真正的流水灯：（1）第1，3，5，7个灯半亮，其余的全亮。



（2）第1个亮1/8,第2个亮2/8,第3个亮3/8,第4个亮4/8,第5个亮5/8,第6个亮6/8,第7个亮7/8,第8个全亮。



（3）来点小难的，所有的灯逐渐从暗到全亮，再由全亮到暗。



（4）最难的：8个灯从第一个开始依次渐亮，直到最后一个。再从最后一个起渐暗，直到第一个。如此循环往复。这才是真正的流水灯。

-The real light of the water: (1), paragraphs 1, 3, 5, 7 semi-bright lights, the rest of the bright. (2) a bright 1/8, 2 bright 2/8, 3 bright 3/8, 4 bright 4/8, 5 bright 5/8, 6 bright 6/8 7 bright 7/8, 8 full-bright. (3) to a little difficult, all the lights gradually from dark to full brightness, and then from full bright to dark. (4) the hardest: 8 light from the first start in turn gradually brighter, until the last one. From the last one from the dark, until the first. So on ad infinitum. This is true of light water.
