求翻译：To study the aerodynamic characteristics, experiments were carried out on a laboratory-scale model for an arch-fired boiler. The airflow velocity was measured by using a two-dimensional PIV. The results show that: 1) as the momentum flux ratio increases, the arch air becomes stronger and reaches deeper into the furnace是什么意思？ 待解决

学习的空气动力特性，拱燃煤锅炉上的实验室规模的模型进行了实验。用一个二维PIV测量气流速度。结果表明：1）动量通量比例增加，拱空气变得更强，达到深入炉;然而，流速分布非均匀的低炉，回流区略有扩大。动量通量率的理想值是2.54。 2）低层二次风注入倾角，其混合拱空气被推迟。所以，混合后的气体可以达到较低的燃油炉和停留时间是长期的。倾角从0°〜20°，30°和40°，分别更高的穿透深度和丰满度的气流以及可以得到较大的回流区。理想的倾角为30°; 3）相比，增加动量通量率，调整二次风倾角，更有利于提高炉膛内的气流分布。
