求翻译：经过滤得到的稀磷酸和经浓缩得到的浓磷酸都是杂质的过饱和溶液，并含有固体杂质。稀磷酸和浓磷酸都必须进行陈化、澄清，都是利用固体杂质在磷酸中的溶解度变化原理和重力沉降分离液、固相。是什么意思？

Supersaturated solution of concentrated phosphoric acid is phosphoric acid obtained by the filter and was concentrated impurities, and contains solid impurities. Phosphoric acid and concentrated phosphoric acid must be aging, clarify, are the use of solid impurities in the phosphoric acid solubility

The filtration of the espresso, phosphoric acid and phosphate concentration of the contaminant is over-saturation of the solution, and contains solid impurities. Dilute phosphoric acid and phosphate concentration must be clarified, Chen, and is used in solid impurities in the phosphoric acid solubil

The thin phosphoric acid and the thick phosphoric acid obtains which after the filtration which obtains after the concentration all is the impurity supersaturated solution, and includes the shot.The thin phosphoric acid and the thick phosphoric acid all must carry on Chen Hua, clarify, all is uses t

Filtering are dilute and concentrated phosphoric acid be supersaturated solution of concentrated phosphoric acid are impurities and solid impurities. Dilute concentrated phosphoric acid and phosphates are aging, clarification must be made, is the use of solid impurities in phosphoric acid solubility
