原创 OES OEM and AM

今天一个朋友发短信问我，AM是什么意思？ 

我的第一反应是：上午       before noon

                                  调幅  Amplitude Modulation

然后我问他，是不是还有FM啊？

这兄弟告诉我，与OEM相对的，汽车界的。

想了想，OEM是前装市场，Original Equipment Manufacture(原始设备制造商)

那AM应该是售后的吧，就告诉他是后装相关的，但不确定是什么的缩写。就让他确定下是不是after manufacturing。

晚上回来核实了一下，其实不是，是aftermarket。

另：原廠零件(OES, Original  Equipment Service) 及非原廠廠零件(AM, After Market)

 

维基上的解释如下：

Aftermarket (automotive), the addition of non-factory parts, accessories and upgrades to a motor vehicle.
After-market (general), any market where customers who buy one product or service are likely to buy a related, follow-on product. For example, customers who install a software package will constitute an after-market for software support services.
Aftermarket (finance) or Secondary market is the financial market for trading of securities that have already been issued.
