Transfer 2.0 mL of this solution to a 50-mL volumetric flsk, dilute with Buffer solution to volume, and mix.
移取2mL此溶液到50mL容量瓶中并用缓冲溶液定容至刻度，混匀。

Secondly, we expand the scope of detectable flow parameters by using image method in dilute phase flow regime, and achieve measurement of volume voidage.
其次，扩充了在稀相流动中，用图像法可检测到的流动参数内容，实现体积空隙率的检测。

Also, greater water volume helps dilute a river's chemical content.
