例句
- By sweeping a laser along the pipe to change the local wave speed, physicists might be able to create a horizon.
將雷射沿著(zhù)管路掃過(guò)，可以改變局部的波速，運用這種方式，物理學(xué)家也許可以創(chuàng )造出視界來(lái)。 - Furthermore, the non-dimensional propagation speed of an ISW declines and the dissipation of wave energy increases as the blockage parameter increases.
隨無(wú)因次障礙參數的增大，無(wú)因次波速減小，而內波的能量消散增大。
