All dresses that sell in our stores are measured in the flatwise, but due to some of the clothes have flexibility and the way of measurement and margin mark may dissimilar it may cause some slightly different, so that all the size measurement that labelled in our stores are just for reference basis, error margin that within 2cm is consider normal.

本店所有商品尺寸皆平放测量，但因衣服有弹性、测量方式不同标示略有误差，所以本店商品里标注的尺寸仅作为参考基准，误差在2cm以内均属正常范围哟

This paper discusses some application cases of the error propagation law by the examples of trigonometrical survey, and presents that not only sum function and numeral multipling function in which there is only one independent observed value but also more complex functions which are equal in mathematics are not opposite in the process of error propagation according to the error propagation law.

1引言本文以三角测量为例，对误差传播定律一些应用问题进行了讨论，指出当只有一个独立的观测值时，和函数与倍数函数运用误差传播定律不会出现悖论；如果在测量工作中有多余的直接观测值，就需用平差后的间接观测值按协方差传播律来计算，这样数学中相等的函数关系才能得到同样的函

In the mid-field measurement method,space-magnitude error and space-phase error due to the probe position shift are some special errors.

在中场测量中，探头的位置偏移导致的空间误差是其特有的测量方法误差。

Position transformation error is a important part in research of north seeking scheme, the thesis analyses position transformation bringing error of north seeking in two-position scheme and brings forward the method of position transformation error measurement and compensation.

在寻北方案的研究中，转位误差是一个不可忽视的部分，文中以二位置为例分析了转位误差引起的寻北误差和转位误差的关系，并提出了测量和补偿方法。

That is, the output from the coil is proportional to the time derivative of the current and therefore the obtained result is independent of direct current.

针对直流谐波电流测量幅值小、频带宽的特点及误差要求，分析了传感器及测量电路的灵敏度、误差和频率等性能。

A mathematical mode for circle parameters evaluation is e stablished, the corresponding software is designed and has been applied to the m easurement software of universal tools microscope successfully. A practical case for measuring a ring gauge's diameter and roundness error by the image method is given.

建立了圆参数评定的数学模型，设计了相应的误差评定软件，成功地应用到了微机型万能工具显微镜的测量软件上，并给出一个影像法测量光滑环规直径和圆度误差的实例，将改进置换算法的评定结果与其它评定方法进行了比较。

Without measuring the relative angles between objects, the validity of traffic accident on-site sketch is often challenged. In Taiwan, two common measuring methods for drawing a traffic accident on-site sketch: one is trilateration method, and another one is offset method. Both methods have their limits.

现行，常用於绘制交通事故现场图的量测方法有二：一为三定点法，此法常因测线间夹角过大或过小时，使得当测线彼此间的夹角有微小误差时，即造成颇大的位置偏移误差；另一方法为直角坐标法，此法应用在交通事故现场绘制的测量，假设目测标定於基准线与基准线外之测量点的连线成直角，若不为直角时，易造成绘制结果的偏差。

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。
