Introduction The introduction of an external field, such as a magnetic field, to heat treatments of conventional materials, has originated much attention in hope of realizing microstructural modifications and thus properties improvement.
Magnetic field, especially high magnetic field, as clean, powerful and non-contacting energy, has received much attention in materials research area, as it can act on atomic behaviours, affect such as atom arrangement, matching and migration and hence exert powerful influence on microstructures and properties of materials.
Therefore, magnetic field processing appears to be actually a new, suitable and effective tool for the structural and functional control of materials.
Polar figures show a strong presence of a textures close to Goss ({110}<001> and a <111>//ND fiber that is a typical recrystallization fiber for bcc materials.

Under the condition that the competition evolves from single enterprise to supply chain, China's food industry must rely on their industry characters and trends to broad the management vision from suppliers of agricultural materials to the wholesale and retail enterprises, logistics distribution companies and the end-users at last.
The microbial invasion to raw materials may result that the safe quality time can not meet the expected shelf life of final consumers.

There are a large number of materials of piezoelectric effect, materials used for manufacturing piezoelectric sensors at present are divided into three categories: piezoelectric crystal (quartz crystal most commonly used), piezoelectric ceramic (lead zirconium titanate PZT and barium titanate BaTiO3 commonly used) and new piezoelectric materials (PVDF commonly used ).
Disadvantages: small piezoelectric constant and low sensitivity compared with the piezoelectric ceramic materials, material price expensive.
New piezoelectric materials basically include two kinds.
Table 1 shows the comparison of some properties of several commonly used piezoelectric materials.
