研究了具有强迫项的ｎ项非线性时滞微分方程的解的振动性与渐近性，获得了某些充分条件，在这些条件下，如ｎ为偶数，方程的所有解振动：如ｎ为奇数，方程的每个解或者振动，或者趋于零，对文（１－２）中的定理作了较大的改进。
The asymptotic and oscillatory behavior of n th order forced delay differential equations is studied.A suffcient condition is obtained,under which all solutions of equation are oscillatory for n even,and every solution of equation either oscillator
