通过调整输入采样速率和输出数据速率的频率比(ratio of the frequency),可直接影响有效位数;只要增加每个输出结果的输入采样次数,有效位数也会增加,使得模拟数字转换器的有效分辨率因此提高。

The closer the ratio is to 100 percent, the lower the frequency of disk I/O, and therefore the less overhead of reading data.
命中率越接近 100%，磁盘 I/O 的频率就越低，因而读取数据的开销就越少。
The write-behind configuration should be tuned to best match your environment with regards to the ratio of write transactions, the same record update frequency, and database update latency.
write - behind的配置可以调整，以满足自己的运行环境，这其中包括写事务的比例，相同记录更新的频率，以及数据库的更新延迟。
The equivalent viscous damping ratio and the equivalent natural frequency are obtained by comparing the system with a purely linear, spring-mass-damper system of single freedom.
通过和单自由度线性弹簧-质量-阻尼系统进行比较，得到该带裂缝梁结构的等效自然频率和等效粘滞阻尼比。
