查询词典 medium wave

The results show that when gravity wave's propagating in the homogenous winds, the nonlinearity is stronger in the fair wind than in the contrary wind, the background winds change the propagation velocity and path, and when gravity wave's propagating in the homogenous winds, the vertical wavelength decreases, the average upgoing energy flux reduces which implies the ambient winds absorb the energy of the wave, realizes coupling of the different atmosphere layers.

结果表明，当重力波在均匀风场中传播时，非线性效应在顺风场中比在逆风场中更显著，背景风会改变重力波在水平方向的传播速度和传播路径；当重力波在剪切风场中传播时，重力波在垂直方向上平均能流随高度的增高而减少，表明背景吸收了重力波的能量，在重力波向上传播的过程中，实现了大气各层之间的耦合。

Testing results of piles under low strain integrity are normally interpreted using one-dimensional stress wave theory. While one-dimensional stress wave theory is acceptable for pile-driving analysis the responses of piles integrity tests can not be adequately simulated when the hammer and the incident wave length are small in relation to the diameter of the pile.

本文提出的Ku波段海表波高／潮位探测系统在测量精度和使用方便上优于沿用至今的波高计和浪潮仪。

Then we find out the exact bounded wave solutions for WBK equation in chapter four. According to the theory of dynamical system, we investigate the explicit exact traveling wave solutions of nonlinear wave equations by using the characters of the closed trajectory connecting equilibrium points and the relations between obits and traveling waves.

在对系统进行定性分析、了解了系统所有可能解的大致形态的基础上，论文第四章给出了WBK方程的精确有界解，应用动力系统理论，利用连接平衡点的闭轨线的特点结合轨线与行波之间的对应关系来研究非线性波方程行波解的有界性及精确的显式表达式。
