Black box theory

中文百科

黑箱 Black box

黑箱，指一个只知道输入输出关系而不知道内部结构的系统或设备。与之相反的是白箱。 例子有：

  1. 物理学/电子工业中,指未知内部结构，只露出若干接头的电路，如二端口网络；
  2. 计算机科学中，指内部工作方法不清楚的进程。（也许是闭源软件）
  3. 系统工程学中指一个系统只能根据其外部表征来推测其系统功能，而不能了解其内部详细构造。例如中医就是一个黑箱系统，尤其是经络结构。

Black box 黑箱

（重定向自Black box theory）
The open system theory is the foundation of black box theory. Both have focus on input and output flows, representing exchanges with the surroundings.
The observed hydrograph is a graphic of the response of a watershed (a blackbox) with its runoff (red) to an input of rainfall (blue).
When the observer can also do some stimulus (input), the relation with the black box is not only an observation, but an experiment.

In science, computing, and engineering, a black box is a device, system or object which can be viewed in terms of its inputs and outputs (or transfer characteristics), without any knowledge of its internal workings. Its implementation is "opaque" (black). Almost anything might be referred to as a black box: a transistor, algorithm, or the human brain.
