Photoanodic properties greatly determine the overall performance of quantum-dot-sensitized solar cells（QDSCs）. In the present report, the microdynamic behaviors of carriers in the nanocomposite thin-film, a Zn Se QD-sensitized mesoporous La-doped nano-TiO2 thin-film, as a potential candidate for photoanode, are probed via nanosecond transient photovoltaic（TPV） spectroscopy. The results confirm that the L-Cys ligand has a dual function serving as a stabilizer and molecular linker. Large quantities of interface states are located at the energy level with a photoelectric threshold of1.58 eV and a quantum well（QW） depth of 0.67 eV. This QW depth is approximately 0.14 eV deeper than the depth of QW buried in the Zn Se QDs, and a deeper QW results in a higher quantum confinement energy. A strong quantum confinement effect of the interface state may be responsible for the excellent TPV characteristics of the photoanode. For example, the peak intensity of the TPV response of the QD-sensitized thin-film lasts a long time, from 9.40 × 10^（-7） s to 2.96 × 10^（-4） s,and the end time of the PTV response of the QD-sensitized thin-film is extended by approximately an order of magnitude compared with those of the TiO2 substrate and the QDs. The TPV characteristics of the QD-sensitized thin-film change from p-type to n-type for the QDs before and after sensitizing. These properties strongly depend on the extended diffusion length of the photogenerated carries and the reduced recombination rate of photogenerated electron-hole pairs, resulting in prolonged carrier lifetime and an increased level of electron injection into the TiO2 thin-film substrate.

An improved weighted scale-free network, which has two evolution mechanisms： topological growth and strength dynamics, has been introduced. The topology structure of the model will be explored in details in this work. The evolution driven mechanism of Olami-Feder Christensen （OFC） model is added to our model to study the self-organlzed criticality and the dynamical behavior. We *** attack mechanism and the study of the model with attack is also investigated in this paper. We tlnd there are differences between the model with attack and without attack.

前提是事物演化及人行动的先决条件与基础。决定是一事物限定另一事物,使后者统一于前者的过程。《德意志意识形态》关于“全部人类历史的第一个前提无疑是有生命的个人的存在”的命题,把“有生命的个人的存在”判定为在全部人类历史中居于统摄性、总揽性、贯穿性地位的决定力量,把生成该历史前提判定为全部人类历史的内涵,把该历史前提得以可能的内在要求及其满足活动的范围判定为全部人类历史的外延,从而基于此建构起了作为马克思历史决定论本然形态的历史前提决定论,有效地消解了马克思历史决定论被误解和攻击的诱因。中国特色社会主义现代化事业进入新时代,以“人民至上”统摄其全部内容和过程,把“人民的存在发展”确立为新历史时代得以可能的前提,建构起了“人民的存在发展”取向的历史前提决定论,形成了马克思历史前提决定论的中国式现代化创新形态。

低空经济作为低空飞行活动与产业融合的新型综合性经济形态,具有空间立体性、区域依赖性、数字生态性、产业融合性以及辐射带动性等特征。党和政府高度重视发展低空经济,将其确定为国家战略性新兴产业,各地加紧布局,发展势头良好。但具体实践中仍存在发展低空经济的体制机制不畅、技术创新支持不足、新型基础设施不全、产业领域需不断拓展等问题。针对上述问题,文本依据螺旋理论,提出“政产学研金服用”的低空经济开放式创新生态模式。
