摘要良紧性是格上拓扑学最重要的概念之一，具有可乘性质，而对于相对乘积运算，它的可乘性又如何？本文证明了良紧性同样具有相对可乘性质。
Are there similar characterizations for the countable paracompact ( mesocompact , metacompact ) space and hereditarily mesocompact space ? in this paper , on the basis of the aboves , we obtain some results about them . and the product properties of mesocompact spaces and hereditarily mesocompact spaces have been paid attention . but there is no good result about them . in this paper we obtain a result about the limit of the inverse system of a normal mesocompact space and a hereditarily normal and hereditarily mesocompact space
那末，可数仿紧(中紧、亚紧)空间及遗传中紧空间是否具有类似junnila的刻画呢?本文围绕这个问题在上述结果的基础上证明了一些结果。另外，中紧空间和遗传中紧空间的可乘性问题一直受到人们的关注，但还没有好的结果，本文证明了一个关于正规中紧空间及遗传正规且遗传中紧空间的逆极限的结果。
