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。

The metadynamic recrystallization （MDRX） behavior of as-cast 904L superaustenitic stainless steel was in- vestigated by double pass isothermal compression tests at temperatures of 950-1 150 ℃, strain rates of 0.05-5 s 1 and interval of 1-100 s. The effects of working parameters （deformation temperature, strain rate, pre-strain and in- terval time） on the flow curves and microstructural evolution were discussed. The MDRX fraction increased obvious- ly with the increase of deformation temperature, strain rate and interval time. The MDRX softening was controlled by the migration of grain boundary, annihilation of dislocation and dynamic recrystallization. Moreover, the kinetic model was established for the prediction of MDRX behavior of as-cast 904L superaustenitic stainless steel based on the experimental data. A good agreement between the predicted and the experimental values was achieved （correla- tion coefficient R2= 0.98）, indicating a satisfactory accuracy.

Citrus canker, caused by Xanthomonas axonopo-dis pv. citri ('Xac'), is an important quarantine disease in citrus crops. Arbuscular mycorrhizal fungi (AMF) form symbiotic interactions with host plants and further affect their disease resistance, possibly by modulating the activity of salicylic acid (SA), a key phytohormone in disease resistance. Common mycorrhizal networks (CMNs) can interconnect plants, but it is not yet clear whether CMNs promote resistance to citrus canker and, if so, whether SA signaling is involved in this process. To test this possibility, we used a two-chambered rootbox to establish CMNs between trifoliate orange (Poncirus trifoliata) seedlings in chambers inoculated (treated) or not (neighboring) with the AMF, Paraglomus occultum. A subset of the AMF-inoculated seedlings were also inoculated with Xac (+AMF+Xac). At 2 d post-inoculation (dpi), compared with the +AMF-Xac treatment, neighboring seedlings in +AMF+Xac treatment had lower expression levels of the SA biosynthetic genes, PtPAL, PtEPS1, and PtPBS3, but higher SA levels, which attributed to the upregulation of PtPAL and PtPBS3 in treated seedlings and the transfer of SA, via CMNs, to the neighboring seedlings. At 4 dpi, the pathogenesis-related (PR) protein genes, PtPR1, PtPR4, and PtPR5, and the transcriptional regulatory factor gene, PtNPR1, were activated in neighboring seedlings of+AMF+Xac treatment. At 9 dpi, root phenylalanine ammo-nia-lyase activity and total soluble phenol and lignin concentrations increased in neighboring seedlings of+AMF+Xac treatment, likely due to the linkage and signal transfer, via CMNs. These findings support the hypothesis that CMNs transfer the SA signal from infected to neighboring healthy seedlings, to activate defense responses and affording protection to neighboring plants against citrus canker infection.
