Reason analysis as follows: Said from the teaching aspect,because the partial teachers instrumentation experience,teaching item has not demarcated excessively is high,says too mixed,the instrument principle proportion higher has affected the teaching effect;Takes an exam the student thinking mode which the education creates to ossify,student heavy knowledge grasping,light thinking mode training.

原因分析如下：从教学方面来说，由于部分教师本人没有使用仪器的经验，教学目标定的过高，讲得太杂，仪器原理的比重过高等影响了教学的效果；应试教育造成的学生思维方式僵化，学生重知识的掌握，轻思维方式的训练。

This paper brings up with the theory of Virtual Coordinate Measuring System. The basic theoretic models of the virtual coordinate measuring system are given. This theory of virtual coordinate measuring system makes use of the principle of Time-Space correspondence and turns the time pulses into spatial displacement. The virtual coordinate measuring system can take the place of the scale system in traditional instruments, which has the disadvantages of high cost and difficulty ofproduction.

本文同时提出并建立虚拟坐标测量系统理论；该理论从传统的测量仪器出发，将传统仪器的实物标尺系统虚拟化，克服了实物标尺系统加工制造困难，及造价高等缺点，将硬件结构简化；本文提出并建立初步的虚拟坐标测量系统模型，并在三坐标测量机上建立了一维虚拟坐标测量系统的实验模型，初步分析系统的系统误差与其随机误差源。

Following, USB slave driver which was developed on Linux OS was described, which was contacted with USB host driver on windows. So, PC could communicate with instrument.

接着讲述了仪器端的USB设备驱动程序的设计，它作为Windows下的USB主驱动对应的从设备驱动，从而实现了PC机与仪器的通信。

By using Digital-Trailing-Filter and DSP technology, we got solution of trailing filter for transient signal in frequency-scan test,so as to refine the needed test signal from the deformative and weak signal.

通过采用数字跟踪滤波和DSP处理技术，解决了扫频测量中瞬态信号的跟踪滤波，使仪器能够在畸变的、微弱的信号中提取出需要的测试信号，同时使仪器的测量时间大大缩短。

Dr. Pyke contended that the scientific revolution, as we call it, is largely the improvement and invention and use of a series of instruments that expanded the reach of science in innumerable directions.

Dr。 Pyke 坚持认为：科学的改革，正如我们所说的那样，主要是一系列仪器的改善发明以及用途。这些仪器在无数的方向上扩展了科学所能到达的范围。

This paper proposed a new reflection method in micro-friction testing , including its design principles, structure of micro-force sensor, demarcating method of the apparatus.

给出了一种基于光反射法的微摩擦测试仪的设计方法，介绍了该仪器的设计原理、测力传感器的结构设计、仪器的标定方法。

Based on the test of practical measure of laser water-level gauge, the error is less than 0.6mm in the measure range less than 5 meters. Compared with other field water-level measure apparatuses in common use, the precision of laser water-level gauge has obvious improvement. And this gauge can also be applied to physical modeling experiment in river engineering.

4研制开发的激光水位仪经实测检验，在5米测距范围内，测量误差小于0.6mm，比常用的野外水位观测仪器的精度有明显的提高，该仪器亦可用于河工模型试验的水位测量。

Must strengthen the experiment instrument management troop the construction, introduces one batch of technologies perfect, the high quality, the high school record young troop, simultaneously improves administrative personnel's basic quality unceasingly, masters the deep technology base knowledge, can display the precise precious instrument's benefit well.

必须加强实验仪器管理队伍的建设，引进一批技术过硬、高素质、高学历的年轻队伍，同时不断提高管理人员的基本素质，掌握深厚的技术基础知识，才能更好地发挥精密贵重仪器的效益。
