反射

The influence of surface reflection to total absorbing performance is discussed and the corresponding theoretical formula are presented under the condition of generational matching law when electromagnetic wave irradiates on the coating absorbing material which takes metal as the base.

利用三维网格法讨论了电磁波垂直入射的情况，结果表明：涂层吸波材料的介电常数ε对表面反射的影响起主要作用，而磁导率μ的作用并不明显，即在考虑表面反射的优化设计中调节ε是主要的。

When Chinese traditional landscapes turn to modern products of technical material, when stainless steel mirrors the surrounding environment, and when the reflected images develop to be misshaped and broken, you can feel the clue of tradition has lost its visibility, like the vague, dream-like past memories of one's life.

传统趣味的山水景物，也因此被置换成不合时宜的现代化材料制品。抛光后的不锈钢能够反射周围环境的影像，并使反射在上面的任何事物都变得扭曲和破碎。于是，那些已经斑驳的传统文脉就成了模糊不清的旧梦和往事。

In land areas with highvelocity rock outcrops,the seismic data recorded by vertical geophone deviate from the data of reflected compression wave with the increment of dip angle of strata and incident angle of reflection wave,which results in the difficulties of conventional seismic exploration in the near-surface high-velocity rock outcropped areas.

结果表明，当近地表速度为低速时，可以将垂直检波器记录的地震记录近似等同于反射纵波记录，这就是常规地震勘探在低速带区勘探取得成功的原因之一；当近地表速度为高速时，随着界面倾角和入射角的增加，垂直检波器记录的地震记录等效为反射纵波记录的误差增大，这就是存在高速近地表区地震勘探的难点之一。

The atmosphere splits or "refracts" the star's light, just as a prism splits sunlight.

大气层将星星们发出的光进行了反射和折射，就像棱镜反射太阳光一样。

The big velocity difference between salt domes and surrounding rocks leads to poor reflection and distortion of salt bodies and substrata.

由于盐丘和围岩间存在巨大的速度差异，因此导致盐体本身和下伏地层在常规地震资料中出现反射品质降低、构造失真、畸变（如盐下石炭系目的层地震反射层在盐丘部位出现构造上拉现象），消除盐层的影响是含盐油气盆地勘探的重要课题。

If I bounce my flash by tilting and swiveling it, I get to bounce the light at an angle - away from the subject.

当需要倾斜和旋转闪光灯进行反射闪光的时候，我习惯于在闪灯和被摄主体间形成一定的角度，这样反射回来的光线就具有一定的方向性，从而形成一定的光影效果。

For Hilly area, in order to compress the topographic effect, the simple ratio of band and simulated reflectance techniques were used, the ratio band and Simulated reflectance band which combined with original bands, were use to vegetation classification, what's more, Tasseled cap processing was used.

低山丘陵地区的植被分类，我们采用简单比值处理和模拟地表反射技术来抑制地形遮阴的影响。把经比值处理的波段和经模拟反射处理的波段，与原始TM波段进行组合，并用于对山区的植被进行分类，分类结果如下

Second, skin coating on the surface of the body, the body is the main organ of one of its most extensive distribution network of capillaries, lymphatic and rich network of nerve endings, net meridian venae, over the hundreds of millions of physics and chemistry Receptor reflex and more than 800 key acupuncture points and dozens of visceral reflex zones, with breathing, excretion, absorption and neuroendocrine function such as bidirectional regulation.

二、皮肤被覆于人体表面，是人体主要的器官之一，其内分布有最为广泛的毛细血管网、淋巴网和丰富的神经末梢系统、经络络脉网，还密布着数以亿计的理化反射感受器和八百多个重要穴位及几十个内脏反射区，具有呼吸、排泄、吸收及神经内分泌双向调节等重要功能。

METHODS The electronystagmogram,posturogram and related parameters of40normal subjects and82patients suffering from vertigoes were measured with electronys-tagmographyand posturography.

目的 测定与分析眩晕患者的前庭眼反射与前庭脊髓反射功能。方法用眼震电图描记法和姿势描记法测定40例健康者和82例眩晕患者的眼震电图和姿势描记图及有关参数。

A multi-distance measurements method is employed in this paper. A single parameter fitting method and a double parameters (reduced scattering coefficient and amplitude factor) fitting method on the basis of the least square Newton fitting algorithm is used to derive the optical parameters respectively. For the finite-thickness homogenous tissue, it can be concluded that the rest terms in expressions of diffusion reflectance and transmittance for the corresponding tissue geometries that subtract the exponential term contained source-detector distance depend on the detected position weakly.

在多程测量的基础上，使用单参数最小二乘牛顿法拟合方法和双参数（约化散射系数、幅度因子）最小二乘牛顿法拟合方法，得到有限厚均匀组织的反射率分布和透射率分布公式中除去包含测量位置的指数项的其它部分对测量位置皆具有弱依赖性的结论，并对拟合结果进行了分析讨论；而对于有限厚平板状双层组织，可根据对反射测量结果及透射测量结果进行拟合所得的约化散射系数间的差异及常数因子的正负判断双层组织的可能结构分布。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
