可以这么理解
（怎么看着就像lipo2000的说明……）

能不能详细的解释下这个词啊

In cell culture biology, confluency refers to the coverage or proliferation that the cells are allowed over or throughout the culture medium. For example a confluency of 40-60% will mean that there may be little or no restriction to the growth of the cells in/on the medium and they can be assumed to be in a growth phase.

This observation is often related to the color of the media supporting the cells (i.e. rate of consumption) and the number of dead, floating cells that have not necessarily attached to the plate.

灵格斯词霸是个好东西……，

虽然有点懵懂，还是谢谢

应该是指贴附型细胞附着在细胞培养瓶上漫延扩散分裂增殖直至铺满整个培养瓶底部，此时称作confluency，中文叫融合状态。

cells or groups of cells, grown in culture on (so-called) solid
medium, have multiplied to cover the surface of the medium com-
pletely but without overlying each other. —confluent adj.
