孤立子的高度稳定性和粒子性引起了人们对孤立子的极大兴趣,并且在流体物理、固体物理、等离子体物理和光学实验中频频被发现,很多非线性发展方程都存在孤立子解。本文在符号计算的帮助下,利用一个广义的双曲函数方法,得到(2+1)维变系数... 孤立子的高度稳定性和粒子性引起了人们对孤立子的极大兴趣,并且在流体物理、固体物理、等离子体物理和光学实验中频频被发现,很多非线性发展方程都存在孤立子解。本文在符号计算的帮助下,利用一个广义的双曲函数方法,得到(2+1)维变系数Nizhnik-Novikov-Veselov方程的新的更广义类型的孤子解,此方法还可被应用到其它非线性发展方程中去。 展开更多

The term geopoetics has a wide interpretation. It is defined as a project of the cultural activity aimed at creating and changing territorial myths and research path, which considers the interaction between literary creativity and geographical space. Defining this term, it is possible to introduce a geopoetical analysis diagram based on three interconnected positions: the writer's personality, the universe of an artwork and its characters. The Last Novik--A historical novel by Lazhechnikov analysis example presented on a diagram reveals the relationship between time and space in the literary work, as well as the author's interaction with the described events. 展开更多
