| 研究了非空紧致度量空间上连续映射f·X→X,g?X→X的双重逆极限空间上移位映射σf·σg:lim(X,f·g)→lim(X,f?g)的一些性质:如果f,g为满射,那么移位映射σf·σg为弱刚性的（一致刚性的）当且仅当f?g为弱刚性的（一致刚性的）;f?g为几乎等度连续的,那么σf·σg也是几乎等度连续的. |

| Abstract: |
| Some properties of shift mappingσf·σg:lim(X,f·g)→lim(X,f?g) over double reverse limit space of continuous mapping f·X→X,g?X→X over non-empty compact metric space are studied,if f,g is surjection,then shift mapping σf·σgis weak rigidity(uniform rigidity)if and only if f?gis weak rigidity(uniform rigidity),f?g is almost equi-continuous,then σf·σg is also almost equi-continuous. |
| Key words: double reverse limit space shift mapping weak rigidity uniform rigidity almost equi-continuity |
