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。

Aiming at the infrared image of the thermal wake discharged by ships which is difficult to be discriminated,and according to the ideal character of pseudocolor scale advanced by Prof.

文章针对舰船热尾流红外图像难以识别的特点，根据美Pizer教授提出的伪彩色标尺的理想特性，试采用一种连续标尺的优化编码方法解决热图像的细节增强问题，为红外探测潜艇提供比较科学的水面热轨迹情况的依据。

Methods: In control group, the studied model was X-rayed with the central mark of scale penetrated vertically by the centerline of X-ray-tube and both ends of the scale included in the radiation field.

对照组：X线球管中心线对模型1标尺的中点标记进行垂直摄影，照射野包含标尺的两侧标记，摄影距离120cm，物－台距离3.5cm。

On the foundation of further analyzing present situation of our electric transmission price regulation, unifying concrete characteristic of electric transmission enterprises and rod competition theory and achievement rod method,proposed a comprehensive electric transmission price control model which combines price upper limit control and rod competition control,especially a measure model of production efficiency of electric transmission enterprise based on Malmquist index.

3对电力传输企业标竿激励涉及的绩效评价的技术方法、以及标竿激励规制方法和过程进行考察的基础上，进一步分析我国电力传输价格规制现状，结合我国电力传输企业的具体特征以及标尺竞争理论和绩效标竿方法，提出了价格上限规制和标尺竞争规制相结合的综合输电价格规制模型，特别是提出了基于Mulmquist指数的电力传输企业的生产效率的测度模型，并综合输电价格规制模型规制目标、结构设计、输入因素以及+/-Z的X因子以及Z因子的设定进行了深入的研究。

Thin rods like angel hair pasta and vermicelli work best in broths or with thin sauces, while thicker rods like perciatelli go well with heavier, chunkier sauces.

稀薄的标尺象天使头发面团和细面条运转最好在汤里或用稀薄的调味汁，当更加厚实的标尺象perciatelli 匹配很好更重，更加大块的调味汁。

We investigated if differences existed in the length of scale, magnification rate of the model and of the scale, between the mosaicked and single photographic images.

Hawkers fitted a long sight bar for the ring and bead on which the pilot could choose the position of the two elements, some preferring the the ring in the centre with a bead at either end.

Hawker公司把圆环和圆点安装在一个长的标尺上，飞行员可以选择它们在标尺的位置，有些飞行员更喜欢把圆环放在标尺中间，标尺两端各安一个圆点。

Accordingly, undertook improvement to measurement technique and unit of feet lens group, rear sight the design is staff guage of 0.02mm mobile vertical for the least scale division value, telescopic design is collimation binoculars, face of lens of feed rod lever is 1.2362m above to rear sight distance.

因此，对测量方法和尺镜组装置进行了改进，将标尺设计为最小分度值为0.02mm移动铅直标尺，望远镜设计为准直望远镜，光杠杆镜面到标尺距离为1.2362m以上。
