In connection with the current prospect of decarbonization of coal energy through the use of small nuclear power plants (SNPPs) at existing TPPs as heat sources for heat supply to municipal heating networks, there is a technological need to improve heat supply schemes to increase their environmental friendliness and efficiency. The paper proves the feasibility of using the heat-feeding mode of ASHPs for urban heat supply by heating the network water with steam taken from the turbine. The ratio of electric and thermal power of a “nuclear” combined heat and power plant is given. The advantage of using a heat pump, which provides twice as much electrical power with the same heat output, is established. Taking into account that heat in these modes is supplied with different potential, the energy efficiency was used to compare these options. To increase the heat supply capacity, a scheme with the use of a high-pressure heater in the backpressure mode and with the heating of network water with hot steam was proposed. Heat supply from ASHPs is efficient and environmentally friendly even in the case of significant remoteness of heat consumers.

Imaging the western boundary of the Sichuan Craton from multiple geophysical observations

Journal of Earth Science 2024年

The boundary between the cratonic and orogenic lithospheres is one of the most significant seismogenic zones characterized by strong lithospheric deformation. As the essential tectonic block bounding the eastern Tibetan Plateau， the Sichuan Craton (SCC) resists the eastward escape of Plateau’s crustal materials， resulting in the uplift of the Songpan-Ganzi Block (SGB) and the crustal deformation of the Longmenshan tectonic belt (LMTB). To uncover the compressional structures and deformational mode of the LMTB and SCC， it is crucial to determine the precise location and geometry of the western boundary of the SCC. To address this issue， the lithospheric properties of the obduction SGB， the underthrusting SCC， and the LMTB were analyzed using a series of geophysical data， including seismic reflection profiles， magnetotellurics， aeromagnetics， gravity， and seismic tomography. The crust of the SGB is characterized by low magnetism， low seismic velocity， low resistivity and low Bouguer gravity， while that of the SCC features non-uniform high magnetism， high seismic velocity， high resistivity and high Bouguer gravity. The LMTB， as the boundary between the SGB and SCC， shows the geophysical characteristics similar to the SCC along the southern and central segments. The integration of all these geophysical observations suggests that the SCC’s western boundary follows the Yingxiu-Beichuan fault along the northern segment， without obvious underthrust. However， this boundary is located west of the Wenchuan-Maoxian fault zone along the southern and central segments， with distinct westward wedging/underthrusting. The irregular geometry of the SCC’s western boundary can further explain the variation in structural deformation along the LMTB. By comparing the differences in crustal thickness and lithospheric strength between the SGB and SCC， this study suggests that the varying crustal strength between tectonic blocks may be the controlling factor for the irregular geometry of the

在2024年年底之前,将有4人登上航天器,飞往月球、绕月之后再返回地球。是的,曾经去过,曾经做过。但那已经过去50多年了。美国国家航空航天局的“阿尔忒弥斯二号”任务是2025年登月计划的热身,这将标志着自1972年“阿波罗17号”任务以来,美国首次有宇航员离开近地轨道。“这表明,美国正在恢复已失去几十年的技术能力,正在计划让宇航员重返月球。”英国莱斯特大学副教授布莱丁·鲍文(Bleddyn Bowen)说,“经过几十年的概念艺术、含糊其词的承诺、总统和国会的犹豫不决,现在看到一次真正的载人绕月任务,确实令人振奋。”
