Introduction The layered structure of BSCCO superconductor grains makes it possible for people to get Bi-system wire rods and strips with good crystal orientation by using mechanical deformation and heat treatment, which is also the method of placing Bi(Pb)-Sr-Ca-Cu-O powder into a metal tube (Ag or Ag alloy) for processing and heat treatment.
When the temperature continues to rise to 510˚C(3#), the Bi-2212 phase and Bi-2201 phase are mixed apparently and the main peak of Bi-2201 becomes intense, indicating that such drying temperature makes the surface more uniform and smooth, conducive to the generation of the structure with excellent directivity by Bi-2201.

Acting as a coalgulant, zoogloea is the structure and function core of activated sludge.
To improve treatment load and removal rate of pollutant, immobilization technologies of activated sludge were developed to concentrate free bacteria in a fixed small space through chemistry or physical methods [7, 8].
Moreover, net structure of immobilized pellets was weakened by the mechanical confliction with wastewater.
