为研究次生断裂的形成原因、隧道结构破坏特征及其机理。以福宜高速公路梁王山隧道为依托,采用MatDEM离散元结合现场测试的方法,模拟断层运动和隧道破坏。结果表明:受主断层两侧地层相向运动影响,在离FW4断层出口远端软弱地层产生了次生断裂,隧道开挖后围岩次生裂隙扩展并发生不均匀破坏,表现为拱顶开裂,边墙强烈内挤和纵向裂缝等;低刚度裂缝能吸收变形产生明显变形阻断作用,但却容易引起对向侧部围岩的进一步应力集中,加剧隧道的不均匀破坏;为避免受次生断裂影响下穿越断层破碎带隧道发生破坏,应对次生裂缝或节理进行注浆加固,减少新生裂缝数量,削弱附近围岩的应力-变形集中,降低隧道施工风险。

地表水所含微塑料(MPs)的老化破碎过程可导致溶解性有机物(DOM)释放,进而对水环境及水处理过程造成潜在风险.为探索MPs在典型水处理氧化过程中的老化和有机物释放特性,本研究选取聚酰胺66(PA66)和聚对苯二甲酸乙二醇酯(PET)为研究对象,探究了典型工业级MPs在模拟水处理氧化(UV、UV/H_(2)O_(2)、O_(3))过程中的DOM析出规律.结果表明:①3种典型氧化过程均加速了MPs-DOM的溶出,PA66的DOM生成量[以溶解性有机碳(DOC)计]相对于PET更高.②在对照组、UV氧化、O_(3)氧化下,PA66-DOM和PET-DOM的DOC值均随反应时间及氧化剂浓度的增加呈上涨趋势,而在UV/H_(2)O_(2)氧化下呈先增加后减小的规律,且3类氧化中O_(3)技术对2类MPs的氧化效果相对更好.③MPs表层的官能团在氧化处理前后未有较大差异,其羰基指数(CI)均有一定程度的升高.④PA66与PET所产生的DOM在官能团构成及荧光组分上较为相似,主要由类色氨酸、类络氨酸、可溶性微生物代谢产物组成.研究显示,以PA66和PET为代表的工业级MPs在高级氧化水处理过程中会析出DOM,对后端消毒等工艺产生潜在影响.

The Fenghuangshan skarn-type Cu deposit, Tongling Ore Cluster, Anhui Province, is an important component in the Middle-Lower Yangtze River ore-forming belt. To better understand magmatism and its relationship to mineralization, we investigated geochemical features, ore-forming fluids, and geochronology of the Xinwuli intrusion and the related Fenghuangshan Cu deposit. Lithogeochemical characteristics show that the Xinwuli quartz monzodiorite is formed by mixing magma derived from upper mantle alkaline basalt that has been contaminated by crust materials. C, H and O isotopes indicate that ore-forming fluids mainly come from the magma, with minor amounts of meteoric fluids involved at the late stage. S and Pb isotopic components indicate that ore-forming materials are derived from the mantle. Molybdenite Re-Os isotopic dating yields Re-Os model ages ranging from 139.1±2.4 Ma to 142.0±2.2 Ma, with an isochronal age of 141.1±1.4 Ma, which is consistent with sensitive, high-resolution ion microprobe （SHRIMP） zircon U-Pb ages of quartz monzodiorite and granodiorite in the mining area. Dating analysis yields ages from 136.0±2.0 Ma to 143.0±2.4 Ma for the quartz monzodiorite （a weighted average of 139.4±1.2 Ma） and ages from 136.7±2.0 Ma to 145.3±2.4 Ma for granodiorite （a weighted average of 141.0±1.1 Ma）.

消毒是保障饮用水安全的重要环节,但不可避免会加剧耐氯性细菌的筛选和强化。与传统汞灯相比,紫外线发光二极管(UV-LED)和KrCl准分子灯作为灭活微生物的创新技术具有多项优势。以给水管网中筛选出来的假单胞菌和琼式不动杆菌2种致病性耐氯菌为研究对象,开展了不同紫外波段包括传统紫外灯LPUV(254 nm)、新兴UV-LEDs(265 nm、285 nm)和222 nm KrCl准分子灯对耐氯菌的灭活特性研究。研究结果表明:4种紫外波段对2种耐氯菌均具有较高的灭活效果,在较低的剂量内(8~10 mJ/cm^(2))2种菌灭活率达到2~5 log。2种耐氯菌从灭活率和灭活速率常数比较4种光源的灭活效果依次为:265 nm>254 nm>285 nm>222 nm,而2种菌对不同波段敏感度比较得出:265 nm>254 nm>222nm>285 nm,综合来说UV-LED 265 nm对2种耐氯菌灭活效果最佳。同时基于研究结果从耐氯菌处理效果和应用场景适配性等方面提出了对应的新兴紫外消毒技术工艺应用建议。

In this article, 12-acryloyloxystearic acid was synthesized, which was then used to prepare the magnesium 12-acryloyloxy stearate detergent. Reaction conditions for synthesizing 12-acryloyloxystearic acid, including the molar ratio of 12-hydroxystearic acid to acrylic acid, the catalyst amount, the esterification temperature, and the esterification time, were optimized. Under the optimized conditions, the 12-acryloyloxystearic acid with an acid value of 159 mg KOH/g and a melting range of between 70.4 ℃ and 71.4 ℃ was obtained. The structure of 12-acryloyloxystearic acid was confirmed by FTIR spectroscopy. Results of preparing magnesium 12-acryloyloxy stearate detergent showed the existence of acryloyloxy radical in 12-hydroxystearic acid could improve the quality of lubricant detergent greatly.
