刷新周期取决于的行数，必须刷新。
The refresh cycles depend on the number of rows that must be refreshed.
要调整刷新周期，请参阅更改刷新周期。
To adjust the interval, please see Changing the refresh interval.
刷新周期是指图中滚动并显示新的竖条的频率。
The refresh interval is how often the graph scrolls and shows a new bar.
然而，频繁的刷新周期可能对资源的利用产生负面的影响。
However, a more frequent refresh cycle can have a negative impact on resource utilization.
通常，数据延迟或数据传播依赖于数据整合过程的刷新周期。
Generally, the data latency or data currency is dependent on the refresh cycle of the data consolidation process.
刷新周期一般由一个叫DRAM控制器的外设完成。
The refresh cycles are usually performed by a peripheral called a DRAM controller.

因此这种模式无法将它们传播回数据源，并且将在目标的下一个刷新周期被覆盖。
As such they are not propagated back to the sources by this pattern and can be overwritten during the next refresh cycle of the target.
在整合过程的刷新周期之间，数据源中数据的更改越频繁，目标中的数据就会变得越陈旧。
The more frequently data in the sources changes between the refresh cycles of the consolidation process, the more stale the data becomes in the target.
图上的每个竖条表示一个刷新周期对应的一个值，刷新周期可以在一秒到数小时之间任意取值。
Each bar on the graph represents a value for one refresh interval, which can be anywhere from one second to many hours.
如果QApply已经在运行，那么需要告诉它新的刷新周期，因为它只在启动时读一次刷新周期。
If QApply is already running, it needs to be told about the new refresh interval since it is only read once at startup.
您可以使用Ajax在后台处理许多用户交互事件，然后更新页面的各个部分，而无需完整的门户刷新周期。
You could use Ajax to handle many of the user interaction events in the background, and then to update portions of the page, without requiring a full portal refresh cycle.
而且，你可以设置一个时间间隔偏差，其取值为0到1,440分钟(24小时)，可使刷新周期更随机。
In addition, you can set an interval offset, which further randomizes the refresh period to any value between 0 and 1,440 minutes (24 hours).
由于在信息被写到监视器表中之前，图中不能显示信息，所以刷新周期取决于QApply或QCapture写监视器信息的频率。
Since the graph cannot show information unless it has been written to the monitor tables, the refresh interval is governed by how often QApply or QCapture are writing monitor information.
