研究了弱驱动光机系统中声子辐射的相关统计特性。用散射理论解析地确定了三个主要的散射过程，用数值方法确定了主方程，它们之间的相互作用决定了声子的统计性质。我们的结果表明，对于大失谐量，与系统失谐的驱动场导致了两个反聚束声子的小发射率。对于共振驱动场，存在较大的两个聚束声子发射率。
We study the correlation statistics of phonon radiations in a weakly driven optomechanical system. Three dominated scattering processes are identified by the scattering theory analytically and the master equation numerically, whose interplay determines the phonon statistical properties. Our results show that for the large detuning, the driving field off-resonant with the system induces a small emission rate of two anti-bunched phonons. For the resonant driving field, there is a relatively large emission rate of two bunched phonons.
