克尔凯郭尔与卢卡奇马克思主义哲学观的流变

克尔凯郭尔并非卢卡奇偶然提及的学术注脚,而是其理解马克思的背景支援。卢卡奇在不同时期都对克尔凯郭尔作了选择性评述,并将其接受或重构马克思主义哲学的曲折心路历程逐一呈现:通过质疑克尔凯郭尔在人与世界相统一问题上遭遇的“审美—伦理”悖论,青年卢卡奇从心灵掘进到阶级意识,将“主体—总体”辩证图式看作马克思的认识论地平,由此创作出《历史与阶级意识》;之后,为回应该书引起的争议,盛年的卢卡奇以批判克尔凯郭尔的非理性主义为契机,尝试清除“主体—总体”辩证图式中残余的主体形而上学痕迹,开始在方法论维度正视生产实践与经济规律间的有机联系;及至晚年,当卢卡奇立足社会存在,抨击克尔凯郭尔有关主体优先性的宗教幻象时,他又把社会性的“自在—自为”运动内嵌于人性的“主体—总体”辩证图式,并根据超然的悟性,默认马克思主义哲学是将经济规律置于从属地位的劳动本体论,再度退回《历史与阶级意识》的主体形而上学谋划。不难看出,在卢卡奇臧否克尔凯郭尔与马克思的“主体—总体”辩证桥段中,当事人对“人之实然性和应然性的现实统一”问题所秉持的龃龉心态暴露无遗。这也恰好说明,卢卡奇一生都徘徊于正统的马克思主义与人道的马克思主义之间。

This article discusses the influential factors on Al 13 separation considering the interaction of sulfate with various polyaluminum chloride(PACl). The experimental results showed that the basicity( B =[OH]/[Al]), the concentration of PACl and Al/SO 4 ratio exhibited significant roles in the PACl sulfate reaction. It indicated that different species in various PACl underwent different reaction pathway with sulfate. The Al c, colloidal species, formed precipitation quickly with sulfate, while Al b, oligomers and polymers, underwent slow crystallization. And Al a, monomers, reacted with sulfate to form soluble complexes. The kinetic difference of reaction made it possible to realize the separation of Al b and further purification. The decrease of Al a resulted in the limit of ferron method was also mentioned.

The Guanting Reservoir lost its function as the second biggest drinking water source for Beijing due to the pollutions from the upstream flow of Yongding River in 1997 From 1998, lots of studies were carryied out to renew the function of Guanting Reservoir as domestic drinking water source before 2008 Olympic Games. This is the first time that polycyclic aromatic hydrocarbon concentrations in the surface sediment of Guanting Reservoir have been analyzed. A distinctive spatial distribution of PAHs was observed. Sediments from four sites along Inlet of Yongding River to reservoir bam had PAHs concentrations of 1377—2855 μg/g dw in descending order. The composition of PAHs is investigated and used to assess petrogenic, combustion and naturally derived of the sediments samples of Guanting Reservoir. Special PAHs ratios, such as phenanthrene/anthracene(P/A) and fluoranthene/pyrene(Fl/Pyr) were calculated to assess the relative importance of different origins. The data confirmed a relatively high level of petrogenic contamination in four sites. These high PAHs levels were associated with the input of untreated and partially treated industrial sewage. In addition, the concentrations of PAHs compounds of samples indicated that sediments of reservoir were most likely to pose potential biological impairment.
