Further analysis of the contact interface and a more complete theory are needed to extract a reliable spin polarization message with the point contact Andreev reflection method.

利用点接触反射方法获得可靠的自旋极化信息还有赖于接触界面特征的进一步分析。

This paper detail describes the type,production process and some properties of absorber in anechoic chamber.

详细介绍了电波暗室用吸波材料的种类、制造工艺，以及电波暗室用吸波材料的反射率、阻燃性、耐功率等性能指标，为暗室建造企业在选择吸波材料时提供参考。

First, the paper discusses microwave anechoic chamber design techniques before the reflectivity level of quiet zone is calculated.

在对暗室静区反射率电平进行计算以前，本文先讨论了微波暗室的设计，主要可分为以下几个步骤： 1。

Then compares it with measured consequence, observes that they tally well. So, the model of microwave anechoic chamber is right.

所以，用本文提出的模型计算暗室静区反射率电平是正确的，可以投入工程设计使用。

Since I don't have access to an anechoic chamber, I'm performing my tests outdoors on a big field with no nearby large reflective surfaces (usually ~10 m distance is considered adequate for testing frequencies down to 10 Hz).

因为我没有一个完全隔音的视听室，我的测试地点选用户外，在一个没有大面积反射体的空旷的空地上（通常认为左右的距离足够测量10Hz以下的低频）。

Based on the principle of grating diffraction, by using television measuring system to measure the offset between the imaging of incident laser and the optical axis to confirm the angle of incidence and the angle of diffraction of the grating, a method of measuring incident laser wavelength in far field with grating is brought up.

依据光栅衍射原理，采用电荷耦合器件CCD作为探测器，通过测量入射激光成像点在电视靶面坐标系中的脱靶量，确定光栅的入射角和衍射角，提出了一种利用固定式平面反射光栅测量远场未知方位入射激光波长的方法。

Angle of Incidence The angle between an incident ray and the normal to a reflecting or refracting surface.

入射角度入射光与照射在反射或折射平面上的正常光线之间的角度。

Aim To study the effects of walk-off angle on the coefficients of reflection and transmission.

目的 研究离散角对反射与透射系数的影响。

Normal the angle of incident and the angle of reflection

认识光反射的规律，了解法线、入射角和反射角的含义。

Ii Use your diagram to calculate the angle of reflection at the point where the beam of light reflects off the floor.

使用你图解计算光的反射角在在地面的反射的点在哪。

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％。
