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.

基于平面截面假定，弹性杆的位形表达为截面的弧坐标历程，根据平衡微分方程得到了两端受力螺旋作用时的直线平衡特解，导出了线性化扰动方程及其通解，积分常数根据两端铰支时的边界条件确定，并根据其存在非零解的条件得到弹性直杆精确模型的Greenhill公式，表明稳定域为一对称的封闭区域，拉/压和剪切对稳定性的影响取决于：拉/压柔度与剪切柔度之差，抗弯刚度和杆长这三个因素

The formula of normal cross section bending resistance bearing capacity based on the assumption of plane deformation of the cross section, and the formula of oblique section shear bearing capacity according to its composition and deformation are suggested.

在平截面假定的基础上，提出了两者正截面受弯承载力公式；按墙体组成材料对抗剪承载力的贡献，提出了墙体斜截面受剪承载力公式；同时还提出了墙体侧向变形的计算公式。

Methods:43 patients including 10 with mitral stenosis associated aortic regurgitation, 12 with mixed mitral valve lesions and 21 with mixed mitral valve lesions and combined with aortic regurgitation were studied.MVA determinded by (1) two -dimensional echocardiography with a cross-sectional area in the short-axis view (2DE),(2) pressure half-time using formula of 220/PHT,(3) color Doppler flow imaging with a jet cross-sectional area in the short-axis view with planimetry,(4) CDFI with a color jet width at the mitral valve orifice in the apical four-chamber view and long-axis view, assuming an elliptic mitral orifice, compared with the orifice area of excised mitral valve during mitral valve replacement.

It is understood that the Taiwan cross-strait flights not many think should not be crowded routes have questions, but the other side pointed out that the Dongshan and Hong Kong after the flight control zones have other non-cross-strait flights, many hope that Taiwan will be able to draw a route other and find a new convergence point of entry and exit, Taiwan officials pointed out that Taiwan's airspace is very small, are we going to draw a route is not easy.

据了解，台湾方面认为两岸航班不多，不应该有航路拥挤问题，但是对方指出经过东山与香港飞行管制区的还有其他非两岸航班，希望台湾能够另外多划一条航路，并找个新的衔接点进出，台湾官员则指出台湾空域很小，要另外划一条航路并不容易。
