If the redshift is much less than 1 , we can calculate the receding velocity by the following formula 若红移z比1少得多则我们便可用以下公式找出星系的退行速度v ：
Transfer of anterolateral femoral vascularized fascial flap for treatment of degenerative arthropathy of knee 带血管蒂股前外侧筋膜瓣移位膝关节治疗退行性膝关节病
Decompression with and without fusion in the treatment of degenerative lumbar disease : a systematic review 单纯减压术与减压融合术比较治疗退行性腰椎疾病的系统评价
Adenovirus mediated human transforming growth fector - beta1 transduction in reversing degeneration of intervertebral disc in rabbits 1基因阻逆兔椎间盘退行性变的实验
Clinical effects of intraarticular injection with natr hyaluronic acid on degenerative osteoarthirtis of knee joint 关节腔内注射透明质酸钠治疗退行性膝关节炎疗效观察
Treatment of degenerative knee osteoarthritis with genu varus by tcd steaming and washing combined with orthopedic shoes 中药熏洗配合矫形鞋治疗退行性膝关节炎并膝内翻
Posterior lumbar interbody fusion combined with pedicle screw fixation for the treatment of lumbar degenerative stenosis 椎弓根固定及椎间植骨融合治疗腰椎退行性椎管狭窄症
This region can be the site of vascular , neoplastic , degenerative , congenital , or traumatological diseases 此区域可发生血管性、肿瘤性、退行性、先天性及创伤性疾患。
Treatment of retrograde affection of lumber vertebra with intervertebral fusion device and fixation over pedicle of vertebral arch 椎间融合器并椎弓根系统固定治疗腰椎退行性病变
Continuing the above example , the galaxy is moving at a speed of about 9000km s away from us , given the speed of light is 3x10 把数值代入，便可以得出以上例子的星系退行速度为每秒九千公里。
