| 摘 要： | 对在用的国产乘用车怠速HC排放实测数据进行统计分析，揭示最优拟合分布并给出最优分布参数的估计值。同时还建立怠速HC排放分布密度函数和分布函数统计模型。除在具体分析方法上有所考虑外，还持别注意了样本容量的扩大问题，以保证研究结果的准确性和可靠性。根据研究结果，对现行国家标准中有关在用乘用车怠速HC排放的限值提出了明确的修改建议。

| Abstract: | According to measured HC emission data of passenger cars on idle condition, the statistical analysis on idle HC emission was made, the optimum fitting distribution was obtained and the optimum distribution parameters were estimated in the paper. At the same time, the models for distribution density function and distribution function on idle HC emission were established. Besides the above, a special attention was paid to the sample volume enlargement problem to insure the accuracy and reliability of the research results. According to the results of this research, some amendments to the relevant limit values in the Chinese National Standard about idle HC emission of passenger cars have been submitted. |
