Aim To determine the measured profile of a wheel in railway vehicle. Methods So-called piecewise curve-fitting method of the third derivative continuity is employed.

The method of adjusting the pose of measured profile with theoretical profile, according to different kinds of parts, integrated feature points or ellipse of inertia for realizing pre-position should be used. 3.

研究了被测轮廓与理论轮廓位姿调整方法，针对不同零件分别采用综合特征点或惯量椭圆实现预定位。

ICT can clearly, directly and accurately show us the structure, density change, character of a absence, position and size of measured profile by computer image.

工业CT能以计算机图象的形式，清晰、直观、准确地呈现被测物体断面内部的结构、密度变化以及缺陷的性质、位置及大小。

Using the model the air-sea fluxes of momentum, sensible heat and vapour can be calculated from measured profile data.

依此模式，可由实测风温湿廓线数据计算海－气动量、感热和水汽通量。

In this article, the measured profile is expressed by three cubed spline function, a precise mathematical model of evaluation is built and an approaching method for evaluating the profile error of the random plane curve is proposed.

采用三次样条函数拟合出被测物体的轮廓曲线，并建立了评定线轮廓度误差的精确数学模型，提出一种用逐次逼近思想来评定平面自由曲线的轮廓度误差的方法。

The approaching method is one kind of method which can conform to the least zone principle best. While obtains the shape error, the position error between measured profile and its theory profile can obtained.

该方法是一种符合最小区域原则的轮廓度误差评定方法，并且在得到形状误差的同时，可以得到被测轮廓与理论轮廓之间的位置误差。

The resulting offset voltage is subsequently subtracted from the measured signal to maximize measurement accuracy.

随后从被测的信号中减去测量出的偏置电压,以便最大限度地提高测量的准确度.

The computation shows that the result of this coupling model fits the measured value very well.

计算结果表明,耦合模型计算结果与实测值拟合很好.

For the measured value of the Hubble constant, this distance is about 14 billion light-years .

由量测到的哈伯常数值来推断, 这个距离大约是140亿 光年 远.

Verified by using the experiment data, the result shows are adjacent to the measured value.

实测资料验证表明,计算值与实测值符合较好.

Parameter characterizes the dispersancy assigned to the measured value reasonably and related to the measuring result.

表征合理地赋予被测量之值的分散性,与测量结果相联系的参数.

For absolute measurement , the measured value is held even as power is cut off.

绝对测量时,即使电源切断, 该测量值仍能保持.

As a result, a measured value using this method is not reliable.

因此采用这种方法测得的数值是不可靠的.

The measured value and calculated with model show that conformity exceeds 70 %.
