Abstract:This paper introduces the operating principle and calibration methods of temperaturesensor's dynamic response characteristics; analyzes the effect factors and errors of the calibration work.

Abstract:介绍了线阵CCD器件用于二线小角度测量的研究，给出了一种线阵（二双坐标自准直仪及其测量原理、仪器硬件和软件设计。实验表明：所研制的CCD双坐标自准在仪量程为±5，分辨力优于0．2"，测量精度优于1"。

Abstract:In computer vision it is very difficult to recognize the six parameters (position andattitude) of a rigid body using single photo. But in the case that some perior knowledge are known,it ispossible for 3D position and attitude parameters recognition. This paper puts forward a method whichdetermines the six parameters and gives the equation of these parameters using three feature points andthe target point. This approach may act well in real-time processing.

Abstract:This paper introduces a method of measuring the projecting amount of the motor enginepiston and the metrological confirmation to the measurement eqllipment on line. The calculating formulaused to estimating the metrological cycle in accordance with the change of the error is also given. Themeasurement of the metrological standard as a product can guarantee the reliability of the measurementequipment in the working cycle.

Abstract:In this paper the design principle, scheme selection and testing method of baluntransformer of Ultra-high Frequency dipole are introduced. The symmetry of the directionality diagramof the Ultra-high Frequency dipole has met the design requirement.

Abstract:This paper introduces the electrical principle of the auto and manual operationprocedures of the electrical control system of the gate-type HBM-3000 Brinell hardness tester. Theproblems occurring for adjusting and maintenance processes and their solving method are describedalso.

Abstract:As a example,the uncertainty evalunation of the lever-type force measuring machinehas been done. The uncertainty evalunation of other force standard equipment can be done by makingreference to this method.

Abstract:This paper introduces a computer system applied to the testment of optical gratings andline standards. This system consists of a personal computer and two 8031 single chip computer.

Abstract:A computer aid system based on contact type interferometer which is a verificationregulation device for Testing gauge block in metric department is introduced. The interfreogram isdetected by CCD and processed by computer instead of estimated by operator. This process is quicklyand automatically and avoid eyestrain. The software was designed according to the last national stand,easy to study and use.

Abstract:In this paper,it is presented that the metrological grantee during ships-warship modeldevelopment must be enforced. In the meantime,it is expounded that in order to rush out the presantdifficut situation of the metrological garantee and supervision during the model development we shouldestablish new idea, straighten out the relationships further and create necessary condition andenvironment favourable for this work to be in progress.

Abstract:The situations of realizing wavelength standard with phase diastimeter and transmittinglength unit size within a large range are introduced. The transmision accuracy is better than that of thegeneral1y used method.
