本計畫依據工作契約書之規範，已完成預定之各項工作，對於本計畫，工作小組提出之結論如下： 一、本年度之總查核檢校站數為1952站次。調查結果全國定檢站共1893家，查核結果4站申請停站，59站不合格，總體不合格率為3.1％。查核不合格之定檢站均已完成複檢，複檢結果全部合格。 二、本計畫實施增加複檢頻率之再查核工作，查核對象為初檢不合格之定檢站、環檢所外部查核不合格之定檢站與查核偏差較大之定檢站共400站次，再查核結果有2站仍不合格，工作人員已現場開立改善建議書並已完成複檢，複檢結果均合格。 三、本計畫實施標準氣體比對作業1889站，主要分布在0-2％之間，約佔所有校正氣體的90％。 四、由初檢查核不合格原因分析可知屬於儀器本身問題（包含採樣系統問題與線性偏差）之數量為48台，佔全體不合格數量比率之81.4％，屬於人為校正不確實之問題有11台，佔全體不合格數量比率之18.6％，這資料顯示定檢站人員有加強再教育之必要。 五、由本年度查核資料與歷年查核資料之機齡分析結果，可知雖然分析儀機齡較高者其查核不合格率亦有較高趨勢，但機齡較低者若未經適當保養亦會有較高之不合格率。 六、由91年度到93年度之查核結果來看，自全面普查以來不合格率有下降趨勢，顯見定檢站對於分析儀之檢測品質之維繫觀念已落實。

This project according to the standard of the contract, and various works that have already completed to schedule. For the conclusion is as follows: One, this year the audit and calibrate 1952 vehicle emission analyzers, the total work is 1893 times. The result shows the 4 stations that applicant for nonworking, and 59 stations are unqualified, unqualified rate is 3.1%. The audit unqualified station all have already completed the recheck, and the recheck result is all qualified. Two, this project increases the recheck frequencies, and it is total 400 stations that contain the beginning-audited unqualified stations, and NIEA audited unqualified stations and the deviation stations. The result has 2 stations still unqualified, the staff members had already drawn improvement suggestion and had already completed the recheck, which the result was all qualified. Three, this project carries out the standard air compare to 1889 stations, the error mainly distributes between 0-2%, about have all 90%. Four, the analysis by the beginning-audited unqualified stations that is belong to the instrument problem that include sampling system and the line deviation is 48 sets, account for 81.4% of unqualified quantity ratio of all, and belongs to the problem that the factitiousness corrects the incertitude to have 11 sets, account for 18.6% of unqualified quantity ratio of all. This data manifestation settles have to reeducation. Five, examine the data from this year with examine the analyzers age analysis result of the data through the years, although the analyzers age is as higher as the unqualified rate to also have the higher trend. However, if the analyzers age is lower and less maintain, there would be the higher and unqualified rate. Six, from 2002-2004 years, the audited result shows that from overall census the unqualified rate descends the trend, the clearly shows vehicle emission analyzer station for analysis instrument of examination quality have already carried out.
