The representative chemical index and the typical water sample were obtained by means of absolute value correlative analysis and Q type factor analysis respectively.
用绝对值关联分析和Q型因子分析等方法得出了地下水中具有代表性的化学指标和具有代表性的水样。
All the samples obtained were examined with X-ray diffraction, isothermal adsorption of water, DTA, TG, IR, TEM, and chemical analysis, and were identified as L-type molecular sieve.
产物经X射线衍射，水的等温吸附、差热分析、红外图谱，透射电镜以及化学分析等测定证实为L型沸石。
Therefore, this article on the status of water bodies, pollution type, to introduce the physical, chemical, biological repair technology.
