To notice the problem must treat three important contestation points:the literature inheritance,relations of politics and literature and Realism.Concerning this it is thus clear that the evolution of research methods and academic words,this provide to the angle of view,for the combine of Marxist of Chinese ancient literature theory and Naturalization of Marxist Literature...

在探讨这一问题时，要注意对待文学遗产、政治与文学关系、关于现实主义三个论争要点，从中可见研究方法与学术话语的演进，这就为中国古代文学思想马克思主义化和马克思主义文艺理论中国化相结合，并建立有中国特色的当代文学学体系提供了研究视角。

PDGF-BB is the most effective subtype in the PDGF family on the metabolism of osseous tissue or the treatment of wound healing, and its clinical application was approved firstly among the growth factors although it was used to treat the decubital ulcer of diabetes.

本研究通过分子克隆方法获取人血小板衍生生长因子B链成熟肽基因，构建原核表达载体；利用大肠杆菌体系原核表达人血小板衍生生长因子B链前体蛋白，并纯化、复性进而获得具有功能活性的PDGF-BB；并对获得的重组rhPDGF-BB蛋白进行体外功能活性鉴定，同时，初步探讨PDGF-BB在毕赤酵母中的表达，为寻找更优化的表达纯化方法提供实验学依据。

Based on the studied materials of oil fields and outcrops in the northwestern area of China, selecting the most important oil-bearing rservoirs (fiuvial and deltaic sand bodies) in terrestrial facies lacustrine basin, utilizing the theory and method of sedimentology, this paper explores the key problems, which are the studies of depositional model, heterogeneous model and predictable model, in order to present conductive information for the application of corresponding area and similar reservoirs, simultaneously, to deeply promote the organic combination of theory and practise.

本文根据在我国西部地区油田及露头区研究的资料，选取陆相湖盆沉积体系中重要的油气储层类型—河流和三角洲沉积砂体，以沉积学的原理和方法为基础，对油藏研究中的沉积模型、非均质模型和预测模型等热门研究课题进行研究，以指导相关地区类似油藏或储层的精细描述，从而达到使理论研究和生产实践进一步有机地结合。

The chemistry behavior research of wollastonite indicated that the silicon-potassium fertilizer has a chemical active in organic acid.The factors affecting manurial effect of silicon-potassium fertilizer are not only soil pH and desilicification,but also content and type of organ in the soil.Wollastonite chemistry behavior indicates that silicic acid can be dissolved out from silicon-potassium fertilizer in chlorhydric acid solution if pH of solution is not smaller than 2. The drop of apparent density,increase of DBP sorptive rate and specific surface for leavings indicate that hydrated silicon oxide is polyporous,and those mineralogic feature presignify that silicon-potassium fertilizer has a role of conservation of both Moisture and Fertility and improving soil structure.After active ingredient releasing,silicon-potassium fertilizer leaves half the substance (non-active ingredient)in soil.

熟料单矿物在酸溶液中的化学行为研究表明，硅钾肥矿物在有机弱酸中的化学活性较好，影响硅钾肥肥效发挥的因素是土壤pH值和土壤的去硅化程度，还有土壤有机质的含量与种类；硅灰石在盐酸溶液中化学行为表明，在反应体系pH不小于2的情况下，硅钾肥矿物大量溶出硅酸根组分；溶解残余物表观密度降低、DBP吸着率和比表面积增加表明水合二氧化硅是以多孔形式存在，为硅钾肥具有保水保肥、改良土壤结构的提供了矿物学依据。
