In this paper , we principally expound the fundamental theory of equation of state , theoretical models on equation of state of solids , basis of approximation , and applicable semi - empirical , semi - theoretical equation of state of solids 本论文论述了物态方程的基本理论,固体物态方程建立的理论模型、近似基础,和具有实用价值的半经验、半理论的唯象固体态方程等。
In mathematics, the theory of equations comprises a major part of traditional algebra. Topics include polynomials, algebraic equations, separation of roots including Sturm's theorem, approximation of roots, and the application of matrices and determinants to the solving of equations.
