接枝者 的英文怎麼說
中文拼音 [jiēzhīzhě]
接枝者
英文
grafter-
Consequently, with increasing mmt content, the tensile strength and young ' s modulus of hdpe - g - aa / mmt nanocomposites increased, while that of hdpe / mmt composites decreased. moreover, the addition of mmt to hdpe - g - aa decreased the melting temperature and the degree of crystallization of the matrix. these changes may be attributed to high interfacial adhesion between hdpe - g - aa matrix and exfoliated clay, which reduces the mobility of crystallizable pe chain segments, and subsequently reduces the crystallization ability
研究結果表明： mmt在hdpe中不能達到納米級分散，而在hdpe - g - aa中， mmt能以插層型利剝離型的結構存在，這主要是由於極性的丙烯酸接枝在hdpe上提高了後者的極性，而且能與mmt上的活性基團進行化學反應，從而提高了pe鏈進入mmt層間的可能性，使mmt在基體中達到納米級分散。As to the high - density polyethylene, two strategies were performed : ( 1 ) after being modified by grafting polar groups on its backbone, polyethylene and organic montmorillonite were melt mixed directly, which could obtain the polyethylene / montmorillonite nanocomposites. the effect of groups grafted on the backbone on the efficiency of intercalation was investigated in this paper ; ( 2 ) choosing the grafters obtained in this experiment as the compatilizers, polyethylene / montmorillonite nanocomposites had also been prepared by melt mixing the polyethylene, grafter and organic montmorillonite. the difference of grafters and sequence of mixing on the intercalation result had also been analyzed
對于高密度聚乙烯，採用以下兩種思路進行： （ 1 ）對聚乙烯首先進行功能化改性，使聚乙烯分子鏈上接枝上不同的極性基團，將改性后的聚乙烯再同有機蒙脫土直接熔融復合，成功的制備了聚乙烯蒙脫土納米復合材料，並考察了接枝到聚乙烯主鏈上基團的不同對最終插層效果的影響； （ 2 ）選用制得的接枝物作為相容劑，將聚乙烯，接枝物，有機蒙脫土三者熔融復合，也可以得到聚乙烯蒙脫土納米復合材料，並對選用不同的接枝物作為相容劑以及復合順序對最終插層效果的影響加以分析。As soon as growers learned to bud or graft, they chose as scion sources the trees that were superior for their area.
種植者一旦知道了枝接或芽接，他們就把當地的優良植株選來作接穗材料。Preparation, structure and properties of hdpe ~ g ~ aa / mmt nanocomposites melt grafting reaction of hdpe with aa was performed in thermohaake rheomix and hdpe - g - aa with high grafting degree and high grafting efficiency was prepared. the change of torque indicated that the graft copolymerization was existed during melt compounding. the extent of grafting was analyzed by ftir and element analysis
在hdpe中只加過氧化二異丙苯（ dcp ）時，由於發生交聯反應而使平衡扭矩明顯增加，熔點和結晶度降低，加入aa后， aa與hdpe的接枝和hdpe自身的交聯並存，前者對後者有抑制作用，從而使扭矩下降，熔點和結晶度部分恢復。For the preparation to illustrating this children s book, as the illustrator, i received lots of materials about sharks from the author, twig and the editor, amy
為準備為這本兒童圖書作插圖，比如以圖例解釋者，我接受了許多材料關于鯊魚從作者枝杈和編輯，艾米。Avrami exponent did n ' t change obviously after grafting, which indicated that the crystallization mechanism of pp - g - am was almost as same as pp
Pp接枝前後avrami指數n無明顯改變，表明兩者結晶機理基本相同。And when the suitors broke down her temple gates to get near their beloved rhodanthe, she became angry turning rhodanthe into a rose and her suitors into thor
當求婚者沖進了神廟的大門，要接近他們所愛戀著的羅丹斯時，黛安娜一怒之下將羅丹斯變成了一枝玫瑰花，將她的求婚者變成了花刺。And when the suitors broke down her temple gates to get near their beloved rhodanthe, she became angry turning rhodanthe into a rose and her suitors into thorns
當求婚者沖進了神廟的大門，要接近他們所愛戀著的羅丹斯時，黛安娜一怒之下將羅丹斯變成了一枝玫瑰花，將她的求婚者變成了花刺。The cloven halves were not broken from each other, for the firm base and strong roots kept them unsundered below ; though community of vitality was destroyed - the sap could flow no more : their great boughs on each side were dead, and next winter s tempests would be sure to fell one or both to earth : as yet, however, they might be said to form one tree - a ruin, but an entire ruin
但裂開的兩半並沒有完全脫開，因為堅實的樹基和強壯的樹根使底部仍然連接著。盡管生命的整體遭到了破壞一樹汁已不再流動，每一片大樹枝都已枯死，明年冬天的暴風雨一定會把裂開的一片或者兩片都刮到地上，但是它們可以說合起來是一棵樹一雖已倒地，卻完整無缺。In attempt to prepare and study the novel electrically conductive nanocomposites, with polyethylene ( pe ) served as the matrix, maleic anhydride grafted polyethylene ( gpe ) served as eg intercalates and expanded graphite ( eg ) served as a conductive filler, prepared gpe / eg, pe / gpe / eg electrically conductive composites via solution intercalation ( si ), direct melt mixing ( dmm ) and master batch melt mixing ( mmm ) methods. by means of testing conductivity and mechanical property, with the measures of tem, sem, om, xrd and dsc, studied the relationship between preparation method, material composition, and electrically conductive as well as mechanical property. the main outcomes never reported at home and abroad literature were obtained as follows : 1 the gpe / eg electrically conductive nanocomposites were prepared via si method
