The results are unsure for experimental use;The rabbit's corneas that were removed with upper-half of corneal limbal epithelium lamella and erased the center corneal epitheliums were transparent with intact corneal epithelium;In the approach,the corneal and limbal epitheliums were burned with a cotton swab socked in 1 mol/L NaOH,there were 4 rabbits' corneal stroma happened perforation or ulcer and symblepharon,and the other one presented corneal epithelium phenotype.This is an applicable method to create the pathological model of corneal limbal stem cell total deficiency.

结果表明，处理后4周，全周角膜缘上皮板层手术切除，中央角膜上皮层用1 mol/L NaOH擦除的5只试验家兔角膜表面全部血管化、结膜化，未发生睑球粘连，角膜基质胶原纤维完整未见溃疡、穿孔等病变，细胞印迹学检查为结膜表型，可作为实验性角膜缘干细胞移植的病理模型；全周角膜缘上皮板层手术切除，中央角膜上皮用生理盐水擦除的5只试验家兔，有2只为结膜表型，另3只为角膜表型，观察期内结果不稳定；半周角膜缘上皮板层手术切除，中央角膜上皮层用生理盐水擦除的5只试验家兔，角膜表面透明，全部为角膜表型；直接用1 mol/L NaOH擦除角膜缘和中央角膜上皮的试验家兔，有4只角膜基质胶原纤维断裂、溶解，并伴有严重的溃疡、穿孔、睑球粘连等病变，不能用于移植试验，另1只角膜表面透明，未见结膜和新生血管长入，细胞印迹学检查为角膜表型。

The results show that the effect of small-sized hole and delaminations is not great . On the natural frequencies , the effect of t ransverse elliptical multiple delaminations around an elliptical cent ral hole is more serious than that of lengthways elliptical multiple delaminations around an elliptical cent ral hole ; the natural f requencies are very sensitive to damages location , and less sensitive to multiple delaminations' size and the holes'size.

结果表明：当穿孔和分层的尺寸较小时，其对层合板固有频率的影响很小；横向穿孔-多分层损伤对层合板固有频率的影响较纵向穿孔-多分层损伤更显著；平面编织层合板固有频率对损伤位置最为敏感，分层尺寸次之，穿孔尺寸的影响最弱。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
