  1. Because of the lower rock fragmentation efficiency and defective geometrical shape of chisel bit, sweden has replaced chisel bit with taper connecting cross chisel bit and button bit since the mid - seventies

    因一字形釬頭破巖效率低和幾何形狀結構缺陷等問題，瑞典從70年代中期就用錐體連接的十字和球齒釬頭取代了一字形釬頭。
  2. Obtained numerical simulation results of flow fields include the resistance and efficiency performance, with the geometrical boundary completely according with the actual one and nothing being simplified. 2

  3. Unlike traditional differential geometrical method, the robust adaptive neural net - based control emphasizes on the theory and application of intelligence control in nonlinear system that is weighed by robust performance index. the problem of robust reliability and stability in a kind of weak nonlinear system is first proposed in the dissertation, and then it deeply analyses and discusses the problem of how to design track controller in strong nonlinear system with uncertainties and external disturbance on the premise of guaranteeing the whole system ' s robust performance index. the distributed 3d flight simulation platform is mainly used to validate real - time program and evaluate the efficiency of advanced flight control laws, therefore, some theories and techniques related to the platform are also introduced

    基於神經網路的魯棒自適應控制研究和分散式三維飛行模擬平臺的構建是本論文研究的兩個主要內容，與傳統微分幾何方法不同的是，基於神經網路的魯棒自適應控制側重於智能控制方法在以魯棒性為性能指標的非線性系統中的理論和應用研究，論文以一類弱非線性系統的魯棒可靠鎮定問題為引線，逐步深入地分析和探討了在保證整個被控系統魯棒性能指標的前提下，對于幾類具有不確定性和外部擾動的強非線性系統跟蹤控制器的設計問題；分散式三維飛行模擬平臺主要用於先進飛行控制律的實時程序驗證和效能評估之用，因此關于平臺的一些開發原理和技術方法也在文中給出了介紹。
  4. The turns in the serpentine channel were asymmetrically tapered to minimize geometrical contributions to band broadening and to provide ample channel length for high - efficiency chromatographic separations

    蜿蜒通道地轉彎處是不均勻地錐形以減小幾何原因引起地譜帶展寬和提供樣品通道長度使高效色譜分離。
  5. Which is simple with high efficiency, and has the ability of anti - geometrical distortion while robust to some image processing such as filtering and smoothing, etc. to some extent

    其特點是計算簡單，精確度高，具有抗幾何畸變性，對濾波、平滑、壓縮等圖像操作有一定的魯棒性。
