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。

A microring and a phase modulator are coupled to each arm of a normal Mach-Zehnder modulator respectively in order to compensate its sublinear characteristics transfer.

将一个微环谐振器和一个相位调制器分别加载到马赫曾德尔调制器的两臂，可以补偿普通马赫曾德尔调制器的亚线性，得到线性度良好的响应特性。

A numerical simulation was conducted for a fixed-geometry two-dimensional mixed-compression supersonic inlet with sweepforward high-light and "X" type missile configuration. The results indicate:(1) The total pressure recovery declines with the rise of the free stream Mach number, while the mass flow ratio rises firstly and then declines when its maximum value is obtained at the design point.

针对一种定几何二元倒置&X&型混压式超声速进气道开展了数值仿真研究，结果表明：随着来流马赫数的增加，进气道总压恢复系数下降，而流量系数却先上升，在设计点达到最大值后下降。

In this paper, The delta wing of Mach number 0.8 at an attack angle of 21. 8 degree is simulated by our program. Then, using the visualizing program, we map the figures of space streamlines, cross streamlines near the vortex axis, three dimensional vortex lines, cloud atlas for pressure and vortex and targer of particles.

在这一章里，我们先用所建立的计算软件数值模拟了来流马赫数为0.8、攻角为21.8°的三角翼的流场，之后以拓扑分析结果做指导，研制了一套数值显示流场、旋涡结构的软件，用该软件我们绘制了跨音速三角翼背风区涡轴附近截面流线、空间流线、三维涡量线、压力和涡量云图以及粒子屏痕图。

OK,dann mach doch einen Termin!

好，把你的父母约出来吧！

I go to school at night.

我是上上学。
