To realize the management of the flexible subject categories and the database system, an cross-platform information management software has been developed, which also explored an intelligent functional module to fetch and analyze web information automatically.

本文在Linux系统下，编制了专题信息系统平台和管理工具：采用Web数据库技术，构建了后台的数据库系统；建立了前端网站系统(http：//159.226.63.156/metalnanol/)，包括专题信息库和各种检索功能与用户交流功能；建立了跨平台的信息管理工具，实现了灵活的专题信息分类管理、网络信息的自动获取与分析功能以及数据库各项管理功能。

At first, this paper gives the brief introduction of the history and present status of accelerometer and its testing technology, the working principium and math model of the liquid floated pendu-lous accelerometer, and then, decides the binary width pulse force retrim loop as the design proposal of testing system, researches the transfer function of every part in the system emphasizly, analyses the stability of the whole accelerometer testing system from the angle of control theoretics by the open loop transfer function of system, and designed the correcting net, analyses the basal problems such as resolution, sampling restraint, precision and so on, designs the hardware testing circuits such as preamplification, band-pass filter, alternating amplifier, phase sensitive demodulatorn, pulse-width modulation, frequency scale circuit, moment current generator. Finally, using the graphics program language LabV-IEW which is designed for testing field especially by NI accomplishes the solfware design of testing system,realized the testing functions.

首先对加速度计及其测试技术的发展历史和现状，液浮摆式加速度计的工作原理和数学模型等作了简要的介绍，然后确定了以二元调宽脉冲再平衡测试回路为设计方案，并从控制理论的角度进行了分析，着重研究了系统中各部分的传递函数，利用系统开环传递函数分析了系统的稳定性，同时设计了系统的校正网络；分析了二元调宽脉冲再平衡测试回路的分辨率、采样约束以及测试精度等基本问题，并按照系统分析的结果设计了包括前置放大、带通滤波、交流放大、相敏解调、脉宽调制、频标电路以及力矩电流发生器等测试系统各部分硬件电路，验证了电路的正确性，最后按照测试系统的要求，采用了美国NI公司专为测试领域所开发的虚拟仪器工具——LabVIEW作为测试软件开发工具，利用该图形化编程语言完成了测试系统软件部分的设计，实现了测试功能。

Therefore explring the difference betweens science language and daily language , understanding the influence of language skill on science study is of great significance to promote students'language and science literacy.

语言是交流和思维的工具，新课程背景下强调学生的自主学习、合作学习和探究学习，强调学生与教师、学生与学生的交流，这对学生的语言技能提出了新要求，探讨科学语言与日常语言的不同，弄清语言技能对科学学习的影响，对促进学生语言技能与科学素养的共同发展具有现实意义。

The new curriculum requirs autonomous learning, collaborative learning and inquiry learning. It also advocates the communication between students and teachers and students themselves, which sets new demands on students'language skills. Therefore explring the difference betweens science language and daily language , understanding the influence of language skill on science study is of great significance to promote students'language and science literacy.
