This method is mainly used for testing various material surface's small crack, its main drawback is that the equipment are often complex and high demanding for environment, which generally have a dedicated darkroom.
What the Magnetic Particle Testing Machine does automatically are complex magnetize the bar to be detected, feeding, clamping down materials and demagnetization and so on.

Flowing liquid metals are primary candidates for the spallation target material, due to the high power density deposited by the proton beam.
However, liquid metals can be corrosive towards containment materials of interest (austenitic steels and Fe-9Cr alloys)[1].

The initial planning, architectural design, material selection, site construction and the final usage and management, all directly affect the effect of energy saving.
In addition, the local rich natural materials and resources should be effectively used.
Fig.1 The library of Chinese academy of sciences Energy saving consideration in monomer building design Reasonable shape design.
Energy-saving building materials should be used to effectively reduce the heat transfer through the exterior-protected construction and the energy saving doors and Windows should be made use of to improve the air tightness of external window.
