入射

Photoluminescence properties of ZnSe/silica gel-glasses were investigated by an advanced spectrum system. Excitated by laser of two different wavelength, the electron transition occurred in two different relaxation approaches. Interband radiation spectra and the surface defect radiation spectra of ZnSe nanoparticles were obtained. The correlation between the wavelength of eradiated light and the incident light verifies that the electronic-hole structures change with the size of the nanoparticle.

利用先进的稳态光谱测试系统研究了ZnSe/SiO〓凝胶玻璃纳米复合材料的光致发光特性，凝胶玻璃基纳米复合材料样品中观察到不同波长激发光激发样品，导致激发态电子经两种不同的弛豫途径的辐射跃迁发光，即ZnSe纳米粒子的带间发射光谱和ZnSe纳米粒子的表面缺陷态发光，辐射光的波长与入射光的波长是连续相关的，证实了凝胶玻璃中ZnSe纳米粒子存在随尺寸变化分立的能级结构。

The greater the proportion of incident light that is reflected at the same angle as it strikes the surface, the glossier the surface apperas.

以同样角度入射到表面的光被反射的越多，表面光泽度就越强。

The greater the proportion of incident light that is reflected at the sameangle as it strikes the surface,the glossier the surface appears.A surface that scatters light randomly has a diffuse appearance.Paper gloss depends mainly on smoothness and the type of surface coating applied.It can also be altered by finishes,such as varnishing and laminating.

These two sets of neutron optical potential parameters have been ingathered in the Nuclear Parameter Data LIBRARY of China by Chinese Nuclear Data Center.Based on these neutron optical potential parameters, program DWUCK4 has been applied to calculate direct inelastic cross sections which are used in SUNF program as input data and then the SUNF program has been used for calculating all nuclear reaction data of neutron induced on 135Ba, 136Ba, 137Ba, 138Ba and 130Te in energy range from 0.01 to 20MeV, respectively.

在这两组中子光学势参数的基础上，应用程序DWUCK4计算了直接非弹截面，作为输入数据用于SUNF程序，用SUNF程序计算了中子入射~(135)Ba、~(136)Ba、~(137)Ba、~(138)Ba和~(130)Te五个核的反应全套数据。

When infrared ray irradiates to the surface of material and radiating frequency is same as material molecular frequency, the radiating energy is strongly absorbed by the material.

红外辐射是辐射物体以电磁波的方式传播内能的过程，当红外线照射到某一物体时，如果入射的红外线频率和物体分子固有频率相一致，则物质分子就会表现出对红外线的强烈吸收，吸收的那一部分能量就转化为分子的热运动，使物体温度升高，达到加热干燥的目的。

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。

The irradiating style of laser relative to the flying cylinder has to be considered whether the laser is from land or air.

当激光无论从地面或是从空中辐照运动的圆柱体时，都涉及到入射激光相对于圆柱体的辐照方式。

Naturally, the expression for oblique incidence is more complicated

倾斜入射的公式当然要更复杂些。

Dielectric cylinders of unknown permittivities are buried in one space and scatter a group of unrelated waves incident from another space where the scattered field is recorded.

设一未知的不均匀双轴性介质复杂物体掩埋在其中一空间中(不论是在半空间或三层空间中)，吾人可在另外的空间中适当的安排一组具有不同入射和极化方向的无关联波照射物体并量测在此之散射场，利用简单的矩阵运算，我们就可以克服非线性和不良情况的发生的困扰，进而重建双轴性复杂物体的介电常数分布。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
