The results of the palynologic and paleobotanic analyses have allowed determining the Paleocene (including Danian) and Eocene deposits in the series of coal-bearing sediments of southeastern flanks of the Raichikhinsk brown coal field. Their age was corroborated by the palynologic and paleobotanic data. The detailed biostartigraphic data were obtained in the area"Pioneer"for the first time. The coal-bearing strata were correlated with those from the sections of the Arkhara-Boguchan brown coal field and the stratotype of the Tsagajan Formation of the Bureya Belogor’ye.

作者： v. M. Podobina Tomsk State University Tomsk Russia

Data on Late Cenomanian and Early Turonian foraminiferal assemblages in the northern palaeo biogeographical district of the West Siberian province are summarized in the paper. In addition, the section of borehole 1016 of the Parusovaya area located in the far north of the province is considered. New information on the foraminiferal zones of this stratigraphic level along with the previously known sections of the Tazovskaya, Purpeiskaya, van-Eganskaya areas provided an opportunity to carry out a correlation of these zones between the West Siberian and the Canadian provinces (Western Canada, Northern Alaska). The West Siberian Late Cenomanian Trochammina wetteri tumida, verneuilinoides kansasensis and the Early Turonian Gaudryinopsis angustus foraminiferal zones have their analogues as similar zones in the Canadian province. Due to the provided correlation of the micropalaeontological (foraminiferal) zones, their age in the West Siberian province has been clarified. Besides, similarity of the conditions of dwelling within the boundaries of the entire Arctic palaeobiogeographical realm has been observed.

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。

New method of thermal energy—to electrical energy conversion in vacuum devices with the metal (W)—dielectric nanofilm (ZrO2) electron source is offered and studied. According to estimates and results of modeling, the energy effectiveness (χ) of the proposed method may exceed χ for the known thermionic energy conversion method to 2 - 3 orders of magnitude.

The present paper is devoted to an overview on fossil Coleoptera studied from Inner Mongolia, Daohugou （Middle Jurassic, Jiulongshan Formation） and Liaoning （Upper Jurassic-Lower Cretaceous, Yixian Formation） deposited in Chinese collections. As a result, species of the tribe Sperchopsini and Hydrophilini from Hydrophilidae, families and subfamilies Silphidae, Syndesinae from Lucanidae, Pleocomidae, Trogidae, Trogissitidae, Pyrochroidae, Diaperinae from Tenebrionidae, and Cerambycidae were first registered in the Mesozoic and some families were defined as new. It was shown that many superfamilies represented in the Recent Fauna were formed within the Middle Jurassic and Lower Cretaceous. The materials examined confirm the hypothesis that Cucujiformian beetles are a younger group than other infraordera of Polyphaga （Staphyliniformia and Elateriformia） and, therefore, they appeared in the fossil record only in the late Mesozoic. It was shown and confirmed that most superfamilies appeared in the fossil records before Cucujoidea. The synonymy of Notocupes Ponomarenko, 1964; Sinocupes Lin, 1976, syn. nov.; Amblomma Tan, Ren et Liu 2005, syn. nov.; Euryomma Tan, Ren et Shih, 2006, syn. nov., non Stein, 1899 and Ovatocupes Tan et Ren, 2006, syn. nov.; synonymy of Tetraphalerus Waterhouse, 1901 and Odontomma Tan, Ren et Ge 2006, syn. nov.; and synonymy of Priacmopsis Ponomarenko, 1966 and Latocupes Tan et Ren, 2006, syn. nov. are proposed. Sinorhombocoleus papposus Tan et Ren, 2009 is transferred from the family Rhombocoleidae to Schizophoridae. Cervicatinius complanus Tan, Ren et Shih, 2007 and Forticatinius elegans Tan, Ren et Shih, 2007 are transferred from the family Catiniidae （suborder Archostemata） to superfamily Cleroidea （suborder Polyphaga： first among the family Peltidae and second as a closely related group to the latter family）. The family Parandrexidae is transferred from the superfamily Cucujoidea to Cleroidea. The ecological circumstances of the past ecosyst
