本文以MJ317型木工杠杆压砣张紧系统的带锯机改造成弹性挺杆张紧系统的带锯机为研究对象，通过对带锯机弹性挺杆式张紧系统的弹性动力学分析，运用拉格朗日定理建立了张紧系统的动力学模型，并应用现代控制理论将模型转换成数学模型。

In the scope of our life made cards and membership cards are made of a circle or rounded corners or other irregular situation, this is when the business card printing and membership card up forming post-pressure sected, in which the effect of cutting way is to become a wooden model and then separated from the surrounding steel blade edge around it, and then be immediately arotic post-pressure sected.

在吾人生活范围里制卡和会员卡制作物经常有圆形或圆角或其他不规则情形，这是当制卡和会员卡制作完毕后压切成型的效果，此种压切方式是先装成一个木制模型然后由周围以薄型钢片刀顺其边缘围绕，再加以紧搏后压切。

He takes a bite. She studies each word separately. She holds her voice as close to herself as she can. It is like pressing a pillow against her chest, the way the boy in the picture presses the book to his sailor suit.

He takes a bite，她把这句话拆开来一个一个词地学，她把声音放得不能再低，只有自己能听见，如同有个枕头紧压着她的胸口，就好象画上的男孩抱着书，让书紧紧贴着水手服的样子。

The Levy style Cable Dome model is made up of 〓5 tension piano-wires and 〓32×1 5 compressive steel pipes, distance between nodes and the tension force of cables is adjusted by screw up and down the turnbuckle The procedure of shaping up included four ways, and the loading included fully loaded and half loaded, to validate the influence of unconservative property, the author carried through the slack procedure and the unload procedure.

该Levy型索穹顶模型，以受拉的〓5高强钢丝和〓32×1.5受压钢管构成，节点间拉索的长度以及拉索的预拉力通过拧紧或放松花篮螺丝来调节。试验内容包括成形试验和承载力试验，成形试验尝试了四种不同的成形方法，为了考察结构非保守性的影响，每种成形方法成形后，还逆序进行了结构的松弛试验，荷载态试验包括均布荷载满载（即在所有压杆上部节点施加集中荷载）和半载（在结构1／2的压杆上部节点施加集中荷载）的加载和卸载时结构工作性能的测试。
