查询词典 constraint

Despite a national trend toward economic integration, the needs of state making during this turbulent period of Shandong's history prompted local authorities to restrict the movement of specie across administrative boundaries, leading to marked regional variations in both the silver-copper ratio and local interest rates that illustrate a real political constraint on the spread of purely market forces.

We obtained the nasal deformation with three-dimensional reconstruction images and adjusted to separate the images of nasal cartilage, defined the form and structure of nasal deformation. Then we measured 10 cases of adult cadavers nasal alar, lateral and septal cartilage through modern mechanical measuring instruments, to obtain the elastic modulus of above three part structure of nasal cartilage, then to obtain more accurate nasal cartilage elastic modulus data through statistical analysis. At the same time, according to the relevant literature, we obtained nasal soft tissue biomechanical properties, mainly were elastic modulus and Poisson\'s ratio. Finally we established three-dimensional finite element analysis model of unilateral cleft lip nasal deformation, defined the model\'s constraint conditions and carried out biomechanical measurement and analysis of unilateral cleft lip nasal deformation.
