The linear block code is called a binary low - density parity - check code if it is based on a sparse parity - check matrix. this sort of code was originally proposed by dr. gallager in 1962, which cannot attract a large amount of interest at that time
低密度奇偶校驗（ ldpc ）碼是基於稀疏校驗矩陣的線性分組碼，它最初由gallager於1962年提出，當時並未受到人們的重視。 -
The impact behaviors of pp / eoc and pp / caco3 were compared. the toughening mechanisms of pp / eoc and pp / caco3 systems are firstly proved to agree well with wu ' s percolation theory. the essential condition occurring brittle - tough transition in two binary systems is that the matrix ligament thickness ( l ) is lower than the critical matrix ligament thickness ( lc ) which is approximate to 0. 095 ? m
比較ppffioc和ppcacos二體系的增韌行為，發現加入eoc和cacos都能增韌pp ，首次驗證了新型彈性體eoc和無機剛性粒子cacos增韌pp的機理符合wu氏逾滲理論，二體系發生脆韌轉變的基本條件是基體帶厚度l小於臨界基體帶厚度人（ 。 -

While flda only can get one optimal discriminating vector, by maximizing the fisher criterion, due to that the rank of the between - class scatter matrix is at most 1 for binary - class problem
但類間離散度矩陣的秩最大隻能為1 ，決定了flda只能取一個判別方向（最大特徵值對應的特徵向量） ，無法利用其它方向的判別信息。 -
The author uses the stabilization of parameter to combine the isolated images and process. with the help of matlab plat form, firstly we use binary image, rgb color space and yiq color space, gray co - occurrence matrix and shape analysis to deal with the images, then we use the stabilization of parameter to deal with the data. the result of recognition is good
作者首先採用rgb顏色空間處理法、 yiq顏色空間處理法、二值化圖像處理法、灰度共生矩陣處理法、形狀分析法對圖像進行處理，處理后所得到的數據再用參數穩定性處理法處理，這樣，就將圖像與與其所在過程結合起來，實踐證明，運用這樣的處理方法所得到的識別效果較好。 -
Fractal porous media can be simplified as a kind of binary mixture with different thermal conductivities. the calculated results show that heat transfer in fractal porous media is very complicated, the thermal coupling effect of matrix with pore structure is studied. when heat transfer in pore structure is neglected, the effective thermal conductivity for random sierpinski carpet is scaled up with the percent of matrix, which is described by the classic archie ' s law
本文首先採用有限容積法分析了分形多孔介質中的熱傳導過程，多孔介質可以視為二元混合介質，計算中發現分形結構中的導熱規律非常復雜，基質與孔隙之間存在著很強的相互換熱，當不考慮孔隙氣體中的導熱時，本文所構造的隨機sierpinski地毯上導熱系數與基質率（基質百分含量）大多呈指數關系，這與archie定律的結果是-致的。 -
From the mapping relationship between information vector matrix and relative vectors, rough approximation, attribute relative reductions and selecting optimal attribute reductions set algorithms based on binary vector matrix were proposed

Based on the svs characteristic analysis of image matrix, a visually recognizable binary image watermark is embedded into maximal singular value coefficient in block - based svd transform domain of the cover image. here we brought forward two primary schemes : one need original signal and the other is blind ( without the original cover ). experimental results show that our schemes can extract reliable copy of the hidden watermark from images that have been significantly degraded or altered through several common geometric distortions and signal processing operations
本文基於圖像矩陣的svd奇異值分解特性分析，提出了在新的svd變換域中進行的數字水印演算法，水印信息嵌入到分塊變換的最大奇異值分量系數中，應用混沌變換加密和空域置換，改善了空域性能，安全性高；利用圖像分塊矩陣的奇異值分解穩定性好的特點，採用圖像內容自適應方法計算水印的嵌入強度，增強了演算法的穩健性；採用二值圖像作為有意義水印進行嵌入和檢測，水印在感知上是可視的。
