It is proved that strong countable compact set is a strong fuzzy paracompact if and only if it is a strong fuzzy compact, strong fuzzy compact set and fuzzy unit interval are strong fuzzy paracompact, the product of a strong fuzzy compact set and a strong paracompact set is strong fuzzy paracompact, a strong t2strong fuzzy paracompact space is strong 5 - regular and strong s - normal, a strong 5 - regula
證明了每個強fuzzy緊集和fuzzy單位區間i廠）都是強fumy仿緊的；強fuzzy緊集和強fuzzy仿緊集的乘積是強fuzzy仿緊集；強tz的強fuzzy仿緊空間是強s 「一正則的；強tz的強fuz 。 -
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，可數仿緊（中緊、亞緊）空間及遺傳中緊空間是否具有類似junnila的刻畫呢?本文圍繞這個問題在上述結果的基礎上證明了一些結果。另外，中緊空間和遺傳中緊空間的可乘性問題一直受到人們的關注，但還沒有好的結果，本文證明了一個關于正規中緊空間及遺傳正規且遺傳中緊空間的逆極限的結果。 -
Countable product of 1 - like spaces is a d - space
