There are three difficulties and key problems in this papaer : : the first problem is what is the dominance bearing of the leakage fractures, and how the bedrock fracture water distribute, the second is how to test the complex chemical behavior in experiment way and quantify the relative parameters, the last question is how to number the transportation of the element 90sr and its pollution to solve the three problems, this paper does lots of work and come to the prospective order, the creativities in this thesis as follow : ( 1 ) the dominance bearing of the leakage fractures and the distribution feature of the fracture water are ascertained based on rich geological data, these basal researches are very important, which are the premises to build the transport model of the fracture water in hae field
本項研究工作的難點和關鍵問題有三個： hae處置場基巖裂隙系統中，導水裂隙的優勢方位是什麼，基巖裂隙水活躍帶分佈情況如何；怎麼對核素遷移的復雜化學行為進行實驗室測試並取得有關定量化參數；怎樣數值化表現出溶質的遷移行為和污染情況本論文在解決以上三個問題上做了大量的工作，達到了預期的目的，其創新之處有以下三點： （ 1 ）通過地質資料的分析，首次提出了hae預選處置場基巖裂隙導水的優勢方位和基巖裂隙水活躍帶的大致分佈特徵。它是一個很重要的基礎性研究成果，是建立hae處置場水運動模型的前提。 -
In the design optimization of space equipment satellite systems, there are lots of discrete and integer design variables, the design space is nonconvex and even disjointed, and has multimodality. unfortunately, current mdo procedures or strategies have difficulty to deal with discrete or integer design variables, they are very sensitive to complex design space, have propensity to converge to local optima near the starting point, and can not handle multiple objectives effectively. to overcome these difficulties, this dissertation adopt the idea of coevolution to systematically develop new multidisciplinary design optimization methods based on decomposition and coordination
論文以航天裝備體系及其它復雜飛行器系統的多學科設計優化（ multidisciplinarydesignoptimization ，簡稱mdo ）為應用背景，針對航天裝備衛星系統設計中存在大量離散和整數設計變量、設計空間非凸和不連通、具有多個局部最優點等特點和現有mdo方法過程難以處理離散和整數變量、對復雜設計空間非常敏感、易於陷入局部最優、不能有效處理多目標等缺陷，採用協同進化的思想，系統地進行基於分解協調的mdo方法研究。 -
The long distance, the complex and variable landform along the pipeline, the large investment in the compensation for going through river, road and railway and also along the line there are lots of uncertain factors, all these add difficulties to the investment control of the gas transmission pipeline project
長輸管道項目通常線路長、路途地況復雜多變、 「三穿」及沿途補償投資額大且不確定因素多，投資控制和管理難度大，科學的投資控制和管理顯得尤為重要。本文將結合天然氣長輸管道類項目特點，結合實際項目，對工程設計階段、施工階段的投資控制進行研究。 -

For some autologous features of oral english classes, there are lots of difficulties in teaching
但口語課程由於其自身的特點，在教學中有許多困難。 -
The chief reason of the development of the case - based reasoning is that there are lots of difficulties to obtain knowledge in the traditional rule - based reasoning and that cbr systems don " t remember the solved problems, which result in low efficiency of reasoning, disability to deal with abnormal things and the rather friability of the system ability
Cbr興起的主要原因是傳統的基於規則的系統在知識獲取問題上存在困難，對于處理過的問題沒有記憶，導致推理效率低下、不能處理事例的例外情況，整體性能較為脆弱，而cbr恰好能夠解決以上問題。
