英文摘要：
The paper is devoted to the determination of triple-zero singularity and the generalized eigenspace associated with zero eigenvalues in R^n. A concrete reduced form for parameterized delay differential systems is obtained by using center manifold reduction and normal form calculation. The results given in [A note on the triple zero linear degeneracy： Normal forms, dynamical and bifurcation behaviour of an unfolding. Int J Bifur and Chaos, 2002, 12：2799-28201 are employed to analyze the bifurcation behavior of the parameterized delay differential system with triple-zero singularity in detail and an example is presented to illustrate the results.
