Not only are many anatomical and physiologic measures being now demonstrated to show fractal characteristics, but the behavior of biological systems is being recognized not to be nicely periodic, and more likely to be unpredictable with any precision. This wandering or variability is not due to irregular inputs from external to the system but is inherent in the system itself, independent of noise, and is attributable to the nonlinearities and delays in the interactions between components of the system. It is the purpose of this project to take some of the methods being used for assessing chaotic system behavior, particularly those which do not show period doubling or bifurcations, and to develop their applications to physiologic systems related to cardiovascular mass transport, exchange and metabolism.

现在不仅有很多解剖学和生理学的方法 表现出分形特征，但其行为 人们认识到生物系统并不是很好的周期性的，而且 更有可能在任何精度上都是不可预测的。这是漫游还是 可变性不是由于外部对系统的不规则输入造成的 而是系统本身固有的，与噪声无关，并且 归因于相互作用中的非线性和延迟 在系统的组件之间。这就是这个项目的目的 对目前用于混沌系统评估的一些方法进行研究 行为，尤其是那些没有表现出周期加倍或 分叉及其在生理系统中的应用 与心血管物质转运、交换和代谢有关。
