远近光分区设计，绝佳的光型组合，拥有利剑般锐利的远光和均匀铺地的完美近光。
High and low light partition design, excellent combination, with a sword as a highlight of the sharp and uniform floor coverings - perfect low light.
根据多普勒效应，光被离子反射后，靠近激光器的光的频率会高于远离激光器的光的频率，（日常生活中，救护车警报器的音调随着车的远近也变化，就是这个道理）这才有可能测量先前对离子施加的力的大小。
(An everyday example of this effect is the change of pitch of an ambulance siren as it approaches and recedes.) It was thus possible to measure the force applied to the ions.
光环的直径不仅取决于产生它的星系的远近还与引力透镜的质量有关——质量越大光就弯曲的越厉害。
The diameter of the rings depends not only on the distance to the galaxies that caused them but also on the masses of those galaxies. The more massive they are, the more the light is bent.
