支点的

This model of compression fracture showed the different reseting-effects after imposing reseting-load at different fulcrum. The change of displacement is the most obvious when the reseting-fulcrum is at the top of spinous process of T_(12) vertebral, the mechanic feature of various parts of the injured vertebral is the most stable, but the stress of the zygapophysial joints is larger.

骨折模型在不同的过伸支点施加复位载荷后表现出了不同的复位效果，当过伸支点在T_(12)棘突顶点处时其位移改变最明显，受伤椎骨各部位的力学特性最稳定，但是小关节承受了较大的应力。

This condition is weaker than the conditon for complete topological conjugacy of two families of systems, so it is significant and useful for deducing from relatively simple systems or systems with known bifurcation points to the systems with unknown bifurcation points.

这一条件比两族系统完全拓扑共轭弱，因此是有理论意义的，可以使我们从相对较简单的或已知分支点状况的系统来推知未知系统的分支点。

A person lying on a bed of nails, will not be hurt when help up by the nail bed. This is because when a weight is supported by many fulcrums, the weight on each fulcrum is reduced.

钉床 观众平躺在钉床上，钉子可将人托起，而不感觉疼痛，这是因为将一个重物放在许多个支点上，每个支点所受的重量就会减少。

By using the boundary conditions of the statically indeterminate shaft with three fulcrums,the deflection curve square of the shaft is got;By utilizing the energy method to improve the calculation formula, the accurate first order critical speed of the statically indeterminate shaft with three fulcrums is obtained quickly.

通过满足三支点静不定轴的边界条件来求解基本方程，得到多跨静不定轴的挠曲线方程，并应用能量法改进了计算公式，快速准确地求得三支点静不定轴的一阶临界转速。

By comparing their consumptions of materials and deflexions, a suggestion that better effect can be achieved by enhacing its girder height and lessening its webs thickness for long span continuous through girder is presented.

至于连续梁桥，由于其边跨对中间跨的弯矩可起卸载作用，中间支点截面有负弯矩，使梁内所受弯矩沿梁长分布比较均匀，因而有利于充分利用支点附近的梁截面和梁内的预应力筋；此外，由于其桥跨在桥墩上连续，致使变形曲线匀顺，因而对高速行车有利。

Curve flexibility may dictate the degree of the fulcrum bending correction index, whereby a curve that is less flexible may achieve a greater fulcrum bending correction index.

曲线的弯曲度可能指明了支点弯曲矫正指数的程度，然而较不弯曲的曲线可能达到更大的支点弯曲矫正度指数。
