家用燃气灶具CO排放测试结果表征方法

Characterization of CO Emission Test Results for Domestic Gas Cooking Appliances

为了更准确地描述家用燃气灶具(以下简称灶具)CO排放结果,对3台灶具样本的CO排放测试数据做进一步的数据统计分析。统计分析3台灶具样本的CO排放值,大部分CO排放值波动在10×10^(-6)~100×10^(-6)范围,有部分CO排放值超过了200×10^(-6),离散系数普遍大于0.05,存在显著的随机性波动。通过数据集标准化处理,剔除标准化值大于1对应的CO排放值数据,形成新的数据集,分析新数据集的箱线图、标准差和离散系数。对CO排放值数据进行两轮标准化处理后,可以得到分布集中、离散系数小于等于0.05的用于更真实地表现灶具的CO排放水平的CO排放值新数据集。用该数据集的平均值、标准差、箱线图来表征相对真实的CO排放水平。

In order to more accurately describe the CO emission results of domestic gas cooking appliances （hereinafter referred to as appliance）, the CO emission test data of three appliance samples are further statistically analyzed. Most of CO emission values fluctuate in the range of 10 × 10-6 to 100 × 10-6, and part of the CO emission values exceed 200 × 10-6. The dispersion coefficients of CO emission values are generally greater than 0.05. There is a significant random fluctuation for CO emission test data. Through standardized processing of the data set, the CO emission value data corresponding to the standardized value greater than 1 are eliminated, a new data set is formed. The box-line map, standard deviation and dispersion coefficient of the new data set are analyzed. Finally, after two rounds of standardized processing of CO emission data, a new data set of CO emission values with concentrated distribution and dispersion coefficients of less than or equal to 0.05, that are used to more realistically represent the CO emission values of appliances can be obtained. The mean, standard deviation and box-line map of this data set are used to characterize the relative true CO emission levels.
