The analysis focused on the constant center frequency, so you can clearly see the characteristics of defect signals. References: [1] JIANXiaoming,[link widoczny dla zalogowanych], SONGWeiai, YANGLu.

From government departments, non-destructive testing industry, leading universities, renowned experts and professional technical staff of nearly five hundred people attended the forum. Forum based in China, the radiation from overseas to keep abreast of advanced technology, and development in the competition for the purpose of the initiative to strengthen cooperation in international and domestic exchanges, and promote the development of NDT technology in China, improve and enhance the competitiveness of enterprises for the purpose of selection of the latest international NDT research, advanced technology and equipment for the propaganda content. For industry collaboration. New technology, new product applications and sales promotion materials and equipment to provide a development platform. The Forum attracted well-known domestic and foreign non-destructive testing industry, research institutions, equipment manufacturers and users of nearly 4O home. Preaching topics are guided wave testing technique, ultrasonic TOFD / phased array inspection technology, ray digital imaging technology, eddy current testing technology, and other non-destructive testing of new technology research and application,[link widoczny dla zalogowanych], made from Chinese and foreign experts 3O 3O field project report. Wonderful lectures by experts blown away by the delegates. Will gallery features the latest in today's international non-destructive testing equipment, so visitors will want to return profitable. NDT Forum Far East the successful convening of the new technology will greatly reduce our non-destructive testing technology with the international advanced level, non-destructive testing on the development of China play a positive role in promoting. f Jiangsu Province Special Equipment Safety Supervision Inspection Institute Xu Jianqin) 2007 Vol 29 No. 6 321OOOOOOOOOOO5555O0O eleven ll1> base \ Tour Kennedy
