请帮忙修改几个英文句子，编辑说这几个句子有问题，多谢了！！ 1 Now, non-volatile holographic storage to maintain the information for a long time in this photorefractive crystal. 2Recently, using two coherent recording beams in the presence of a sensitizing bean with good nonvolatile holographic storage was achieved in doubly doped Ce:Fe:LN crystals 3 The concentration of Mg2+ in the melt was changed form 0 to 3mol% (0,1,2 and 3mol%) 4 The unpolarized ultraviolet-visible (UV-Vis ) absorption and infrared transmittance (IR) spectra were measured to analyzed the defect structure of these crystals, ranging from300-900nm and 400-4000cm-1.respectively. 5 The effective UV-Vis and IR range fro later discussion were from 360-600nm and 3400 to 3560 cm-1. |

1 Now, non-volatile holographic storage to maintain information has been put into use for a long time in this photorefractive crystal. （该句没有主谓语，我加了has been put into use） 2Recently, the usage of （把using 改为the usage of）two coherent recording beams in the presence of a sensitizing bean(这里应该是beam 吧) with good nonvolatile holographic storage was achieved in doubly doped Ce:Fe:LN crystals. 3 The concentration of Mg2+ in the melt changed from 0 to 3mol% (0,1,2 and 3mol%) (去掉was,另外你把 from 写成form了) 4 The unpolarized ultraviolet-visible (UV-Vis ) absorption and infrared transmittance (IR) (前面两个单词的首字母缩略词不是IR吧？这两个的意思不一样哦) spectra were measured to analyze (analyzed 去掉d) the defect structure of these crystals, ranging from300-900nm to 400-4000cm-1.respectively.(把and 改为to, range from...to...) 5.The effective UV-Vis and IR range in（将fro 改为in） later discussion were from 360-600nm and 3400 to 3560 cm-1. 就这几个单独的句子，又没中文，有点难懂哦，我不是你这个专业的，只能看看语法什么的，也只能改这么多咯，不知道改的对不对，如果有不对的地方请指正。我把改了的地方给你标记出来了，因为以前别人也是这么要求的  |
