At this rate the bubble pattern is most stable and creates the least amount of surface disturbance.

泡沫的图案表面，在这个流速是最稳定和使得表面扰动量最少的。

The liquid velocity is symmetric towards the wall. Values in (1) are 0.3 m/s for the discrete bubble pattern (where bubble rising velocities are 0.7 m/s).

液体的速率对墙体具有相称性，如图1中，当气泡呈离散式分布时为流体速度0.3米/秒，相应的气泡上升速率为0.7米/秒。

As yet gold's price chart does not display the classic bubble characteristic whereby the pace of increase seems to accelerate (although silver has been conforming to that pattern lately).

到目前为止，金价图标并没有显示经典的泡沫性质，因此其上涨步伐似乎还在加快(虽然银价不久前已经符合了这种模式)。
