The abused ciprofloxacin antibiotics have caused significant environmental *** oxidative degradation of ciprofloxacin exhibits promising efficacy,it often entails excessive energy ***,it is necessary to explore an effective and ecologically sustainable degradation ***,we demonstrated that g-C_(3)N_(4) decorated with the coordinated CeO_(2)and Co_(3)O_(4)(CeO_(2)-Co_(3)O_(4)/CN)exhibited effective ciprofloxacin photodegradation via in situ H_(2)O_(2) production and activation *** indicate that the introduced CeO_(2) enhances the transference of photogenerated electrons to O_(2) by adjusting the oxygen vacancy of photocatalyst,thereby increasing the generation of superoxide radicals,which in turn generate H_(2)O_(2),resulting in a 22.4-fold increase in H_(2)O_(2) generation over g-C_(3)N_(4).Moreover,the in situ H_(2)O_(2)generation facilitated by CeO_(2) is confirmed to be essential for ciprofloxacin degradation via CeO_(2)-Co_(3)O_(4)/CN,as it provides enough oxidant for Co_(3)O_(4) to activate into hydroxyl radicals for the pollutants ***,CeO_(2)-Co_(3)O_(4)/CN achieves a ciprofloxacin degradation ratio of 97.7%within 80 *** study introduces a novel approach that combines H_(2)O_(2) generation and activation,offering an innovative perspective for achieving clean and efficient purification of antibiotic-contaminated water.

断溶体油气藏储层类型多样,非均质性极强,常规多重孔隙介质模型以及简单溶洞等势体模型难以广泛应用。文中针对断溶体油藏复杂的地质特征,考虑大溶洞向井筒的垂向窜流以及小尺度缝洞储集体分别向井筒和大溶洞的径向供给作用,建立了双层双重孔隙介质井洞垂向窜流试井解释模型;利用Laplace变换方法获得井底压力解,绘制井底压力典型曲线并划分流动段,对窜流通道传导率、大溶洞半径、裂缝传导系数比等参数进行了敏感性分析。结果表明:窜流通道传导率主要影响早期窜流“下凹”特征,数值过大或过小均会导致早期窜流“下凹”特征减弱甚至消失;大溶洞半径与大溶洞储容比也主要影响早期窜流“下凹”特征,数值越大,“下凹”特征越明显;裂缝系统传导系数比和裂缝储容比主要影响中、晚期的窜流“下凹”特征。该研究结果对复杂断溶体油藏储集体参数评价具有重要意义。

为明确新疆玉米田双斑萤叶甲成虫种群的时空动态及种群监测抽样技术,于2022—2023年比较了玉米田双斑萤叶甲成虫种群的调查方法,调查了成虫种群的时空动态,并建立了理论抽样数与序贯抽样模型。结果表明:目测法得到的成虫种群密度显著高于盆拍法与扫网法,与黄板诱集法无显著差异;调查消耗时间上目测法显著低于黄板诱集法,但显著高于扫网法与盆拍法。因此,目测法是玉米田双斑萤叶甲成虫种群调查的优选方法。在伊犁地区,玉米田双斑萤叶甲成虫种群数量动态变化呈单峰形曲线,成虫始发于6月上旬,7月中下旬为发生高峰期。在种群发生高峰期,双斑萤叶甲成虫在玉米田中为具密度依赖型的聚集分布。根据Iwao回归模型,建立了不同密度下双斑萤叶甲成虫的田间最适理论抽样公式和基于防治指标的序贯抽样技术。上述结果为新疆玉米田双斑萤叶甲成虫田间抽样调查、种群预测预报以及科学防治提供了理论依据。

Flexible printed circuit(FPC) design in complex scenarios has a list of pin concentration areas, which lead to extremely congested intersection regions while connecting the pins. Currently, it is challenging to explore the routability and to find topologically non-crossing and routable paths manually for the nets timely. The existing bus planning methods cannot offer optimal solutions concerning the special resource distribution of the FPC design. To investigate an effective way to shorten the routing time of FPC and achieve enhanced performance, a bus planning algorithm is proposed to tackle complex area connection problems. On the basis of the pin location information, the routing space is partitioned and generally represented as an undirected graph, and the topological non-crossing relationship between different regions is obtained using the dynamic pin sequence. Considering the routability and electrical constraints, a heuristic algorithm is proposed to search the optimal location of the crossing point on the region boundary. Experimental results on industrial cases show that the proposed algorithm realize better performance in terms of count and routability in comparison with numerous selected state-of-the-art router and methods.
