	<span style=\"line-height:1.5;\">利用2016年11月至2017年5月北京地区的微脉冲激光雷达资料，统计分析了卷云的云底高度、厚度以及光学厚度。结果表明卷云的云底高度主要分布在5~10 km之间，平均海拔高度是7.04 ± 1.10 km，随着云底高度的增加，卷云出现频率逐渐减小；卷云的厚度主要分布在0.3~1.5 km之间，平均值为0.73 ± 0.25 km；卷云的云底高度和厚度呈负的相关关系；卷云的光学厚度值小于0.14，光学厚度与厚度呈正的相关关系。<br />
By using cirrus measurements with a Micro Pulse Lidar at Beijing from November in 2016 to May in 2017, the statistical analysis is made for cirrus height and thickness and optical depth is calculated. The results show that cirrus base height varies between 5 and 10 km, and the mean value is 7.04 ± 1.10 km above the sea level. Cirrus thickness varies between 0.3 and 1.5 km, and the mean value is 0.73 ± 0.25 km. Cirrus optical depth is less than 0.14. Cirrus cloud-base height and thickness showed a negative correlation. Optical thickness and thickness were positively related.</span><span style=\"line-height:1.5;\"></span>
