According to the plane cross section assumption, configuration of a rod is expressed as a history of the cross section with arc coordinate. A special solution which stands for equilibrium in straight line state is obtained from differential equilibrium equation. Linear perturbation equation is derived and its general solution is obtained in which the integral constants are determined by constrained conditions at two ends of the rod. The condition of existence of non zero solution of the integral constants gives to the Greenhill formula of exact elastic rod model, which shows that the boundary of stable area is a closed curve and of symmetry, and inference of shearable and extensible to stability of the rod is depend on three factors: difference between flexibility of shear and extension of a section of the rod, bending stiffness and the length of the rod.

Results In 9 cases of endometrial biopsy of materials by uterine curettage, the cells of endometrial stromal sarcomas of 6 cases were well differentiated and like stromal cells of endometrial hyperplasia; the cells of endometrial stromal sarcomas of 3 cases were poor differentiated, the cells of 2 were like that of malignant lymphoma, and another like that of pleomorphous sarcoma. In 9 cases were found the distribution of vessels cluster like endometrial corkscrew small artery. The tumor cells were grew along lymphatic or protruded in lymphatic, and there were small islands or small pieces of tumor cells in the interspace of muscles in 2 cases. The contrastive observation of the specimens of resected uterines of 9 cases confirmed the valve of above features to the confessed diagnosis of endometrial stromal sarcomas in the materials of endometrial biopsy or uterine curettage.

These were raised underinducing condition to test if any morphology and structure changes. Twenty two Arabidopsismutants had various changes in morphology and anatomical structures. Twenty mutants hadlow germination rate from 10% to 60%, of which 2 had survival rates at 0% and 50%. Fivemutants occurred structure changes in the hypocotyls or stem. One of these lines, namedarris-stem, showed some unique changes: slower growth rate in comparison with the wildtype from germination to florescence; serrated margin of leaf blades, spiral rosette; morebranch in the bottom part of the stem, shorter nodes, twisted stem and branch. There were oneor several arrises along the stem. Across sections of the arrises showed one or several compactcells lumps which were round, made up of several layers of cells, looked like vascular-bundle.
