针对压制干扰和质心干扰的特点，分别建立了噪声干扰模型、信号功率衰减模型和质心干扰模型。
To counter the characteristic of suppress jamming and center of mass jamming, this paper establishes the models of noise jamming, signal power attenuation and center of mass jamming.
该光纤耦合模块连续工作500小时没有发现明显的功率衰减，并且输出功率经温度循环和振动冲击后具有较好的稳定性。
The output power is very stable after the temperature cycling and vibration test. No apparent power decrease has been observed as the device working continuously for 500 h.
与手机的距离增加后，功率(以及用户射频辐射接触量)迅速衰减。
The power (and hence the radiofrequency exposure to a user) falls off rapidly with increasing distance from the handset.
