走出迷雾——论田纳西·威廉斯《鬣蜥之夜》中的冲突

没有冲突就没有戏剧,戏剧冲突是戏剧的灵魂,是戏剧主题的基础和情节发展的动力,是社会生活矛盾在戏剧艺术中的集中而概括的反映。著名的美国戏剧家田纳西威廉斯的代表作品之一《鬣蜥之夜》中的丰富而富有内涵的一系列冲突有效地外化了人物心理,深刻表现了当代美国社会的精神危机这一主题,极大地增强了剧本的张力。

Tunable water-based lubrication behavior of alkyl- and fluoroalkyl-silanes

In this paper,we report the tribological properties of self-assembled molecular(SAM) films of fluoroalkylsilanes and non-fluoroalkylsilanes,with different chain-lengths,adsorbed on Si substrate surfaces by covalent bonds.The SAM films were characterized using a universal ball-disk experimental tester in aqueous solutions.The substrate surface was examined by X-ray photoelectron spectroscopy(XPS),and the SAM films adsorbed on the Si surfaces were inspected by contact angle measurements and XPS.Lubrication studies revealed that several kinds of fluoroalkylsilanes had similar friction coefficients;the small differences were attributed to the chain flexibility.In contrast,differences in the aqueous lubrication properties of SAM films of non-fluoroalkylsilanes were clearly identified.It is suggested that substitution with fluorine atoms and the surface affinities of fluoroalkylsilanes contributed to redistribution of surface changes,causing variations in lubrication behaviors.     

Continuity of solution mappings for parametric generalized set-valued weak vector equilibrium problems

This paper obtains some stability results for parametric generalized set-valued weak vector equilibrium problem. Under new assumptions, which do not contain any information about solution mappings, the authors establish the continuity of the solution mapping to a parametric generalized set-valued weak vector equilibrium problem without monotonicity. These results extend and improve some results in the literature. Some examples are given to illustrate the results.

Magnetoresistance of the thin film ferromagnetic nanoconstrictions

The magnetoresistance and I-V characteristics at different temperatures of the thin film ferromagnetic nanoconstrictions of variable width (from 20 to 250 nm) and 10 nm thicknesses, fabricated by electron beam lithography and vacuum thin film deposition are compared. The magnetoresistance and resistance of the thin film ferromagnetic nanoconstrictions are not related to the width of the nanoconstrictions. Instead the resistance of the local nano-region in the middle of the thin film ferromagnetic nanoconstriction has only a minor role compared to that of the two microscale thin film ferromagnetic electrodes, which contribute the majority of the measured resistance. The magnetoresistances of the thin film ferromagnetic nanoconstrictions and a 0.2 cm × 0.8 cm thin ferromagnetic film deposited under the same conditions were also compared; the thin film ferromagnetic nanoconstrictions have higher magnetoresistances than the thin ferromagnetic film, which implies that the measured magnetoresistance of the thin film ferromagnetic nanoconstrictions comes mainly from the local nano-region in their centers. In conclusion, the measured magnetoresistance of the whole sample is similar to the anisotropic magnetoresistance, because the resistance of the two microscale thin film ferromagnetic electrodes is much higher than that of the local nano-region in the middle of the samples. Comparing the experimental results for the thin film ferromagnetic nanoconstrictions and the thin ferromagnetic film reveals that the magnetoresistance of the local nano-region in the middle of the sample is much higher than that of the two microscale thin film ferromagnetic electrodes attached to it.
