在构建高等教育规模与区域经济耦合协调发展评价指标体系的基础上,运用发展效益指数、改进的熵值法、Person相关系数与耦合协调度模型对粤港澳大湾区广东地区2018-2022年高等教育规模与区域经济复合系统耦合协调发展水平进行测度,并分析其时空分异特征以及高等教育规模与区域经济之间的内在互动关系。研究表明:(1)粤港澳大湾区广东地区高等教育规模与区域经济复合系统综合效益发展指数及耦合协调度总体呈现上升趋势与正向演替关系。当前,复合系统耦合协调发展处于成熟阶段,演进状态为良好协调区域经济滞后型;高等教育规模子系统与区域经济子系统同步性显著,发展呈高度正相关。(2)粤港澳大湾区广东地区高等教育规模与区域经济复合系统耦合协调演化经历了“萌芽—起步—稳定—成熟”四个发展阶段,呈现出“严重失调—濒临失调—中级协调—良好协调”四种演进状态,其在协调发展状态持续时间较长,从萌芽阶段到起步阶段增速最快。(3)粤港澳大湾区广东地区各市高等教育规模与区域经济复合系统综合效益发展指数及耦合协调度的地域异质性较明显,复合系统整体呈现“多类失调交错、低质协调聚集、高质协调主导”的动态演化特征。当前,江门市耦合协调发展水平最优,演进状态为优质协调区域经济滞后型,其次为广州市与惠州市,而中山市耦合协调发展水平最低,演进状态为初级协调区域经济滞后型。针对上述结论,提出了粤港澳大湾区广东地区高等教育规模与区域经济系统深度耦合协调发展调适策略。

为减少费约果细胞壁中果胶和半纤维素等物质对果汁品质的负面影响,提高果汁出汁率,本文研究了复合酶(半纤维素酶和果胶酶)比例、加酶量、温度、时间对“Unique U-100”费约果果汁出汁率和可溶性固形物的影响。在单因素实验的基础上,进行四因素三水平的响应面优化。结果显示:在复合酶(半纤维素酶/果胶酶)比例为2.14:1,加酶量19.6 g/L,酶解温度56.8℃,酶解时间92 min的条件下,费约果果实出汁率最高,为79.5%,与模型预测值相对误差为5.67%;果汁中可溶性固形物含量为15.7%,与模型预测值相对误差为0.83%。此外,与直接压榨的费约果果汁相比,酶解后的果汁表现出更高的澄清度、总酚含量(24.4 mg GAE/100 g)和VC含量(2.42 mg/100 g)。因此,本研究优化了复合酶酶解制备费约果果汁的工艺,提高费约果果汁出汁率和营养品质,可为后续费约果果汁深加工提供理论依据。

以金属有机框架NH2-UiO-66为基础，采用“一锅法”负载缓蚀剂BTA与光热材料TiN，合成后再包覆一层与环氧树脂有较好相容性的聚多巴胺，合成了一种具有光热转换性能的纳米容器PDA@（NH2-UiO-66@BTA/TiN），以达到提高光热性能、阻止缓蚀剂不必要释放的作用。对所得的纳米容器进行形貌表征以及缓蚀剂缓释效果测试，而后将其添加在环氧涂层中进行自修复以及电化学腐蚀测试。结果表明：复合材料具有八面体结构，粒径均匀，聚多巴胺包覆在纳米容器外层后，PDA@NH2-UiO-66@BTA/TiN外壳变厚，外层的聚多巴胺和内层的光热材料TiN能够有效提高纳米容器光热性能，在光照下能够促进缓蚀剂的释放，同时在无光照情况下能够一定程度上阻止内部缓蚀剂的释放。PDA@（NH2-UiO-66@BTA/TiN）作为填料加入环氧树脂后可提高涂层的自修复性能和防腐性能，划痕处的自修复效率达到98.62%，且涂层在光照进行自修复后仍具有较好的防护能力，在3.5%Na Cl溶液中浸泡20 d后阻抗模值依然维持在10～7Ω·cm2以上，且金属基本表面基本没有腐蚀产物。将制备的PDA@（NH2-UiO-66@BTA/TiN）纳米容器添加至环氧涂层中，可显著提升涂层的自修复性和防腐性。

Black carbon(BC)plays an important role in air quality and climate change,which is closely associated with its mixing state and chemical *** this work the mixing state of BC-containing single particles was investigated to explore the evolution process of ambient BC particles using a single particle aerosol mass spectrometer(SPAMS)in March 2018 in Zhengzhou,*** BC-containing particles accounted for 61.4%of total detected ambient single particles and were classified into five types including BC-nitrate(BC-N,52.3%)as the most abundant species,followed by BC-nitrate-sulfate(BC-NS,22.4%),BCOC(16.8%),BC-fresh(BC-F,4.5%)and BC-sulfate particles(BC-S,4.0%).With enhancement of the ambient nitrate concentration,the relative peak area(RPA)of nitrate in BC-N and BC–NS particles both increased,yet only the number fraction(N_(f))of BC–N particles increased while the N_(f) of BC-NS particles decreased,suggesting that the enhanced mixing state of BC with nitrate was mainly due to the increase in the ambient nitrate mass *** addition,the Nfof BC-N decreased from 65.3%to 28.4%as the absorbing Angstrom exponents(AAE)of e BC increased from 0.75 to 1.45,which indicated the reduction of light absorption ability of aged BC particles with the enhanced formation of BC-N *** results of this work indicated a change in the mixing state of BC particles due to the dominance of nitrate in PM_(2.5),which also influenced the optical properties of aged BC particles.
