Percutaneous radiofrequency ablation(PRFA) is a newly developed technique in treating tumors, especially the therapy of PRFA is staying in a beginning state and many problems hasn t been clarified such as biological mechanism, pathophysiological changes and safety.

RFID is one of the automatic equipment identification,which develops rapidly recently.

The paper introduces the features of the forklift high-rack warehouse,analyzes its application mode,discusses its realizing methods and puts forward the informatizational solution for forklift high-rack warehouse based on the application of barcode and RFID in logistics field.

In this dissertation,the major work completed including:(1)Presenting the Working Principle,function and features of RFID,and application of RFID at China and abroad;based on all these factors,applies RFID to Personnel Positioning System Underground Mines.

Software s Design and Implementation of Highway ETC System Based on Radio Frequency Technology;

The paper introduces a RFID radio frequency identification system,which adopts radio frequency technology and fulfills automatic identification and inquiry of vehicle license plate to achieve an intelligent management of mobile vehicles through reading internal chip message of the only ID.

The RF technology develops quickly and has more application fields.

A wireless control network based on radio-frequency technology is designed to satisfy actual control needs.

Compared with water extraction,microwave-assisted extraction and ultrasound extraction,radio-frequency technology was characteristic of short time and high quality.
