By synthesizing theories of systems engineering, science of talent, talent assessment, performance appraisal and bibliometrics, the author analyzes the qualification structure and performance structure of theachers in military academies and sets up a basic structure and concrete appraisal indicator system of qualifications of technical specialty for teachers in colleges. The author puts forward new appraisal indicators such as "lecuring hours coefficient","republication coefficient","thesis of core journals coefficient" and "citation coefficient". Comparatively complete quantification approaches are invented by the author for working performance of teaching, researching and social service of teachers. Based on this, the author establishes an integrated method to generate the appraisal results. By the application of stadardized processing on the appraisal results and synthetization of weighted indexes, the author solves the addibility and comparability problems of differentiated appraisal results by category or dimensiok, and realizes the amalgamation and comprehensive appraisal of inflexible appraisalresults and flexible appraisal results, and probes into the testification methods of validity, consistency and sensitivity analysis for the indicators system.

In addition, some experience formulas for them are regressed. The third chapter establishes a unified S-N curve equation to calculate multi-axial fatigue ultimate strength of concrete considering both the effect of confinement and minimum/maximum stress ratio, based on the triaxial fatigue test data in this paper and the test results under uniaxial and biaxial fatigue loading in previous literatures. Moreover, the consistency of calculating condition fatigue ultimate strength with fatigue life distribution and initial ultimate strength distribution is analyzed.
