查询词典 extensometer

In a routine test, these points are marked by center punch, but, if a more detailed test is to be carried out, the extension is measured by an instrument called an extensometer, which produces the gauge points when it is attached to the test-piece.

在常规测试中，这些点用中心穿孔机标记但是，如果要进行更仔细的测试，延伸量要用名叫引伸计这种仪器进行测量，当引伸计连接试样时，它产生标距点。

The weight of the extensometer is balanced by means of a counterweight.

利用一个配重来平衡引伸仪的自重。

The anchored points of each extensometer were located at depths of 8, 12, 16, 20, 24 and 30 m below the ground surface.

每个伸长计的被固定的点在土地的表面下面位于 8，12，16，20， 24 而且 30 m 的深度。

Besides, an anchored multiple-point extensometer was designed to ensure accurate monitoring according to the engineering conditions.

这也是隧道工程监测技术的积极探索。

The operating principle and the key manufacture technique of pre-stressed sensors and vibrating string extensometer have been approached.

SATEC Series 300 LX , featuring an Automatic Extensometer and Pneumatic Grips, and 3300 series testers.

SATEC 系列300 LX 兼有自动伸长计和气动握紧，及3300系列试验器的特点。

The results of measurement of such electronic extensometer are instable and then more errors may be included. The first writer of this paper designs the two-side electronic extensometer, which also has two edges but it can be fastened on two symmetric sides of the tensile specimen.

最近四十年发展起来的各种电子引伸计在讯号放大及数据采集和处理方面有非常突出的优点，但大多数电子引伸计如单侧电子引伸计(图1)、光栅引伸计和视频引伸计都是测量拉伸试样单侧的变形[3]，笔者称它们为单侧电子引伸计。

The one-side electronic extensometer fastened on only one side of tensile specimen cannot eliminate the effect of bend of eccentric tension. The results of measurement of such electronic extensometer are instable and then more errors may be included.

目前，国内外使用的电子引伸计多数是测量拉伸试样单侧的变形，由于拉伸试样往往发生偏心拉伸，单侧测量的引伸计无法扣除偏心拉伸的影响，因而其测量结果极不稳定和产生比较大的误差。
