Comparison of flow regimes is made for different reynolds - number flows and mesh refinement. the current study for the laminar flow over a backward - step facing step explores the influence of the sidewall on the development of three - dimensional flow for re > 400. meanwhile, this paper attempts to study on some important aspects of time - dependent incompressible viscous flow
本論文的主要研究成果有： 1 、評述了三維粘性流動數值模型的研究現狀，分析了各數學模型的建模思想及相應的數值計算方法，提出了當前存在的高精度的數值計算方法和邊界條件的適定性問題。 -
Based on tree data structure, the cartesian grids about 2 - d and 3 - d configurations are generated using the surface - cutting procedure. in the course of grid generation, a two - step ray - casting algorithm to excluded cells inside the body and a cell - merging technique to avoid numerical instability are fully developed. after creating these surrounding grids, the cell - cutting algorithm is designed to perform geometry - based refinement of grids, and greatly improve the applicability and quality of grid generation
採用物面切割，基於叉樹數據結構，發展了一種普遍適用於二維和三維外形的直角切割網格生成方法；構造兩步射線求交演算法，刪除外形內的固體網格，以及小網格合併演算法，確保網格質量和流場計算的穩定性；運用對任意網格的切割細分演算法，實現了針對幾何外形的自適應網格加密，使得網格生成更具普適性和靈活性。 -
Demands for spatial index directly come from spatial methods. in spatial database, spatial methods are implemented in two steps : first is filter step, in which spatial object ' s number is reduced through spatial index. second is refinement step, in which spatial objects resulted from filter step are subjected to exacted computation
空間索引的直接需求來自於大量空間對象上的空間運算，本文認為在空間數據庫中空間運算應該分兩步進行：第一步是篩選步驟，通過空間索引縮小進行比較的空間對象的個數；第二步為細化步驟，對從第一步中篩選出的空間對象進行精確的空間運算操作。 -
That is to add a special fluorescence - based dna internal standard in the telomerase elongated ts primers, then do pcr amplification after a step of refinement ( hydroxybenzene / chloroform extracting, and deposited by ethanol ). sequencing analysis of pcr product was done on 310 gene scan analysis ?. 1. 2 dna sequencer to determine telomerase activity. notably, this method eliminated the restraining factors of taq dna polymerase, making it possible to erase the sample differences met in pcr and eradicate the annoying phenomena of pseudo negative results
在kim等開發的端粒重復擴增分析法（ trap ）的基礎上進行改進，即通過對端粒酶延伸ts寡核昔酸反應產物的精製，消除了pcr擴增中抑制taq酶活性的因素，從而減少了樣品之間pcr擴增上的差異和假陰性現象的發生，提高了判斷樣品端粒酶陰、陽性的準確率和定量的準確性。 -
We take a step - wise refinement approach to the development of correct reconfigurable hardware circuits from formal specifications. a functional programming notation is used for specifying algorithms and for reasoning about them
建議的開發模型用功能記號來描述演算法以及對于演算法的推理，用程序編譯方案從功能描述導出大量的并行演算法。
