巴赫金对话理论的人文精神

学术交流 2000年第1期 108-114页

本文企图在更为广阔和统一的思想语境里对话性地诠释巴赫金思想的精髓。多样性的巴赫金思想并非散沙一盘,对话理论及其人文精神是它的精髓。巴赫金终生徜徉在哲学、语言学、社会学和诗学各人文学科领域,而其中心工作就是建构自身的对话... 详细信息

本文企图在更为广阔和统一的思想语境里对话性地诠释巴赫金思想的精髓。多样性的巴赫金思想并非散沙一盘,对话理论及其人文精神是它的精髓。巴赫金终生徜徉在哲学、语言学、社会学和诗学各人文学科领域,而其中心工作就是建构自身的对话理论,他以之贯串于所有的人文学科各领域的研究中,而人文精神是巴赫金的对话理论体现出的核心精神,对话理论在其根底上是关于人的理论,是巴赫金终生为人而斗争的理论结晶,闪耀着人文精神的光辉,它以人为对象,关心人的主体建构,关心人的存在和命运,关心人的平等和自由。就诗学来说,巴赫金的杰出之处在于,在20世纪“语言论转向”的文化语境里,他既能以复调小说理论这种对话理论的变体来阐释陀思妥耶夫斯基小说的艺术形式。

Time-resolved fluorescence spectra of europium methylbenzoates (MBA)with 1,10-phenanthroline(phen)have been measured at room *** each of the europium chelates,where the ligand triple states lie above the ~5D_1 level of Eu^(3-),the spectra providc evidence that the Eu^(3-) ~5D_0 state is populated by nonradiative energy transfer from the higher-lying ~5D_1,*** relaxation time for energy decay from ~5D_1 state is measured in the microcrystals to bc of the order of a few *** is suggested that the ligand C=0 and C=C stretching vibrations and Eu-O vibrations,chclate ring and benzene ring vibrations make important contributions to the relaxation *** ~5D\-1—~5D\-0 relaxation time of Eu- (p-MBA)_3phen is shorter than those of Eu(m-MBA)_3phen and Eu(o-MBA)_3phen since nonradiative degradation to ~5D_0 from ~5D_1 appears to be more strongly influenced by the E_u^(3+)sites in the former.

Based on the simulation experiments of water and nitrogen transport, transformation and uptaking, under the condition of different cropping pattern of winter wheat in the greenhouse and the condition of different wastewater irrigation plan. An united computing model of crop growth, distribution of roots, water and nitrogen uptaking by roots and transformation in soil crop system was developed. Growth status of crops, root growth condition and water, nitrogen uptaking pattern by roots under different watering and N pollution conditions were simulated and analyzed due to the development of this mathematical model and the identification of parameters and boundary conditions in the greenhouse, so that it provided a primary computing method for selecting an efficient, productive watering and wastewater irrigating plan.

ABSTRACT: Spectrum analyses of water quality time series have been carried out for five hydrometric stations including Wuhan hydrometric station of the Changjiang( Yangtze) River, etc. The fluctuations of Ca2 +, Mg2+ and HCO3-concentrations in river water under different physical geography conditions have about two-year cycle which is corresponding to hydrometeorological quasi-biannual-oscillation(QBO). Na + Cl- SO2-4 have about two-year cycle in the area lightly affected by human activities while two-year cycle doesn’t exist in the area heavily affected by human activities. All the fluctuations of major ions have about three-month cycle. The river discharge fluctuation accounts for 43. 9% , 45.1%, 54.3%, 33.9%, 30.3% and 42. 7% of the variance of Ca2 +, Mg2+ HC03-, Na+ Cl-, SO2-4, respectively, at Wuhan from 1962 to 1985. According to the spectrum characteristic of major ions, the duration of the time series has to be at least 13 years for trend analysis of monthly water quality data.
