When the dosage was 8 % aa , the effect was best . ( 2 ) the performance of pc was decided with the proportion of pea , aa , mma . the fluidity of copolymer would augment if the dosage of aa increase , but when dosage of aa was 75 % , it was hard to control the compose reaction , and dispersion of pc would depress ; when pea degree of polymerization augment the air - entraining of mma would increase ; it would produce floe and hard to control the compose reaction when the dosage of pea4 more than 15 % , pea23 more than 25 % ( 2 ) pea 、 aa 、 mma之間的比例關系決定了共聚體的性能:隨著丙烯酸用量的增加,共聚體的流動度增大,達到75時合成控制難度加大,共聚體分散性下降;而mma的引氣增穩作用,其用量隨著pea的聚合度的增加而增加, pea4體系的用量超過15 , pea23體系超過25則會產生絮狀物,反應控制難度加大,理想的用量分別為不超過10和15 。

The microscope studies on the dynamics and kinetics of primmorph formation suggest a tentative mechanism that primmorphs are formed through four stages : amorphous large cell floe , small irregular cell aggregations , large primary cell aggregations and round - shaped primmorphs 以地中海寄居蟹皮海綿( suberitesdomuncula )為研究對象,研究了mcp - primmorph培養中的營養需求,生長和增殖規律,代謝特點等基本特征。

It was observed respectively by optical microscope and sem ( scanning electron microscope ) that bacteria , filamentous fungi , protozoan and metazoan were adhered on the surface of the sludge , and the microorganism of the floe in the forms of micro - colones 光學顯微鏡和掃描電子顯微鏡觀察發現,污泥表面附著有各種球菌、桿菌、絲狀菌以及原、后生動物,凝絮體中微生物以微群落形式分布。

Up to 20 percent of the atlantic herd usually nests on thick ice floes in the southern gulf region in february or march . but this year authorities and animal rights groups found only slush and ice fragments too small to support a newborn pup 在那些生活于大西洋水域的海豹群體里,選擇在圣勞倫斯海灣地區的大塊厚浮冰上筑窩產崽者所占的比例高達20 。

On the edge of the arctic ocean at point barrow , alaska , several fur - clad eskimos gaze intently at a narrow area of blue water between the ice floes where a great creature of the sea comes closer and closer 在阿拉斯加巴婁岬角附近的北冰洋邊上,幾個愛斯基摩人正在緊盯著浮冰之間的一片狹窄的藍色水面,那里有一個巨大的海洋動物在向他們一點點游來。

In this way thick and big floes are formed . this process decides that floes have self - similarity and dilation symmetry in a certain extent , and they are two important characteristics of the fractal 這一過程決定了絮凝體在一定范圍內具有自相似性和標度不變性,這正是分形的兩個重要特征。
