“Belt and Road” is the important origin of oil import in China. Based on social network analysis and stochastic frontier gravity model, this paper studied the characteristic evolution and influence factor of oil import network between China and “Belt and Road” countries. Then by constructing a stochastic frontier gravity model including the crude oil future price and oil importing price, it found that the international crude oil future price, the oil importing price, the political situation, the trade agreements have the effects on the China's oil import from “Belt and Road” region. It provided suggestions for improving the spatial pattern of China's petroleum trade.

Cylindrical coconut activated carbon（CCAC） support was graphitized at a high temperature（1900 ℃） in argon, then oxidized with an O2-N2-H2O mixture, and treated with nitric acid. Pretreatment of carbon support on its mechanical strength, physical structure, chemical composition and surface properties of cylindrical CCAC support was investigated by X-ray diffraction（XRD）, surface area analysis, scanning electron microscopy（SEM）, energy dis- persive spectroscopy（EDS）, thermogravimetric-differential thermogravimetric（TG-DTG） analysis and temperature programmed desorption-mass spectrometry（TPD-MS）, and the effect of CCAC support on the catalytic activities was also studied. The results show that the degree of graphitization, the purity（phosphorus, sulphur）, pore struc- ture（micropore, mesopore） and oxygen-containing functional groups（--COOH, --OH, --COOR） of carbon supports are obviously different, which have a great influence on the performance of Ru-based catalysts. After a series of pre- treatments, the surface physical and chemical properties of the commercial CCAC are modified and improved, and the activity of as-prepared Ru/AC catalyst is increased significantly.

With the development of quantum computing technology, quantum public-key cryptography is gradually becoming an alternative to the existing classical public-key cryptography. This paper designs a quantum trapdoor one-way function via EPR pairs and quantum measurements. Based on this, a new quantum public-key cryptosystem is presented, which offers forward security,and can resist the chosen-plaintext attack and chosen-ciphertext attack. Compared with the existing quantum public-key cryptos,eavesdropping can be automatically detected in this new quantum public-key cryptosystem under a necessary condition, which is also detailed in the paper.

Lead-halide perovskite nanoparticles（LHP NPs） are highly promising materials for next-generation displays and solid-state lighting due to their exceptional optical properties. However, their inherent instability presents a significant challenge. Recent advances have demonstrated that optoelectronic devices based on monolayer nanoparticle films exhibit both high luminescence efficiency and long-term *** research demonstrates that mobility limitations and anisotropic alignments in CsPbBr3nanocube monolayer films are key to their stabilization, hindering spontaneous growth through face-to-face fusion and resulting in the formation of connecting necks in a diagonal direction. Introducing laser irradiation confirmed this by significantly accelerating nanocubes growth, increasing mobility, and enhancing local structural ordering, leading to larger and more regularly shaped nanosheets. Fourier transform infrared spectroscopy and energy dispersive spectroscopy line-scan analyses indicated that laser irradiation did not disrupt the ligand structure. Transmission electron microscopy and correlative cathodoluminescence electron microscopy revealed the effects of post-growth and heterogeneous structures, including enhanced luminescence and inhomogeneous intensity in the nanosheets. These findings deepen the understanding of the post-growth mechanism of monolayer nanoparticles and the structure-emission correlation and highlight the unique role of laser irradiation in directing the formation of well-defined and regular nanostructures.

研究了α+γ双相区热处理对430铁素体不锈钢热轧板显微组织和力学性能的影响,并与工业罩式炉退火后的热轧板显微组织和力学性能进行了对比分析。结果表明:在双相温度区间对430不锈钢热轧板进行热处理,分割了热轧板轧向的条带状组织,抑制了聚集组织的形成。与常规罩式炉退火工艺相比,双相区热处理显著提高了430不锈钢热轧板的伸长率,降低了屈服强度和硬度,有利于改善最终冷轧产品的冲压性能和抗起皱性。
