五夸克是研究KN物理的唯一理由吗？
Is the Pentaquark the Only Justification for Research on KN Physics ?
摘要：
这个演讲的目的是激励使用DA $Φ$ NE-2在$ϕ$峰运行作为一个强烈的，清洁的低动量带电和中性K介子的来源。它涵盖了几个开放的问题仍然没有解决后超过25年和物理（其中一些仍然是小说），只能以这种方式学习。当然，上述问题的答案是{ \sl NO}。
英文摘要：
The talk is intended to motivate the use of DA$Φ$NE--2 running at the $ϕ$ peak as an intense, clean source of low--momentum charged and neutral kaons. It covers a few open problems still unsolved after more than twenty--five years and the physics (some of it still novel) that could be learned only in this way. And, of course, the answer to the above question is {\sl NO}.
