查询词典 reflected ray

With the dimensions of the prism as shown, the angle of incidence of the ray with parallel polarization exceeds the critical angle and this ray is therefore internally reflected and deflected from its original direction.

Alternatively, the spectral softening above 2 GeV could be due to gamma-ray absorption via photon-photon pair production on the soft X-ray photon field of the host active galactic nucleus, but such an interpretation would require the dissipation region to be located very close (l~100 gravitational radii) to the black hole, which would be inconsistent with the X-ray spectrum of the source.

另外的关于2 GeV以上能谱变软的可能解释是高能光子和寄主活动星系核的软X射线辐射场通过电子对产生反应而被吸收，但是这个解释要求反应区域要很靠近中心黑洞(1~100倍引力半径)，这和3C 454.3的X射线测量谱相矛盾。

X-ray diffraction is one of the most common and efficient ways to measure a superlattice structure. This dissertation displays the detail results for characterization of Ge〓Si〓/Si superlattices by x-ray diffraction (including x-ray small angle diffraction and double crystal diffraction). It was found, when the growth temperature is lower, the intensities of xray small angle diffraction peaks are modulated by a periodical function, which indicates that both sets of interfaces of the superlattice is highly flat; when the growth temperature is higher, the diffraction peak intensities are simply decay with the increase of diffraction vector, which indicates that one set of interfaces is highly flat but another is not; when the growth temperature is very high, the diffraction peaks are reduced more rapidly, which indicates that both sets of interfaces are not ideal.

本文详细介绍了用X-射线衍射（包括X-射线小角衍射和双晶衍射）方法对Ge〓Si〓/Si超晶格结构特性测试的结果，尤其是发现，当Ge〓Si〓/Si超晶格的生长温度较低时，X-射线小角衍射谱峰的强度随着衍射波矢的增加而周期性调制，表明超晶格的两套界面都十分平整；当生长温度较高时，Ge〓Si〓Si超晶格的X-射线小角衍射谱峰的强度随着衍射波矢呈简单的衰减变化，对应于超晶格内有一套界面不平整的情况；当生长温度进一步提高时，X-射线小角衍射峰明显减少，表明超晶格内两套界面都不理想。

In the Chapter 1 of this thesis, we gave brief introduction to the development of X-ray astronomy observations, which is one of the most important and active parts of modern astronomy. Due to the research experiences, we introduced ASCA X-ray satellite and Chandra X-ray Observatory in more details.

X射线天文学已经逐渐成为现代天文学最为活跃的部分之一，本文首先简单介绍了X射线天文观测诞生以来的发展经历，因研究经历的原因，我们对ASCA X射线卫星及Chandra X射线天文台进行了较详细的介绍。

When propagating light\|ray passes through two fixed points in the gradient index mediums and a cuspidal variable\|point （at this point the trace equation of propagating light\|ray is non\|differentiable） at the borderline of two different GRIN mediums, the mathematical relationship, which the trace equation of propagating light\|ray and borderline equation of two different GRIN mediums should satisfy, is derived by the Fermat's principle and calculus of variation.

当光线通过梯度折射率介质中两个固定点和两个GRIN介质界线上的可动尖点（光线轨迹方程的不可微点）时，由费马原理和变分法运算推得传输光线的轨迹方程与两种不同GRIN介质的界线方程应满足的微分关系式。

Crystalline β-BBO thin films were successfully prepared on (001)-oriented Sr 2+-doped α-BBO substrates by using liquid phase epitaxy, pulsed laser deposition and vapor transport equilibration techniques. The films were characterized by X-ray diffraction and X-ray rocking curve. The present results manifest that the β-BBO thin films grown on Sr 2+-doped α-BBO substrates have larger degree of orientation f value and smaller X-ray rocking curve FWHM than the ones grown on other reported substrates.

采用液相外延法、脉冲激光沉积法以及气相传输平衡法在Sr 2+：α-BBO(001)衬底上生长了质量优异的β-BBO 薄膜，对薄膜进行了X射线衍射测试以及双晶摇摆曲线分析，结果表明，采用Sr 2+：α-BBO单晶作为衬底制备的β-BBO薄膜具有高的择优取向度和低的半峰宽值。

Birefringence, or double refraction, is the decomposition of a ray of light into two rays (the ordinary ray and the extraordinary ray) when it passes through certain types of ma ...

光在晶体中传播时，再不平行于光轴方向上，由于e光和o光传播速度不同，而出现两个不同折射率的光的像，这种现象叫做双折射现象。
