SRS Airbag and Air Conditioning System SRS?安全气囊和空调系统 短文A:SRS安全气囊 Airbags are known as Supplemental Restraint System (SRS) and has become more common in modern cars. The bag itself is made of a thin, nylon fabric, which is folded into the steering wheel or dashboard or, more recently, the seat or door. If airbags are fitted, the steering wheel cover and dashboard cover will usually have the words “airbag” or “SRS airbags” stamped into them. 安全气囊被称为辅助约束系统，现代的汽车已普遍使用。这个气囊本身是由一个薄的尼龙布做成的，折叠于方向盘或者仪表板，或者更近的地方，还有就是位于座椅或者车门之间。如果装有安全气囊，方向盘套和仪表板盖通常会包含单词“安全气囊”或者“SRS气囊”加盖 在上面。 The sensors detect impact and signal the airbag to inflate. At least two sensors must be active for the airbag to inflate. There are usually five sensors: two at the radiator support, one at the right-hand fender apron, one at the left-hand fender apron, and one at the cowl in the passage compartment (A few systems use only two sensors—one in front of the radiator and another in passenger compartment). There is an interlock between the sensors, so that two or more must work together to trigger the system. The airbag systems are designed to deploy in case of frontal collisions only. 在传感器检测信号的影响下，安全气囊充气，至少有两个传感器必须被激活，安全气囊才会充气。通常会有五个传感器：两个在散热器下，一个在右侧挡泥板周围，一个在左侧的挡泥板周围，同时在车厢通道罩（少数系统只有两个传感器，一个在散热器的前面，另一个在乘客座椅里面）。传感器之间有一个联锁，使两个或者两个以上必须共同作用下才会触发系统。安全气囊系统的设计只部署在正面相撞的情况。 The SRS airbag inflator contains a solid chemical gas generator. The solid chemicals are safely stored in a metal chamber inside the SRS airbag module. Each inflator is sealed to keep out moisture. SRS airbags are designed to deploy in moderate to majoy crashes only and should not deploy in minor crashes. 在SRS安全气囊充气机包含了坚实的化学气体发生器。固体化学品的安全储存存在SRS安全气囊模块金属腔里面。每个充气桶都是密封的，防止有水进入。SRS安全气囊为了只部署在中度至大崩溃，而不应部署在轻微的崩溃。 The following four steps shoe how the SRS airbag works: In an impact, sensors in the car detect the sudden deceleration. If the crash is severe enough, electricity flows to the inflator and causes ignition of the gas generator. The gas generat
