我们发现，当CPU不处理随机操作时，其对于 zipSeries服务器的平均使用时间下降大约 15％。
We found that, on average, CPU use time for the zipSeries server decreased by about 15% when it was not handling randomization.
对每项单独的操作，记录其时间，并在测试结束后计算其平均值。
The time is recorded for each individual operation and averaged at the end of the test run.
不过，我们最关心的是平均读取时间。在我们的基础测试中平均读取时间为 6.3MB/秒，而读操作的速度为 4.3 MB/秒左右。
The key element we are concerned with, though, is the average read time, and in our base testing we obtained 6.3 MB per second, with about 4.3 MB of that being read operations.
例如，一个15,000RPM驱动器的读操作需要大约3.5毫秒的平均寻道时间，写操作则需要大约4毫秒。
For example, a 15,000 RPM drive has an average seek time of approximately 3.5 milliseconds for reads and 4 milliseconds for writes.
为得到比较可靠的结果，我们多次执行导入操作和查询，对测量到的时间取平均值。
To achieve some reliable results, we executed the import operation and queries several times and averaged the measured times. The spatial operations are the following.
它给出了在一个时间窗口内所有的ActiveRecord操作，并且允许你使用一些标准对这些操作进行排序，例如总消耗时间、平均时间和吞吐时间等等。
It shows all the ActiveRecord operations for a selected time window and allows you to sort them using several metrics including total time consumed, average time, and throughput time.
循环缓冲区好处是：使共享资源的线程的等待时间减到最小，并使他们的平均操作速度相同。
Circular buffer benefits are: to make a thread of Shared resources to minimize the waiting time, make them the same as the average operating speed.
测定各量表的平均评分时间进行可操作性评定。
Acceptability was evaluated by average scale-assessing time. Results: 1.
实验考察了操作电压、电流强度、操作时间、处理溶液组分以及平均电流效率等因素对糖酸分离效果的影响。
Effects on separation effectiveness by such factors as current intensity, voltage, operation time, current efficiency and solution composition were studied.
