Measurement of the A-Value of the Intersystem Transition in Al II at 2670 Å: Å Progress Report [PDF]
International Astronomical Union Colloquium, 1984 Ratios of intensities of spectral lines produced in the radiative decay of collisionally-excited levels of atomic ions are versatile indicators of electron density in astrophysical plasmas when one of the lines involves a metastable level (see the review by Feldman 1981 and references therein). Radiative transition probabilities (A-values) and electron

Optical spectrum of the post-AGB Star HD56126 in the wavelength interval 4010-8790 Å Å [PDF]
Astrophysical Bulletin, 2007 The optical spectrum of the post-AGB star HD56126 identified with the infrared source IRAS07134+1005 is studied in detail using high spectral resolution observations (R = 25000 and 60000) performed with the echelle spectrographs of the 6-m telescope. A total of about one and a half thousand absorptions of neutral atoms and ions, absorption bands of C2,

Onomázein, 2023 Because the Chinese kinship and the Spanish one belong to the Sudanese type and Eskimo type respectively, there is a huge asymmetry and non-equivalence in the address terminologies. Although the Chinese kinship address terms, like the Spanish ones, have vocative function in the family context as well as in the non-family one, for the linguistic and ...

, 1992 问题“启动效应”是近年来认知心理学研究的重要课题。研究启动效应的价值在于可以通过它探讨人脑内各种文字和知识信息是如何表征的。按“激活扩展”理论,人脑中存储的各种文字信息、知识概念是以一定的关系网络形式组织的。启动效应就是外部输入信号(启动词出现)沿着大脑中的这种记忆网络结构扩展,激活网络中各个结点使它们处于活跃状态的结果 ...

, 2018 含蜡原油是一种组成复杂的混合物,析蜡点以下常表现为复杂的非牛顿流体特性,而其中含蜡原油所具有的屈服应力特性,对管道输运系统中的停输再启动具有重要的影响。本文研究中,为系统的分析含蜡原油屈服应力特性在管道停输再启动过程中的作用,将对含蜡原油的屈服应力进行直接测量,并结合管道输运的模拟对停输再启动现象进行系统的分析。实验中,采用HAAKE RS6000旋转流变仪对含蜡原油的屈服应力进行直接测量,分别考虑温度和剪切速率等因素的影响。同时,建立含蜡原油管道输运模拟系统,对其启动过程进行测试分析 ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT Although the use of AI technologies (e.g., chatbots and automated writing evaluations (AWE)) has gained considerable attention in language learning fields in recent years, how AI technologies have been designed and implemented in language learning education, as well as their effectiveness, is understudied.

International Journal of Applied Linguistics, EarlyView.ABSTRACT This study examines how foreign language teachers’ beliefs about the medium of instruction and translanguaging evolve over time by revisiting three in‐service teachers twelve years after their initial interviews. Using a qualitative longitudinal design, the study traces how translanguaging was initially framed as pedagogically deficient but ...

, 2014 针对多通路并联回路板式脉动热管搭建试验台,选用无水乙醇作为工质,在不同的充液率、倾斜角度和加热功率情况下,观测工质的流型以及流动方式的变化,分析脉动热管的启动特性。结果表明,工质的流型为泡状流,汽液塞间隔分布的塞状流,塞状流与环状流并存的混合流,整个通道中不存在完全是环状流的流型;充液率为10%时,工质主要分布在脉动热管的中间部位,充液率为35%~85%,工质分布的均匀性增强;运行过程中工质以塞状流(靠近冷凝端)和环状流(靠近加热端)并存的混合流形式存在,随着加热功率的增加 ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT While English‐medium instruction (EMI) and English for Academic Purposes (EAP) courses are designed to promote language and content learning, their prevailing English‐only approaches often undermine students’ learning motivation. Against this backdrop, translanguaging has gained recognition as an effective pedagogical practice to support ...
