教育、科技、人才三者关系的历史嬗变,先后经历了非同步出现的弱关联阶段、同步存在的明显交互阶段、多元联动的整合发展阶段,并在中国式现代化进程中进入深度融合的一体推进阶段。在中国式现代化对三者关系的重构调整中,教育、科技、人才三者形成了一体联动的协同运行关系,其中,教育是协同运行的基础,人才是协同运行的纽带,科技是协同运行的动力;三位一体的“三角协调”运行、良性互动的“循环互促”逻辑、衔接互补的“融合联动”发展,是三者一体协同推进的根本逻辑。三者关系的正确处理需从不同维度分别以三者各自为核心集中采取措施:聚焦教育的基础性作用,坚持教育优先发展;聚焦人才的主体性支撑,实施人才引领驱动;聚焦科技的动力性作用,强化科技自立自强。

Extreme ultraviolet(EUV) spectra emitted from low-Z impurity ions in the wavelength range of10–500Å were observed in Experimental Advanced Superconducting Tokamak(EAST)discharges. Several spectral lines from K-and L-shell partially ionized ions were successfully observed with sufficient spectral intensities and resolutions for helium, lithium, boron, carbon,oxygen, neon, silicon and argon using two fast-time-response EUV spectrometers of which the spectral intensities are absolutely calibrated based on the intensity comparison method between visible and EUV bremsstrahlung continua. The wavelength is carefully calibrated using wellknown spectra. The lithium, boron and silicon are individually introduced for the wall coating of the EAST vacuum vessel to suppress mainly the hydrogen and oxygen influxes from the vacuum wall, while the carbon and oxygen intrinsically exist in the plasma. The helium is frequently used as the working gas as well as the deuterium. The neon and argon are also often used for the radiation cooling of edge plasma to reduce the heat flux onto the divertor plate. The measured spectra were analyzed mainly based on the database of National Institute of Standards and Technology. As a result, spectral lines of He Ⅱ, Li Ⅱ–Ⅲ, B Ⅳ–Ⅴ, C Ⅲ–Ⅵ, O Ⅲ–Ⅷ, Ne Ⅱ–Ⅹ,Si Ⅴ–Ⅻ, and Ar Ⅹ–XVI are identified in EAST plasmas of which the central electron temperature and chord-averaged electron density range in Te0=0.6–2.8 keV and ne=(0.5–6.0)×1019 m-3, respectively. The wavelengths and transitions of EUV lines identified here are summarized and listed in a table for each impurity species as the database for EUV spectroscopy using fusion plasmas.

定期监测输电线路中导线弧垂的大小对输电线路的稳定运行有重要意义。传统的弧垂测量方法操作复杂且耗时较长,应用单目视觉获取完整导线图像是一种便捷的弧垂测量方法,但是当输电线路的档距过大时,相机受视场角和分辨率的限制,无法拍摄完整的导线,难以测量弧垂。针对上述问题,设计了一种便捷可用的局部摄影测量方法,将IMU中的加速度计传感器与高分辨率工业单目相机结合,在已知少量输电线路参数的条件下,只需拍摄待测导线的左侧部分即可。获得单幅导线图像后,引入语义分割技术提取图像中的导线,以摄影测量模型为基础将导线的实际点与对应成像点建立联系,以此建立非线性方程组,经非线性求解恢复导线的三维形状,进而计算导线弧垂。弧垂的测量相对误差可以控制在5%以内,满足实际应用需求。

采用氘、氚燃料的核聚变反应会产生大量的中子、γ射线及活化产物等,对人员和环境的辐射安全产生影响。为了减小电离辐射带来的影响,需要准确掌握聚变装置核辐射场强度的时间与空间分布信息。世界上已建设的磁约束聚变装置,均根据其自身运行工况特点,建立了完整的核辐射监测系统来应对电离辐射带来的潜在影响。通过对磁约束聚变装置运行及维护期间辐射剂量的监测,获得实验场所与外围环境的电离辐射和放射性核素数据,为辐射安全防护管理提供数据支撑。基于对国内外磁约束聚变装置辐射监测系统的调研,本文归纳了此类装置主要的电离辐射源项及监测系统架构,进而介绍了磁约束聚变中子与γ辐射剂量的测量方法及常用探测器。最后综述了国内外核聚变装置辐射监测系统的研究状况,展望了未来核辐射监测系统的发展趋势与目标。

为探讨城市道路污染物对路面抗滑性能的影响,模拟真实的道路情况,采用城市道路吸尘车从实际城市道路中收集污染物;利用振动摇筛机和激光粒度仪分析污染物的种类和粒径分布;在干、湿两种情况下,利用连续摩擦因数测定仪(T2GO系统)测定含有不同污染物的AC-13型沥青路面的摩擦因数.研究结果表明,砂尘类污染物是城市道路的主要污染物类型;在干燥条件下,随着砂尘类污染物的增加,路面摩擦因数逐渐降低;并且,在潮湿情况下,污染物对沥青路面抗滑性能的影响会随着污染物类型变化而发生改变;与干燥条件相比,污染物在潮湿状态下对路面抗滑性能的影响更大.

考虑诊断中性束在HT-7等离子体中的电离,复合和电荷交换,对不同靶等离子体的等离子体温度、密度和杂质含量,计算了中性束在等离子体中的衰减。分析结果表明,等离子体的密度对中性束的衰减影响较大,而温度的变化对中性束衰减影响较小。当增大时,中性束衰减率随等离子体密度显著增大;当中性束的能量增大时,中性束也衰减较甚。含杂质中性束的衰减率也增大。最后,根据诊断中性束在EAST托卡马克中等离子体衰减的计算结果,给出了EAST托卡马克中等离子体所要求的诊断中性束参数。
