As MEMS (Micro Electro-Mechanical Systems) technology progresses rapidly, the synergism between MEMS and biomedical technology becomes closer than ever before. When the uTAS was introduced in the last two decades, many microfluidic chips, microelectrodes, and microreactors are being studied for drug detection, environment detection, gene analysis etc. Due to its small volume, low pollution, low consumable and good portability, uTAS plays a very important role in biomedical, biochemical, environment engineering fields.

随着MEMS(Micro Electro-Mechanical System，微机电系统)制造技术的不断发展，生物医学与其之间的联系越来越紧密，自上世纪90年代初提出uTAS(Micro Total Analysis System，微全分析系统)之后，各种各样的微流控芯片、微反应器、微电极、微分离器等便大量涌现，广泛应用于药物检测、环境监测、基因分析等诸多领域中，并且由于其试剂消耗量少、检测效率高、环境污染小、体积小、易于携带等优点，在生物医学、化学、环境工程等领域受到越来越多的重视。

Respective to American courses, they fall into two parts: the courses required to graduate from Wasatch are: Math, Physics, Chemistry, Biology and English, and courses which are required to get into top universities, such as AP exams.

美方课程分两部分：一是满足瓦萨奇高中毕业要求的课程，如数学、物理、化学、生物、英语等；二是满足学生到美国读一流大学需要的课程，即AP课程。

It coalesces the knowledge and technologies of traditional engineering, such as electricity/electronics, mechanical, civil, chemical, aeronautic/aerospace, nuclear, biomedical and material, with that of computer science, mathematics, physics and even social science.

它将传统工程领域的知识和技术，比如电子、机械、土木、化学、航天、核工业、生物医学和材料科学等，与计算机科学、数学、物理和社会科学这些领域中的知识和技术融合在一起。

From the analysis of the magnetic susceptibility,TOC,TN,pigment,organic car-bon isotope ,HI,saturated hydrocarbon and 14C dating etc. of the sediment samples from coresof two boreholes in the Taihu lake,a knowledge of the evolution of paleoenvironment of thelake during the last 14ka is achieved. The results show that the lake has undergone the fol-lowing stages .. The Lake was at a low level ,or even became exposed during 14.3-13.3kaBP,reflecting an arid climate. There existed a transitional stage during 13.3-12.4kaBP,the climate being slightly warm and wet. There are indications of a cold and dry climate around 11.5kaBP,probably corresponding to the Younger Drays event ,comparable with other areas in east China.

本文根据东西太湖短柱岩芯的沉积物的物理、化学、生物指标的综合分析，讨论了该区距今14ka来的古气候变化过程，结果表明14.3-13.3kaBP，太湖水位低，环境指标甚至表现为暴露特征，反映了气候干旱：13.3-12.4kaBP，为偏暖湿的过渡阶段；该孔柱270-280cm(11.5kaBP左右)各类指标均明显更映冷干特征，可能是Younger Drays事件的记录，与我国东部其它地区有可比性；约10.9-10kaBP，这一时期是整个研究时段内一个较显著的温暖期。

The system of nano-structured assembly and molecular assembly is a new field, which is originated from intercrossing and derivatives of physics, chemistry, biology and material science in nanometer scale. It has not only brought the new opportunity to synthesis of new materials, but also opened the new dimension for physical and chemical investigation. The most importance is that it will be the basis of nano-structured device in the future.

纳米结构的组装和分子组装体系是物理、化学、生物学、材料科学在纳米尺度交叉而衍生出来的新的学科领域，它为新材料的合成带来新的机遇，也为物理和化学的研究提供了新的方向，更为重要的是它将成为下一代纳米结构器件的基础。

The existence of natural toxins is a fundamental phenomenon of life, it is a set of specific bioactive chemical substance, which evolved through a long period from nature. Natural toxins show multiplicities in biogenic source, chemical structure, biological function and active mechanism.

生物毒素的存在是一种重要的生命现象，它是自然生物界长期进化发展的具有特殊生物活性的化学产物，而且在生源、化学、功能、作用机制等方面表现出多重多样性。
