signal velocity的意思
signal velocity中文翻譯:
信號速度
velocity───n.【物】速度
signal───adj.顯著的;作為信號的;n.(Signal)人名;(瑞典)西格納爾;vt.標志;用信號通知;表示;n.信號;暗號;導火線;vi.發信號
velocity profile───速度剖面(圖),速度分布圖,速度變化圖
muzzle velocity───初速;出口速度;初速度(彈出膛時的速度)
constant velocity───常速度,等速度; 恒速;勻速;等速度;恒速度
angular velocity───[力]角速度
signal wire───[通信]信號線
radio signal───無線電訊號;無線電信號
cratering velocity───彈坑速度
Although previous studies have found that the "group velocity" of light can travel faster than c, the "signal velocity" -the speed at which information travels -cannot.───盡管先前的研究已經證實,光的“群速度”可以超越光速c,而“信號傳播速度”——光攜帶的信息的傳播速度——不能超越光速。
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.───科學家發現,單個光子的前驅波頭一般以光速c傳播,就像由大量光子攜帶的信號的傳播速度一樣。
In light of this finding, scientists have wondered whether single photons travel at the group velocity or the signal velocity.───在這些發現的基礎上,科學家曾經懷疑,是否單個光子可以達到“群速度”和“信號傳播速度”。
In light of this finding, scientists have wondered whether single photons travel at the group velocity or the signal velocity.
Although previous studies have found that the "group velocity" of light can travel faster than c, the "signal velocity" –the speed at which information travels –cannot.
