  1. The control of beam halo - chaos becomes a critical problem in the development of high intensity accelerator. efforts to remove the halo by collimation have been largely unsuccessful since the halos almost always regenerate. the mechanisms of halos are complex, such as nonlinear resonances and chaotic behavior etc. considering this, professor fang jin - qing who works in china institute of atomic energy pointed out that the theory of chaos control can be used to control beam halos. he presented the method to control halos by using nonlinear functions, which means nonlinear function g is added to the right of ion radial self - edlctric force equation and some nonlinear function are selected to control beam halos in simulations. in paper [ 69 ], controllerg = - 0. 15sin ( rmax - am ) 2 was used and the halo intensity was decreased to 0. 1078, the halos are removed partly

    束暈?混沌的控制是新一代強流加速器研製的關鍵問題，隨著強流離子束應用前景的日趨廣闊而日益成為研究的熱點。傳統機械限束器因無法解決束暈的再生而收效甚微，因為束暈的形成有著其內在動力學機制?非線性共振以及混沌等。基於此，中國原子能科學院研究員方錦清將混沌控制的理論和方法開創性的運用於束暈?混沌的控制上，提出了控制束暈?混沌的非線性控制策略，即在粒子徑向所受束自生場力方程的右邊加上非線性控制函數g ：並選取一些非線性函數如等進行了控制的模擬研究，將束暈強度控制在0 . 1078左右，取得了初步的控制效果。
  2. However, this approach is faced with two key challenges. first is the keen competition from fast emerging ports in southern china, in particular the prd region, which has been assessed in the latest round of the study on port cargo forecasts. one of the conclusions of the study was that although neighbouring ports offer lower monetary costs, ours has the advantages in terms of high frequency of callings, extremely efficient operation and associated logistics services

    首先是華南一帶的港口，近年冒升之勢甚速，儼然成為香港的強大競爭對手，其中尤以珠江三角洲的港口為甚；我們已透過最新的港口貨運量預測研究，分析這趨勢對我們的影響；研究結論指出，雖然珠江三角洲港口收費低廉，但香港卻在頻密的船期，作業迅速有效，以及物流增值服務上，較鄰近港口優勝。
  3. The surface panel method has been applied to predict the hydrodynamic performance of highly skewed propeller. the surface of propeller and its trailing vortex are discreted by a number of small hyperboloidal quadrilateral panels with constant source and doublet distribution. for highly skewed propeller, the conventional method generating grid oriented along constant radii will result in a high aspect ratio and a high skewness and a twist panel near the propeller tip on blade surface, which result easily in incorrect calculation results of velovity on blade surface, even in iteration divergence and calculation failure. a “ non - conventional grid ” is developed to acoid these problems. this grid can effectively solve the problem of the calculation and convergence for highly skewed propeller. the non - linear kutta condition of equal pressure on upper and lower at the trailing edge is executed by the iterative procedure. by sample calculating, the obtained results are satisfied the experimental data

    採用面元法預報大側斜螺旋槳水動力性能，螺旋槳表面及尾渦面離散為四邊形雙曲面元，每個面元上布置等強度源匯和偶極子分佈.對于大側斜螺旋槳而言，槳葉表面採用常規的等半徑網格劃分方法在近葉梢處將導致大展弦比、大側斜和扭曲面元，這容易使槳葉表面速度的計算結果不正確，甚至會導致迭代過程發散及計算失敗.文中建立了一種「非常規網格」劃分方法，能有效地解決大側斜螺旋槳的計算和收斂問題.槳葉隨邊處通過迭代實現非線性等壓庫塔條件
  4. That was the year in which china began trying, with limited success, to put on the brakes

    正是2004年起，中國開始放緩經濟增長速度，但收效甚微。
  5. The governor has tried to hold the lagging company ' s feet to the fire, but to little effect

    政府試圖讓慢吞吞的公司迅速行動起來，但是收效甚微。
