大动脉中血液流动的中性扰动

本文在长波假定下用流体力学线性稳定性理论对大动脉中血液流动求出了一种中性扰动。结果表明，心室或瓣引起的扰动在一定条件下有可能量一种中性扰动，它可以沿着动脉管无变形地传播到动脉远端。这说明也许有可能提供一种通过在远离心脏的某些浅表动脉部位检测这种中性成动以了解心脏的某些功能的新方法。

A NEUTRAL DISTURBANCE OF THE BLOOD FLOW IN THE ARTERIES

In this paper, on the approximation of long wave, using the theory of hydrodynamics stability in the fluid mechanics to analyze the aortic flow, the author obtains a neutral disturbance in the blood flow. This result manifests the fact that under certain condition, the disturbance caused by ventricle or aortic varves can be a neutral one and can be transmitted through arteries until it reaches to the farther end. Thus, it reminds the author to devise a new method to acquire information abput the function of the heart through the measuring of the neutral disturbance of the blood flow.
