查询词典 keep one's distance from

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。

AbstractAIM: To investigate exophthalmos and interpupillary distance of young females and analyze their relationship with myopia so as to provide a reference standard of interpupillary distance for young females to make suitable spectacles for them.

目的：了解青年女性瞳距、眼球突出度正常值及两者与近视眼关系，并为青年女性眼镜配戴提供瞳距参考值。

By using projective geometry and camera intrinsic parameters and calculating the distance between ship and landmarks, a method of locating ship by measuring the distance based on monocular camera machine vision is presented in this paper.

利用透视投影几何关系和摄像机内部参数，计算船舶与各陆标之间的距离，提出一种基于单目机器视觉的船舶测距定位方法。

The traditional inverse distance weighted interpolation can not satisty the requirment of high accuracy because the atmospheric delay variation depends not only on the distance between the interpolated value and observations, but also on height difference.

针对反距离加权内插法在GPS大气延迟估计加密插值中存在的问题，提出了对样本点和待插值点间水平距离和高程差赋予不同影响因子的改进反距离加权内插法。

The formula group for the design of multi-phase micro Fresnel lens according to scalar diffraction theory was given and the transmission theory of spherical wave were used to deduce the relation of focal distance of the micro lens with spectrum resolution. According to the relation spectrum resolution is inverse proportional to focal distance given a certain incident wavelength and phase number, and the theoretic formula is consistent with reported experimental result.

光谱分辨率是评价衍射微透镜分光特性的主要指标，根据标量衍射理论，给出了多台阶位相型菲涅尔透镜的设计公式，并利用球面波的传输理论推导了微透镜主焦距与光谱分辨率之间的函数关系，得出在入射波长和位相台阶数一定的情况下，光谱分辨率与中心焦距之间呈反比；理论推导的结果与已发表的实验结果一致。

You do this to save money or to make a long distance call if your long distance phone company is kaput.

你这样做是为了省钱或者是你要打长途电话而你的长途电话公司此时正好故障不能使用。

Desmond Keegan's (1988) definition of distance education. Distance education is characterized by

bull；在整个学习过程期间，教师和学生处于准永久性分离状态（以此与常规面授教育相区别

We found 110 Kentish Plover nests in 8 sites, total area 22.74 ha, in Shengshi, Changhua during mid-April to mid-May. The hatching success of 89.09% was high compared to other studies. Thirty-six experimental artificial nests were set for a two weeks period in May to examine the effects of predators and rainfall. Among the 12 unsuccessful nests, 6 were flooded, 4 were abandoned, and 2 were predated. Successful nests and unsuccessful nests showed no difference in distance to nearest road and distance to nearest vegetation line.

调查从四月中旬至五月中旬於样区共追踪110巢东方环颈鴴的孵化情形，并於五月份设置36个人工试验巢进行两星期的追踪以了解捕食和降雨对孵化成功率的影响程度。110巢东方环颈中有98巢成功孵化，孵化成功率高达89.09%，以Mayfield Method 估算之孵化成功率亦高达83.53%，未孵化的12巢中，有6巢是因降雨淹水而失败，4巢是亲鸟弃巢，2巢被捕食。

The new technique reduced the distance ladder to three "rungs":(1) The distance to galaxy NGC4258 is measured using straightforward geometry and Kepler's laws;(2)Cepheids in six more distant galaxies are used to calibrate the luminosity of Type Ia supernovae;(3) The Hubble constant is measured by observing a brighter milepost marker, Type Ia supernovae, in more distant galaxies hundreds of millions of light-years away, embedded in the expanding universe.

这种新技巧简化了距离跳跃为三个"阶梯"：1、星系NGC 4258的距离采用开普勒定律和简单直接的几何方法精确测量；2、在6个更远的星系中的造父变星用来校准Ia超新星的光度；3、深嵌于数亿光年外的膨胀宇宙中的星系中的Ia超新星——一种遥远而明亮的量天尺，被用于精确测定哈勃常数。
