Identifying the regional heterogeneity characterizing mechanisms influencing carbon emissions is crucial to scientific formulation of emission reduction targets and strategies. The studies that have been conducted limitations in terms classification criteria study scales, their findings are limited reflect actual situation. In this study, perspective main functional area chosen as entry point carry out classification. First, 305 county-level administrative districts Yangtze River Delta urban...
Direct power scaling of an at-source scalar orbital angular momentum (OAM) laser is demonstrated in a Ho:YAG single-crystal fiber (SCF). Benefiting from the long gain region and large surface-to-volume ratio this fiber-like geometric structure, 100 W optical vortex (OAM = ℏ ) with high slope efficiency 66.0% achieved at 2.1 µm, which is, to best our knowledge, record OAM 2 µm spectral range opens new route for direct generation high-power, high-efficiency structure light beams.
The direct reaction of CO2 with ethylene diamine (EDA) to produce urea (EU) provides significant potential for the resourceful utilization CO2. Herein, we systematically synthesized a series of...
Accurately identifying the fault type of an optical current transformer (optical CT) and evaluating severity can provide strong support for operation maintenance a direct (DC) power system. In response to problems that research overlooks, spatiotemporal features when making identification, which restrain improvement identification accuracy, consider as assessment severity, is unable effective information actual work, this paper proposes CT model based on scene generation feature fusion....
Structured light fields with high degrees of freedom, particularly those orbital angular momentum (OAM) states associated the rotation phase front, give rise to a range novel physical phenomena in light–matter interactions. However, direct generation scalar OAM at source faces limitations power scaling, and their amplification remains an open challenge due limited gain mode purity. In this work, we present straightforward approach directly amplify optical vortices by employing two-stage...
Abstract We report on a high-efficiency, high-power tandem Ho:YAG single-crystal fiber (SCF) laser in-band pumped by Tm-doped at 1907 nm. In addition to the uniform heat distribution resulting from large surface-to-volume ratio of this fiber-like thin-crystal rod, long gain region provided layout two SCFs enables high lasing efficiency and power handling capability. More than 100 W output is achieved 2.1 μm, corresponding slope 70.5% an optical-to-optical 67.6%. To best our knowledge,...
Abstract Renewable portfolio standards (RPS) are important guarantees to promote renewable energy (RE) consumption. The tradable green certificate (TGC) trading mechanism is a supporting of RPS, but the rate TGC low and there double-metering problem RE With introduction new policies in China, we innovatively take electricity-selling side as subject consumption responsibility biomass-based electricity-generation (BEG) projects considered participate trading. To explore interaction between...
This paper proposes a novel metasurface-based monopulse antenna. A multimode pyramidal horn with four ports is selected as the feed of proposed The 3-dB couplers and optimized waveguide phase shifters are employed to design comparator. In order obtain good sum difference beams performance, metasurfaces mounted on bowl structure radiate electromagnetic wave from sub-reflector. An experimental prototype has been fabricated measured at Ku-band. results show that gain ratio between 2.8 dB 3.7...
Only the specific participants of energy internet platform can be targeted to develop diversified products and services, so this paper divides rural into four typical scenarios: government, public, agriculture industry. First, through assisting government formulate appropriate energy-related policies, make reasonable power planning decisions carry out accurate industrial investment allocation; Second, by helping users reduce costs, improve efficiency experience; Finally, improving...
The energy internet platform not only integrates multiple types of forms, but also involves the benefit distribution subjects during construction and operation. How to evaluate objectively accurately is foundation for platform. To this end, comprehensive evaluation index system proposed. was weighted by method analytic hierarchy process entropy weight combining subjectivity objectivity. Then, cloud chart determined constructing fuzzy synthetic matrix based on model generate digital...
This paper divides the application scenarios of rural Energy Internet platforms into four aspects: smart care, heating, agriculture and industry commerce according to market user needs. Then platform is used as an industrial form, business model canvas theory analyze service mode platform. The analyzed from nine important partners, key business, core resources, value proposition, customer relationship, channel path, segmentation, cost structure income source. Finally, future development...
Olkin [3] obtained a neat upper bound for the determinant of correlation matrix. In this note, we present an extension and improvement his result.
