古代汉语课程教学中的异体字问题——互联网时代的古代汉语教学改革探索之一

异体字同假借字、古今字、繁简字,属经典文献中常见的四类用字现象之一,也是古代汉语课程教学中绕不开的内容。从字用角度出发,通过字形结构的分析,分析记词功能相同的异体字之间的异同,这对提升阅读效率,提高古代汉语水平同样有着重要的影响。     

东林学术与王学的斗法——明代中后期东林学派崛起之实

明代中后期,程朱之学受挫于王学之盛,造成了学风空虚的流弊。以顾宪成为首的东林学人源出于王学,而反之于王学,以“格物”辩“无善无恶”,成之于实学,造就了儒学内部王与朱共天下的格局,为东林学派登上历史舞台提供了思想上的准备。     

卫河水对太行隆肛蛙蝌蚪红细胞核异常的影响

运用遗传毒理学的方法,研究环磷酰胺和卫河水对太行隆肛蛙蝌蚪红细胞核异常的影响.结果表明:经10 mg.L-1、20 mg.L-1、40 mg.L-1环磷酰胺溶液和10%、30%、50%体积浓度的卫河水处理4、8、12和16 d,太行隆肛蛙蝌蚪红细胞的微核率和总核异常率明显升高;20 mg.L-1环磷酰胺溶液可作为阳性对照;每一处理浓度下,红细胞微核率、总核异常率均在第12 d达到高峰.说明,太行隆肛蛙蝌蚪红细胞微核和核异常实验对监测污染水体中的遗传毒性物质敏感可行;卫河水污染严重,含有较强的遗传毒性物质,应加快对卫河水的治理,以防止其对地下水源的污染.

浅谈电子政务中的网站建设策略

政府网站是电子政务的主要载体,它形成一站式服务,有效地提升了电子政务的直接性、快捷性、高效性和互动性。本文根据当前政府网站存在的功能不全、更新缓慢、安全隐患等问题,从网络架构、信息安全控制,以及门户网站和内网的建设方面提出的了一些改进意见,使政府网站更加功能化、安全化。     

“无井探测技术”浅论

根据《国务院关于加强地质工作的决定》和中国地质调查局关于加大第二找矿空间深部探测技术研发力度的指示,论述了电磁波测深的理论基础及实施办法。该法可充分应用在区调、普查及先详查深部勘探工作中（亦可应用与建筑基础测量）,尤其是在钻探工区,可预测未知孔的电性结构,从而避免了不必要的打钻,大大节约了盲目钻孔的投资。     

深化"两课"教学改革的原则

"两课"是马克思主义理论课和思想品德课的简称,进入21世纪,"两课"教学在改革中应该坚持以人为本、以平等的身份和学生交流、理论联系实践、"精"和"管用"和多种教学形式相结合的原则。     

The first-principles study on the doping effect of Re in Ni3A1

Using first-principles density function for molecules method (DMol) and discrete variational method (DVM) based on the density functional theory, we studied the doping effect of Re in Ni3Al. The structure relaxation and the alloying energy show that Re has a strong A1 site preference and leads to the local deformation, which is in agreement with the experimental results and other theoretical results. In addition, the charge density difference and the bond order show that Re can strongly enhance the interatomic interaction between the nearest neighbor atoms. From the density of states and the Pauli spectrum, we find that resonance states and localized states are induced by doping Re, and the doped Re atom forms the hybridized bond with the nearest neighbor atoms.     

Relationships of Aegilops tauschii revealed by DNA fingerprints: the evidence for agriculture exchange between China and the West

Genetic diversity and relationships of wild goat grass (Aegilops tauschii Cosson) from Iran and Xinjiang, west China, as well as its weedy type from the Yellow River region of Shaanxi and Henan provinces in China were analyzed by simple sequence repeat (SSR) fingerprinting. A high level of genetic diversity in Aegilops tauschii accessions from Iran was observed, and the richness of genetic diversity was followed by accessions from Shaanxi, Henan, and Xinjiang. The weedy type of Aegilops tauschii showed a close genetic relationship with the wild type from different regions in Iran. The results indicated that the weedy Aegilops tauschii found in the Yellow River region was most likely introduced from Iran—the diversity center of Aegilops tauschii. The weedy Aegilops tauschii populations found in the Yellow River region may be brought into the central part of China as a weed species together with common wheat (Triticum aestivum L.) from the west during various periods of time in history. This finding has provided strong evidence for the introduction of common wheat from the West into China via the Silk Road, and also demonstrated the important role of the Silk Road in the exchange of agriculture and other relevant technologies between China and the West.
