杠桿臂 的英文怎麼說
中文拼音 [gānggǎnbèi]
杠桿臂
英文
arm of lever-
The gradual development of these building blocks, following the invention of the roller or wheel and the arm or lever in ancient times, brought about the industrial revolution, starting with the assembly of james watt ' s engine for harnessing the force of steam and proceeding into the advanced mechanization of present automatic control
隨著遠古軋輥、輪子及臂狀物或杠桿的發明，這些構建塊逐漸發展起來，並帶來了工業革命並以詹姆斯?瓦特的以蒸汽為動力為開始，現在已進入到高級機械自動化的階段。Equal armed lever
等臂杠桿If your elbows and upper arms are not connected to your torso, the rein contact will enter your body at the shoulder level, which allows the horse to use the leverage of your torso against you, e. g. by rooting against the bit and pushing his croup up, which renders your seat and rein aids completely ineffective
如果騎手肘部和上臂不能和踝聯系，那麼韁聯系只能到你的肩膀，這樣馬就會利用你的踝的杠桿左右來對抗，馬匹對抗銜鐵，抬高尻部，從而導致你的騎坐和韁扶助完全失去效果。Combining the design of portal crane luffing mechanism, this paper set up the math model independently and synthetically of the single boom system with compensating pulley and level - balancing weight. use genetic algorithms to optimize the model, the calculated results show as follows the genetic algorithms is effective and manipulable, the synthetically optimize is best than independently optimize. the optimization program of luffing mechanism was build, and this will be a useful tool in the design of crane
結合門座起重機變幅機構的設計，建立了導向滑輪補償系統和杠桿? ?活對重臂架自重平衡系統獨立模型和綜合模型的未平衡力矩最小的優化問題，結合遺傳演算法對它進行了優化，結果證實了該演算法的有效性和可行性，表明了綜合優化比獨立優化更能提高優化的準確性。The optimization design of portal crane luffing system is the result that optimization design apply in engineering design, but because the engineering problem is complicated, the traditional optimization design method is not very successful. in this paper, the optimization of the single boom system with compensating pulley and level - balancing weight is studied. in the math model, the wire rope length encircled in the pulley and reel is considered, that enhance the optimization precision and introduce genetic algorithms, combine engineering tightly, that settle the difficult in the traditional optimization successfully
門機變幅系統優化設計是將優化設計方法應用於工程設計中的產物，但由於設計工程問題的復雜性，採用傳統的優化設計方法優化的成功率及效果並不理想。本文以單臂架變幅機構導向滑輪補償系統和杠桿? ?活對重臂架自重平衡系統的獨立模型及綜合模型為研究對象，考慮了滑輪和捲筒處包繞的鋼絲繩長度變化，從而提高了優化模型的精度，同時引進一種新型優化演算法? ?遺傳演算法，緊密結合工程實際，較為圓滿的解決優化過程中存在的問題。With its minimized structure, the path provides an optimal light - amplifying ratio ; ( iii ) the position sensitive detector ( psd ) is just located in front of the visual sight of operator, this makes the observation and operation more easily
該系統設計有特殊的光路，結構簡潔，體積小，通過多次反射提高反射臂的光程，保證了最佳的光杠桿放大比；同時，檢測系統中的位置敏感元件（ psd ）光敏面位於正對視線的方向，易於afm系統的操作和觀察。分享友人
