Promoting the coordinated development of "population-land-industry" in resource-based shrinking cities is the difficulty and challenge to realize regional high-quality development. This research constructed the evaluation index system of population, land and industrial development level, and used the coupling coordination model to analyze the "population-land-industry" coordinated development of 26 resource-based Shrinking Cities in China in 2008, 2013 and 2018. The results show that: (1) The development level of industrial system in resource-based cities is high, the development of land system is at the middle level, and the development of population system is low. The coordination degree of "population-land-industry" in each city is at the level of near imbalance and slight imbalance, but most cities have an upward trend; (2) There are obvious differences in the development level and coordination degree of population, land, and industry of different types of resource-based shrinking cities. From the development stage, the development level of grown-up cities is the highest, while that of recessionary cities is the lowest. In 2008 and 2013, the average coordination degree ranked as growing city > grownup city > regenerative city > recessionary city, and in 2018, it is growing city> regenerative city > grown-up city > recessionary city. From the perspective of leading industries, the development level of oil&gas-based cities is the highest, while that of coal-based cities is the lowest. In the three years, the order of the average coordination degree is oil&gas-based city > nonmetalbased city > ferrous metal-based city > forestry-based city > coal-based cities. (3) The coordinated development model of "population-land-industry" in resource-based shrinking cities is dominated by population lag and land lag. [ABSTRACT FROM AUTHOR]

研究了温度、液相搅拌速度、表面活性剂体积分数等因素对乳化液膜吸收甲苯气体的气液传质影响，实验发现甲苯在乳化液膜体系中的气液传质系数随着温度的上升而增大，随液相搅拌速度的增大而增大；表面活性剂会增大气液传质阻力，减小气液传质系数，表面活性剂体积分数2%时对甲苯气液传质产生的阻力占总传质阻力的31.9%.

使用以煤油为油相, Span-85为表面活性剂制取的乳化液吸收甲苯废气,考察了表面活性剂浓度、进口甲苯气体浓度及喷淋液气比对吸收效率的影响,实验在填料塔中进行.结果表明,表面活性剂浓度小于2%时,表面活性剂对吸收效果影响较小,而大于2%时,随着浓度的增大吸收效率有明显的减小；进口甲苯浓度在300~900 mg • m-3的范围内,吸收效率随着甲苯浓度的提高而提高；喷淋液气比在3.0~5.0 L • m-3范围内,吸收效率随着液气比的增大而提高.在选择合适的乳化液及喷淋液气比基础上,处理浓度为300~900 mg • m-3低浓度甲苯废气,吸收效率可达85%以上.
