查询词典 X-rays

As you know, wavefront systems project parallel rays of light into the eye and measure their displacement when they reflect back out.

光程差OPD 你知道，波前系统投射平行光线进入眼睛，并在这些光线反射回来的时候测量他们的位移。

Focal power tells us .what a lens dose to parallel rays.

焦点光度表示透镜对平行光线所起的作用。

Hence only parallel rays are able to pass through this aperture and therefore as the reflecting object seems to be infinitely remote, there can be no perspective distortion and also magnification is independent of the distance to the lens.

因此，只有平行光线能够通过此孔径，因此，作为反映的对象，似乎是无限遥远，不可能有任何角度的扭曲和放大，也独立于距离镜头。

It was made up of many LED and can replace existing source sometime and can do it more possiblaly.The key of design is how to obtain optical parallel rays from many emanative LED.

经过合理的聚光设计使之符合某些投影设备对亮度要求不是很高，但结构紧凑、性能稳定、使用寿命长的要求。

A minus one diopter lens diverges parallel rays as if they were coming from a focal point at 1 m.

一度的负透镜可以使平行光线发散开来，仿佛这些光线发自于距透镜1 m 远的焦点。

Two convex lenses of equal diameter with a focal length of 3cm and 5 cm respectively have parallel light Rays passing through them.

想象假如没有透镜我们的生活会有什么不同？如下图所示： A 、 B 是两个口径相同的凸透镜，它们的焦距分别是3cm 和5cm。。

Splitting a ray into two parallel rays polarized perpendicularly.

使光波分裂成两束平行的垂直偏振的波。

Close-up performance of the Summicron-M is on the same level as the performance at infinity setting actually infinity is that distance where the incoming light rays are parallel to the optical axis.

近摄表现与无穷远时相当(事实上，无穷远处的光线是平行光轴入射的。对多数镜头而言，大约100倍焦距的物距时，入射光满足这一条件)。

Myopia: As axial length is too long, due to refractive eye refractive power of the system is too strong, resulting in 5 meters away from the formation of the parallel light rays focus before the retina.

近视眼：由于眼轴过长，由于眼球屈光系统的屈光力过强，以致5米以外的平行光线在视网膜之前形成焦点。

The deflection spectra of a beam of parallel rays,as they passed through the field,were figured out according to the deflection program for projection,and the relative projections were acquired from the spectra.

用Gauss函数模拟复杂流场的一个切片，根据偏折层析算法计算该切片的偏折光谱，从偏折光谱中提取投影。

Foods high in this vitamin include oily fish such as salmon, tuna and, and fish liver oils.

维生素D含量高的食物包括诸如大麻哈鱼、金枪鱼和鲭鱼之类的油鱼以及鱼肝油。
