摘要：
The delay differential equation with piecewise constant argument x' (t)+a(t)x(t) +b(t)x([t-k]) = 0 is considered, where a(t) and b(t) are continuous functions on [-k ¥),b(t) ≥0,k is a positive integer and [ • ] denotes the greatest integer function. Some new oscillation and nonoscillation conditions are obtained. © 2000 Springer Verlag.
