It is the method of special precise vernier caliper height and metrical string length that the same with the machine tooled sensor.

通过随机抽查样件，同时用这两种弯径比测量方法进行检测，发现只有定弓高弦长法，适用于机加工传感器现场几何检定中关键参数弯径比的测量，其结果才是正确可靠的。

Engineers can compare calculation results with the tunnel design curve in order to obtain deviation values of horizontal position, vertical position and angles of the shield machine, and can adopt these results to control tunneling operations of the shield machine.

隧道设计曲线是在城市三维坐标系中设计的，要得到盾构机掘进过程中的误差，就必须通过测量计算得到盾构机在绝对坐标系中的坐标位置和方位角。

Since the late 1960s began to study measuring instruments, has been developed and produced particle size distribution measuring instrument, the testing machine, weighing control, such as white-series.

本公司自60年代末开始研究测量仪器，至今已研制并生产出粒度分布测量仪、探伤机、称重控制、白度仪等多个系列。

Utilized the correlative knowledge of mathematics and theoretical mechanics, the movement measure of the rolling forming of rectangle ring have been studied that based on the ring rolling theory. And the corresponding geometrical models and mathematical models have been established. It was revealed the variation law of ring in the cold rolling process.With the rolling processing, the inside and outside diameters of ring gradually increased with the cures similarly hyperbolic and the augment speed of the inside diameter was obviously larger than the augment speed of the outside diameter. With the rolling processing, the displacement, speed and acceleration of the ring centre gradually increased in the feeding direction in the horizontal and vertical ring rolling mill. With the rolling processing, the moment of inertia which ring reeled its centre and the whirligig of ring gradually increased. It caused the rotary speed gradually decreased. And it was benefit to decrease the circle tolerance and improve the precision of final molding.

本文基于环件轧制理论，运用相关的数学知识和理论力学知识，研究了冷轧过程中矩形截面环件轧制成形的运动测量，并建立相关的几何模型和数学模型，揭示了冷轧过程中环件的变化规律：随着轧制过程的进行，环件的内外径随类似于双曲线的曲线逐渐增大，且环件内径增大速度大于外径增大速度；在卧式轧环机和立式轧环机下，随着轧制过程的进行，环件中心的位移、速度及加速度不断增大；随着轧制过程的进行，环件绕其中心的转动惯量不断增大，导致环件的转速不断减小，这样有利于环件的整圆和最终成形环件的精度。

The aerobics doctrine is based on experiments that measured how exercise affects aerobic fitness, on how much oxygen your body can suck in while you're going all out on a treadmill. It's still true that to attain maximal fitness you have to work out aerobically.

有氧锻炼原则是基于测量锻炼强度影响有氧运动健康的实验，就是测量在你进行跑步机锻炼时你的身体能够吸进多少氧气。

The split between the two groups can hardly be papered over.
