文化思维模式假说与英语作文教学

本文对1966年Kaplan提出的文化思维模式假说作了进一步论证,指出虽然不同文化有不同的思维模式,思维模式的不同在某种程度上确实决定了段落发展及语篇结构的不同,但英语作文教学的重点更应放在学生对文章的整体性把握以及不同文体之间的区别。

The glass transition temperature and microstructure of polyurethane/epoxy resin interpenetrating polymer networks nanocomposites

GLASS TRANSITION TEMPERATURE (TG) HAS BEEN EXTEN- SIVELY STUDIED FOR MANY POLYMERS SINCE IT IS ONE OF THE MOST FUNDAMENTAL FEATURES RELATIVE DIRECTLY TO POLYMER PROPERTIES. IN GENERAL, INORGANIC NANOFILLERS DO NOT DI- RECTLY CONTRIBUTE TO THE TG OF THE MA…     

Temporal-spatial dynamics of distribution patterns of microorganism relating to biological soil crusts in the Gurbantunggut Desert

Biological soil crusts serve as an important biological factor contributing to the sand fixation. This study was conducted to investigate the temporal-spatial variability of microorganism in crusts relating to locations, soil layers of sand dunes and seasons. At moss-dominated inter-dune areas, higher soil nutrient and water concentrations were likely to maintain the microbial activities. Bacteria showed the highest capabilities of settlement and growth in inter-dunes in both spring and autumn. Soil water content reached the highest value in soil crusts in the inter-dune areas, especially in spring. Variations of quantities of actinomyces and fungi basically showed the consistent trend in different locations of sand dunes. With the deepening of soil layers, vertical distribution of quantities of each microorganism group showed different characteristics because environmental factors fluctuated in both spring and autumn. Among different microorganism groups, bacteria were predominant, actinomyces the next and fungi the least in both spring and autumn in all soil layers （0-20 cm）. The proportion of bacteria and soil water content were higher in spring than those in autumn in all soil layers （0-20 cm）. No consistent trends were found in actinomyces and fungi. The results showed that the quantities of microorganisms were significantly positive correlated with organic matter content, soil water content, total N, total P, available P, available K, pH, electrical conductivity, total salt content,catalase, urease, phosphatase and alkaline phosphatase.     

散射和结构——量子物理学中的要点和相似性

著名物理学家卢瑟福有一句名言：“如果你不能用简单的、非技术的术语解释一个结果，你就没有真正弄懂它”。作者们认为这样一句名言最恰当地表达了他们撰写本书的目的。

纳米技术手册

“纳米材料”是指在纳米尺度（0．1～100nm范围，1nm=10^-9m）上研究物质的特征和相互作用，以及利用纳米尺度的特征开发新产品的一门科学和技术。纳米科技包含纳米材料、纳米器件和对它们的检测与表征等应用性很强的研究和技术领域。通常说的纳米检测和表征是指在纳米尺度上分析纳米结构材料和器件的组成、构造，并且进一步探索新现象，作为发展新的器件和功能材料的手段。     

含周期裂纹的平板弯曲波反射与透射问题的研究

受损伤的固体中含有的微裂纹或微孔洞往往具有周期性,对含周期性缺陷的结构中弹性波分析是力学研究中的重要课题,它直接关系到结构的强度和使用寿命。目前对损伤固体中弹性波散射与透射研究结果主要是弹性动力学平面问题。本文基于弹性动力学理论,分析研究了含有横向周期裂纹的平板中弯曲波的反射与透射问题。给出含有横向周期裂纹的平板中弯曲波的反射波与透射波系数的数值结果。     

山东省学校竞技健美操教练员现状调查与分析

以山东省中学和高校竞技健美操带队训练的教练员为研究对象，对目前学校竞技健美操教练员的现状进行调查分析，得出以下结论：山东省学校竞技健美操教练员队伍学历结构较合理，年龄结构趋于年轻化；教练员执训态度比较积极，动机端正，但专业化较低，专业技能和训练水平有待进一步提高；存在教练员训练方法、手段单一，缺乏创新能力、科研能力较低以及教练员训练水平滞后于运动员的发展要求等亟需解决的问题．
