以教材、教学内容建设为核心创建国家级精品课程"热学" 总被引:1,自引:0,他引:1
国家级精品课程“热学”的主要特色是:在教材和教学内容上的“实、新、宽、活”,强调规律与科学前沿以及自然科学有关现象联系,强调物理思维方法训练;在教学方法上开设讨论课,并且把课堂讲授和课堂讨论、课外阅读、学生小论文四者结合,它们都以教材为依托. 相似文献

本文基于“新工科”对新形势下人才培养目标的要求,以“热学”课程为依托,进行“绿色工程”教育的教学改革探索。本文首先厘清“新工科”与“绿色工程”教育之间的关系。随后以此为指导,梳理“热学”课程教学内容,在遵循“完整性”“普遍性”原则的基础上,进行课程案例库的开发与建设。最后将案例库用于教学改革实践活动,经受学生的检验。教学效果表明,这一改革既符合“新工科”的宗旨,又践行了“绿色工程”理念,使学生持有获得感的同时,满意度也得以持续保证。 相似文献

The vibrational absorption bands associated with some types of double thermal donors (TD) in Ge enriched with the oxygen isotopes 16O and 18O have been identified. The thermal donors were formed during heat treatment of Ge:O crystals at 300 and 350°C. Absorption spectra were measured at room temperature and at 10 K. The formation of the thermal donors was accompanied by the appearance of three absorption bands, which in the Ge:16O spectra at room temperature are located at 600, 740, and 780 cm–1. In low-temperature measurements, the bands at 600 and 780 cm–1 exhibited splitting into series of narrow lines (up to 9) associated with some types of thermal donors (TD1–TD9). The absorption spectra measured at 10 K after different cooling conditions display bistability of the first four types of thermal donors (TD1–TD4). In the samples cooled by illumination with light in the region of frequencies of the fundamental absorption of Ge, pairs of lines are observed that belong to the bistable thermal donors in the helium-like configuration of double donors (DD). After cooling the samples in the dark, these pairs of lines are replaced by three new bands, which belong to local vibrational modes of bistable thermal donors in the low-energy neutral configuration. Based on the isotopic shift of the local vibrational modes of the thermal donors in Ge:16O and Ge:18O, a rigorous proof of the oxygen atoms entering into the composition of thermal donors is obtained. 相似文献

针对升力体外形飞行器局部构件干扰流动及热环境影响,采用理论分析、数值模拟、工程半经验模型及实验数据分析相结合,研究高速流动条件下平板表面突起物干扰区气动加热影响.对比分析不同外形特征下突起物对流场结构的影响表明:干扰区热环境分布与流动结构直接相关,压力比拟方法可在局部区域可靠预测热流分布;高台类突起物干扰区范围和热环境敏感依赖于其有效宽度,而低台类突起物干扰区范围和热环境则主要依赖于高度变化;方形头构件与圆形头构件对称面干扰区范围相差1.414倍(湍流/层流均成立);后掠角存在对干扰区范围影响显著,给出后掠角对干扰区的影响关系式.研究结果可方便地用于飞行器热环境预测中,为其提供技术支撑. 相似文献

Spectroscopic study of local thermal effect in transparent glass ceramics containing nanoparticles 下载免费PDF全文
Local thermal effect influencing the fluorescence of triply ionized
rare earth ions doped in nanocrystals is studied with laser
spectroscopy and theory of thermal transportation for transparent
oxyfluoride glass ceramics containing nanocrystals. The result shows
that the local temperature of the nanocrystals embedded in glass
matrices is much higher than the environmental temperature of the
sample. It is suggested that the temperature-dependent thermal energy
induced by the light absorption must be considered when the theory of
thermal transportation is applied to the study of local thermal
effect. 相似文献

We study thermal spin squeezing (TSS) and thermal global entanglement (TGE) in a general Heisenberg spin chain, in the presence of Dzyaloshinskii-Moriya interaction and an external magnetic field. We derive an inequality associating the squeezing parameter and the global concurrence, which establishes (TSS) as a signature of (TGE). The inequality reduces to equality for particular symmetric chains which also associates TSS with bipartite entanglement in such systems. We also check the results by presenting two numerical examples. 相似文献
