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.
