propagation direction造句
例句與造句
- Based on the relationship between elastic constants and sound velocities in composite material and measuring very few velocities of different propagation direction , the elastic constant matrix can be calculated out
依據(jù)復合材料中聲波速度與材料彈性常數(shù)之間的本構關系，測量不同傳播方向的少數(shù)幾個聲速，就可以得到其彈性常數(shù)矩陣。 - By using bpm , the problem is reduced from a second - order boundary value problem requiring iteration or eigenvalue analysis to a first - order initial - value problem that can be solved by simple " integration " along the propagation direction
和其他模擬方法相比， bpm將二階邊值問題簡化為一階初值問題，減小了計算的復雜性，縮短了計算時間，降低了對計算機硬件的要求。 - When pure shear wave propagate in anisotropy media , even thought propagation direction is parallel to the direction of aligned cracks , experimental results exhibit that only two kinds of shear - wave velocity can be measured - fast shear wave and slow shear wave neglecting polarization direction
這個實驗結果進一步表明，純橫波在各向異性介質傳播時，即橫波的傳播方向與裂隙平行，無論橫波的偏振怎樣改變，只能觀測到兩種橫波速度，快橫波和慢橫波。 - It's difficult to find propagation direction in a sentence. 用propagation direction造句挺難的
