查询词典 mach angle

Through the simulation and analysis, the thermal characteristics of the medium and the thermal effects of laser beam are obtained. A superior pump cooling structure was selected and designed, and it is to be demonstred in this dissertation. 2 The thermal distortion effects in the slab mediam are experimently studied using auxiliary lens、Shearing Interferometer and Mach-Zehnder interferometer.

A strictly nonblocking 4×4 matrix optical switch based on the switching units of Mach-Zehnder interferometer and Banyan network was proposed.

提出了一种基于Mach-Zehnder干涉仪结构开关单元和Banyan网络的严格无阻塞4×4矩阵光开关。

We learn from II Mach., ii, 13, that at the time of Nehemias there existed a collection of books containing historical, prophetical, and psalmodic writings; since the collection is represented as unifrom, and since the portions were considered as certainly of Divine authority, we may infer that this characteristic was ascribed to all, at least in some degree.

我们从二马赫。第一，二， 13 ，在时间内赫米亚斯存在藏书含历史， prophetical ， psalmodic著作；以来收集的是派均匀，而且由于部分，被视为当然的神权威，我们可以推断，这一特点是归功于所有的，至少在一定程度上。

For the large-amplitude dust-acoustic waves, the range of the Mach number for the existence of soliton propagation has been obtained and it is shown that the compressive and rarefactive solitons can coexist in the dusty plasma.

该研究工作除了对本领域的基础研究作出贡献外，在控制尘埃污染问题和用电磁波诊断尘埃等方面有一定的指导意义。

The calculated results indicate that a bifurcated A. wave can be formed when the shock passes through the flame, and pre-induced shock transmission in the flame leads to the formation of Mach stem, followed by spheral shock wave. The Rayleigh-Taylor and Kelvin-Helmholtz instabilities occurred in the flame induced by shock wave lead to the flame distortion and breakup.

计算结果表明，激波掠过火团时，分叉形成λ波；前引激波在火团内透射并在轴线处碰撞形成Mach杆，进而逐渐发展为球形激波；火焰在激波作用下先后出现Richtmyer-Meshkov不稳定和Helmholtz不稳定，火焰逐渐变形以致破碎；燃烧速率因此剧增。

An experiment on forming of cross-hatch on the ablation material surface has been done under the condition of Mach 5 and tur-bulent boundary layer regime.Artifitial disturbances created by randomly setting several pins along a line perpendiculer to the flow direction have shown stochastical character of local cross-hatch and independence of global orderly structure,therefore the pattern appeared fractal behavior.

在外流M＝5湍流边界层状态下，模型为170×300mm￣2蜂蜡平板上进行了烧蚀花纹图案生成的实验研究，通过实验证明了人工安置干扰源并不影响烧蚀材料表面花纹的有序结构，对大面积烧蚀花纹的分析表明，局部花纹结构具有随机性质，因此烧蚀花纹具有分形结构的特性，用分形方法可以大致模拟花纹生成图案。
