To their surprise, they found just the opposite of her result: Instead of moving with the flow, as Swartz had found, the cancer cells moved upstream.

令他们吃惊的是，他们只发现与她的研究发现相反的结果：癌细胞不是像施瓦茨所发现的那样沿着流动而迁移，它们是逆流迁移。

Instead, business users usually draw backward connections that direct a flow back to an activity further upstream as it is shown in the lower half of the figure.

业务用户通常绘制逆向连接来将流引回上游活动，如此图的下半部分所示。

Less than one-sixth of the total Mekong catchment is in China, but that upstream flow is crucial to neighbours during the dry season.

The potential for new large-scale upstream irrigation in the Mekong basin is limited by topography and so the annual flow of 400-500 billion cubic metres into the Delta is just not to going to disappear.

Two rival metering models used in large commercial buildings to track the flow of electricity as it moves through a building shows the difference between upstream and downstream applications in the smart-grid space.
