而每经过一次碰撞，光子的温度会慢慢地趋近于色素分子的温度，进而降温至室温，而且光子在这一过程中不会消失。
But with each collision, the photons slowly assumed the temperature of the pigment molecules, cooling one another to room temperature without being lost in the process.
光子与矽原子发生零星碰撞并释放自由电子时，矽拉曼雷射的功率也会随之到达极限。
The power of a silicon Raman laser typically hits a limit as photons sporadically collide with silicon atoms and release free electrons.
当光子与一个分子碰撞时，可发生几种情况。
When a photon collides with a molecule, several things can happen.
光子没有质量，但是当它们碰撞到物体时仍然会传输动量。这是一种非常微小的动量。
Photonshave no mass but they still impart momentum when they strike an object... it's a tiny, tiny amount of momentum.
而且，在弱相互作用重粒子衰变成超级弱相互作用重粒子过程中，应该产生光子和电子等副产品，并且这些粒子也会与质量较轻的原子核发生碰撞，将它们撞碎。
In addition, the decay from WIMP to super-WIMP should have produced photons or electrons as a by-product, and these particles can smash into light nuclei and break them apart.
光子在硅线中碰撞跳跃，当触及某个特定的角度，它就被硅线吸收了。
Light bounces around within the wires and is eventually absorbed when it hits at the correct Angle.
