  Using the Poincar\'{e} section technique, we study in detail the dynamical
behaviors of delay differential system and find a new type of solutions $S_i$
in short-time delay feedback. Our numerical results remind us to deny the
opinion that there are no complex phenomena in short-time delay case. Many
similarities between foundamental solution and the new type of solutions are
found. We demonstrate that the scales of $S_i$ increase with exponential growth
via $i$ in the direction of $\mu $, while decrease with exponential decays in
the direction of $x$ or delay time $t_R$.
