我使用构造器来初始化参数，并执行任意必要的设置(例如载入流库)。

I use the constructor to initialize the arguments and perform any required setup (such as loading the streams library).

这个参数设置在 map/reduce 任务中同时合并的输入流（文件）数量。

This parameter sets the number of input streams (files) to be merged at once in both map and reduce tasks.

在理想线性模型的基础上，研究了输入流量对液压凿岩机冲击机构工作参数的影响，得到了一组简明公式。

On the basis of theoretical linear model, the paper studies the influence of input flow on operating parameters of shock mechanism for hydraulic rock drill, and a series of brief formulae are derived.
