The elapsed time for completing the task becomes a function of the partition size f(1,000,000) versus a function of the total number of records to process f(100,000,000).

完成这项任务所耗的时间变成为分区大小的函数 f(1,000,000)，而不再是要处理的总记录数的函数 f(100,000,000)。

A large opening (small f-stop number) gives you a very shallow DOF, and a small opening (big f-stop number) gives you a much deeper DOF.

一个大洞的开启(小f值)会带给你浅度景深，而一个小的开启(大f值)则会给你一个深度景深。

The Fibonacci numbers are an integer sequence where for a given number, the Fibonacci value can be calculated using: F(n) = F(n-1) + F(n-2).

Fibonacci 数列是一种整数序列，可以使用以下算式计算各个 Fibonacci 值：F(n) = F(n-1) + F(n-2)。
