At 3 days, the adhesive cell balls continued to proliferate(about 50 cells), and the floating cells proliferated into cell balls(4 to 8 cells).
第3天贴壁的细胞球继续增殖（约50个细胞大小），漂浮的细胞则增殖成4～8个大小的细胞球；
2
At least one third doped region is between the first cell and the second cell, wherein the third doped region is floating.
至少一第三掺杂区域处于所述第一单元与所述第二单元之间，其中所述第三掺杂区域为浮动的。
3
To the electrical power system reliability request high situation, USES two group of accumulator cell parallel operations, the floating power supply way generally.
