弧长

The long parallel rays slanting across the top of the above radio image are known collectively as the Galactic Center Radio Arc and jut straight out from the Galactic plane.

斜穿过这幅射电图像上方的的长平行线合称为银河系中心的射电弧，这些弧刚好从银盘穿出。

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

Bladder contraction was very quickly initiated by trains of stimuli(1 000 mV,10 Hz,2 s)of the right L5 dorsal root and bladder pressures increased rapidly to 65%of normal, and bladder contraction induced by knocking the right patellar ligament was increased to 51%of normal through the new reflex arc in 4 canines after 6 months of operation.

体神经的运动传出支通过轴突再生能够长入自主神经的副交感性纤维，并具有良好的传导运动兴奋的功能；利用截瘫平面以下健存的体反射，通过硬膜囊内神经根吻合的方法，可建立人工膀胱反射弧，实现患者的控制性排尿。

The somatic motor axons can be regenerated into the parasympathetic endoneurial tubes of autonomic nerve.Using the survived somatic reflex under the horizon of spinal cord injury to reconstruct the bladder autonomic reflex arc by intradural microanastomosis of ventral root is practical in the canine model and may have a potential of clinical application.
