查询词典 impulse wave

The effects of artificial viscosity coefficient and mesh density on simulation results were discussed. The larger artificial viscosity coefficients and coarser meshes can smear off peak pressure of shock wave severely, but affect impulse little.

讨论了人工粘性、网格密度对计算结果的影响：较大的人工粘性系数和较粗的网格会严重抹平冲击波峰值压力，但对冲量影响较小。

At last, the systems of continuous wave radar and impulse radar are developed based on simulations for modern radar.

在连续波雷达测量系统中，应用了基于线性调频信号的数字化多频测距改进算法，提高了雷达的测量精度。

Body weight is used as the basis for standardization to obtain ground reaction force values and impulse values. The original signal of EMG from Rectus femoris, Biceps femoris long head, Tibialis anterior and Gastrocnemius lateral head is processed by DASYLab 6.0 software to band-pass (10-500Hz), full-wave rectification and low-pass filtering (10Hz), after using the formula root mean square to get the root mean RMS value, divided by total gait cycle as the basis for standardization (100%).

肌电讯号由DASYLab 6.0软体分析股直肌、股二头肌、胫骨前肌、腓肠肌等肌群之原始肌电讯号后，进行10-500Hz的band-pass滤波处理，经全波整流上翻、10 Hz低通率波平滑化处理，再利用均方根（root mean square， RMS）公式运算后，可得均方根振幅，并以步态周期中最大肌电值进行标准化处理。

Pulse detonation engine is a new concept of propulsive engine which uses high temperature and pressure gas produced by intermittent or pulsant detonation wave to generate thrust. PDE has many desirable advantages, including high thermal dynamic cycle efficiency, low specific fuel consumption, high thrust/weight and specific impulse, simple configuration, and will become propulsive device of aviation and spaceflight aerocraft in 21st century.

脉冲爆震发动机是一种利用间歇式或脉冲式爆震波产生的高温、高压燃气来产生推力的新概念发动机，这种发动机具有循环热效率高、燃料消耗率低、推重比高、比冲大、结构简单等优点，将成为21世纪新型的航空航天飞行器的动力装置。

Sometimes his choice is non- rational, quite impulse, for instance when he a sword assassinates him under enraging 误以为 is King's wave Luo river 涅 Si.

有时他的抉择是非理性的，相当冲动的，比如当他在激怒之下一剑刺死他误以为是国王的波洛涅斯。

A successful analytical approach is conducted effectively by manipulating the "Dytran" software to simulate the phenomenon of plane shock wave impulse on metal boards, not only the cost and risk of experiments are reduced, but also the strain status is foreknown.

本研究中成功的发展出Dytran程式模拟震波冲击金属板的分析方法及有效模拟，除可减少实验的风险及成本，也可提早预测金属板受震波冲击的应变状况。

IV 43 If I were a dead leaf thou mightest bear; 44 If I were a swift cloud to fly with thee; 45 A wave to pant beneath thy power, and share 46 The impulse of thy strength, only less free 47 Than thou, O uncontrollable! If even 48 I were as in my boyhood, and could be 49 The comrade of thy wanderings over Heaven, 50 As then, when to outstrip thy skiey speed 51 Scarce seem'd a vision; I would ne'er have striven 52 As thus with thee in prayer in my sore need.

四 假如我是一片任你吹卷的枯叶，假若我是一朵随你飘飞的云彩，或是在你威力之下喘息的水波，分享你强健的搏动，悠闲自在，不羁的风啊，哪怕不及你自由，或者，假若我能像童年的时代，陪伴着你在那天国里任意翱游，即使比你飞得更快也并非幻想——那么我绝不向你这般苦苦哀求：啊，卷起我吧！

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
