规则反射

In the false color composite image of TM7, 4 and 2, the dry farm is lurid, and is regular in the geometric outline.

旱地在TM1-4波段反射率较高，在TM5、7波段，反射率逐渐降低，在TM7、4、2合成图像上，呈米黄色，且有规则的几何外形，也较易区分。

They also have to read mirror image writing and scour through 6,000 pages of notes because sometimes Leonardo had his own patent inside his designs.

他们也要读反射字和从6，000页笔记中查找笔记，因为达文西有他自己一套的规则在他的设计中。

We have been looking at regular reflection from mirrors and other shiny flat surfaces.

我们已经看过从镜子或其它光滑表面的规则反射。

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。

In order to clearly recognize the geophysical response of carbonate reservoir,based on preliminary recognition of Ordovician carbonate reservoir under the basal surface in Tahe oilfield,some regular vug models and random arranged vug models were designed and built. The variable-grid finite difference method was used to simulate the seismic wave propagation in these models. Then,the seismic records of the models were analyzed and the effect to seismic reflections caused by vug is studied. The impact rule of regular vug scale and random arranged vug density on seismic attributes was obtained.

To resolve those problems, the nature of safety is expatiated by comparing the differences between safety and reliability, security, which would facilitate us to design some novel safety mechanisms. Based on multilevel safeguard mechanisms, the safety technologies of distributed mission real time system is deeply, systematically researched in this dissertation, some main works and contributiveness including:1 To improve safety of complex mission critical real time system by dividing and ruling way, the whole system usually is divided into few small and simple subsystems with different criticality.

One monolayer of CSB deposited on Au/Ge(111)-√3 at 220 K followed by cooling to 100 K leads to the formation of a well ordered (2×1) structure as observed by LEED.
