It mainly distribute to the realization of the circulation of materials in a specific geographical area.
The main features of the regional logistics are as follows: Logistics information exchanging frequently and demand diversification The area of the industry cluster assembles a large number of enterprises, these enterprises demand frequent material flow either in internal production or external sales, as a result the services of regional logistics become more and more specialization and diversification.
To the enterprise, not only the material flow related the production such as the purchase and supply of raw materials but also the sales logistics are all entirely entrusted to logistics enterprises.

Introduction Nondestructive testing is used as a general name given to all test methods which permit testing or inspection of material without impairing its future usefulness.
At present, nondestructive testing technology has been widely applied to many areas, such as medical testing, survey the sea, machines, materials, high pressure vessel, aerospace field and huge bridge, etc.
To identify the internal defects accurately, the ultrasonic detection technique is widely used, with the advantages of detecting the materials and characterizing their properties without causing any damage, while remaining high speed, sensitivity, and deep effective.
