| Abstract: |
| The proficiency testing to determine nitrogen oxide in exhaust gas was organized in the way of field technical competition. The iterative robust z-ratio method after data conversion was adopted for data statistics. Combined with the full coverage of on-site technical verification， the accidental errors of participating institutions were found and the common problems existed in various institutions were revealed through statistical analysis. This work helps agencies identify their own problems and understand the technical problems of other institutions from the technical feedback of the organization， so as to enhance the ability of technical personnel and promote the improvement of the technical ability of the industry. |
