从定语位置看空间维度词“大”的隐喻拓展

本文尝试从定语位置对空间维度词"大"进行语义分类,运用认知语言学隐喻理论分析"大"由空间始原域向数量规模、力量程度、年龄、时间和社会地位目的域的隐喻映射路径,探讨通过"量"的相似性原则"大"借用空间概念来构造其他非空间概念,揭示隐喻作为认知工具在语言发展中的重要作用。

情绪隐喻的取象与文化认知

在文化语言学和认知语言学的框架下,情绪隐喻生成于身体本能反应、空间概念映射、物性特征迁移、社会文化四条途径。身体本能禀赋先天遗传特征,是情绪隐喻的第一来源。空间概念投射于情绪域源于人类的空间思维定势。物性迁移隐喻取象自事物与心灵之间相似性的隐性概念结构。另外,不同的文化形态衍生不同的情绪概念。

Formation mechanism and oxidation behavior of MoSi_2-SiC protective coating prepared by chemical vapor infiltration/reaction

In order to protect C/C composites from oxidation, SiC-MoSi2 composite coating was synthesized by chemical vapor infiltration /reaction （CVI/CVR） technology. A porous Mo layer was prefabricated on SiC coated C/C composites, and then MoSi2 and SiC were subsequently prepared in a CVI /CVR process using methyltrichlorosilane （MTS） as precursor. The deposition and reaction mechanism of the MoSi2-SiC composite coating was investigated by X-ray diffraction （XRD） and scanning electron microscopy （SEM）. The oxidation behavior of SiC-MoSi2 coated specimens was tested. The results show that the porous Mo layer can be densified with SiC phase decomposed from MTS, and transformed into SiC-MoSi2 by reacting with MTS as well. A dense composite coating was prepared with optimized deposition parameters. The coated specimen exhibits a good oxidation resistance with a little mass loss of 1.25% after oxidation at 1500 °C for 80 h.

Screening of Deltamethrin Resistant Strain of Bombyx Mandarina

[ Objective ] The aim of the study was to explore the resistance development of deltamethrin through selection of dettamethrin resistant strain of wild silkworm （ Bombyx Mandarina）, thus providing the basis for scientific pesticide application and resistance management. [ Method] The wild silkworms collected from three different regions were reared indoors, and the sensitivity of their parents to deltamethrin was detected by topical application. The larvae in each generation were treated with deltamethdn in median lethal dose or so by.topical application. The mortality of larva was analyzed for the establishment of toxicity regression equations and the calculation of the multiple or increased multiple of deltamethdn resistance.[Result] After the Qidong Bornbyx Mandarina （YQD） fed with mulberry leaves were selected for three generations indoors, the multiple of deltamethdn resistance of F, was 14.26, 1.2 times as great as that of Fo ; after the Bombyx Mandarina from mulberry garden of Soochow University （YSD） fed with mulberry leaves were selected for three generations indoors, the multiple of deltamethrin resistance of F4 was 16.48, 1.9 times as great as that of Fo ; after the Wujiang Bombyx Mandarina （YWJ） fed with artificial diets were selected for three generations indoors during six generations, the multiple of deltamethrin resistance of Fe was 18.67, 1.2 times as great as that of Fo. [ Conclusioa] With the selection in same dose, the resistance multiple of YSD increases more rapidly than that of YQD; under double selection of artificial diets and insecticide, the resistance multiple of YWJ increases more slowly than that of YQD.

经学宗旨 文学阐释——《诗经原始》探源

《诗经原始》是方玉润诗经研究的代表著作,是其主要特点是用文学阐释来进行《诗经》经学宗旨的探究。方氏把《诗经》作为文学文本进行解读,意在通过对《诗经》字句疏证与诗学分析的沟通中追求自悟和新解,并将多种文学批评方法引入对《诗经》的研究中,主张从文学欣赏的角度,从谋篇布局、艺术方式上探究《诗经》的原始旨意。但《诗经原始》以"原诗人始意"为根本宗旨,本质上仍然是一部经学著作。值得注意的是,这种经学与文学相结合的研究手法,代表了嘉道时期《诗经》学研究的新取向,为《诗经》学的研究开辟了崭新的领域。

Summer-autumn habitat use by Galliformes in a primary forest,southeastern Tibet

Habitat use by Galliformes in an ornithologically unexplored region,a forest area in southeastern Tibet,was investigated during the summer and autumn periods of 1995.A total of seven species were recorded,most of which preferred habitats on south-facing slopes and avoided those on north-facing slopes where conditions were relatively humid.A hybrid population of White (Crossoptilon crossoptilon) versus Tibetan Eared-pheasants (C.harmani) was predominant among the Galliforme community,followed by Blood Pheasants (Ithaginis cruentus) and Chinese Grouse (Bonasa sewerzowi).A further investigation in 2001 showed that on account of little human activity in the distant primary forests,the birds suffered less of a threat from hunting and habitat disturbance.

Effect of hot extrusion and heat treatment on microstructure of nickel-base superalloy

Effects of hot extrusion (HEX) and heat treatment on prior particle boundary (PPB), MC carbides,γ′precipitates and grain size of nickel-base FGH96 superalloy were studied. The results show that PPB consists of largeγ′, MC carbides enriched with Ti, Nb and a modicum of oxides. Thereafter, it can efficaciously tune γ′ precipitate size from micrometer down to nanometer region and simultaneously results in the annihilation of PPB by HEX process. The activation energy for grain growth of as-HEXed FGH96 superalloy was measured to be 402.6 kJ/mol, indicating that γ′ precipitate serves the critical role in inhibiting grain growth under sub-solvus heat treatment. Moreover, the results reveal that grain growth is primarily restrained by MC carbide in the case of super-solvus temperature.

Decoding the Homosexuality of Western Culture in Archetypal Approach

Homosexuality is a special part of western gender studies, which has been studied by western intellectual ever since it was born. Owing to the different attitudes of various cultures in different spatial-times, it was more depressed rather than accepted, but as an objective being in histor）; it shows itself a static state accompanying the whole human history. Today homosexuality has been one of the mainstreams in western intellectual movement and it is vitally important for us to give it a reasonable, precise definition in order to build up a harmonious society. This article tries to break through the bondage of material determinism and economical monism. It will be guided by the principle to delve into the human sub-consciousness to find the same essence between homosexuality and heterosexuality, to trace back to the origin of homosexuality in archetypal approach in order to reveal the anxiety of the legality of human existence and its poetic construction, which is hidden behind the cultural phenomenon.

Identification of Taxus cuspidata Sieb.et Zucc endophytic fungi─ new recorded-genus-species of China and the metabolite

A total of 94 isolates of endophytic fungi were isolated from the bark of 200-yr.-old Taxus cuspidata Sieb. et Zucc. in the primeval forest of the Changbai Mountain Natural Reserve, and 19 species of endophytic fungi were identified. Among the taxa 2 new species and 1 new varied species as well as the 6 known species of China had been described in a previous article published on Journal of Forestry Research, Vol. 14 (4): 290-294 (2003). This paper made a detail description on the morpho-logical characteristics of the 9 new recorded-genus-species and 1 new record species with illustrations, including Staphy-lotrichum coccosporum Meyer et Nicot, Botryodema lateritium Papendoorf & Upadhyay, Oedocephalum glomerulosum (Rul-liard) Sacc., Trichosporonoides oedocephalis Haskins & Spencer, Beniowskia sphaeroidea (Kal Chbrenner et Caeke) Mason, Thermomyces verrucosus Pugh, Blakeman & Morgan-jones, Gilmaniella humicola Brron , Arthrinium sphaerosperma (Per.:Fr.) Ellis, Ambrosiella brunnea (Verrall) Batra, and Cytosporina notha Diedz (1 new record species). And the habitats, hosts, distribu-tions and fruiting periods were recorded for the new recorded-genus-species. The determination result of thin layer chroma-tography (TLC) showed that the liquid fermentation metabolites of the strains could not react positively with taxoids developer - the vanillic aldehyde and dilute bismuth potassium iodide.

Derivatives of 3（5）,4-Dinitropyrazole as Potential Energetic Plasticisers

The development of a pseudo-one pot synthesis of 3（5）,4-dinitropyrazole enabled us to use it as a starting material for energetic plasticisers. Its acidic proton allowed simple derivatisation on one of the ring nitrogens. The thermal characteristics of two derivatives were evaluated. For instance, the N-allyl compound was a liquid with very low glass transition temperature, whereas the N-propargyl compound was a sticky solid at ambient temperature. The two compounds were both thermally stable according to STANAG 4582.

Postembryonic Development of Electrophysiological Characteristic of Primordial Hippocampus in Bufo bufo gargarizans

[Objective] The aim was to probe into developing changes of spontaneous electrical activities of primordial hippocampus in Bufo bufo gargarizans in postembryonic phase. [Method] Microelectrode technique was used to record extracellularly spontaneous electrical activities of neurons in primordial hippocampus of B.bufo gargarizans in postembryonic phase. [Result] Single, consecutive single, burst, consecutive burst and anomalous spontaneous firing were recorded in primordial hippocampus, in which four kinds of spontaneous firings were recorded in forepart of postembryonic development except the anomalous spontaneous firing, and the burst spontaneous firing and consecutive burst spontaneous firing were predominant. The five kinds of spontaneous firings mentioned were recorded in anaphase of postembryonic development and the single and burst spontaneous firing were predominant.Following with the development of primordial hippocampus, the amplitudes of action potential of single firing and consecutive firing enhanced gradually, and it reaches the maximum in the metamorphosis phase; the differences of the frequencies of consecutive single firing and consecutive burst firing were not significant. [Conclusion] Following with the development of primordial hippocampus, the neuronal electrical activities showed diversification, the developmental degree of the primordial hippocampus in the metamorphosis phase was close to the subadult and adult.

In vitro assessment of gastrointestinal viability of two photosynthetic bacteria,Rhodopseudomonas palustris and Rhodobacter sphaeroides

The objectives of this study were to assess the potential of two photosynthetic bacteria （PSB）, Rhodopseudomonas palustris HZ0301 and Rhodobacter sphaeroides HZ0302, as probiotics in aquaculture. The viability of HZ0301 and HZ0302 in simulated gastric transit conditions （pH 2.0, pH 3.0 and pH 4.0 gastric juices） and in simulated small intestinal transit conditions （pH 8.0, with or without 0.3% bile salts） was tested. The effects of HZ0301 and HZ0302 on the viability and permeability of intestinal epithelial cell in primary culture of tilapias, Oreochrornis nilotica, were also detected. All the treatments were deter- mined with three replicates. The simulated gastric transit tolerance of HZ0301 and HZ0302 strains was pH-dependent and correspondingly showed lower viability at pH 2.0 after 180 min compared with pH 3.0 and pH 4.0. Both HZ0301 and HZ0302 were tolerant to simulated small intestine transit with or without bile salts in our research. Moreover, there was no significant difference （P〉0.05） among three treatments including the control and the groups treated with HZ0301 or HZ0302 both in intestinal epithelial cell viability and membrane permeability, showing no cell damage. In summary, this study demonstrated that HZ0301 and HZ0302 had high capacity of upper gastrointestinal transit tolerance and were relatively safe for intestinal epithelial cells of tilapias.

Minimally invasive treatment of pancreatic necrosis

AIM: To systematically review these minimally invasive approaches to infected pancreatic necrosis. METHODS: We used the MEDLINE database to investigate studies between 1996 and 2010 with greater than 10 patients that examined these techniques. Using a combination of Boolean operators, reports were retrieved addressing percutaneous therapy (341 studies), endoscopic necrosectomy (574 studies), laparoscopic necrosectomy via a transperitoneal approach (148 studies), and retroperitoneal necrosectomy (194 studies). Only cohorts with at least 10 or more patients were included. Non-English papers, letters, animal studies, duplicate series and reviews without original data were excluded, leaving a total of 27 studies for analysis. RESULTS: Twenty-seven studies with 947 patients total were examined (eight studies on percutaneous approach; ten studies on endoscopic necrosectomy; two studies on laparoscopic necrosectomy via a transperitoneal approach; five studies on retroperitoneal necrosectomy; and two studies on a combined percutaneous-retroperitoneal approach). Success rate, complications, mortality, and number of procedures were outcomes that were included in the review. We found that most published reports were retrospective in nature, and thus, susceptible to selection and publication bias. Few reports examined these techniques in a comparative, prospective manner. CONCLUSION: Each minimally invasive approach though was found to be safe and feasible in multiple reports. With these new techniques, treatment of infected pancreatic necrosis remains a challenge. We advocate a multidisciplinary approach to this complex problem with treatment individualized to each patient.
