdictions and institutions have requirements for marking the cylinder contents as well. These requirements are in addition to the stamped markings, which pertain to the cylinder itself rather than to the fill contents.

The heat conduction of whiskers relies mainly on lattice vibration, namely phonon vibration thus thermal conductive performance is excellent, whereas the heat conduction of polymer materials depends mainly on internal vibration between atoms, which makes the thermal conductive performance poor. If whiskers are filled into polymers, they overlap with each other in a matrix and form pathways of heat conduction. Therefore the thermal conductivity of the composite will be greatly increased. Zhou found that low filling content can effectively improve the thermal conductivity performance of epoxy resin. When the whisker content is only 10%, the thermal conductivity of the material increased by 3 times compared with the pure matrix. Li et al. found that the thermal conductivity of PP filled with 30% zinc oxide whiskers increased by 55.9% over pure PP.

The width of the crystallization peak Is represented by AT = 7 0 X qy where 7 stands for the Initial temperature of the cooling curve deviating from the baseline when crystallization begins stands for the temperature when the cooling curve overlaps with the baseline, that Is, when crystallization ends. The results are listed In Table 6.1. 7 of pure PP Is 129°C and decreases with an Increase of whisker filling content. 

As can be seen from the AT calculation results in Table 6.1, AT of pure PP is 26.9 C AT increases to 29.9°C after filling with 5% whiskers, and then quickly declines to 24.6°C when the filling content is 10%. After that, AT changes little as the amount of filled whiskers continues to increase, indicating that the crystallization peak of PP widens when filled with a small amount of calcium carbonate whiskers, and the crystallization peak of PP narrows with increasing whisker content. 

As can be seen from Table 6.5, with the increase of calcium carbonate whiskers, the flexural strengths of the composites increase first and then decrease. When the whisker filling content is 5%-10%, the bending stress of the composite material increases 11.5% over that of pure PP. In addition, the bending fracture strains of composite materials filled with whiskers... 

As can be seen from Table 6.8, at 5% thermal weight loss, the thermal decomposition temperatures of composites increase significantly with increasing filling content of calcium carbonate whiskers. The largest thermal decomposition temperature reached is 409.5°C at 15% filling content, indicating that the thermal decomposition temperature of PP material increases and thermal stability is improved with the addition of calcium carbonate whiskers.
