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。

It was found that the practical value of the relative intensity of ultraviolet radiation in the radiation distance of 50 to 100 cm was conincident with theoretical one calcuIated by the square inverse ratio law. In the radiation distance of 25 cm, the practical value was less than theoretical one.

但实际上治疗用的紫外线灯管多为U型灯管，光照强度与光源距离的关系是否仍符合平方反比定律曾有不同意见，为此我们进行了紫外线照射距离改变对强度影响的测试。

In the radiation distance of 25 cm, the practical value was less than theoretical one. It was suggested that in the radiation distance of 50 to 100 cm, the dosage could be calculated by the square inverse ratio law.

提示：照射距离为50～100cm时可采用平方反比定律计算剂量，如果可能尽量采用相同的距离进行最小红斑量测定与照射或按不同距离时的强度比值折算。

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

These result in the fact that we can hardly discern Cui Wei's painting closely. So appreciators will keep a distance with the artist unconsciously, perhaps this distance is not for the artist to measure.

正因为这样，崔玮的绘画在近距离是分辨不清的，观者在看的同时不自觉地也和艺术家保持了一定距离，或许这样的距离并不是艺术家可以去衡量的。

Keep one's distance 远离;保持远距离 The deer did not trust us and kept their distance.

鹿不相信我们，和我们保持一定的距离。

You can do some assertiveness training.

你可以进行一些自信训练。

We were well on the path to making a rear-wheel-drive global platform," says Mays."

我们正致力于建立一个后轮驱动的平台，"Mays这样说道。"
