艾米丽·狄金森是美国重要诗人之一,其诗歌已逐渐成为西方经典。西方学者关于狄金森的研究成果为中国的狄金森研究奠定了基础,但由于中西文化和哲学观念的不同,在中国文化背景下的狄金森研究无疑隐含着一种本土意识。用老庄哲学研究狄金森及其诗歌,我们会发现狄诗与庄子散文有某些契合之处。狄诗蕴含着许多与老庄哲学互为相通的道家美学观念,如"崇尚自然"、"无为而无不为"、"法天贵真"、"天地有大美而不言"、"天人合一"等,其中"真"是庄子散文和狄金森诗歌美学的源头。用以"真"为本的美学思想研究狄金森诗歌可被视作是在中国背景下解读狄诗的途径之一,以老庄美学思想研究狄诗更符合中国文化与审美倾向,且有助于从狄诗中发现人类所共有的精神。

Numerical simulation has been performed on the optical transmission enhancement properties of a one-dimensional Ag film single slit structure with grooves. The results show that the position,depth and number of the grooves have great influence on the optical transmission,and surface plasmon polariton and resonance mode are the primary factors. The maximal extinction ratio of 35.8 dB is achieved in the single slit structure by adjusting groove depth.

To better characterize the properties of surface-initiated polymers, simultaneous bulk-and surface-initiated polymerizations are usually carried out by assuming that the properties of the surface-initiated polymers resemble those of the bulk-initiated polymers. Through a Monte Carlo simulation using a heterogeneous stochastic reaction model, it was discovered that the bulk-initiated polymers exhibit a higher molecular weight and a lower dispersity than the corresponding surface-initiated polymers, which indicates that the equivalent assumption is invalid. Furthermore, the molecular weight distributions of the two types of polymers are also different, suggesting different polymerization mechanisms. The results can be simply explained by the heterogeneous distributions of reactants in the system. This study is helpful to better understand surface-initiated polymerization.

The research on the present situation of soil and water development and utilization in shiyang River Basin shows that water resources and eco-environment situation in this area are near the edge of collapse. Since the water crises occurred in the 1970s, problems caused by continuous decrease of water resources have been becoming serious year by year and eco-environment crisis occurred as a consequence. Up to now, 10 380ha of irrigated lands have been abandoned due to sand coverage and water shortage in the basin. Ground water was over exploded in Wuwei and Minqin because of water shortage. Ground water table in many places dropped under 5m （which is the ecology water table level）, thus about 3000ha ofElaeagnus angustifolia forest come to dead and another 5800ha become feeble, and wind-drift sand near the oasis become alive. According to the current situation, if water utilization scope was not enlarged, a water transfer volume of 600×10^6m^3/a from other areas will be suitable to keep water resources and eco-environment safety in the basin, and also 70×10^6m^3/a will be left as spare water. Under this condition the water resources and eco-environment of the basin can reach the critical safety line of 2.032×10^6m^3/a; or if 180×10^6m^3 of water can be transferred from other areas, the water resources can reach the safety warning line of 1.732×10^9m^3/a.
