There is nonlinearity between the distance of the object and the distance of its image in the laser triangulation.

由于激光三角法具有原理上的非线性，为了便于测量和控制，需要进行补偿。

This image has travelled a great distance, and because the intensity of light falls off as the square of the distance, the loss of light is great .

这种图象已移动了很长一段距离，并且由于光的强度随距离的平方而减弱，所以光的损耗是非常大的。

That is, the objective distance can be changed freely while keeping the image distance constant and vice versa.

并给出了多层光子晶体平板的成像结果，实现了正方形三角形混合晶格光子晶体平板近远场成像。

A line considered a limit to a curve in the sense that the perpendicular distance from a moving point on the curve to the line approaches zero as the point moves an infinite distance from the origin.

渐近线与曲线极限相关的一条直线，当曲线上某动点沿该曲线的一个分支移向无穷远时，动点到该直线的垂直距离趋于零

The difficulty lies in the fact that it is hard to find a signature model that is insusceptible to intro-classes distance and at the same time is sensitive to inter-classes distance.

摘要离线中文签名的自动验证是一个极其复杂的问题，其困难主要在于难以建立能够容忍类内偏移同时对类间区别相对敏感的签名模型。

Near vision habits that influenced the onset of low vision included reading distance, distance of television, interclass activities, reading more than an...

结论看书距离和看电视距离越远是视力低下的保护因素，课间活动少、连续看书1小时以上是视力低下的危险因素。

Based on the principle of Otsu method with maximum variance between threshold algorithm of image segmentation, an improved method derived from Otsu algorithm is put forward, which combines interclass distance with intraclass distance, a partial recursive algorithm is used to search optimum threshold.

基于最大类间方差阈值图像分割算法的基本原理，然后结合目标与背景两类之间间距和类内距离对图像分割效果的影响，提出了一种改进的最大类间方差法，运用递归思想局部搜索图像的最佳阈值。

Followed by the decomposition phase is optimal feature subset selection, in which the optimal feature subset acquired the best divergence is obtained according to interclass/intraclass distance of the training samples. This procedure is implemented by a Genetic Algorithm, with each possible feature subset encoded as chromosome. Fitness scores in GA are calculated and evaluated based on Jeffries-Matusita distance of the selected training samples.

然后，对这些线性光谱特征利用遗传算法结合训练样本计算类内/类间距离搜索最优分类子集，其具体染色体编码取可能的特征号，适应度函数基于样本平均Jeffries-Matusita距离计算。

The radiographs were transferred into a computer and calibrated and measured with the image J software. The following factors were measured : [1] the distance from the base of the contact point to the bone crest. [2] The length of the interproximal dental papilla. [3] The width of keratinized gingiva. [4] The interdental distance.

使用测量软体计算距离，并评估下列各项影响齿间乳突存在与否的因子，包括：[1]牙齿接触点到齿槽骨嵴的距离；[2]齿间乳突的长度；[3]齿间角化牙龈的宽度；[4]牙齿间距。

Meanwhile, we explored discharge characteristics and influence factors (interelectrode distance, temperature, atmospheric pressure, relative humidity, etc) through experiments. To optimize the characteristics of ionization sensor, we studied the diameter, distance and height of carbon nanotubes when field effects of carbon nanotubes were in optimized conditions.

出于优化电场效应、增强纳米碳管气敏传感器气敏性的需要，本文实验研究了纳米碳管直径、间距和高度的可控制备方法，最终传感器采用了符合电场效应优化条件的纳米碳管材料。
