A static expansion vacuum standard apparatus made of metal is described in this paper. The principle of operation and the methods of the parameter determination and synthetic uncertainty analysis are described in detail. Having considered the characteristics of metal structure and the "dynamic "effect", the authors have theoretically induced the calculation formula of standard pressure as follows: PIn=P10+nKP30+YTn, where PIn-the pressure in calibration chamber after n cycles of expansion, Pa; n-the expansion...

A static expansion vacuum standard apparatus made of metal is described in this paper. The principle of operation and the methods of the parameter determination and synthetic uncertainty analysis are described in detail. Having considered the characteristics of metal structure and the "dynamic "effect", the authors have theoretically induced the calculation formula of standard pressure as follows: PIn=P10+nKP30+YTn, where PIn-the pressure in calibration chamber after n cycles of expansion, Pa; n-the expansion steps; P30-the pressure in gas source chamber, Pa; Y-the expansion ratio; P10-the residual pressure inclibration ohamber, Pa;Y-the rate of pressurer ise in calibration chamber, Pa. s-1; Tn-time required for the n-th expansion, s. At the same time, the method of determining the rate of pressure rise was studied experimeexpeimcntaly and a clear conclusion was given. Recently, the apparatus was verified experimentally by the Metrology Science Research Institute of China and showed that its measuring error is not over ±2% in the pres-sure range of 1×10-1 to 1×105 Pa, and it was determined as the first class vacuum standard.

本文介绍一种金属静态膨胀法真空标准装置。文中详细地叙述了该装置的工作原理,参数测定和综合不确定度的分析方法。作者针对金属结构的特点,考虑到装置的“动态效应”,从理论上导出了实用的标准压强计算公式: P_(1n)=P_(10)+nKP_(30)+YT_n,其中: P_(1n)——n次膨胀后校准室的压强,Pa;n——膨胀次数,P_(30)——气源室压强,Pa;K——膨胀系数;P_(10)——校准室本底压强,Pa;Y——校准室升压率,Pa·s~(-1);T_n——膨胀n次所需的时间,S。同时,作者还对装置升压率的测定方法进行了实验研究,得出了明确的结论。最近,本装置经中国计量科学研究院实验认证,在1×lO~(-1) x 10~5Pa压强范围内测量误差不超过士2%,定为一等真空标准。

It is one of the most knotty problems to delimit speedly and accurately the extent and grade of the agricultural lands occupied by the large-scale project, and compensate rationally the natives' loss before the opening of every largeseale project. By using the way of aeronautical remote sensing and image interpretation, we settled the question of classifying compensation about agricultural lands occupied by Jihongtan reservoir in the project of diversion canal from Yellow River to Qingdao city.

It is one of the most knotty problems to delimit speedly and accurately the extent and grade of the agricultural lands occupied by the large-scale project, and compensate rationally the natives' loss before the opening of every largeseale project. By using the way of aeronautical remote sensing and image interpretation, we settled the question of classifying compensation about agricultural lands occupied by Jihongtan reservoir in the project of diversion canal from Yellow River to Qingdao city. This paper expounds the processand the method of selecting the proper image and interpretation criterion, formulating the practicable standard of land's classification, controlling precision in the process of image interpretation and map-making, and verifying the achievement, all of which are very important to similar work in the future. It also provided the scientific criterion for the compensation of agricultural losses and guaranteed the opening of the project on schedule and opens up a new field for applying the remote sensing technique to the largescale projects.
