中文摘要：

在一个折迭的试管的自我刺激的摆动是在生理学的重要现象。在一个薄墙的折迭的试管的自我刺激的摆动的一条试验性的途径被使用高发射度和低幼仔模量硅酮橡胶试管开发。有弹性的试管被在我们的实验室的离心的扔的方法生产。为沿着试管的纵的方向在某个位置记录代表性的区域的进化的一个光方法基于折射索引匹配的技术被开发。与透明试管，试管法律在静态的没有流动条件下面被测量。当房间压力被增加，在试管的中间的位置的生气的节从一种伪通报配置转到一个椭圆，然后到 dumbell 形状。在自我刺激的摆动期间，二个周期的自我刺激的震荡状态和一个过渡震荡状态被识别。他们都属于陆模式。这些不同震荡状态与下游的 transmural 压力的差别引起的试管的起始的代表性的形状有关。

英文摘要：

Self-excited oscillation in a collapsible tube is an important phenomenon in physiology. An experimental approach on self-excited oscillation in a thin-walled collapsi- ble tube is developed by using a high transmittance and low Young＇s modulus silicone rubber tube. The elastic tube is manufactured by the method of centrifugal casting in our laboratory. An optical method for recording the evolution of the cross-sectional areas at a certain position along the longitudinal direction of the tube is developed based on the technology of refractive index matching. With the transparent tube, the tube law is measured under the static no-flow condition. The cross section at the middle position of the tube transfers from a quasi-circular configuration to an ellipse, and then to a dumbell-shape as the chamber pressure is increased. During the self-excited oscillation, two periodic self-excited oscillating states and one transitional oscillating state are identified. They all belong to the LU mode. These different oscillating states are related to the initial cross-sectional shape of the tube caused by the difference of the downstream transmural pressure.
