spatial adj. 1.空間的;在空間中存在[發(fā)生,占有位置]的。 2.占大篇幅的。 too spatial a theme for a book like this 要占很大篇幅,不是這本書所能容得下的主題。 n. -ity 空間性。 adv. -ly
velocity n. 1.迅速;快速。 2.速度,速率。 3.周轉(zhuǎn)率。 at a velocity of 100 miles per hour 用每小時(shí)一百英里的速度。 dart off with the velocity of a bird 像鳥一樣迅速飛跑過去。 drag-free velocity無阻力飛速,真空飛速。 escape velocity(克服地球引力的)第二宇宙速度,逃逸速度。 final velocity (發(fā)射物的)終速。 initial [muzzle] velocity(發(fā)射物的)初速[腔口速度]。 uniform [variable] velocity勻[變]速。
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(diǎn)和研究的目的在于,希望利用在血流動(dòng)力學(xué)方面的研究優(yōu)勢,用有限元方法對(duì)動(dòng)脈粥樣硬化的血流動(dòng)力學(xué)問題進(jìn)行數(shù)值模擬,研究動(dòng)脈粥樣硬化在生成和發(fā)展過程中的血流動(dòng)力學(xué)、血管壁生理及生物力學(xué)性能的變化規(guī)律,以及這兩種變化規(guī)律之間的相互作用與動(dòng)脈粥樣硬化的發(fā)生和發(fā)展的關(guān)系,通過大量算例的對(duì)比分析,以期在這方面作些基礎(chǔ)而有實(shí)際價(jià)值的工作。
