The.re.ults indicate. that the.disulfide.bonds almost cannot be.forme. corre.tly with the.common mobile.phase.by WAX. Howe.e., with the.ure. gradie.t e.ution and in the.pre.e.ce.of GSSG/ Cyst as the.ratio 1：6 in the.mobile.phase.e.ploye., the.disulfide.e.change.of re.uce./de.ature. insulin can be.acce.e.ate. re.ulting in forming the.corre.t thre. disulfide.bonds. The.prote.n re.olding e.ficie.cy of re.uce./de.ature. insulin can be.incre.se. from 3 % to 34%.

The.microscopic inhomoge.e.ty of crystal aggre.ate.has be.n take. into account with the.microstructure.made.up of a re.re.e.tative.aggre.ate.of single.crystal grains. Multi-scale.analysis is pe.forme. by coupling the.microscopic crystal plasticity with the.macroscopic continuum re.ponse.through the.pre.e.t homoge.ization proce.ure. The.macroscopic stre.s is de.ine. as the.volume.ave.age.of the.corre.ponding microscopic crystal aggre.ations, which simultane.usly satisfie. the.e.uation of motion in both micro- and macro-state.. The.propose. nume.ical imple.e.tation is base. on a finite.e.e.e.t discre.ization of the.macrocontinuum, which is locally couple. at e.ch Gaussian point with a finite.e.e.e.t discre.ization of the.attache. micro-structure. The.solution strate.y for the.macro-continuum and the.pointwise.ttache. micro-structure.is imple.e.te. by the.simultane.us e.ployme.t of dynamic e.plicit Fe.formulation.
