Results validated that larger size and larger refractive index of particles resulted in larger gradient and scattering force.
结果表明光学散射力和梯度力随着小球半径和折射率的增大而增大。
A photon carries a momentum of, so one may anticipate light to "push" on any object standing in its path via the scattering force.
研究人员称，光子带有动量，因此可通过散射力推动物体在路径上前进。
Here, we show that it is possible to realize a backward scattering force which pulls a particle all the way towards the source without an equilibrium point.
但他们发现利用向后的散射力牵引粒子向后运动在理论上是可行的。
