摘要: A method is proposed for the detection of low-frequency spectroscopic transition in gaseous molecular ions by monitoring the motion induced by inhomogeneous fields at the sum frequency of harmonic motion in an ion trap and the transition frequency. Numerical examples are given....
A system having a harmonic frequency actuator system is provided including providing an actuator body, the actuator body having more than one set of fingers for generating a motion for a semi-rigid element, and attaching a high frequency actuator to the actuator body forming a harmonic frequency ...
The frequency pertains to pitch of the sound waves which determine the volume of the sound level. The frequency is inversely proportional to the wavelength. The wavelength changes if there is relative motion between the source of the sound and the observer....
1(a) shows, the antiprotons executed three types of harmonic motion: (i) harmonic axial motion along the direction of the magnetic field at frequency νz∼1MHz, (ii) trap modified cyclotron motion, a circular motion in a perpendicular plane at frequency νc′∼90 MHz, (iii) magnetron...
Even more than this, frequency and period are important concepts for describing any type of periodic motion, including simple harmonic oscillators like swings and pendulums, so learning about what they mean and how to calculate them is absolutely essential for mastering physics. ...

Moreover, FM sweeps in cats more dominantly activated non-primary auditory areas than the primary auditory cortex in a modulation rate-dependent manner20–22; however, the effect of the FM rates on the neural activity remains elusive in the human auditory cortex. The aim of the present study ...
称之为该运动的角频率(angularfrequency).ppt,* 等速圓周運動與簡諧運動 (SHM Simple Harmonic Motion) T為該運動的週期(period)。上述運動的週期為(繞一圈或角位移為2?所需時間)T=2?/?。習慣上,我們常以頻率(frequency) f來描述此週期性運動,f =1/ T = ?/2?,而?稱之為
Frequency, the number of waves that pass a fixed point in unit time; also, the number of cycles undergone during one unit of time by a body in periodic motion. A body in periodic motion is said to have undergone one cycle after passing through a series o
b When prepared in highly polarized (coherent spin) state, the atomic ensemble can be described as two-level system, thus exhibiting the behavior of a harmonic oscillator. Specifically, we can prepare the atomic oscillator with the effective negative mass, creating inverted spin population. c The...
