Embodiment Construction

[0041] The present invention provides a positron liquid filling system and filling method. In order to make the object, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific implementations described here are only used to explain the present invention, not to limit the present invention.

[0042] Below in conjunction with accompanying drawing, the technical scheme of invention is described in detail:

[0043] The invention provides a positron liquid infusion system and an infusion method, which can be used for three-dimensional imaging of the inner cavity structure and defects of industrial parts. The inner cavity of the part to be tested is a sealed structure, and its closed structure is determined by its own function, such as hydraulic system parts, which have only one input and one output; engine,...

Abstract

The invention discloses a positron liquid perfusion system and method. The positron liquid perfusion system comprises a part to be detected and a positron liquid perfusion pipeline system. The perfusion system is based on the perfusion system and includes: conducting liquid filling on the part to be detected according to specific needs of the part to be detected; and placing the part to be detected in a gamma photon detecting and imaging device and conducting the static or real-time three-dimensional imaging on the perfusion inner cavity structure. The positron liquid perfusion system and method is based on the positron annihilation principle, and can conduct the three-dimensional imaging on the complicated inner cavity structure of part and the inner wall micro-defects through the nuclide probe in the positron liquid.

Description

technical field [0001] The invention relates to the technical field of non-destructive testing, in particular to a testing method for performing three-dimensional imaging of complex inner cavity structures of parts through positron liquid perfusion. Background technique [0002] As early as 1928, British physicist Dirac P A M predicted that electrons have anti-electrons when studying the quantum theory of electrons. In 1932, American physicist Anderson CD discovered the existence of positrons in the cloud chamber photos of cosmic rays, marking the existence of human beings. Start working on positrons. Later, people noticed that the gamma photons generated after the annihilation of positrons can obtain information such as electronic structures, defects and phase transitions inside metal materials, semiconductor materials, non-metal materials, and condensed matter, which has attracted the attention of scientists and scholars around the world. , is also the reason for the rapi...
