查询词典 shock

The computation results agree with the experiment results very well. The muzzle flow field of an artillery with a muzzle brake is also simulated. The main characteristics and the mutual relations of shock waves in the muzzle flow field are obtained by the simulation. On the basis of the simulation results, the influences of the brake holes on the muzzle brake capabilities are analyzed.

对某口径火炮带有制退器的膛口流场进行了数值模拟，其结果反映了制退器内外流场的主要特征和冲击波波系之间的相互作用，在数值模拟的基础上分析了3排侧孔对制退器性能的影响。

At first, numerical simulation are made on the temporal developing gas-phase mixing layer where the convective mach number is in the region of subsonic(0.5) and transonic(0.8). For the temporal problem where Mc is 0.5, researches where the computational field contains different numbers of initial disturbances(so-called n period problem) are made respectively, and vortex's types of evolution in mixing layer including different numbers of initial disturbances are investigated; For the temporal problem where Mc is 0.8, the distinct shock let structure is obtained, and its mechanism is analyzed at the same time.

文中首先对对流马赫数为亚声速(0.5)、跨声速(0.8)的时间发展单气相混合层作了数值研究，对Mc为亚声速单气相时间发展混合层，分别研究了计算域包含不同数目的初始扰动周期问题，考查了不同周期数的混合层中涡的不同演化方式；对Mc为跨声速的单气相时间发展混合层，得到了清晰的小激波结构，同时分析了小激波的形成机理。

Culture Shock's Jason Fips spoke to Bill Monk's co-founder Gaurav Oberoi and began by asking where they got the idea for the website from?

文化冲突的杰森·菲普斯对话BillMonk的创建者之一高拉夫·奥博洛伊，第一个问题是，创办这样一个网站的主意是从哪里来的？

The modal tests of PCB and PCB assembly (free boundary condition and fixed boundary condition) were carried out. The equivalent elastic modulus and damping parameters of PCB can be gained, and the fixed boundary condition of finite element model was also determined. These will help to the following work. Second, drop impact tests of three different heights were carried out. Strains and acceleration responses of PCB were measured. Failed BGA packages of different test conditions were dyeing, and cross section analysis of failed solder joints was conducted. It was found in our drop tests that the root cause of lead-free solder joints under drop impact was the combined effect of mechanical shock and PCB bending vibration.

针对JEDEC标准试件的局限性，提出了设计便于统计学研究焊点可靠性的试验试件的构想，利用有限元模态分析方法确定并验证了用圆形PCB组件替代JEDEC标准试件的可行性；通过一系列模态试验和有限元模态分析，确定了圆形PCB组件的相关试验参数，这不仅为跌落碰撞下PCB组件有限元模拟确定了较为合理准确的有限元模型，而且为正确地评价跌落碰撞下PCB组件的可靠性问题奠定了基础。
