斜波調頻合成外差干涉相位檢測非線性分析 -
The doppler frequency can be obtained as a heterodyne or beat effect.
由於外差或頻差效應，能夠得到多普勒頻率。 -
The comic verse - writers and the cartoonists took hold of it with screaming laughter, and in the personal columns of society weeklies jokes were perpetrated on it to the effect that charley frensham told archie jennings, in confidence, that five lines of " ephemera " would drive a man to beat a cripple, and that ten lines would send him to the bottom of the river

Abstract : we have studied theoretically a beat effect in a four - level system due to fifth - order optical polarization, and considered the cases that the pump beams have either narrowband or broadband linewidth. we have found that the accuracy for the energy - level splitting measurement is determined by the homogeneous linewidths of the optical transitions. that is to say, this technique can achieve doppler - free precision in the measurement of the energy level splitting between two excited states which are dipolar forbidden from the ground state
文摘:研究了四能級系統中基於五階極化的拍頻效應，考慮了抽運光束為窄帶線寬或寬帶線寬的情形.發現其對能級分裂的測量精度決定於光學躍遷的均勻增寬.也就是說，這種技術在測量與基態是偶極禁戒躍遷的兩激發態之間的能級分裂時，可得到消除多普勒增寬的精度 -
Because the air - borne imaging system is required a far acting distance and the focal length of its optical system is long. influenced by the unsteady or moving platform mounted on plane, the change between the frames of image sequence is more. problems of image fuzziness and instability tend to be striking out, which becomes a bottleneck restricting the air - borne reconnaissance, collimation, evaluating beat effect
機載光電成像系統，由於要求作用距離遠，故其光學系統焦距長，受其載體姿態變化和振動的影響，圖像序列幀間變化過大，造成觀察者覺得模糊、不穩定，己成為制約空中偵察、瞄準、打擊效果評估等功能的瓶頸。 -
Thirdly discussing the rationality of design indexes and the restricted zone, searching the relationship between the effect and beat numbers of marshall, founding the relationship between specimens made by gyratory compactor and by marshall compactor
並對superpave控制混合料的體積指標、禁區和控制點存在的必要性、馬歇爾擊實次數對擊實效果的影響、馬歇爾擊實試驗和旋轉壓實的關系進行了探討。 -
The effect of dynamic balancing and the stability of the new method precede the without resolving beat method
經過大量試驗驗證，這個方法比用不解拍的方法無論從穩定性還是減振效果上都很優越。 -
In theoretical analysis, the effect on receiving signal by radial beat of galvanometer is given qualitatively
理論分析中定性的給出了振鏡轉軸的徑向跳動對信號接收的影響。
