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。
