The Japanese dilemmas of modernity: Negative ideology or neopositive ideology?

Japan's postwar economic “miracle” has attracted much attention. The question is whether the miracle arises from the “unique” and enigmatic nature of the Japanese culture. This paper presents Weber's views of modernity and Habermas's reconstruction of Weber's negative view of modernity. Then the paper turns to Habermas's theory of communicative action, especially, his two-level concept of society integrating the lifeworld and system, and his critical theory of modernity, which analyzes and accounts for its sociopathologies. Then the paper proceeds to argue that Japan's modernity was born, not out of disenchantment, but out of reenchantment, with the concimitant consequence in neopositive ideologies through which the system colonized the lifeworld, leading to imprisonment in a “soft” iron cage.

磨加纳米二氧化硅提高铸铁搪瓷耐酸化学稳定性研究

通过磨加方法,将纳米二氧化硅引入到铸铁搪瓷釉中,在不改变铸铁搪瓷釉工艺性能的条件下,提高铸铁搪瓷的耐酸化学稳定性。研究结果表明,磨加一定量纳米二氧化硅到铸铁搪瓷釉中,不仅可以显著提高铸铁搪瓷的耐酸化学稳定性,而且工艺性能也相当优良。     

连铸球铁管模拟试验研究

采用自制的试验机对连铸球铁管进行模拟试验并经初步生产验证。结果表明,连铸球铁管延伸率过低的主要原因是管体内存在以缩松为主的各类缺陷,有效的解决措施是提高铁水的冶金质量,适当的调整化学成份及改进连铸工艺参数,模拟试验试样的延伸率达8—16％。
