《柴油发动机氮氧化物还原剂+尿素水溶液（AUS32）快速筛查技术规范》征求意见稿编制说明

1《车用尿素快速检测方法近红外光谱法》2随着我国国六标准的全面实行，SCR（选择性催化还原）尾气后保质期大于12个月，≤35℃保质期大约6个月，在夏天，由于保质34气中继续污染环境。此外，尿素含量会影响尿素水溶尿素水溶液的尿素含量及质量。若密度和/或用于在实验室环境下进行测量，并且检验周期567按照仪器操作手册设定仪器参数，扫描波数范围：10000cm-1~8表1车用尿素各项质量指标重复性和再现性项目标准重复性再现性尿素含量AUS321密度SH/T0604折光率GB/T6140.08醛类AUS320.25碱度AUS320.03缩二脲AUS320.04不溶物AUS329表2车用尿素定标模型验证结果序号尿素折光率缩二脲碱度醛类不溶物密度近红外化验值偏差近红外化验值偏差近红外化验值偏差近红外化验值偏差近红外化验值偏差近红外化验值偏差近红外化验值偏差133.033.1-0.11.38311.3839-0.00080.140.120.010.130.130.00-0.30.11091.01090.40.6232.732.10.61.38261.3844-0.00180.280.270.010.160.20-0.042.92.80.10.20.10.21088.51088.7-0.3332.332.00.31.38211.3831-0.00100.110.100.010.150.120.032.42.20.10.60.40.21088.51087.80.7432.732.60.11.38171.3823-0.00070.210.23-0.010.150.140.022.52.20.3-0.21090.71090.10.5532.332.4-0.11.38121.3819-0.00060.260.230.020.100.090.010.12.32.5-0.11090.81090.70.1632.031.40.61.38151.38100.00050.270.260.000.130.120.00-0.10.11089.81089.30.6732.432.6-0.21.38221.3833-0.00110.260.28-0.020.160.20-0.043.03.1-0.12.72.60.11090.21090.20.0832.832.50.31.38151.38100.00050.180.20-0.030.110.100.010.0-0.11091.41091.00.3932.131.60.51.38401.38390.00010.190.21-0.020.180.20-0.022.10.32.12.2-0.11088.91089.5-0.732.332.5-0.21.38211.38130.00080.180.160.020.150.130.022.82.9-0.12.20.41088.81088.60.132.533.0-0.51.38311.3842-0.00110.140.15-0.010.160.19-0.03-0.20.80.70.11088.21087.50.732.432.9-0.41.38211.3830-0.00090.160.150.010.110.16-0.050.22.42.7-0.31091.81091.80.033.032.50.51.38171.3828-0.00110.180.20-0.030.110.070.04-0.22.0-0.21088.41088.10.332.833.3-0.51.38221.3825-0.00030.210.22-0.020.170.140.03-0.22.22.20.01088.81088.20.632.832.50.31.38291.38270.00020.260.29-0.030.180.20-0.020.30.11089.61089.40.232.131.70.41.38181.3824-0.00060.160.18-0.020.150.150.00-0.1-0.21091.91091.10.832.332.7-0.41.38391.3850-0.00110.210.180.020.120.100.01-0.10.21090.81091.5-0.632.532.20.31.38141.3817-0.00030.140.110.030.180.150.033.03.1-0.12.22.4-0.21091.01090.20.832.632.20.41.38391.3845-0.00060.210.190.020.110.15-0.032.22.00.2-0.11091.21090.20.931.931.70.21.38201.3837-0.00180.19
