Abstract: The title compound, C19H31O2P, features a distorted tetrahedral P atom that bonds to the phenyl ring, isopropyl and 2-isopropyl-5-methylcyclohexyl groups, and is determined as having an Rp configuration. A chair conformation is observed for the cyclohexyl ring. In the crystal, molecules are linked into chains running along the a axis by weak intermolecular C—H...O hodrogen bonds.

Abstract: In the title compound, C20H34NO2P, the P atom has an irregular tetrahedral environment and exhibits Sp chirality. In the crystal, weak intermolecular N—H...O and C—H...O hydrogen bonds link the molecules into chains extending in [010].
2-Isopropyl-5-methylcyclohexyl N-cyclohexyl-P-phenylphosphonamidate
Fan-Jie Meng,Hao Xu,Li-Juan Liu,Daqi Wang
Acta Crystallographica Section E , 2010, DOI: 10.1107/s1600536810032319
Abstract: The title compound, C22H36NO2P, features a P atom bonded to a phenyl ring, a cyclohexylamine unit and the O atom of a menthyl group. In the crystal structure, intermolecular N—H...O hydrogen bonds connect molecules into a one-dimensional chain in the b direction.
catena-Poly[[tetrakis(μ-pentafluorobenzoato-κ2O:O′)dimolybdenum(II)]-μ-4,4′-bipyridine-κ2N:N′]
Li-Juan Han
Acta Crystallographica Section E , 2011, DOI: 10.1107/s1600536811031734
Abstract: In the title compound, [Mo2(C7F5O2)4(C10H8N2)]n, the molecule forms a paddle-wheel-type structure. Each Mo24+ unit is equatorially coordinated by four pentafluorobenzoate groups, while the axial positions are occupied by two 4,4′-bipyridine molecules. The Mo—Mo bond length of 2.1227 (4) is representative of a dimolybdenum quadruple bond. An infinite linear chain parallel to [110] is formed by the Mo24+ unit coordinating axially to the two N atoms of the 4,4′-bipyridine ligand [Mo—N = 2.594 (2) ]. The crystal packing shows molecules linked together into a three-dimensional network via Mo—N coordination interactions and weak π–π stacking interactions between perfluorophenyl rings [centroid–centroid distance = 3.7280 (3) and centroid-to-plane distance = 3.6103 (12) between two pentafluorophenyl rings].
5-Butylamino-2-[2-(dimethylamino)ethyl]-1H-benz[de]isoquinoline-1,3(2H)-dione
Li-Juan Xie
Acta Crystallographica Section E , 2010, DOI: 10.1107/s1600536810018702
Abstract: The title compound, C20H25N3O2, is a new amonafide analogue, which exhibits antitumor activity. The asymmetric unit contains two molecules with similar conformations for the substituted aliphatic chains. The two independent molecules form dmers through N—H...N hydrogen bonds. The crystal structure is stabilized via π–π stacking interactions, the shortest centroid–centroid separation between six-membered rings being 3.673 (2) .
Tetrakis(μ-pentafluorobenzoato-κ2O:O′)bis[(tetrahydrofuran-κO)molybdenum(II)]
Li-Juan Han
Acta Crystallographica Section E , 2011, DOI: 10.1107/s1600536811033411
Abstract: In the asymmetric unit of the title compound, [Mo2(C7F5O2)4(C4H8O)2], two independent half-molecules are present, which are completed by a crystallographically imposed center of inversion between the individual Mo atoms. In each molecule, four pentafluorobenzoate anions bridge the quadruply bonded Mo24+ unit that is, in addition, axially coordinated by two O atoms of tetrahydrofuran (THF) molecules. In the two independent molecules, the mean Mo—Mo bond length is 2.110 . Since the THF molecules are equally disordered over two sets of sites, there are four different Mo—O distances in both half-molecules with an overall mean of 2.542 . A zigzag chain is formed by π–π stacking interactions between pentafluorophenyl rings, indicated by a centroid–centroid distance of 3.7054 (11) and a centroid-to-plane distance of 3.4169 (3) . The extension of the unit gives a three-dimensional network structure with the THF molecules located in the voids.
Modeling on the breakup of visco-elastic liquid for effervescent atomization
Qian Li-Juan
Thermal Science , 2012, DOI: 10.2298/tsci1205446q
Abstract: A primary atomization model for visco-elastic liquid is established based on the ligament formation assumption and dispersion relationships. Two linear instability analyses are used in presented paper. Both of them are involved in the primary atomization model and the calculated results are compared with published experimental data. After validation, the model is used to predict the effects of various operating conditions and visco-elastic liquid physical properties on atomization performance.
Appreciation of Meng Haoran’s Chun Xiao and Its English Versions: a Text Linguistic Point of View
Li-juan HUANG
Cross-Cultural Communication , 2007, DOI: 10.3968/635
Abstract: Text linguistics, with its ground-breaking theories and methodology, provides readers not only an opportunity to better understand the original text, but also a sound theoretical basis for the appreciation and criticism of its versions. This article thus conducts a study on Meng Haoran’s well-known poem Chun Xiao and its different versions from the perspective of Chinese-English contrastive discourse analysis, taking cohesion and coherence as its major references and criteria. It is aimed to offer some inspiration for the Chinese-English contrastive study as well as translation studies. Key words: text linguistics, English version of Chun Xiao, cohesion, coherence, translation Criticism Résumé: La linguistique du texte est une discipline jeune dont la théorie et la méthode d’analyse aident non seulement le lecteur à mieux comprendre le texte original, mais aussi lui fournir le fondement théorique pour l’appréciation et la critique de la traduction. L’article présent, dans la perspective de l’étude comparative des textes chinois et anglais, en se référant aux deux caractéristiques les plus fondamentales de la linguistique du texte - cohérence et continuité, tente de procéder à des recherches sur le poème L’Aube du printemps de Meng Haoran et ses traductions dans le but d’aider à l’étude comparative des textes chinois et anglais ainsi que les recherches de traduction. Mots-clés: linguistique du texte, version anglaise de L’Aube du printemps, cohérence, continuité, critique de traduction 摘要:語篇語言學是一門新興的學科,其主要理論與分析方法不僅能幫助讀者更好地理解原文,同樣也為其進行譯作的欣賞與批評提供理論基礎。本文擬從漢英語篇對比研究的視角出發,以銜接與連貫這兩個作為語篇語言學最重要的特徵為標準與參照,對孟浩然的《春曉》一詩及其譯本展開嘗試性的探討,目的在於為漢英對比研究與翻譯研究提供一點啟發。 關鍵詞:語篇語言學:《春曉》英譯;銜接;連貫;翻譯批評
A Probabilistic Approach for Gradient Inequalities on Time-Inhomogeneous Manifolds
Li-Juan Cheng
Mathematics , 2013,
Abstract: Gradient inequalities of the Hamilton type and the Li-Yau type for positive solutions to the heat equation are established from a probabilistic viewpoint, which simplifies the proofs of some results of Sun [{\it Pacific J. Math.}, 253 (2011), pp. 489--510].
