Both the red shift of the plasmon absorption band and the sers effect result from the interparticle interactions of gold nanoparticles within the films 吸收峰红移及sers效应与薄膜中的金纳米粒子间的电磁耦合作用有关。
If the redshift of a distant galaxy is known , astronomers can determine the galaxy ' s intrinsic spectrum ( also called the rest - frame spectrum ) 假如已知遥远星系的红移，天文学家便可以量测该星系的固有光谱（即静止座标光谱） 。
Light from an object with this redshift was emitted about six billion years after the big bang , which is less than half the current age of the universe 从具有此红移的物体而来的光，约在大霹雳后60亿年就已发射出来，当时宇宙的年龄还不到现在的一半。
But if the inconsistent of the origin of the data and the uncertainty of the redshift are considered , the results are agreement with them 但若考虑我们样本中数据来源的不统一性，及发射线红移的误差等因素，则可以认为该结果与以往的结果基本保持一致。
On nights with moonshine or mild cloud cover , the telescope instead uses a pair of spectrographs to obtain spectra , and therefore redshifts , of 608 objects at a time 而在有月光或薄云的夜晚，望远镜则利用一对摄谱仪摄取光谱，可同时测定608个物体的红移。
