Effect of isothermal aging on the microstructure and properties of as-cast Mg–Gd–Y–Zr alloy
No full textThe microstructure of Mg–7Gd–3Y–0.4Zr (wt.%) alloy during isothermal aging at 200 °C, 225 °C and 250 °C was investigated using optical microscopy (OM), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray diffraction. The mechanical properties of the peak-aged materials were evaluated by using Vickers hardness values, and their corrosion resistance was studied by using immersion tests, salt spray tests and electrochemical measurements in 5% NaCl solutions (wt.%). The results show that owing to the existence of a great many β′ precipitates with a quite small size and uniform distribution in the matrix, optimal mechanical properties and good corrosion resistance in 5% NaCl solutions are obtained when the alloy is aged at 200 °C for 120 h. The potentiodynamic polarization curves show that the corrosion current densities of the cathodic hydrogen evolution on the alloy peak-aged at 200 °C is lower than those for specimens of the alloy aged at 225 °C and 250 °C, which agrees fairly well with the microstructures of the alloys

Tang Code, Tang Rite, and Other Manuscripts of Tang Dynasty
No full textIn the present paper, the author gives the preliminary reports on three newly found Tang 唐 official documents, pointing out their important value, and offering the all texts for further studies.1. In Tunhuang and Turfan Documents concerning Social and Economic History I. Legal Texts (Tokyo 1978-1980), Professors T. Yamamoto, O. Ikeda, and M. Okano published the joined texts of O. 5098 and O. 8099 from Otani collection. They identified the fragments with the Section on Violence and Robbery of the Tang Code (唐律), and pointed out the article comes from the Yonghui 永徽 or Chuigong 垂拱 Code according to the Zetian 則天 characters used in the Buddhist text on the verso. The author joins another fragment based on an old photograph of the Turfan document preserved in the Lüshun Museum (旅順博物館). The new text contains one different article from the printed text after the Song 宋 dynasty.2. Among the Dunhuang 敦煌 manuscripts in the National Library of China in Beijing, there is a good copy of the Tang Rite (唐礼) in high Tang characters (No. zhou 周 70A). It contains the text corresponding to the Da Tang Kaiyuan li 大唐開元礼, vol. 37: “Huangdi shixiang yu Taimiao 皇帝時享於太廟”. It is the first time to find the book in Dunhuang or Turfan manuscripts.3. In his Dunhuang Turfan Tangdai fazhi wenshu kaoshi 敦煌吐魯番唐代法制文書考釈, Liu Junwen thought the document of zhou 51 should be the Regulations of the Regional Military Organization. But the form of the original document could not conform to the Tang Regulations, so the author refutes his view and thinks that it is an official document relating to the beacon of the military fortress in the area of Dunhuang or Turfan.journal articl

Reinventing the Pre-Tang Tradition: Compiling and Publishing Pre-Tang Poetry Anthologies in Sixteenth-Century China
No full textAbstract
This article examines how the making of pre-Tang poetry anthologies in sixteenth-century Ming China led to a reinvention of the pre-Tang poetic tradition. From the Zhengde period 正德 (1506–21) well into the Wanli reign 萬曆 (1573–1620), the compilation and publication of new pre-Tang poetry anthologies saw a dramatic increase, making the anthologizing practices in the 1500s crucial to understanding the pre-Tang tradition. Through a study of paratextual elements (book titles, tables of contents, prefaces, postscripts, etc.) in twenty-two pre-Tang poetry anthologies compiled in the 1500s, this article identifies three types of anthologizing practices. By employing quantitative and network analysis, the author hopes to historicize these practices, investigate the motivations for the anthologies, and explore their citation networks. These anthologizing practices, I conclude, gradually transformed the classification principles of previous anthologies, expanded the scope of canonized anthologies, and established a distinct pre-Tang tradition by the end of the sixteenth century.</jats:p
The Value Pursuit of the Theoretical System of Socialism With Chinese Characteristics: Serving the People – Taking Deng Xiaoping Thought of Serving the People as an Example
No full text“The free and comprehensive development of people”: is the value pursuit of Marxism, and is also the ultimate goal of socialist and communist development. The theory of Deng Xiaoping also regards people’s development as the goal of its value pursuit, which is of more Chinese characteristics - serving the people. This is not only the inheritance of the Marxism-Leninism, but also the inheritance of the thought of Mao Zedong, which also provides the logical origin for value pursuit of the theoretical system of Socialism with Chinese characteristics. Deng Xiaoping Theory of serving the people becomes the bridge which connects Marxism-Leninism, the thought of Mao Zedong and the theoretical system of Socialism with Chinese characteristics, and lays a foundation for the construction of socialism with Chinese characteristics
Fabrication of nano-structured super-hydrophobic film on aluminum by controllable immersing method
No full textAluminum alloy surface can be etched easily in acid environment, but the microstructure of alloy surface hardly meets the customers’ demand. In this work, a facile acidic-assistant surface oxidation technique has been employed to form reproducible super-hydrophobic surfaces on aluminum alloy plates. The samples immersed in three different acid solutions at ambient temperatures are studied and the results demonstrated that the aqueous mixture solution of oxalic acid and hydrochloric is easier to produce better faces and better stability. Scanning electron microscopy (SEM), X-ray diffraction (XRD), Raman spectrometer, X-ray photoelectron spectroscopy (XPS) and water contact angle measurement are used to investigate the morphologies, microstructures, chemical compositions and hydrophobicity of the produced films on aluminum substrates. The surfaces, configured of a labyrinth structure with convexity and concavity, are in different roughness and gloss because of the different recipe acid solutions used. Better roughness of the surface can be obtained by adjusting the concentration of Clˉ and oxalate ions in acid solutions. The present research work provides a new strategy for the controllable preparation super-hydrophobic films of general materials on aluminum alloy for practical industrial applications
The wine theme in Tang dynasty poetry
No full textBakalaura darba tēma ir “Vīna tēma Tan dinastijas poēzijā”. Šī tēma bija izvēlēta sakarā
ar vīna poēzijas izpētīšanas deficītu. Vīns vienmēr aizņēma svarīgu vietu ķīniešu sociālajā
dzīvē, un it īpaši šis dzēriens bija vispusīgi izmantots Tan dinastijā. Vīna tēmai ir veltīts
milzīgs Tan dzejoļu skaits, bet joprojām šī tēma nebija rūpīgi izpētīta.
Šī bakalaura darba mērķis ir nodemonstrēt, ka vīna tēma Tan dinastijas poēzijā ir tik pat
svarīga kā citas tēmas. Autore studē vīna nozīmi Tan dinastijā un pirms-Tan periodā, akcentē
galvenos Tan poēzijas aspektus, izpētē kādā veidā vīna tēma kļuva par poēzijas sastāvdaļu,
noteic galvenos dzeršanas motīvus poēzijā un analizē slavenu Tan dzejnieku-dzērāju vīna
poēziju.
Atslēgvārdi: Ķīna, Tan, dzeja, vīns.The theme of the bachelor paper is “The wine theme in the Tang dynasty poetry”. The
choice of this theme was determined by the deficit of research on wine poetry. Wine has
always played an important role in Chinese social life, and especially it found an extensive
use in the Tang dynasty. The wine theme takes up a great number of Tang poems, however, it
is not a topic which is studied in depth.
The aim of this bachelor paper is to demonstrate that the wine theme in Tang poetry is
as important as the other themes. The author studies the meaning of wine in the Tang dynasty
and the pre-Tang period, shows the main aspects of Tang poetry, researches how the wine
theme became a part of poetry, ascertains the main drinking motives in poetry and analyzes
wine poetry of the most famous Tang poets-drinkers.

Measurements of male: BL: 14.2 mm, FL: 7.7 mm. HL: 2.06 mm, HW: 2.18 mm, EYL: 0.59 mm, TL: 1.00 mm, PL: 2.88 mm, PW: 2.55 mm, EL: 2.89 mm, EW: 2.95 mm. HW/HL: 1.05, TL/EYL: 1.69, PL/PW: 1.13, EL/EW: 0.98. Body entirely blackish with metallic blue tint,appendages reddish except mid and hind coxae darker. Head 1.05 times as wide as long, rounded quadrangular, posterior angles entirely rounded, tempora longer than eyes (ratio 1.69), disc with punctation well delimited on middle portion and more or less confluent on lateral portions, posterior half of head with impunctate midline, interstices densely reticulated, about equal to diameter of punctures on midanterior portion and mostly narrower than half diameter of punctures on the remaining portions. Pronotum 1.13 times as long as wide, widest at about basal third, disc with complete impunctate midline, punctation confluent, interstices reticulated, narrower than half diameter of punctures; scutellum with black pubescence, finely and densely punctate. Elytra 0.98 times as long as wide and as long as pronotum; punctation fine and dense, interstices slightly dull with coarse granulose microsculpture. Abdomen semi-cylindrical, posterior margin of tergite VII with palisade fringe; posterior basal line of abdominal tergites III–V distinctly bisinuate, median impression after posterior basal line relatively shallow; punctation dense and fine, interstices reticulated. Male. Sternite VIII emarginate at middle of posterior margin; sternite IX (Fig. 19) emarginate medioapically; tergite X(Fig. 20) subtriangular with apex obtusely pointed. Aedeagus (Fig. 21) with median lobe asymmetrical, apical portion hook-like and pointing to left side in ventral view, paramere slightly asymmetrical, slightly shorter than median lobe, underside of paramere (Figs 22, 23) with a few sensory peg seta in apical portion and one degenerated sensory peg seta at middle of subapical portion. Female. Unknown. Differential diagnosis. The new species is similar to S. cardinalis Smetana, 2010 from Sichuan and Yunnan, but can be distinguished from the latter by the posterior angles of the head being rounded (slightly prominent in S. cardinalis), the posterior half of the head with the impunctate midline broad (narrow in S. cardinalis), the apical portion of the aedeagal median lobe hook-like, and the underside of the paramere with sparser sensory peg setae. Both species seem to differ also in the degree of metallic tint in some cases (compare Figs 5 and 26), but this character seems to be variable in S. cardinalis which can also exhibit a bluish-purple tint (A. Smetana, pers. comm. 2020) and the coloration is hence not useful as a diagnostic character. The new species is also a little similar to S. smetanai described above in coloration, but it can be distinguished by the head with an impunctate midline, the elytra distinctly longer, and the abdomen distinctly darker in coloration. Etymology. This species is named in honor of Mr. Lie Ning who accompanied the second author during the collecting trip. Distribution. China (Yunnan).Published as part of Zhao, Xin & Tang, Liang, 2020, Three new species of the genus Sphaerobulbus from China (Coleoptera: Staphylinidae), pp. 333-341 in Acta Entomologica Musei Nationalis Pragae 60 (1) on pages 337-338, DOI: 10.37520/aemnp.2020.019, http://zenodo.org/record/387994
