  1. ( 4 ) substitute the every precedence relation of precedence construction network with a procedure, and the lag of precedence relation is defined as duration of the procedure which is named as lag procedure. the lag procedure does not consume resource, and the duration is random or determined

    將施工搭接網路的每一搭接關系改用新增的工序相連，並將該搭接關系的時距定義為這新增工序的持續時間，把這一新工序稱為時距工序。
  2. Many approaches developed offer approximation solutions, including principle - based, such as purely syntactic ones, semantic and pragmatic ones, and statistics - based ones. in this paper, we put forward a modal to resolve anaphora ( including empty pronoun ) based on the characteristics of chinese. in this method, we apply some corresponding rules on the sentences after their patterns distinguished in the text, then analyze the semantic relation of the components of the sentence and form a corresponding semantic network, get rid of some candidates according to the co - constrain of the nodes in that network, put every component which refers to people into forward - looking centers, ordered by their semantic role, ascertain the hierarchy of sentences, analyze the transition types resulted by the scheme of different resolutions, finally, choice the most possible scheme of resolution according to the precedence of the types

    本文針對漢語的特點建立了一個包括零代詞在內的代詞消解模型:在語義結構文法思想的指導下，對文本中的句子模式識別后，採用相應的規則式，然後分析句中成分之間的表層語義條件並產生相應的語義網路，利用語義網路中結點間的相互約束對代詞的某些候選先行詞進行排除，並且把每句中指人的語言成分放到前向中心列表中，以它們所充當的語義成分為排序依據，確定句子的層次結構，最後依據中心理論分析每個候選先行詞對代詞的不同消解所造成的層次相鄰的句子之間的過渡類型，利用過渡類型的優先順序對代詞的候選先行詞進行擇優。
  3. After the lag procedure introduced, the precedence network is transferred into generalized pert network, and then the risk of construction schedule could be calculated with the mc method or the modified pert method

    引入時距工序后，將搭接網路轉化為廣義pert網路，然後用mc方法或用當量概率修正pert方法計算搭接施工網路進度風險。
  4. After analyzing the characteristic of the parallel processing system, some problems about design missile - carrying processing system are pointed out ; network in the parallel processing system has become bottleneck and affect the performance of system, so the processing efficiency is analyzed in a multiprocessor system based on cluster - bus and some rules in designing the network in the multiprocessor system are brought out ; genetic algorithm is used for scheduling in the multiprocessor system, and a scheduling algorithm is described to suit arbitrary number of tasks, unequal task processing time, arbitrary precedence relation among tasks and arbitrary number of parallel processor, so that the schedule length will be minimized ; finally, an atr algorithm is mapped to a ring multiprocessor system, and a block diagram using dsp device is constructed. in chapter 4, the study is performed on real - time system hardware realization of atr. tms320c80 is selected as the kernel processor in multiprocessor system

    為此，對一種由常用的dsp晶元組成的多處理器系統的處理器利用率進行了分析，提出了多處理器系統互連網路設計的基本原則；本章使用遺傳演算法作為實現多處理器調度的工具，提出了一種新的任務調度演算法，該演算法主要是為了解決在任務數任意、任務計算時間不相等、任務前趨關系任意、以及任務間存在通信和考慮任務存貯器要求的情況下，如何優化任務在各個處理器上的分配和執行順序，使得多處理器系統總的執行時間最小；最後對一個目標識別演算法進行了硬體實現優化分析，根據分析結果，將演算法映射到由dsp晶元組成的環形網路連接的處理器拓撲結構上，得到了多處理器系統的原理框圖。
