摘要：
Macroscopic deformation of biological tissue shows the various behaviors of nonlinear, aeolotropic and so on. The mechanics of the deformation generally depend on the chracter of the microscopic cells which have complicated structures like substratum, membrane and wall. In the cells, the strain caused by macroscopic deformation is unevenly distributed because of its structures. But the structures cause difficulity in the observation of the strain distribution and the study on the deformation mechanics of the tissue. In this study, birefringence microscope is applied to observe the uneven distribution of the strain. The technique of the microscope with CCD has abilities to evaluate the phase difference and the azimuthal direction, and to observe the value distribution. The uniaxial and biaxial tensile testings and the some consideration are carried out to investigate the deformation mechanics of the tissue of a plant by using the microscope system.
