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。
The dissertation studied the control velocity of the micro robot . chapter six discussed the control with the demands of safety and human comfort when the micro 論文第六章針對機器人運行的平穩(wěn)性和人體的舒適性要求,提出了機器人的阻抗擰制方案。
Because of the nonlinear , time - variability and uncertainty of the submerged - arc welding progress , the characteristic of accurate mathematic model being hard to establish , we can adopt the fuzzy control technology to design the welding dolly control system , and the couple closed - loop fuzzy control velocity system and fuzzy control algorithm for the speed of the welding dolly are researched based on the control system of submerged ? arc welding 同時長時間工作也容易使人產(chǎn)生疲勞,影響焊接質(zhì)量。針對埋弧焊過程的非線性、時變性和不確定性,難以建立精確的數(shù)學(xué)模型等特點,采用模糊控制來設(shè)計焊接小車控制系統(tǒng),同時研究了焊接小車雙閉環(huán)模糊調(diào)速系統(tǒng),并針對焊接小車速度的雙閉環(huán)模糊控制算法進行討論。
