This paper is carrying out based on the chemical materials of huanhe group of cretaceous system of erdos basin, carrying on relativity analysis about tds and three major anion percentage of meq ( milligram equivalent ), taking cluster analyses on tds and the three anion percentage of meq, the trend analysis of the percentage of the number of fresh water and the total water with the increases of anion percentage of meq, classifies the new index, divide the groundwater into three kinds according to percentage of meq of three major anion finally defining new groundwater water chemistry : definitely bicarbonate type, relativity bicarbonate type and non - bicarbonate types, point out that the possibilities of fresh water reduce in proper order of these kinds
鄂爾多斯地下水勘查是國家重大的地質調查項目，在地下水水化學研究的幾次大型討論會議上，專家們一致認識到，能不能利用鄂爾多斯盆地地下水勘查項目中的大量地下水水質分析資料，探索出一種新的水化學類型劃分方法，對舒卡列夫分類中的25毫克當量百分數的分類界限加以重新考慮，而找出一個與淡水密切相關的x作為分類界限。本文就是以鄂爾多斯自流水盆地白堊系保安群環河組地下水水化學資料為基礎而開展相關研究的。 -
Clusters are the aggregates of a few to thousands atoms or molecules or ions their properties are neither like those for individual atoms nor the corresponding bulk and therefore clusters are named " the fifth state of the matter ". during the development of cluster science, many concepts and methods have been introduced from nuclear physics, condense matter physics and quantum chemistry, cluster science has became an new interdisciplinary field between atomic - molecular physics and condensed matter physics
團簇（ clusters ）是由2 104個原子、分子或離子通過物理或化學結合力組成的相對穩定的微觀和亞微觀聚集體，它的空間尺度在幾a至幾百a范圍內，被人們看作是介於原子分子和宏觀固體之間物質結構的新層次，並稱之為物質的「第五態」 。
