Abstract: An application of collagen peptide in the preparation of an allergen preparation auxiliary material. For an allergen preparation, the auxiliary material thereof does not contain biological macromolecules, but contains the collagen peptide, avoiding the risk of potential allergies caused by the introduction of an inactive substance protein. The allergen preparation containing no biological macromolecule auxiliary materials can be stored stably for three years at room temperature. For allergic patients, the allergen preparation is a highly effective, stable and safe drug.

Abstract: A method and device for simulating microstructure evolution of a material based on solution in an exponential time-difference format. The method includes: establishing a reaction rate theory model for substance defects, wherein the model is expressed with equations that comprise linear terms having coefficients characterized with matrixes; and iteratively solving the equations by using an exponential time-difference format, wherein during the iterative solving, the linear terms with exponential powers of the matrixes as the coefficients are integrated. Since a rate theory is not limited by spatial-temporal scales, the advantages of the rate theory can be significantly reflected when the microstructure evolution is simulated under a high damage dose condition; and then, the equations are solved by using the exponential time-difference format, with a solved result better in accuracy and higher in precision.
