Simulation results show that in the alpha stable distribution assumption, multi-target direction estimation method is more reasonable and effective based on the spectralmeasure.
仿真结果表明，在稳定分布假设下，基于谱测度的多目标方位估计法是合理有效的。

And alpha is something that we can measure at distant places in the universe and thereby back in time by looking at these atomic spectral lines.
我们可以在宇宙里遥远的地方测量阿尔法常数，从而通过研究这些原子光谱线回到过去。

The spectral modulation sensor system can detect and measure various physical parameters such as pressure, temperature, gas density, and various chemical species.
