They "want" to oscillate at a given frequency in the same way that a violin string does — a small amount of energy fed into the system, in almost any form, creates the oscillation.
它们“想”以小提琴琴弦一样的方式在给定的频率上进行振动——在小提琴中，以几乎任何形式馈入系统中的少量能量产生了振动。
The regularity of the change of the unstable oscillation wave form and the structure of the power spectrum were analysed.
计算并绘出了非稳区域边界，分析了非稳振荡波形变化规律及其模结构。
Based on the character of off-axis and multi-pass amplification systems, the possibilities are analyzed that some part of the line could form optical oscillator and occur self-excitation oscillation.
根据离轴多程放大系统的光路特点，对产生谐振腔最可能的光路部分进行了自激振荡形成条件的分析，根据分析结果并结合实际情况采取了一些抑制自激振荡的措施。
The dynamical model and the oscillation-rotation model of particle are derived from the dynamical mechanism of spontaneously break symmetry, and its simplified form is a harmonic oscillator model.
简述了已知的粒子质量公式，由动力学的对称性自发破缺机制导出粒子的动力学模型和振动-转动模型，其简化形式是谐振子模型。
In receiving mode, through controlling DDS, it produces the local oscillation signal needed by down frequency conversion of the receiving signal. Then the DBF is used to form the receiving beam.
