测量误差

Further, the error of the measurement system is being analyzed,and proposed the method for improving system and monishing error.

此外，对测量系统中的误差进行了分析，提出了改善系统，减小误差的补偿方法。

Usually, we assume that exterior ballisticmeasuring error has normal distribution with zero mean. But during the real measuring,it is possible for exterior ballistic measuring parameters to cause system error.

通常假定外测误差服从零均值正态分布，而在实际测量中，外测参数有可能带有系统误差，它的存在对飞行轨道和落点信息的获取都具有不利的影响。

Strain gauges were introduced to measure the deflection errors of the boring bar, Since they can be facilely installed into the boring bar without effect on its size. The measuring principle of the strain gauge was also studied, it indicated that this indirectly measuring method can perform its function well.

这样的模型不仅能够恰当地描述加工过程的动态变化，而且能在当前状态下预测其未来的变化趋势，从而消除误差补偿与在线测量之间的时间滞后，使误差实时在线补偿得以顺利实现。

The measurement equation of four point method and three point method flat form error separation is given.

列出了四点法－三点法平面误差分离的测量方程，导出了这类方法所对应系统的传递函数G的通式，指出G（0，0）＝0是平面形状误差赖以先行分离的先决条件。

By numerical calculation, the effect on the errors due to image processing, calibration of effective focal length and basic line is discussed.

通过数值计算分析了图像处理误差、有效焦距和基线标定误差对测量方法的影响。

The results of a simulation and an industrial application showed that the proposed method could get accurate results for the system with more than one gross error and was superior to iteration measurement test.

仿真研究与实际应用表明，该组合方法对有多个显著误差的系统也能给出准确的显著误差检测结果，且优于迭代测量检测方法。

Simulation results show that the proposed method comes to stabilization within 50 s and that its tracking initial error can be reduced to the hectometer level with the measurement precision of 20 ns. But the traditional method requires 250 s to go to stabilization and its tracking initial error is greater than the kilometer level.

仿真结果表明，在20 ns的测量精度条件下新方法在50 s内即可进入稳定跟踪状态，跟踪起始误差也减小至百米量级，而传统时差定位方法需要250 s才能进入稳定跟踪状态，跟踪起始误差则超过了千米量级。

Measurements from voltage sources with high internal resistance are subject to a number of errors, such as loading errors from the voltmeter's input resistance and input bias current, as well as from external shunt resistance and capacitance.

对高源内阻电压源的测量容易产生几种误差，诸如：电压表输入电阻和输入偏置电流以及外部分流电阻和电容引起的负载误差。

In this paper,from the view of engineering application,under the condition that three control points formed an isosceles triangle,the relationship is studied between the error of P3P pose estimation methods and the input parameters.

从工程应用的角度出发，在三个控制点构成等腰三角形的条件下，研究P3P位姿测量方法的误差与输入参数误差的关系。

In this case special measures are taken to keep a count of the cumulative DC offset, and to modify the codes if necessary to make the DC offset always tend back to zero.

在这种情况下，必须作特殊的测量来计算直流输出的累积误差，并且在必要时改变电压大小来让误差永远趋向零。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
