测量误差

So we suggest a new method for the measurement of d〓 according to the SHG conversion efficiency at some non-phase-matching direction, the optimum focus parameter ofNPM SHG was given also.

在KTP晶体球中第Ⅰ类PM SHG实验中，我们通过转动晶体球，直接根据谐波输出的强度得到了SHG的相位匹配方向，从而避免了折射率测量或色散方程计算的误差，并得到了精确的KTP晶体完整的第Ⅰ类PM曲线，以及相应PM方向的有效非线性系数d〓，根据这个测量结果，我们对文献报道的六组色散方程进行了比较，认为由Vanherzeele和Bierlein给出的色散方程拟合精度最高。

Especially in high temperature,high pressure and ebullition medium conditons the designed instrument has unique dominance.

在传统液位测量方法可靠性低、误差大的高温、高压、处于沸腾状态工质液位测量场合，具有独特优势。

In revision TKA, we recommend to use lateral epicondyle as the major landmark to restore the joint line from femoral side.

也建议将来要用影像来进行参考点测量时，能够用三维的方式测量避免产生误差。

Experimental results indicate that error analysis in the paper is available and improves measurement precision.

测量结果说明本论文中所作的误差分析是有效的，对提高测量精确度有一定的帮助。

ERROR - the deviation of a measurement from its true value.

误差 －与被测量值的真值相比测量的偏差。

General contact measurement error, the use of non-contact measurement is a better choice.

接触式测量一般误差较大，因此使用非接触式测量是更好的选择。

The error correction of measurement system is very important in the measurement of S-parameter of microwave network used network analyzer.

The paper describes basic working principles of SDH-5 type water-depth measurement instrument. Aiming at the time disagreement between water-depth data and position data,the big error in the reading of water-depth measurment data, low automation,large amount of work in homework data processing, etc.

本文描述了SDH－5型测深仪的基本工作原理，并针对国产SDH系列模拟式水深测量仪器存在水深数据与定位数据记录时间不一致、水深测量数据判读误差大、自动化程度低、内业数据处理工作量大等缺陷，介绍了作者应用单片机技术研制的SDH－5／CLZ－Ⅰ型水深数据采集、处理与串行发送装置。

Based on the concept of antenna near-field measurement and the theory of plane wave spectrum, the theory of plane near-field measurement and error analysis are introduced, two errors of plane radiation near-field measurement are discussed in detail: the probe positioning error and the truncation error of finite scanning.

本文从天线近场测量的基本概念出发，以平面波谱理论为基础，介绍了平面近场测量理论及其误差分析方法。

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。
