In2O3 thin films were prepared on glass substrates by radio frequency magnetron sputtering. The structural, electrical and optical characteristics of In2O3 films were investigated by atomic force microscope, X-ray diffraction, X-ray photoelectron spectroscope, UV-Visible spectrophotometer and Hall effect measurements.

采用射频磁控溅射法在玻璃衬底上制备氧化铟薄膜，通过测试原子力显微镜、X射线衍射、X射线光电子谱、紫外可见分光光度计以及霍尔效应，研究了氧化铟薄膜的结构和光、电特性。

The system departs the data sampling module from the processing one by using wireless radio frequency communication, puts the sampling modules of pressure and temperature inside the tire, data processing module and the display alarm unit on the driving plate.

系统利用无线射频通信使数据采集模块和处理模块分离开，将压力和温度采集模块置于轮胎内部，数据处理模块及显示报警单元置于车内驾驶台上。

Results Total 78 cases were received 80 times of radio-frequency ablations through the guidance of CT.Reduced size of the pulmonary neoplasm and reduced chest CT number by 30~37 were founded in most cases(77.4%).

结果78例病人经CT引导行射频消融80例次，绝大多数病灶(77.4%)复查CT均有不同程度缩小或CT值下降30～37，疼痛等症状明显缓解。

There are various means to realize the communication link between FMU and ammeters, such as Ethernet and PLC, however they all have different limitation. We would take advantage of radio frequency in ISM channel to provide a better solution in the communication between FMU and ammeters.

集中器与电表之间的物理链路可以有很多选择，如以太网，电力载波线等，但它们都存在着一定的缺陷，所以我们采用了公用ISM频段的无线通信方式来实现集中器与电表之间的数据通信和采集，这种技术有很多优点，它无需布线、成本低、传输速度快、可靠性高。

Control theory of antenna array uses the range-barycenter formular which US Boing put forward in 1970s in radio frequency simulation. This method neglects the change of polarization that the array surface curvature causes and the spacing between the antenna elements, so big errors are made.

射频仿真暗室天线阵列的精度控制通常采用20世纪70年代美国波音公司提出的幅度重心公式，该表达式忽略了天线阵面弧度对三元组喇叭极化方式的影响，以及三元组天线单元间距对控制精度的影响，因此存在控制误差。

Similar to other kind of communication systems, the radio frequency modular of RSU in DSRC include many parts such ad antenna, duplexer, low noise amplifier, local oscillator, mixer, filter, modulator, demodulator, and so on. It's difficult to analyze every part in the system fully, so the emphasis is mainly on the parts designed and implemented for the RSU by myself.

和其它通信系统类似，专用短程通信系统路边单元的射频部分包含天线、双工滤波器、低噪声放大器、混频器、本振、滤波器、调制解调器等多个功能模块，论文中要完整地介绍和分析每一个功能模块是困难的，因此本文主要介绍自己亲自完成的部分。

Early identification techniques based on classical parameters such as: radio frequency, pulse width, pulse repetition interval.

早期的辐射源识别方法都是在常规参数层面上进行识别，比如载频、脉宽、重频等。

The service primary cognizance work is services the handset and the bare machine line board examination, software promotes, the data renewal and so on, I can use the air gun, the electric iron weld the electronic original component, uses the Oscilloscope match machine radio-frequency head and the baseband part survey, the use special data downloading match machine software promotion renews may read knows the electric circuit blueprint match machine breakdown to carry on the extrapolation, uses UFS-3 to process the machine, I already had 6 years work experience.

维修员主要负责的工作是维修手机与裸机线路板检测，软件升级，数据更新等，我会使用风枪、电烙铁来焊接电子原器件，使用示波器对手机射频部份和基带部份测量，使用特殊数据下载器对手机软件升级更新可读识电路图纸对手机故障进行推测，使用过UFS-3来处理机器，我已经有6年的工作经验了。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
