With several feet of car body in front of the driver, the energy of a crash can be dissipated and the suddenness of the change in velocity can be reduced, they say.
他们认为,如果驾驶员前方车体部分的尺寸能够达到几英尺长,就能消散碰撞产生的能量,降低速度变化的突然性。
The scientists found that the precursor wave front of a single photon always travels at c, like the signal velocity of large groups of photons.
科学家发现,单个光子的前驱波头一般以光速c传播,就像由大量光子携带的信号的传播速度一样。
The advancing velocity of combustion front is proportional to air injection rate. The air injection rate has no significant effect on oil recovery and air consumption.
燃烧前缘的推进速度与空气注入速率成正比,而提高空气注入速率对采收率和空气消耗量没有太大的影响。
