高师英语职业技能教育改革

高师院校肩负着培养基础教育师资的重任。衡量师资素质的重要标准之一，是教师职业素质与技能掌握、运用的程度。因而职业技能教育是高师教育中一个重要组成部分。本文通过对高师院校英语职业技能教育的反思，以及对基础教育发展需求分析，提出从可持续发展、教育的内在价值与创新教育的三个层面探讨高师英语职业技能教育改革。

Molecular cloning and expression of interleukin Ibeta (IL-1β) from red seabream (Pagrus major)

The interleukin 1β (IL-1β) cDNA was cloned from the red seabream (Pagrus major) by homology cloning strategy. A cDNA fragment was amplified by PCR using two degenerated primers, which were designed according to the conserved regions of other known IL-1β sequences, and elongated by 3' ends and 5' ends RACE PCR to get the full length coding sequence of red seabream IL-1β (RS IL-1β). The sequence contained 1252 nucleotides that included a 5' untranslated region (UTR) of 84bp, a 3' UTR of 410 bp and an open reading frame (ORF) of 759 nucleotides which could be translated into a putative peptide of 253 amino acids with molecular weight of 28.6 kD and putative isoelectric point pI of 5.29. The deduced peptide contained two potential N-glycosylation sites and an identifiable IL1 family signature, but lacked the signal peptide and the clear ICE cut site, which were common in other nonmammalian IL-1β genes. The RS IL-1β had the highest homology with piscine IL-1β according to phylogenetic tree analysis.     

Development of Full Automatic External Welding Machine for Annular Welds of Pipeline

To meet the demands of rapid development of pipeline constructions in China, a complete set of full automatic external welding machine for annular welds of pipeline and welding procedure have been developed thereof. The system has been applied in the “West-East Pipeline Project” and its performance is proven. With this welding machine the welding parameters can be either preset before or adjusted in real time during the welding process, which avoids the blemishes of same type domestic and international products. Thus it is best propitious to in-situ construction conditions and workers‘ technical level in China. In this article the development of mechanical and control systems of this product is introduced and typical welding procedure parameters are provided.

峰谷电价体制下东北输油管网日输油优化研究

东北原油长输管网是中国规模最大的地区性原油运输系统，就该管网基于峰谷电价体制下的运行现状，建立了线性规划数学模型，提出了日输油计划优化问题，并以铁秦线为例进行分析；初步揭示了峰谷电价体制下日输油计划方式的一些基本规律， 表明在该体制下东北管网具有一定的节能降耗潜力。但该方式在一定程度上受到管道本身运行特性的约束，与热油管道相比它更适合于等温管道。     

Spectroscopic study on the photophysical properties of chlorine substituted tetraphenylporphyrin-histidine and its zinc(Ⅱ)complexes

As the structural analogues of (bacterio)chlorophylls in photosynthetic organisms, porphyrins play an important role in building up artificial photosynthetic systems[13]. In natural photosynthetic pigment-protein complexes,certain amino acid residuals modulate the reactions ofcharge transfer and energy transfer via coordination andother types of interactions with chlorophyll molecules.For instance, in higher-plant photosynthetic reaction cen-ter PSⅡ, the oxidization-reduction system consistin…     

海洋光学遥感技术的发展和前沿

空间遥感与信息技术已经发展成为满足人类对海洋资源和环境不同尺度和不同层次连续、动态的信息需求的必要手段。海洋光学遥感在实施大范围海面瞬间信息监测、数年至几十年长序列全球海洋数据采集等方面，发挥了常规调查方法所不能替代的优势。从20世纪70年代开始，国际上发展了利用测量离水辐射率的原理，用现代的卫星遥感技术来实时监测海洋水色环境。80年代以来，我国对该项高技术也十分重视，并有了长足进展。文章回顾我国近20年来海洋光学遥感技术的发展；讨论了当前国家在海洋权益、防灾减灾、海洋资源管理和开发等方面的进一步需求；论述了该技术在环境监测应用导向下的前沿，如：高精度分析和定量化、高频率长序列监测和业务化趋向、多平台监测数据同化和核心技术合成。
