By using dose-response functions and life functions to calculate the damage to the building materials and bicycles, the destructive action of acid deposition is quantified.

aterial damage function has been developed for calculating corrosion rate of specificmaterials and relevant service-life under different pollution levels on evaluation of economiclosses of material damage due to acid deposition.

The yield function and damage function of the unsaturated loess are established based on the principle of loess damage evaluation principle,the relationship between stable porous ratio and stable state of wholly-disturbed saturated clay,and the fact that inverse def.

A category of mathematical model for systems subjected to shock damage is developed, the shock damage function of the system is defined, and the mathematical expectation of system damage is given, so that the formula of system reliability is expressed generally.

Overview of damage index-based analytical method for collapse of frame structure;

Study on damage evolution of frame structure based on damage index;

Methods Inhistologic observation,the stomach mucosa damage index were measured.

Size effect of damage parameters of concrete structures;

The remaining life formula of the neoteric architecture,whose core is damage parameter,is established,in which the feature of the neoteric architecture has been considered and the latest research achievements of structure s remaining life are referred.

Theoretical formulas under simple state had been educed, including the relationship of self-vibration frequency and section damage coefficient, so that structural damage can be evaluated by measuring the model parameters of structure.
