以化学测量回收率定义及其过程特点为依据，分析了3种流行公式的适用性，认为它们都不是普适公式而各有其适用条件，随意套用获得的结果可靠性较低。思考了合理评估方法，认为化学回收率不是一个直接测量量，其不确定度是各复合因素合成的结果；平均回收率不确定度只是回收率总不确定度中的一个重复性分量，只有当它占绝对优势时才可代表回收率总不确定度；遵循过程与模型的评估原则可获得针对性强、可靠程度高的评估结果。

Based on the definition and process feature of recovery percentage , the present authors analyzed the applicability of three popular formulas , it is deemed that these formulas are not universally used while each has specific conditions of application , and the reliability of results obtained by indiscriminately using the formulas is low.The reasonable assessment method is thought aabout , it is found that the recovery percentage in chemical analysis is not a direct measuring quantity , the uncertainty of recovery percentage should be the synthetic result of some composite factors , and the uncertainty of average recovery percentage is just the repetitive components in overall uncertainty of recovery percentage , and average recovery percentage can represent the overall uncer-tainty of recovery percentage only when it is dominated .It is recommended that by complying with the process and the principles of evaluating model , a higher reliability of the result can be obtained .
