By the theory of difference equation and the construction of proper vector Liapunov function, we for the first time get the sufficient conditions for the permanence, extinction and balancing survival for this ndimensional system, which are all independent on the delays, hence under peroper conditions the time delays of this system are both harmless and profitless.

通过运用差分方程理论以及构造适当向量Liapunov泛函的方法，首次得到了此类系统多维自治的情形下系统持续生存、灭绝和残存的充分条件，这些充分条件均不依赖于时滞，因而在一定条件下，此系统中的滞后因素既是无害时滞也是无益时滞。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
