  1. Eg. ravenstein, the british statistician, the ancestor who researches flow of population, has said that the move and flow of population signifies survival and progress, while quiescence signifies stagnation and depression

    最早研究人的流動的英國統計學家eg .列文斯坦（ ravenstein ）曾說過，人的遷移與流動意味著生存和進步，而靜止則意味著停滯和蕭條。
  2. These saddle points represent points of stagnation of the current flow.

    這些鞍點代表電流的駐點。
  3. In the pseudo - time region, high efficient lu - sgs scheme was used in time - marching. cases with uniform or non - uniform inlet stagnation pressure and with or without tip - gap flow were studied. computed results showed that complex structure vortex appeared and secondary flow occurred in the flow of cascade with tip - gap

    對進口總壓均勻或總壓周向虧損（模擬上游尾跡） 、葉尖無間隙或有間隙等三種不同情況的流場計算結果，進行對比分析發現，流場中廣泛存在流動分離、分離渦以及二次流，這是引發非定常擾動的根源。
  4. As an example of 3d program with high quality mesh, proper boundary & initial conditions and ingenious simulation strategy, numerical analysis of flow - fields in hylte nozzle and cavity of dfcl running on fuel system of ( nf3 + h2 + he ) / d2 and experimental stagnation parameters, has been performed using vibration - state - unbalance & rotation - state - balance model, and a detailed kinetic model including 111 one - way primary reactions expressing by finite rate equations between thirteen species. the coefficients of transportation used in the analysis are calculated by employing the formulas of molecular kinetics

    新建立的三維程序在高質量網格、合理的初邊值以及模擬方案基礎上，採用振動非平衡?轉動平衡模型和有限速率方程表達的111個單向基元反應的化學動力學模型，利用分子運動理論計算的輸運系數和工程實驗採用的滯止參數，對運轉（ nf _ 3 + h _ 2 + he ） d _ 2燃料體系的df激光器的hylte噴管和光腔進行了數值模擬分析。
  5. Flow noise scaling at the stagnation point of an axisymmetric body

    回轉體駐點處的流噪聲相似律
  6. Some typical tsp problems from tsplib were chosen to test the performance of pmaco. the results show that the stagnation problem has been greatly improved and that the search precision and speed have been enhanced. pmaco is also applied to flow - shop scheduling problems, and can get a satisfying rate of finding the global optima

    2 .從tsplib中選取幾個典型問題對pmaco進行了tsp問題上的性能測試，模擬實驗結果表明，該演算法不僅對解決蟻群演算法的停滯問題非常有效，而且提高了運算精度和速度;將pmaco用於求解flow - shop生產調度問題，選取兩個應用實例對其進行檢驗，優化結果均令人滿意。
