查询词典 shock-headed

Compared with the initial value problems of scalar conservation laws with smooth flux function, the global weak entropy solutions for the initial-boundary value problems of scalar conservation laws with weak discontinuous flux function include the following new interaction types: a rarefaction wave collides with the boundary and is absorbed compltetely or partially by the boundary; a rarefaction wave collides with the boundary and the boundary will reflect a contact or non-contact shock wave; a contact or non-contact shock wave collides with the boundary and is absorbed by the boundary; a contact or non-contact shock wave collides with the boundary and a new non-contact shock will rebound from the boundary simultaneously or later.

与具有光滑流函数的单个守恒律的初始值问题相比，具有弱间断流函数的单个守恒律初边值问题的整体弱熵解中包括下列新的相互作用类型：稀疏波碰到边界并被边界部分或全部吸收；稀疏波与边界相撞，边界反射出一个接触或非接触激波；接触或非接触激波碰到边界并被边界吸收；接触或非接触激波与边界相撞，边界同时或稍后反射出一个新的非接触激波。

冲击作用下设备安装基座响应的冲击余谱的一般计算方法是先计算冲击作用下设备安装基座的时域响应，再计算安装基座响应的冲击余谱。

To obtain a complete picture about shock formation in non-viscous flow, in the succeeding chapter we investigate the isothermal shocks in adiabatic flows. We find that in this case the shock solution still exists, but the structure and the properties of the solution are greatly different from above even qualitatively. In some region of the parameter space there only exists unstable shock solution and in some region of the parameter space there may exist two stable shock solutions.

为得到完整的无粘流体中激波形成的图象，在接下来的第四章，我们研究绝热流体中等温作为激波条件时的情况，发现此时激波解仍存在，但解的结构和性质甚至在定性上都与前两章有了显著的不同：某些参数空间只存在非稳定的激波解，某些参数空间则会同时出现两个稳定的激波解。

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。

However,it is the dissipa-tive mechanism,i.e.the mechanism of energy localization that attracts one′sattention for the problem of shock initiation.Since the test result of shock initia-tion about fine-grain explosive charge does not support hot spot ignition model,the author of this dissertation advances that the mechanism of energy localiza-tion is coincident with phonon-fracton crossover of fractal network for ultra-fine-grained charge and,moreover,analyzes the relation between shock sensi-tivity and porosity,which is consistent with shock Hugoniot curve for porousmaterials.

由于超细颗粒压装炸药的冲击起爆实验不支持热点点火模型，为此、本文提出对于单晶颗粒半径为微米以下量级的药床，冲击起爆的能量局域化机制与分形网络中弱局域化声子向强局域化分形子的渡越对应，并且根据这一机制分析了超细颗粒药床的冲击感度和孔隙度的关系，结果与多孔物质冲击压缩的P-V图吻合。

From an extensive molecular epidemiological surveillance around the H5N1 infected regions in the past several years, H5N1 viruses were isolated from the wild birds, eg. Bar-headed goose, brown-headed gull, great black-headed gull and common cormorant form Qinghai province and tree sparrow from henna province.

Likewise, there were three main forms of government, each supported by a social "principle": monarchies (free governments headed by a hereditary figure, e.g. king, queen, emperor), which rely on the principle of honor; republics (free governments headed by popularly elected leaders), which rely on the principle of virtue; and despotisms (enslaved governments headed by dictators), which rely on fear.

同样的，存在三种主要的政府形式，每一种由一种社会&原则&支撑：君主制（以一个继承的人物，比如国王，王后或皇帝为首的自由政府）依赖于荣誉原则；共和制（以大众选举的领导者为首的自由政府），依赖于美德的原则；独裁制（以独裁者为首的奴役政府），依赖于恐惧。
