subscribe的意思？
一篇关于传感器的文章中，subscribe这个词以及他的派生词经常出现出现：
Running the experiment consists of subscribing to real time sensor data.......
Long running sensor subscriptions may benefit from implementing trigger or alarm mechanisms.
It takes few bits to subscribe to a sensor.....
在这里是什么意思啊？
参考答案:在这里是“获取”的意思，我恰巧读过，你看是不是这篇：
In a sensor experiment, the student usually can not specify any parameters although she may be able to select the particular sensor data that she wishes to receive. Running the experiment consists of subscribing to real time sensor data, usually presented in a graphical user interface such as a virtual strip chart. The system may provide options to filter the data or to transform it as well as to access archival data. Long running sensor subscriptions may benefit from implementing trigger or alarm mechanisms. Imagine an online seismometer that notifies a student of a seismic event through email or instant messaging. The detection of a seismic event that passed a specified threshold might trigger more frequent sampling or complementary data presentations.
在传感器实验中，试验者通常不会指定任何参数，虽然她能够选择她希望获得的精确的传感数据。进行这个实验在于获取实时的传感数据，这些数据通常由一个图形用户界面提供，比如说一个虚拟的带状记录纸。系统会提供选择以过滤数据，或者转换其格式，抑或是访问档案数据。长时期的传感数据获取可以得益于触发或者预警机制的实施。试想，一个在线用于通过电子邮件或者即时消息通知试验者地震事件的地震检波器。地震事件的检测数据，如果达到某一特定阀值的话，将会触发更多的高频样本或者补充数据。
