查询词典 reflections

In this thesis, we apply the equations of motion of steady Mach reflections and the oblique shock theory to derive polynomial expressions of the forms of f(r,Mo,P1) of downstream sonic and strong/weak separating conditions of reflected shocks of perfect-gas steady Mach reflections. We then obtain polynomial expressions of the forms of f(r,M0) for the limiting Mach angle condition of the above two expressions.

本论文首先应用稳态马赫反射流场运动方程式及斜震波关系式，推导出理想气体稳态马赫反射流场之反射震波下游之音速条件与反射震波之强弱分界条件之曲线解公式，并应用该曲线解公式来推导反射震波俱音速性质於Mach angle条件及反射震波俱强弱分界性质於Mach angle条件之公式。

Then, the multiple reflection viewpoint is used in nonreciprocal transmission lines, so the theory of small reflections for nonreciprocal trans mission lines is studied in a different way, the accuracy of the theory of small reflections is also verified, which can provide a theoretical basis for designing multi-section transformer.

将多次反射观点应用于非互易传输线，从而用不同的方法对非互易传输线的小反射理论进行了研究，并进一步对小反射理论的准确性进行了验证，从而为多节变换器的设计提供理论依据。

But internal reflections an the boundaries of active medium can drastically enhance the onset of ASE, particularly if these reflections lead to a close path, i.e., a ray that is reflected upon itself. In the case, we have a strong feedback mechanism and as soon as the gain in the laser medium exceeds the reflection losses parasitic oscillations will set in.

但自发辐射的存在使得放大器工作介质会在信号光到达前开始发射激光，并且工作介质边缘的内反射能显著增大ASE的发射，尤其当这些反射能导致产生封闭路径时更是这样，当激光介质内的增益超过损耗时，就建立起寄生振荡。

The immediate effect of multiple reflections is an increase in the sound intensity caused by the reflections.

眼前的多重反射效应是增加所造成的反射强度的声音。

Geometric optical theory and the tessellate scheme were used to develop an algorithm for creating virtual optical-mapping objects for both reflections and refractions that can render specular reflections and refractions in object space.

为了提高视点相关的镜面反射现象的绘制速度和绘制质量，提出了计算任意曲面反射光学映射虚物体的方法。

As the classical equation overestimates the number of reflections. So a revised equation to predict reflections is proposed.

扩散场理论对反射声数量的估计偏高，认为声像分布空间是连续的。

Meanwhile, Wu's study of the history of science demonstrates his reflections on and perfection of Kuhn's "anti-Whig" view of history. This provides great inspiration and thought-provoking ideas for comprehension of and reflections upon Kuhn's history of science.

同时，吴文俊所体现出的科学史研究思想还对库恩反辉格史观进行了反思和完善，对于解读并反思库恩的科学史观具有启发性和思想价值。

The downgoing component represents reflections from the sea surface while the upgoing component represents reflections and refractions from subterranean strata.

Refl. Glossiness: Controls the blurryness of reflection 1 means perfect mirror-like reflections, lower values produce blurry reflections.

反射模糊：控制反射的模糊程度，1意味着镜面反射，较低的值产生较模糊的反射。

The nth order perturbation corresponds to the nth order scatterings and reflections between the head and torso, therefore, for the conditions of the snowman model, the effects of the earlier three scatterings and reflections on HRTFs are important, and the contributions of the fourth-order and higher-order ones are neglectable.

由于 n 阶微扰在物理上是和头部和躯干之间的 n 重散射相对应的，因而本文的结果表明，在雪人模型的条件下，头部和躯干的前三阶多重散射对 HRTF 是重要的，四阶及以上散射可以忽略。
