  • 數 : 數副詞（屢次） frequently; repeatedly
  1. A bearing surface transmits the interaction between an arch dam and its foundation, the strength of which directly affects the constraint of the bedrock to the dam, and thus affects the stress and deformation of the dam. the influence is studied in this paper with nonlinear finite element method, as an example, for a high arch dam in design. the results show that the influence on stress is only limited within the local area near the bearing surface, larger on the maximum principal tensile stress than on the principal compression stress, and the decrease of the strength does not cause unlimited increase of the maximum stress. the influence on the displacement of the top of the dam is smaller than that of the bottom of the dam, especially the relative downstream displacement. at the lower strength of the bearing surface, the relative downstream displacement at the bottom of the dam increases with the decrease of the strength

    建基面是傳遞拱壩和基巖相互作用的紐帶，它的強度直接影響基巖對壩體的約束，從而影響壩體的應力和變形.採用非線性有限單元法，以設計中的某高拱壩為例，分析建基面強度對壩體應力和變形的影響.結果表明建基面強度對壩體應力的影響僅限於建基面附近的局部范圍，對最大主拉應力的影響要大於對最大主壓應力的影響，建基面強度的降低不會無限地增大壩體的應力數值；建基面強度對壩頂位移的影響較小，但對壩底位移（尤其是順河向相對位移）的影響較大，當建基面強度較低時，壩底順河向相對位移隨建基面強度的降低而增大
  2. In the flight experiment of aircraft, the mass data acquisition, storage and transfer is always one important part of system, especially for the measurement of parameters such as temperature and pressure of cockpit. in order to meet these needs, we design this simultaneous data acquisition system with multi - channel and large - capacity, which is based on single chip microprocessor and usb interface. it overcomes some shortcomings of traditional devices such as : big size, short work time, small memory capacity etc. it also has many advantages of high speed, low power dissipation, ease - of - use, ease to expand port, supporting plug - play, low - cost etc, so it will be used very widely

    在飛機的飛行試驗中，海量數據的採集、存儲和傳輸一直是系統非常重要的一部分，尤其是對飛行員駕駛艙環境控制系統的溫度、壓力等參數的測量來說更是如此。本文根據課題實際需要，研製的基於單片機和usb介面的多通道、大容量、便攜式數據採集系統，克服了現有設備體積大、工作時間短、存儲容量小等缺點。同時，本系統還具有功耗低、速度快、使用方便靈活、易於擴展、支持即插即用、成本低廉等一系列優點，具有廣泛的應用前景。
  3. By this time, the rate of single handwritten character recognition, especially figure recognition, has reached 95 %. but to the sequential characters, or mathematic character recognition there is not a perfect product

    到現在，單字元手寫體識別，尤其是數字識別率接近95 ，但對于連續的字元書寫，尤其是有數學符號的情況下，由於聯機手寫的隨意性比較大，寫作不規范，還沒有一個成熟的產品。
  4. Genetic algorithm is a searching algorithm that simulates biology evolvement in nature. because of its briefness, strong robustness, especially it need not expert domain knowledge but fitness function as the value guide searching process, its applications are very abroad

    遺傳演算法是一種模擬自然界生物進化的搜索演算法，由於它的簡單易行、魯棒性強、尤其是其不需要專門的領域知識而僅用適應度函數作評價來指導搜索過程，從而使它的應用極為廣泛。
  5. But the standard mc has some shortcomings : firstly, the standard mc picks up isosurfaces by threshold, however, threshold segmentation is invalid for picking up tissues or organs from some medical images ; secondly, the standard mc pocesses cubes one by one, that is to say, all the cubes will be checked, and the algorithm spents 30 % - 70 % of time to check the null units, so we need a reasonable data structure to travel the space data and accelerate the checking or filting of null units ; thirdly, the standard mc has a large scale of triangles, normally, the tissue or organ reconstructed includes hundreds of thousands so much as millions of triangles, this means it hardly to execute real - time rendering or interaction ; lastly, the standard mc can not get the very smoothly surface mesh, and there will be some unexpected accidented cases, especially in the case of big errors in oringinal data

    但是標準mc演算法存在較大的問題:標準mc演算法實質上是通過閾值分割來提取等值面，閾值分割對某些醫學圖像的組織或器官的提取難以得到較好的效果;標準mc演算法是逐個移動立方體來進行處理，就是說對所有的立方體都要進行一次檢測，演算法執行中30 % ~ 70 %的時間用在對空單元的檢測上，因此需要有一種合理的數據結構對空間數據進行有效的遍歷，以加速對空單元的檢測和過濾;標準mc演算法產生了大量的三角面片，一般重建的組織或器官包含數十萬甚至上百萬的三角面片，難以實現實時的繪制和交互操作;標準mc演算法得到的表面網格並不光滑，會有一些不期望的凹凸，特別是在原始數據有較大誤差的情況下尤其突出。
  6. Traditional technique of database was centered by single data resources ( database ) to all kinds of data management including dealing with affairs, batch and decision - analyses. although database made great success in the application of dealing with affairs, the support of analysis and management has been unsatisfactory, especially, when the application of oltp which mainly deal with affairs and the application of dds which mainly deal with analysis are in the same system of database, the two kinds of managements have an obvious conflict

    傳統的數據庫技術以單一的數據資源，即數據庫為中心，進行從事務處理、批處理到決策分析等各種類型的數據處理工作，盡管數據庫在事務處理方面的應用獲得了大的成功，但它對分析處理的支持一直不能令人滿意，尤其是當以業務處理為主的聯機事務處理（ oltp ）應用與以分析處理為主的決策支持系統（ dss ）應用共存於同一個數據庫系統時，兩種類型的處理發生了明顯的沖突。
