伸长计

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。

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 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.

设计的双侧电子引伸计，只用两个刀刃而能测得试样的对称双侧变形的平均值，这样便扣除了弯曲变形的影响而得到了纯粹拉伸伸长。

Note that the accuracies of the inclinometers and extensometers are -0.1 mm and -1 mm, respectively.

注意：分别地，倾角罗盘的精确度和伸长计是-0.1 毫米和-1 毫米。

Determine (1)the angle acceleration of the tub wheel,(2) the tensile force of the rope,(3) the reaction forces at point O on the bearing,(4)the friction force between the cylinder and the inclined plane (neglecting the rolling friction).

在图示机构中，沿斜面向上作纯滚动的圆柱体和鼓轮O均为均质物体，各重为P和Q，半径均为R，绳子不可伸长，其质量不计，斜面倾角，如在鼓轮上作用一常力偶矩M。

And unto the angel of the church in Sardis write; These things saith he that hath the seven irits of God, and the seven star I know thy works, that thou hast a name that thou livest, and art dead.

3：1 你要写信给撒狄教会的使者，说，那有神的七灵和七星的，说，我知道你的行为，按名你是活的，其实是死的。
