In addition,we present the developping and function of Visual Basic and GPS. Especially,this paper take use of the powerful collection exploitation environment of Visual Basic and the ability of double-quick establishing kinds of application, which includes very popular multimedia application and kinds of graph operation.

本文介绍GPS的一些历史和发展前景，GPS的定位系统、组成和单点定为原理，GPS的数据码制、数据帧格式和Visual Basic 的发展、作用、集成开发环境和基础知识，以及完成该程序的关键技术：发展、作用、集成开发环境和基础知识，以及完成该程序的关键技术：VB的串口控件MSComm，最终完成了程序的编写，实现了毕业设计的要求。

An all-optical half adder based on two different cross structures in two-dimensional photonic crystals was proposed. One cross structure contains nonlinear materials and functions as an "AND" logic gate.

提出了基于两种二维光子晶体"十字"逻辑门的全光半加器，其中一种"十字"结构含有非线性介质，起"与"作用，另一"十字"结构不含非线性介质，起"异或"作用。

To study the effect of different types of web cleaner on the card sliver quality,we have done the comparison test between the guide plate web cleaner and the anti-teeth guided flat web cleaner under the condition of the same amount of air volume.

用USTER AFIS单纤维测试系统对上述条件所加工的生条进行了检测，结果显示：反齿导向盖板式棉网清洁器所生产的生条质量总体上要好于导板式棉网清洁器，其原因是反齿导向盖板排除短绒、杂质、棉结等的作用是一种&主动&作用，而导板式棉网清洁器对短绒、杂质、棉结等的排除是一种&被动&作用，梳棉机后罩板处棉网清洁器以采用反齿导向盖板式棉网清洁器为宜。

Should it be a "head office" function, with limited or no local law capacity?

Under the precondition of above analyses, this research compares the meteorite-stricken cases in planets and secondary planets of solar system, the "shielding" and "eroding" effect in aerosphere, the scale of small planets and movement rules, then briefly analyzes the basic reason of mass meteorite-stricken events occurred in earth history.

在上述分析的前提下，本研究从太阳系有关行星和卫星表面陨击现象对比，大气层的"遮蔽"和"侵蚀"作用，小行星的规模及运动规律等方面简要分析了地球历史上大规模陨击事件发生的基本原因。

In this case we are attached to labels, roles,, that affix to our story.

在这种情况下，我们重视的标签，作用，，即追究，以我们的故事。

The simulations show that the air gap is initial at the corner of billet.

过大的结晶器锥度将使坯壳受到结晶器壁的"挤压"作用。

Main purification role is played by artificial medium and aquatic macrophyte in pollutants removal, but the Corbicula fluminea introduced to food chain of combined floating bed enhances the purification effect through the ways as follows: improving the resolvability, ammonification and biodegradability of particulate organic matters, meliorating the substrate supply condition for absorption of plant and degradation of microorganism attached on artificial medium, hastening the growth and activity of microorganism.

污染物的直接净化主体为人工介质和水生植物单元，但在生态浮床中引入河蚬增加水生动物单元，通过食物链的"加环"作用，提高了颗粒性有机物的可溶化和无机化以及可生化性，改善了植物吸收以及人工介质单元生物膜中微生物的基质条件，促进微生物的生长和活性，提高了浮床的净化效果。

The network security is an affected area very widespread question, the topic research content: The network security rank, the data encryption technology, the firewall technology concept, the function, introduced the network security faces main threat as well as question countermeasure, and through the example some company network analysis situs chart from the analysis network security movement environment explained the example plan as well as supplements four safe disposition.
