Some primary beryl crystals are found in spodumene in zones Ⅲ and Ⅳ, and are enriched in Fe and Mg. The late secondary beryls with low contents of Cs2O are attributed to crystallization of pullucite and nanpingite. There is possibly a re-equilibrium between the late hydrothermal fluids and the Cs-rich beryl.

The umbilical cord blood solution, which the DMSO concentration is 1.0M, 1.5M and 1.75M,was confected. The solution was in equilibrium for 20 minutes. Then, the umbilical cord blood was completely immerged in liquid nitrogen for about 24 hours. Then, the umbilical cord blood was taken out and was warming in the thermostat water bath for 20 minutes. The fraction surviving of the umbilical cord blood was more than 80%.
