厘清农村劳动力转移与耕地利用可持续集约化之间的关系对于促进农业可持续发展具有重要意义。该研究基于1990—2020年中国省级面板数据，采用超效率SBM模型测算耕地利用可持续集约化水平，运用面板门槛模型探讨农村劳动力转移对耕地利用可持续集约化的影响效应。结果表明：1)1990—2020年中国耕地利用可持续集约化水平总体呈先下降后上升的趋势，区域间差异显著；2）农村劳动力转移对耕地利用可持续集约化存在非线性影响，当农村劳动力转移水平小于0.351时，农村劳动力转移不利于耕地利用可持续集约化的增长；超过这一门槛后，农村劳动力转移对耕地利用可持续集约化产生显著的增长效应；3）农村劳动力转移对耕地利用可持续集约化的影响存在非均衡效应，即农村劳动力转移对农业发达地区与平原地区的促进作用显著，但对农业欠发达地区与山地地区的促进作用尚不显著。基于此，应合理引导农村冗余劳动力非农转移，以推动耕地利用可持续集约化转型；同时，应注意耕地利用可持续集约化提升的自然环境禀赋与农业经济发展水平制约，因地制宜的探索适宜地区条件的耕地利用可持续集约化发展路径。

Journal of Materials Science & Technology 2017年第7期33卷 661-667页

The results of the surface modification of magnesium alloys by plasma electrolytic oxidation（PEO） and subsequent treatment in suspension of the superdispersed polytetrafluoroethylene（SPTFE） or telomeric solution of tetrafluoroethylene（TFE） are presented. Composite coatings hav. been obtained by dipping with subsequent heat treatment. Electrochemical, tribological properties and wettability of protectiv. composite coatings hav. been inv.stigated. Composite coatings formed on PEO-layer by fourfold treatment of samples in SPTFE suspension possess best protectiv. properties. The obtained coatings decrease the corrosion current density（5.4 × 10^（-11） A cm^（-2）） and wear（7.6 × 10^（-7）mm^3（Nm）^（-1））, and increase the polarisation resistance（1.7 × 10~9 cm^2） and impedance modulus（1.9 × 10~9 cm^2） by orders of magnitude in comparison with unprotected magnesium alloy and base PEO-coating. The highest v.lue of contact angle（CA） has been obtained for coatings with triple application in telomeric solution. CA for such composite coatings attains（171 ± 2）？, as the result of multimodal roughness of the composite coating＇s surface.

Water Photomolecular Ev.poration Due to Light-Mediated Ortho-Para Spin Transitions

引用

Open Journal of Applied Sciences 2024年第8期14卷 2201-2206页

作者： sergey Pershin Irina Bjørnø Michael Grishin Prokhorov.General Physics Institute of the Russian Academy of Sciences Moscow Russia RKMD Copenhagen Denmark

Recent discov.ries hav. rev.aled a groundbreaking phenomenon where light alone, without any thermal input, can induce water ev.poration, termed the “photomolecular effect”. This study explores a nov.l hypothesis that this effect can be explained by ortho-para magnetic spin interactions in water molecules within the water-air interface layer. Water molecules, consisting of hydrogen and oxygen, exhibit different nuclear spin states: ortho-(triplet) and para-(singlet). The interaction of polarized light with these spin states may induce transitions between the rotational lev.ls of ortho- and para-forms due to catalysts like triplet oxygen (O2) in its inhomogeneous magnetic field. Resonance pumping at 532 nm (~18,797 cm−1) due to the transition v.-v.-v. ~ 0-8-2 (~18,796 cm−1) results in an increase in molecular energy sufficient to ov.rcome intermolecular forces at the water surface, thereby causing ev.poration. The proposed ortho-para conv.rsion mechanism inv.lv.s spin-orbit coupling and specific resonance conditions. This theory prov.des a quantum mechanical perspectiv. on the photomolecular effect, potentially offering insights into natural processes such as cloud formation and climate modeling, as well as practical applications in solar desalination and industrial drying. Further experimental v.lidation is required to confirm the role of spin interactions in light-induced water ev.poration.

In this paper, we first present an experimental demonstration of terahertz radiation pulse generation with energy up to 5 pJ under the electron emission during ultrafast optical discharge of a v.cuum photodiode. We use a femtosecond optical excitation of metallic copper photocathode for the generation of ultrashort electron bunch and up to 45 kv.cm external electric field for the photo-emitted electron acceleration. Measurements of terahertz pulses energy as a function of emitted charge density, incidence angle of optical radiation and applied electric field hav. been prov.ded. Spectral and polarization characteristics of generated terahertz pulses hav. also been studied. The proposed semi-analytical model and simulations in COMSOL Multiphysics prov. the experimental data and allow for the optimization of experimental conditions aimed at flexible control of radiation parameters.
