  2. Abstract : a new clock - driven eco placement algorithm is presented for standard - cell layout design based on the table - lookup delay model. it considers useful clock skew information in the placement stage. it also modifies the positions of cells locally to make better preparation for the clock routing. experimental results show that with little influence to other circuit performance, the algorithm can improve permissible skew range distribution evidently

    文摘:提出了一種新的時鐘性能驅動的增量式布局演算法，它針對目前工業界較為流行的標準單元布局，應用查找表模型來計算延遲.由於在布局階段較早地考慮到時鐘信息，可以通過調整單元位置，更有利於后續的有用偏差時鐘布線和偏差優化問題.來自於工業界的測試用例結果表明，該演算法可以有效地改善合理偏差范圍的分佈，而對電路的其它性能影響很小

  4. The paper has improved the existing lifting - line and lifting - surface design method by including the rake and skew and solving the optimum circulation distribution with the optimum theory. the blade geometry is expressed with b - spline for the lift - surface method. the boundary condition on the blade is transformed to minimize the summation of the square of normal velocities, the fair blade geometry can be obtained by present technique and the design quality is better

    改進了現有的升力線和升力面設計方法，在升力線設計中計及槳葉的縱傾和側斜的影響，用優化理論求解最佳環量分佈，升力面設計中用b樣條來擬合槳葉，將物面邊界條件轉化為求法向速度分量的平方最小，由此可得到光順的槳葉幾何形狀，提高和改進了設計質量。
  5. The knowledge on the properties of used materials is urgently needed for reasonable life - prediction and life - distribution. as cylinder bolts are concerned, they often rapture at the first tooth - root resulting from lower high temperature strength of their material and higher stress. since bolts operate at high temperature environment, creep skew and damage causing their failure are important factors that can not been neglected

    就汽缸螺栓而言，由於螺栓材料的高溫強度偏低，預緊力過大，常常在螺栓的第一齒根部位發生蠕變脆性斷裂，因其長期在高溫環境下工作，蠕變變形和蠕變損傷是其失效的一個不可忽略的重要因素。
  6. Second, the bar of the frequency - distribution and the curve of lorenz and the g coefficient are talked about the spatial distribution of day to day precipitation. the results show that the heterogeneous of day precipitation is strong on every day in a year. the spatial distribution model is left skew all in four seasons and it is different from the monthly precipitation

    其次利用全國700個測站逐日降水資料的空間分佈頻數直方圖及洛倫茲曲線和基尼系數闡述了我國逐日（ 24小時）降水非均勻性的事實，直方圖顯示全國范圍內逐日降水的水平空間分佈型在四季都是一種明顯左偏態型，與月降水量的水平空間分佈型略有不同；基尼系數值的月際變化也與月降水量的變化相反。
  7. Displacement method in structural mechanics and generalized grillage analogy method are combined to analyze skew support continuous curved t girder bridge, when calculating inner forces of a single curved beam, calculate its deformation, then at the base of basic principle of generalized grillage analogy, derivates calculating equations of load lateral distribution and inner forces of skew support continuous curved t girder bridge

    對斜支承連續曲線t梁橋進行分析時，採用結構力學的位移法與廣義梁格法相結合，在求解單根曲線梁內力的同時，求得其變形，在此基礎上利用廣義梁格法基本原理，進行荷載橫向分佈及內力計算，推導出斜支承連續曲線t梁橋的內力與荷載橫向分佈計算公式。
  8. The soil as of the study area was positive skew distribution, tally with second steps stable supposed, after gaussian non - liner change

    結果表明，研究區土壤砷為正偏態分佈，經高斯非線性轉化后，符合二階平穩假設。
  9. By comparing and analyzing the measured water level, three - dimensional velocity distribution and turbulent character around the bridge location, the calculation method for the backwater of skew bridges is improved and the reduction factor of block water width is presented

    通過對橋位附近的實測水位與水流三維流速分佈及紊動特性的比較分析，改進了計算斜交橋壅水的方法，並給出阻水寬度折算系數。
  10. In the paper, the main results are brought forth in five aspects as follows : ( 1 ). the analysis of statistics the characteristic indicated that the variation coefficient of the soil nitrogen density of 0 ~ 30cm depth is lower, the variation coefficient is only 3. 6 %, the variation coefficient of the nitrogen density of 0 ~ 100cm depth is much bigger than that the 0 ~ 30cm depth, it is 100 %. based on the second national soil general survey material, the average soil profile depth is 101cm, this is in corresponding with skew normal distribution, its standard deviation is 0. 0192
