The fouling of monomer recovery system of qilu esbr plant was studied. it was con sidered that the fouling was principally caused b y the following four reasons, there existed the colopholic potassium containing c onjugated doublebonds in the disproportionated colopholic potassium, excessive co ntent of c16 - 18 compositions existed in the fatty acid, excessive content of com positions for which the demol condensation degree was above 5, the reaction conve rsion was higher than 72 percent. effective countermeasures were proposed
介紹了齊魯引進乳聚丁苯橡膠裝置回收單元存在的設備堵掛問題，經分析認為歧化松香酸鉀中帶有含共軛雙鍵的松香酸鉀，脂肪酸中c16 18組分含量高， demol縮合度高於5的組分高，反應轉化率高於72 %是造成堵掛的4條主要原因，提出了對策。For bilateral symmetry objects, the techniques on symmetry - point detection and symmetry - axis extraction are presented based on harmonic conjugation relationship. for rotated symmetry objects, the techniques on rotated units description and rotated symmetry center extraction are presented based on center invariants of objects. further more, by using 3d invariants and 2d projective transformation, an approach to recover shape from part symmetry objects is realized on some conditions
（ 3 ）深入分析了2d對稱性目標透視成像的幾何特點，將共點四線交比用於目標輪廓上的關鍵點的特性描述中；利用調和共軛關系，提出了一種針對左右對稱型目標的對稱點檢測和對稱軸提取的演算法；利用交比關系構造了目標的形心不變量，提出了一種針對旋轉對稱型目標的旋轉對稱單元判定、旋轉中心提取的演算法；進一步利用3d不變量和2d射影變換，實現了一定條件下的對稱性目標的形狀恢復技術。In conjugate gradient optimization algorithm, the continuous and digital models of an imaging system are defined to explain image acquisition, the image registration algorithm and the conjugate gradient reconstruction algorithm are designed
在共軛梯度最優化迭代演算法中，對相機模型、圖像微位移和微旋轉角精確配準、共軛梯度重建等關鍵技術進行了研究。Therefore, it is useful to make further study on heightener of reflectivity and applying in laser system with narrow pulse - width less than 30ns and high repetition rate more than 100hz for space - communication and laser - detect
而對光纖相位共軛器而言，關鍵問題是如何突破sbs反射率低於60的瓶頸，並應用到重復頻率大於100hz 、脈沖窄於30ns的激光系統中獲得較高的穩定性和較好的相位共軛效果。分享友人
