查询词典 mirror reflection

Numerical results demonstrated that there are three kinds of the instability for the under-expanded supersonic jets according to their shock cell structure patterns:(1) the regular reflection shock cell with a single shear layer,(2) the Mach reflection shock cell with two shear layers and (3) the curved Mach stem with a relatively high expansion ratio.

计算结果表明欠膨胀超声速射流的失稳机制根据射流激波结构的特征可分为3种失稳模式：具有规则反射激波结构和单一剪切层特征的射流不稳定性；带有马赫反射激波结构和双剪切层特征的射流不稳定性；具有弯曲马赫杆和高度欠膨胀射流的不稳定性。

In this few decades, scholars paid attention to the research of Bragg reflection in regular waves. Thus, this study aimed to discuss the Bragg reflection in irregular waves. EEMSE is a numerical model based on evolution equation for mild-slope equation developed by Hsu et al.

以往关於系列潜堤之布拉格反射研究，在规则波方面的理论、数值研究与分析都渐趋成熟，而实际应用於海岸保护时需考虑波浪为不规则波，因此本文之重点在於探讨不规则波下之布拉格反射。

From the shadowgraphs, it is observed that the patterns of a plane incident shock wave reflected from the parabolic reflector can be either a regular reflection or a Mach reflection which depends on the shock wave strength and the reflector geometry.

由流场观察得知，入射震波强度较小、收敛角较小的，震波经反射体的反射型态趋向於正规反射，当入射震波强度增强、收敛角增大时，反射型态则会由马赫反射型态再转为正规反射型态。

The reflection of the LO mode, RLO, and its ratio, RLO/RTO, with the reflection RTO of the LO mode increase with increasing angle of incidence. In the case of the polarized incident light,ωLO is a function of angle of incidence and polarization state of the incident.

在45°入射角附近，ωLO几乎与入射光的偏振方向无关；在这个临近角45°两侧，ωLO和入射光的偏振方向的关系呈现相反趋势：当入射角小于45°，ωLO随着入射光极化仰角θ的增大而减小，当入射角大于45°，ωLO随着极化仰角θ的增大而增大。

So, researching the influence to reflection wave features made by the factors, such as sand and mud thin-bedding seismic reflection feature, the thickness of single layer in the thin-bedding group, the thickness of subroutine structure, the number of layers in the thin-bedding group, type of incident wavelet, main frequency, sampling rated has the moment current significance and theoretical significance in the qualitative or quantitative seeking of single layer's thickness or thin layer group's thickness in the thin-bedding and forecast of the space distribution laws of thin reservoirs.

目前我国东部的石油勘探工作已进入精细勘探阶段，如何确定陆相地层中薄储层的空间展布规律及其性质已成为一个亟待解决的问题，由于我国东部的绝大多数中、新生代陆相含油盆地大都以薄层砂、泥岩沉积为主，夹有少量薄层碳酸盐岩、页岩及膏盐层，地层岩性和厚度横向变化均较大，而且这些地层的厚度远远低于常规地震勘探的垂向分辨率，因此，从理论上研究沙泥岩薄互层地震反射特征、薄互层组内的单层厚度、子结构厚度、互层组内层数、入射子波类型、主频、采样率等各种因素对反射波特征的影响，将对我们定性或定量求取薄互层组中各单层厚度或薄层组的厚度、预测薄储层的空间展布规律有一定的理论和现实意义。

It is introspective that Unsid writes self-communion, introspection is in reflection bag, use reflection implementation, introspection can be pair of catoptric augment, both is not a concept.

unsid 写道自省就是内省，内省在反射包里，是利用反射实现的，内省可以算是对反射的扩充，二者不是一个概念。

The flow field structure over wedges of 30 o, 40 o and 50o by shadowgraph technique, and the sandpaper has been used to change the surface roughness of the model wedges. The shock reflection over wedges of 30o and 40o are of Mach reflection.

本实验使用影图法来撷取於斜角为30、40及50度之楔行体斜面上震波反射的流场结构，并利用砂纸来改变模型表面之粗糙度，从极度光滑至表面砂纸平均粗糙度为0.0174cm共做四组实验来进行分析与比较。

Single scattering plays adominant role in most cases from specular reflection to diffusing reflection.

在镜反射直到漫反射的大多数常见面散射现象中，单次散射都起了主导性的作用。

We can obtain the specular reflection component by separating the reflection components, and more determine the surface normal of the object and recover surface shape of the moving objects.

通过对反射光中两成分的分离得到镜面反射成分，可进一步判断光源的方向、颜色，并取得物体表面法线方向，为自动物体建模提供依据。

To sum this chapter,they is two kinds of light :the bounces,two type of light reflectionsThey is specular reflection and diffuse reflection

正是因为这句话，我才翻译成"反弹光"与"反射光"区别开来。有讨论就会有提高，只要是正常的讨论，都欢迎！

There had been a moment during the breakfast meeting, though, after the backslapping and the small talk and when all of us were seated, with Vice President Cheney eating his eggs Benedict impassively and Karl Rove at the far end of the table discreetly checking his BlackBerry, that I witnessed a different side of the man.

那次早餐会期间，在表示过关心和寒暄以后，我们所有人坐了下来，我注意观察了一下，副总统切尼面无表情地吃着班尼迪克蛋（Eggs benedict，源自美国，以英式松饼、火腿、水煮蛋以及荷兰酱组合而成），卡尔。罗夫在餐桌的远端谨慎地经常查看他的黑莓手机，我目睹了他所不为人知的一面。
