Taking into account the large number of information contained in authoritative journal about the History of Science, while avoiding the unreliability of results concluded by a single journal, through analyzing the contents metrically from 1993 to 2005 in three most authoritative journals on History of Science (ISIS, History of Science , British Journal for the History of Science), the paper displayed detailedly the microcosmic orbits of History of Science, revealed the hot points and hold the trends from the macrocosm and provided evidence and theoretical support for Historiography of Science. This will undoubtedly have an important academic value and theoretical significance.This article has three parts.

考虑到权威期刊所蕴涵的大量的科学史信息，同时避免单一期刊研究结论的不可靠性，本文选取国际上最权威的三份科学史综合期刊《爱西斯》、《科学史》、《英国科学史杂志》(British Journal for the History of Science)，对1993-2005年的内容进行计量分析，详细地展示这十多年来科学史研究的微观发展过程，并在三者计量结果进行相互比较印证的基础上，揭示科学史研究热点及发展脉络，从宏观上把握科学史研究的学术走向，对科学史研究重点的调整提供证明与借鉴，并为科学编史学的研究提供理论支持。

It is very important to establish and implement efficient bio-safety management system,and continually improve the system in practice.Thus,the health of laboratory personnel and public can be protected effectively and circumstance pollution due to micro-organism can be avoided.

The innovation of this paper is in order to make a systemic and integrated research of 'hinese milch cow industry, based on the previous research.

本文的主要创新是在综合国内外对于奶牛业研究成果的基础上，力图比较全面、系统地对中国奶牛业粗放式发展过程中各个环节存在的问题进行较为详细的探讨、分析与论证，力图使国内对中国奶牛业的研究达到一个由割裂到完整的状态，为建立一个系统、完整的中国奶牛业研究体系而努力。

The results shows that the two-way lead-lag cointegrating price relationship between milkfish wholesale and retail prices. Since the fish wholesale market could not completely and quickly assimilate the retail market information, the speed of wholesale price response to retail price changes is relatively slow, inducing the low pricing efficiency .

研究结果指出虱目鱼生产批发与消费零售价格间具有显著双向因果价格共整合关系，但生产批发价格因应於消费零售价格变动表现出较弱的价格感应度，其反应消费零售交易资讯比较不易完整且快速地传递到生产批发市场，因而造成生产批发市场相较於消费零售市场呈现较低决价效率。

Using the modified analytical embedded atom method, the physical properties of D03 type Fe3Al alloy, including the lattice constant, formation heat, elastic constants, phonon dispersion curves, density of states, molar heat capacity at constant volume, Debye temperature and thermal expansion, were calculated. The calculated results were compared with the experimental data and those obtained by others.

摘 要：应用改进分析型嵌入原子模型，系统地计算了D03 结构Fe3Al合金的晶格动力学性能，包括晶格常数、形成热、弹性常数、声子谱、态密度、摩尔定容热容、德拜温度和热膨胀系数等，并将计算结果与已有实验数据和其他理论计算结果进行了比较。

SHRIMP technique is applied to the age determination of Shuiquangou alkalic complex. Zircons from monzonite and syenite of the complex in the Dongping and Hougou gold mining district are dated at age of (390± 6) Ma and (386±6) Ma, respectively with U-Pb method. Rock-forming times of the complex is confidently constrained in the Late Caledonian-Early Hercynian period.

采用先进的SHRIMP测年技术对河北水泉沟碱性杂岩体进行了年龄测定，获得东坪金矿区水泉沟岩体二长岩锆石U-Pb年龄为(390±6)Ma，后沟金矿区水泉沟岩体正长岩年龄(386±6)Ma，比较可信地确定了水泉沟岩体的成岩时代为晚加里东期－早海西期。
