Abstract

A reflection-diffraction-deformation flaw detection method employs a transverse wave oblique probe. When an ultrasonic transverse wave encounters a defect during propagation, a reflected wave, a diffracted wave, and a deformed wave are generated. Through a comprehensive analysis of these waves, the presence or absence of the defect is determined by the reflected wave having reflection characteristics and the diffracted wave having the diffraction characteristics. The shape and size of the defect are determined by the deformed wave having deformation characteristics, namely the deformed surface wave generated at the endpoints of the defect which propagates on the defect surface. Furthermore, by the combination of paths trailed by the deformed surface wave, the deformed transverse wave, and the deformed longitudinal wave that are generated by the defect as well as that trailed by the transmit transverse wave, causes of all those waves in the screen can be revealed.

Abstract

The invention provides a shear wave oblique probe reflected/diffracted/deformed wave detection method. When an ultrasonic shear wave is propagated and encounters a flaw, reflected, diffracted, and deformed waves are generated; comprehensive analysis is performed on these waves, and it is determined, according to reflection features of the reflected waves and diffraction features of the diffracted waves, whether a flaw exists; the shape and size of the flaw is obtained according to a deformed surface wave generated at a flaw end point; by combining propagation paths of the deformed surface wave, the deformed shear wave, the deformed longitudinal wave and the transmitted shear wave generated by the flaw, the causes of all the waves displayed on a screen are revealed, so as to determine a basis for determining an angle or direction of a flaw, thereby accurately positioning flaws, performing quantitative and qualitative analysis, and displaying in three dimensions the actual flaw shape by using A-scan ultrasonic techniques.

Abstract

The invention discloses a method of real-time VOIP call, characterized by comprising the following steps: a) a user dials a landline phone and establishes a connection with a service terminal; b) the service terminal resolves a further dialing of the user, corresponds dialing information with an addressing address stored in the service terminal of the calling user, wherein the addressing address comprise a destination user name, a separator and a destination address; c) the service terminal of the calling user resolves information of the destination user name and sends it to a service terminal of the destination address; d) the service terminal of the destination address resolves the received information of the destination user name, and finds the information of the destination user name stored in the service terminal of the destination address, and then the service terminal of the destination address further finds a phone number of the destination user internally stored in the service terminal of the destination address; e) the service terminal of the destination address initiates a call request to the destination user; f) a calling connection is established. This method can achieve video conference and fax in the same way as the existing internet phone, and moreover, it is completely free of charge.
