摘要
运用2种方法研究一类时滞能源价格方程在平衡点处的振动性,运用反证法,利用时滞微分不等式与解的关系等方法,建立能源价格方程解的振动准则,通过判定特征方程有无实根,得出方程解振动的2个充分条件.
The oscillation of time-delay energy price equation at equilibrium point is researched by two methods. One is proofed by contradiction which uses the measures of time-delay differential relationship between inequality and solutions,and establishes the equations guidelines of energy prices. The other one is to determine whether there exist real roots of the characteristic equation to derive equations with two sufficient conditions.
