所以你可以,在飞船里用弹簧测量,物体质量，让它振荡,如果你知道弹簧常数，这也是实际操作中,所用的方法。
So you can actually measure the mass of an object using a spring on the shuttle and let it oscillate if you know the spring constant, and that's the way it's actually done.
运用一阶单时间常数低通函数模拟运算放大器的开环增益，对RC桥式振荡电路进行线性分析，得出最大振荡频率为运算放大器增益带宽积的16.67%。
The maximum frequency of RC-bridge oscillator is 16.67% of gain bandwidth product of amplifier analyzed based on a first-order single time constant lowpass function model.
一阶振荡导模的传播常数随着平板厚度的减小而增加，此性质与传统的金属包覆波导不同。
The propagation constant increases with decreasing slab thickness for the first-order oscillating mode, which is different from that in traditional metal-cladding waveguides.
本文进一步研究了这些系数随时间变化而趋于一个定值或在某一常数附近作周期性振荡，并给出容易检验存在唯一全局渐近稳定的正周期解的条件。
In this article we further study the cases in which the coefficients of the model vary with time and tend to definite values or vibrate periodically near certain constants and...
