長鏈支化 的英文怎麼說
中文拼音 [zhǎngliànzhīhuà]
長鏈支化
英文
long chain branching-
The crystallization and melting behavior of mellocene - catalized branched and linear polyethylenes of low molecular weight was studied. it was found that the crystalline lattice of branched polyethylene is larger than that of linear polyethylene because of the existence of branched chains. the melting behavior of branched polyethylene is similar to that of linear polyethylene since the branched chains can not enter the lattice. however, the crystalline behavior of low molecular weight branched polyethylene is the same as that of high molecular weight linear polyethylene, but different with that of low molecular weigh linear polyethylene. kinetics theory analysis evidenced that the transition temperature of growth regime of the branched polyethylene is about 20 lower than that of linear polyethylene with the same molecular weight. it may be attributed to the existence of short branched chains
研究了金屬茂催化的低分子量支化聚乙烯和線性聚乙烯的結晶及熔融行為，發現支化聚乙烯的結構與線性聚乙烯相同為正交結構，但晶格略有膨脹.支鏈的存在對熔融行為影響不大，兩種聚乙烯的熔點均隨結晶溫度的升高而非線性增加，表現出低分子量樣品的共同特徵.但支鏈的存在對結晶行為卻有很大的影響，主要是由於支鏈的存在降低了晶體的結晶速率從而影響結晶過程，使得低分子量的支化聚乙烯的結晶行為與高分子量線性聚乙烯的結晶行為相似而與低分子量的線性聚乙烯不同.動力學分析表明，低分子量的支化聚乙烯的結晶生長方式的轉變溫度比同等分子量的線性聚乙烯降低了約20Being another innovation on the mode of rural management and the form of industry organization after the household output - linked contract responsibility system, the agricultural industrialization management is propitious to prolong the agricultural industry chain ; promote the qualifilization of agricultural product, the elaboratilization of agricultural processing and the regionalization of agricultural layout ; give full play to the regional resource advantage ; cultivate and develop the distinctive industry
農業產業化經營是繼家庭聯產承包責任制以後我國農村生產經營方式和產業組織形式的又一次創新，它有利於延長農業產業鏈，促進農產品生產優質化、農產品加工精細化、農業布局區域化，發揮各地區資源優勢，培育和發展特色產業。農業產業化經營離不開小城鎮的支持。Using v2 & 5 and alkylamines ( cs - cao alkyl chain ) as precursor, vanadium oxide nanotubes which have an unique structure that alkylamines intercalate into layers of tubes wall affecting the layer spacing were prepared. their layers spacing ranges from 1. 25 nm to 3. 82 nm according to the length of alkyl chain. moreover, the growth mechanism of vanadium oxide nanotubes have been investigated and 3 - 2 - id model was established to interpret the vanadium oxide nanotubes growth process. potassium niobate is a functional materials which can be used as photochemical catalysts. lt is well known that the catalytic activites are affected greatly by the surface area of catalyst particles on which the reaction take place
