劳伦斯创作的大量动物诗代表诗人成熟的诗歌艺术和较高的艺术成就.这些诗歌生动地刻画了一系列遵循自然本能、不受自我意识困扰的动物形象.动物身上所体现的存在方式展示了与人类经验世界完全不同的天真世界.然而,由于自我意识及文化传统的积淀所形成的经验性世界,人难以体验天真世界的魅力并获得动物似的独立. 相似文献

为了考察稠化剂的量对锂基润滑脂流变性的影响,在稳态剪切流和小幅振荡剪切流下测试了锂基润滑脂的流变参数。通过分析触变性、屈服应力,表观黏度、储存模量和应变幅度等流变参数,探讨了稠化剂的量对流变性的影响。结果表明:随着稠化剂含量增加,锂基润滑脂的黏弹性表现更加显著,其结构更加稳定。 相似文献

As an excellent anti-wear and friction-reducing additive, nano-copper has attracted extensive researches and attention in tribology field. However, the existing researches are still limited to zero-dimensional nano-copper, that is, the effect of copper nanoparticles on the tribological properties of lubricants. In this paper, the effects of nano-coppers with different dimensions (copper nanoparticles, copper nanowires and copper nanoplates) on the anti-wear ability and friction-reducing performance of lithium grease were systematically investigated. And the mechanism of interaction between dimension and tribological properties was explained in detail. It is concluded that the tribological properties of lithium grease can be improved by the addition of nano-coppers with different dimensions and the dimension of nano-copper has great influence on its tribological property. 相似文献
