在清单6中，从根据计数器作为初始步骤的动态sql快照数据中，您可以从总体成本、频率和每次调用成本角度列出最优sql语句。
From dynamic SQL snapshot data as the initial step based on the counters in Listing 6, you should be able to list out the top SQL statements in terms of total cost, frequency, and cost per invocation.
简单的特征频率计数器，但为什么不计数发生在实时？
Simple character frequency counter, but why won't the count happen in realtime?
该方法将GPS作为频率基准，间接得到了铷钟相对于与GPS的频差，避免了使用昂贵的高分辨计数器。
In the method, GPS is looked on as reference and the frequency difference between the Rb clock and GPS may be obtained indirectly, and the expensive high-resolution counter may not be needed.
