No matter these parameter are wind- driven generation set is to be in meshy condition to still take off meshy condition to be monitored, use at judging status of the start condition of wind- driven generation set, job and breakdown situation, the power of have rendered great service that still is used at statistical wind-force generation set, without result power and total electricenergy production.

这一些系数不管力量发电机组是处在并网态势还是脱网态势都被检测，用在判定力量发电机组的起动因素、工作态势及毛病境況，还用在统算力量发电机组的有功码率、无功码率和总发电量。

Mobile phone RF system consists mainly of transceivers, power amplifier and antenna switch. PA might be set in the Front-End-Module or FEM. In 2G, the cost of RF system was only about US $1.5, while In 3G, the cost was increased to between US$6.0 and US$8.0, and the cost will further increased to about US$8.0 to US$10.0 in 4G, obviously, FR system had the highest cost growth during the upgrading of mobile phones.

手机射频系统有三个主要零组件，收发器、功率放大器（Power Amplifier，下简称PA）和天线开关，有时PA包含在前端模块（Front-End-Module，简称FEM）。2G时代的射频系统只占大约1.5美元的成本，3G时代则占大约6-8美元的成本，4G时代则占大约8-10美元的成本，也是手机升级换代成本增加最多的部分。

Button D is the power and timing key : When plug in the power, the green light on and the machine will be in standby mode, press one time is on and default timing as an hour, and press twice up to two hours, the third time is three hours, followed by cycle, If you want to turn it off,just long press it and last for 2 seconds,the machine is shut down and the returned to the standby mode,if you want to stop here just power take off.
