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.

有3例分化差者，其中2例酷似恶性淋巴瘤，1例酷似多形性肉瘤。9例均见簇状分布的子宫内膜螺旋小动脉样的小血管分布，2例见瘤组织沿淋巴管和突入淋巴管内生长及小片平滑肌组织的肌间隙内有小灶状或小片状瘤组织分布。9例子宫切除标本的对比观察，进一步证实了上述特征对宫内膜活检或刮出物确诊子宫内膜间质肉瘤的价值。

Moreover, the theory overall looked that, still wasat the rough stage, first was its basic parameter determination alsomust depend upon many experiences algorithms and the empirical data, roller distance, roller diameter, Next is many technical phenomenalike spiral curved waste product, the noise, theslanting roller characteristic, the slanting roller rollershape characteristic, the distortion match characteristic andso on all lacks the theory elaboration; Is once more the theoryconcise quality is insufficient, set of formulas not only cannotinclude each kind of cross section molding, even cannot include thesimilar cross section but the size and the material quality differentwork piece, like the curved distance and so on all lacks the generalexpression with the curvature.

另外，就矫直理论的总体来看，仍然处于粗糙阶段，首先就是其基本参数的确定还要依靠许多经验算法和经验数据，如辊数、辊距、辊径、压弯量及矫直速度等；其次是许多技术现象如螺旋弯废品、矫直缩尺、矫直噪声、斜辊矫直特性、斜辊辊形特性、拉弯变形匹配特性等都缺乏理论阐述；再次是理论的概括性不够，一套公式不仅不能包括各种断面型材，甚至不能包括同类断面而尺寸和材质不同的工件，如弯距和矫直曲率等都缺少通用表达式。

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.
