萨义德后殖民的文艺学方法论意义

萨义德的后殖民理论揭示文化霸权,反对二元对立的思维方式,提倡在阅读文学文本时采用的“对位式阅读”对文艺理论与文学比较具有很好的方法论意义。只有以交叠区域视点来展开交往与对话,平等理性跨文化的交流与研究才有可能。     

A study revealing the key aroma compounds of steamed bread made by Chinese traditional sourdough

Aroma of Chinese steamed bread (CSB) is one of the important parameters that determines the overall quality attributes and consumer acceptance. However, the aroma profile of CSB still remains poorly understood, mainly because of relying on only a single method for aroma extraction in previous studies. Therefore, the objective of this study was to determine the volatile aroma compounds of five different samples of CSB using three different aroma extraction methods, namely solid-phase microextraction (SPME), simultaneous distillation-extraction (SDE), and purge and trap (P&T). All samples showed a unique aroma profile, which could be attributed to their unique microbial consortia. (E)-2-Nonenal and (E,E)-2,4-decadienal were the most prevalent aromatic compounds revealed by SDE, which have not been reported previously, while ethanol and acetic acid proved to be the most dominant compounds by both SPME and P&T. Our approach of combining three different aroma extraction methods provided better insights into the aroma profile of CSB, which had remained largely unknown in previous studies.     

磁性Fe3O4微粒表面有机改性及表征

利用化学共沉淀法制备了磁性Fe3O4纳米微粒,用硅烷偶联剂MPS对所制备的磁性微粒进行表面有机改性,并用FTIR、XRD、TEM、XPS等表征方法对样品进行了表征,结果表明:MPS已经很好地键连到了磁性Fe3O4纳米微粒的表面。改性的磁性Fe3O4纳米微粒具有亲水和亲油两种性质,采用改性后的磁性微粒可以显著改善磁性微球的性能指标。

我国钢铁行业上市公司资本结构与企业业绩关系实证研究

借鉴国内外相关研究成果,选取净资产收益率作为企业业绩指标,选取资产负债率和长期负债率作为资本结构指标,分别建立一次回归模型和二次回归模型,并采用我国钢铁行业上市公司数据进行实证研究。一次回归结果表明,我国钢铁行业上市公司资本结构与其业绩成负相关关系;二次回归拟合效果更好,表明我国钢铁行业上市公司资本结构与其业绩成倒U型关系,并存在最优资产负债率(值为0.3738),使得业绩指标达到最大值。由于我国钢铁行业总体资产负债水平较高,在二次曲线的右边,右侧区间表现出负相关关系,也验证了一次回归呈负相关。应积极发展债券市场,大力完善破产制度,以此来优化我国钢铁行业上市公司的资本结构进而提高其业绩。     

Effect of cultivating conditions on α-galactosidase production by a novel Aspergillus foetidus ZU-G1 strain in solid-state fermentation

The work is intended to achieve optimum culture conditions of α-galactosidase production by a mutant strain Aspergillusfoetidus ZU-G1 in solid-state fermentation (SSF). Certain fermentation parameters involving moisture content, incubation temperature, cultivation period of seed, inoculum volume, initial pH value, layers of pledget, load size of medium and period of cultivation were investigated separately. The optimal cultivating conditions of α-galactosidase production in SSF were 60%initial moisture of medium, 28 ℃ incubation temperature, 18 h cultivation period of seed, 10% inoculum volume, 5.0～6.0 initial pH of medium, 6 layers of pledget and 10 g dry matter loadage. Under the optimized cultivation conditions, the maximum α-galactosidase production was 2037.51 U/g dry matter near the 144th hour of fermentation.
