为探究苏皖鲁豫区域光化学污染特征,于2021年10月和2022年6月在淮北市开展光化学污染产物过氧乙酰硝酸酯(peroxyacetyl nitrate,PAN)的在线监测,分析了PAN浓度特征、空间来源、产生速率和变化趋势.观测结果表明,观测处2021年10月PAN的浓度范围为(0.08—1.44)×10^(−9),2022年6月的浓度范围为(0.61—5.72)×10^(−9);PAN的峰值大部分出现在NO/NO_(2)比值较低的时段.结合气团后向轨迹,2021年10月观测处PAN的潜在源贡献函数(PSCF)高值区范围出现在南部方向,可能是因为西南方向相近城市较高的前体物排放;2022年6月高值区主要出现在北部和东南部,显示山东省西南部是潜在源贡献地区,东南方向的气团在工业化程度较高的城市群之间存在长距离运输.

We study inhomogeneous projective oscillator representations of Lie superalgebras of Qtype on supersymmetric polynomial algebras. These representations are infinite-dimensional. We prove that they are completely reducible. Moreover, these modules are explicitly decomposed as direct sums of two irreducible submodules.

Enhancing the therapeutic effect of existing treatments or developing new non-invasive treatments are important measures to achieve high-efficiency treatment of malignant *** therapy(PDT)is an emerging treatment modality,and the key for achieving high-efficiency PDT is to select light with strong tissue penetration depth and enhance the generation of reactive oxygen species(ROS).Although the upconversion nanoparticles(UCNPs)modified with the photosensitizers could achieve PDT with strong penetration depth under near-infrared light irradiation,the ROS generated by traditional single-pathway PDT is still ***,we developed a novel nanoconjugate(UCNP-Ce6/AIEgen)for dual-pathway reinforced PDT,in which the UCNPs were co-modified with chlorin e6(Ce6)and luminogen with aggregation-induced emission(AIEgen).Due to the presence of AIEgen,UCNP-Ce6/AIEgen could avoid aggregation-caused luminescence quenching in biological water environments and convert upconversion luminescence(UCL)of UCNPs to Ce6-activatable ***,under the irradiation of 808 nm laser,UCNP-Ce6/AIEgen can not only undergo direct lanthanide-triplet energy transfer to activate Ce6,but also convert the UCL of UCNPs to the light that can activate Ce6 through Fӧrster resonance energy transfer to generate more ROS,thus promoting tumor cell *** work broadens the applications of nanoconjugates of lanthanide-based inorganic materials and organic dyes,and provides a conception for reinforced PDT of tumors.
