Listing 2 provides an example program written in PIR and executed by the Parrot VM.───清单2提供用PIR编写、由Parrot VM执行的示例程序。
PIR Sensors are used to detect the presence or occupancy of an object.───被动式红外传感器是用来检测对象的存在或占用。
For example, men who have a PIR of 350 earn 350% more than the poverty limit.───比如，PIR为350的人表示他们的收入是贫困线的350%。
And yet, as April began, the reopening of the Pir Mohammed School seemed imminent.───当四月开始，皮尔.穆罕默德学校的重开似乎有望了。
The dimensional stability of PU-PIR in heating status was better than that of the ordinary PU.───PU-PIR在受热状态下的尺寸稳定性优于常规聚氨酯。
These systems are often used with PIR sensors which can monitor movement in different areas of the home.───这些系统通常使用红外传感器，可以监测家庭运动在不同的地区。
After in-depth structure analysis, a passive infrared sensor ( PIR ) model was presented.───通过对系统的物理结构分析提出了一种被动式红外传感器模型。
This method is suitable for human detection systems of intelligent detection and identification based on PIR sensors.───该检测方法适用于基于PIR传感的人体移动的智能检测和识别系统。
