用簡正波方法分析聲波在海水中的傳播特性Using the two - stream fluid model, the linear dispersion relation is derived assuming a two - dimensional spatial geometry. two cases are considered, one is that the 2d spatial geometry is defined by the plane containing the two counterstreaming electron populations and the perturbation wave vector ( referred as the xy plane ), and the other is that the geometry is defined by the plane being vertical to the two counterstreaming electron populations ( referred as the yz plane )
對高能束流和電子迴流構成的雙流系統,建立冷等離子體流體模型,採用簡正模分析方法,分別考慮擾動波矢在平行於電流傳播方向的平面(記為xy平面)上和在垂直於電流傳播方向的平面(記為yz平面)上這兩種情況,推導了不穩定性的色散關系。The thesis mainly deals with the third part of across : " sompi " cepstrum methods. the principle and system structure of across a re first introduced. the propagation of wave in media is simply studied and its transfer function in frequency domain is modeled as superimposed damped exponential sinusoids, each damped exponential sinusoid is called as a wave element and its exponential index part consists of two factors : group velocity travel time and decayed factor
為此,首先介紹了across的原理與組成和通過簡單地討論地震波在介質中的傳播情況建立起介質的傳遞函數模型,指出:在一個狹窄的頻率窗口裡,介質的傳遞函數可以用有限個阻尼正弦項的疊加的形式表示,每個阻尼正弦項代表一個波成分,其指數部分包括兩個因子:波成分在介質中的傳播時間和衰減因子。Adopting relatively simple mechanical model and predigested boundary condition and taking a straight bar applied one end with an semi - sine impulse to simulate the rigid target impacted by a projectile as an example, the relation between the stress wave propagation and acceleration of projectile has been analyzed by theoretical deduction and computer simulation
摘要採用較為簡單的力學模型和簡化的邊界條件,以直桿一端施加一半正弦載荷脈沖和模擬彈體沖擊剛性靶為例,用理論推導和計算機模擬的方法分析應力波傳播和彈體加速度的關系。分享友人
