pulsation

By fem , the numerical simulation was carried out according to such models , many important hemodynamic variables , such as the tempo - spatial velocity field at every cross section of the artery , the pressure distribution , the secondary flow and the wss ( wall shear stress ) at the specific areas were obtained , which will help understand the biomechanics of coronary atherosclerosis furtherly . many investigators studied the stenotic artery by means of 2 dimensional models , which can only simulate the planar pulsatile waves and got , to some extent , some general results of the blood flow without considering the secondary flow and the reality of physiological conditions 本文的著眼點和研究的目的在于,希望利用在血流動力學方面的研究優勢,用有限元方法對動脈粥樣硬化的血流動力學問題進行數值模擬,研究動脈粥樣硬化在生成和發展過程中的血流動力學、血管壁生理及生物力學性能的變化規律,以及這兩種變化規律之間的相互作用與動脈粥樣硬化的發生和發展的關系,通過大量算例的對比分析,以期在這方面作些基礎而有實際價值的工作。

One cardiac cycle is divided into 50 parts in the transient analysis to accurately simulate the continuous pulsatile blood flow in the coronary artery , the hemodynamic parameters of the atherosclerotic and the controlled models at each of the 50 moments were computed in accordance with the physiological condition 這些計算包括:脈動流情況下的非狹窄和狹窄不對稱性對狹窄流場的影響,分岔角度變化時動脈狹窄和非狹窄的各種血流動力學參數的計算模擬。

A cornstarch - water slurry was driven by a pulsatile pump through tubing to simulate the blood flow within the heart , and the tubing was cyclically moved by a piston to simulate the heart motion 結果在模擬心臟運動作用下,原來的模擬血流波形已不存在,代之以模擬心臟運動和模擬血流按速度矢量相加規律所組成的復合波,而模擬心臟運動所產生的多普勒頻移信號的振幅和頻率都未改變且與上述血流信號并存于頻譜中。

Conclusions it is not easy to make a definite diagnosis of aef . so all the patients who have pulsatile aneurysms in the abdomen , acute pain on the lumba or the back and repeated small amounts of upper gastrointestinal haemorrhage , should undergo laparotomy without delay 結論術前確診腹主動脈腸瘺不容易,凡患者腹部有搏動性動脈瘤,腹部或背部劇烈疼痛,上消化道少量多次出血,應積極手術治療。

In the research work , finite element analyses is adopted to study the velocity wave and the secondary flow of nonlinear pulsatile flow in the s - shaped curved arteries 本課題采用有限元分析方法研究非線性脈搏波在s型血管中的速度波,二次流。

We also hope that the work could provide much more and more comprehensive theoretics foundations for the research of pulsatile flow in the curved arteries 也同時為彎曲血管中脈搏波傳播的研究提供更多更全面的理論基礎。

Led light source includes red , yellow , blue , green , white , purple , cyan , and full color ect , and it can display the gradual change , pulsatile change and so on 黃藍綠白紫青七彩等,可實現漸變跳變等多種色彩組合。

We present a woman who had been bothered by pulsatile tinnitus of the right ear which resulted from carotid artery stenosis 我們報告一例因為頸動脈血管粥狀硬化,導致其右耳脈動性耳鳴。

The research work in nonlinear pulsatile flow and nonlinear pulse wave propagation is reviewed 本文首先回顧了前人在彎曲動脈中脈動流和脈搏波傳播方面的研究工作。

Pulsatile tinnitus has various etiologies , including atherosclerotic carotid artery disease 摘要引起脈動性耳鳴的病因很多,其中包含頸動脈血管的粥狀硬化。
