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。
On the basis of fvm and unstructured grids , tvd ? muscl scheme is constructed with high performance . according to the discharge and water level of breach , the scheme is used to compute velocity and water level of center node of all elements 在應(yīng)用有限體積法無結(jié)構(gòu)網(wǎng)格的基礎(chǔ)上建立了高性能的tvd ? muscl格式,根據(jù)堤壩潰口處的流量、水位,計算出沿程下游各點的流速、水位。
Using matlab and its add - ons simulink , through establishing simulation maths model , the paper integrates open chain vector equation ( describing motion restriction ) , numerical value simulation ( computing velocity and displacement while given acceleration ) and matrix algebra , etc . to accomplish dynamic simulation for the robot and verifies the results for kinematics of the robot using analysis method , and it establishes foundation for following study for the robot such as kinetics , control , etc 利用matlab及其附加軟件simulink ,通過建立仿真數(shù)學(xué)模型,綜合開環(huán)矢量方程(描述運動約束) 、數(shù)值仿真(在加速度已知時計算速度和位移) 、以及矩陣代數(shù)等來完成機(jī)器人動態(tài)仿真,對所研究的機(jī)器人運動學(xué)分析結(jié)果進(jìn)行驗證,結(jié)果基本一致,為機(jī)器人的后續(xù)研究,如動力學(xué),控制等奠定基礎(chǔ)。
With the development of computer and network ability , people ' s requirement for computing velocity , reliability of system and actual effect of cost must extremely stimulates the interesting in distributed parallel computing system . distributed system can be used at a lot of fields now and could be used everywhere in the future 隨著計算機(jī)的迅猛發(fā)展與網(wǎng)絡(luò)性能的不斷提高,未來人們對計算速度、系統(tǒng)可靠性和成本實效性的要求必將極大地刺激人們對分布式并行計算系統(tǒng)的興趣,分布式系統(tǒng)在許多領(lǐng)域已經(jīng)得到重要的應(yīng)用。
