Because there are some problems in gamut mapping technology, such as : the cie l * a * b * is not a perceptually uniform color space, the knowledge of custom colors is not sufficient, and how to select the anchor point is very important, we propose some ideas to solve these problems
本文在分析現有色域匹配技術的基礎上，針對其採用的抽象顏色空間非完全均勻、缺乏對習慣色的研究、以及如何選擇最佳映射參考點等問題，提出了若干解決方法。Based on orthogonal experimental avenue, dmm is manufactured by local po, sa, and phosphorus slag flying ash, yellow slag and ect. and formulate optimum mixture program and production technology requirement ; on basis of jcj70 - 90, physical mechanics property is quizzed, adopting chemical analysis, xrd, sem and so on, discuss composition and structure. the researchable result is that mixture program of dmm : a3b2cl ( cement 403 m2 / kg, phosphorus slag357 m2 / kg, activated agent 2 % ), after the condition of c / s1 : 4, adopting ordinary portland cement
採用正交試樣方法，用本地生產的普通硅酸鹽水泥、硫鋁酸鹽水泥、磷渣、粉煤灰、黃砂等原料配製抗滲干拌砂漿，確定最佳的配料方案和生產技術要求；按jcj70 ? 90 《建築砂漿基本性能測試方法》測定砂漿的各項物理力學性能；運用化學分析、 x衍射儀、掃描電鏡等測試手段，檢測配製砂漿的組成和結構。It has many benefits due to its ultra - wideband nature which including the following : not sensitive to channel fading, low transmit power, extremely difficult to intercept, low complexity of transceiver structure, fine range resolution ( centimeter scale ) for location and so on this paper combines uwb technology and mobile ad hoc network technology, concerting the lasn project of national key laboratory of communication, researchs the baseband process cell of uwb communication transceivers on the base of arithmetic research and spot test
本文結合uwb技術和移動自組織網（ manet ，即mobileadhocnetwork ）技術，配合通信抗干擾技術國防重點實驗室uwb技術研究項目「 lasnproject 」的工作進展，在演算法研究和現場測試的基礎上，對uwb通信節點樣機的基帶處理單元進行設計研究。樣機結構包含三大模塊:天線、用分立器件形成的射頻電路、由fpga構建的基帶處理單元。Multimode interference ( mmi ) couplers based on the self - imaging effect are rapidly getting popular because of the advantage of low loss, compact size and large fabrication tolerance. the thesis studied the principle of the mmi coupler. the optical field distribution in the multimode wave - guide is modeled by eim and mode propagation analysis method ( mpa )
本文介紹了矩形多模干涉耦合器的基本原理，採用有效折射率方法和導模傳輸分析方法模擬了多模波導中的光場分佈，設計並模擬1 2 ， 1 4對稱干涉型光功率分配器、 2 2配對干涉型光功率分配器，得到了比較均衡的功率輸出。The power control algorithm used in present cdma conunwhcation standar ( for examle, is - 95a and cdma2000 ) is to allocate ophmal power vector for the user in the system sboply by the distance betwen the base station and the user under a predefined norm ( for example, the transmitted power of user or the signalto - interfrence ratio ( sir received by the base station suffice to some a nddrization norm ),
在現行cdma通信系統標準中（如is - 95a或cdma2000標準） ，採用的功率控制方法是在一定的標準下（如移動用戶發射功率或信干比在到達基站時滿足某一最低要求標準） ，根據移動臺到基站的遠近來為系統內用戶分配功率的。分享友人
