关于叙事画的概念,中国和西方存在着一定的差异,但在叙事手法、教化功能和图文关系等方面也存在一定的共识。文章在明确叙事画的概念、范畴和功能之后,通过对明清至近现代繁盛起来的杜诗叙事画的文本来源、画家群体及创作原因、选材与形制的关系、艺术手法的演变四个方面进行详细分析,进一步明晰杜诗叙事画的图文关系。杜诗叙事画是对文本来源为杜诗内容的艺术展示,是画家对杜甫叙事诗的接收与传播;同时,观者通过叙事性的图画溯源于杜诗,可以加深对杜诗内容及其反映的唐代社会现实的深刻理解,体味杜甫的圣者仁心,并加深对其图文关系的认知。

We study a four-electron system in a vertically coupled four-layer quantum dot under a magnetic field by the exact diagonalization of the Hamiltonian matrix. We find that discontinuous ground-state energy transitions are induced by an external magnetic field. We find that dot-dot distance and electron-electron interaction strongly affect the low-lying states of the coupled quantum dots. The inter-dot correlation leads to some sequences of possible disappearances of ground state transitions, which are present for uncoupled dots.

In this paper we present a theoretical analysis on the determination of the scaling parameter in the complex-rotated Hamiltonian, which has served as a basis for successful applications of the rigged Hilbert space theory for resonances. Based on the complex energy eigenvalue, E（θ） = ER（θ） - iГ（θ）/2, as a function of the scaling parameter θ, we find that for potential barrier scattering, the condition dГ（θI）/dθ = 0 uniquely determines the scaling parameter 8. The condition d ER （θR）/ dθ = 0 is merely a consequence of the Virial theorem and θI =θR is not a necessary condition for a resonance state. We also provide a harmonic approximation formMism for resonances in scattering over a potential barrier.

The dominant genic male sterility （DGMS） gene CDMs399-3 derived from a spontaneous mutation in the line 79-399-3 of spring cabbage （Brassica oleracea var. capitata L.）, has been successfully applied in hybrid seed production of several cabbage cultivars in China. During the development of dominant male sterility lines in cabbage, the conventional identification of homozygous male-sterile plants （CDMs399-3/CDMs399-3） is a laborious and time-consuming process. For marker-assisted selection （MAS） of the gene CDMs399-3 transferred into key spring cabbage line 397, expressed sequence tag-simple sequence repeats （EST-SSR） and SSR technology were used to identify markers that were linked to CDMs399-3 based on method of bulked segregant analysis （BSA）. By screening a set of 978 EST-SSRs and 395 SSRs, a marker BoE332 linked to the CDMs399-3 at a distance of 3.6 cM in the genetic background of cabbage line 397 were identified. 7 homozygons male-sterile plants in population P1170 with 20 plants were obtained finally via MAS of BoE332. Thus, BoE332 will greatly facilitate the transferring of the gene CDMs399-3 into the key spring cabbage line 397 and improve the application of DGMS in cabbage hybrid breeding.
