The invention also provides a nonwoven cloth of drawn long fiber provided with a first web layer of crimped filaments, and a second web layer of substantially non-crimped, drawn long fiber filaments, and comprising different kinds of polymers of high strength and bulkiness, and a method of ...
aPolymers can be classified in several different ways:according to their structures,the types of reactions by which they are prepared, their physical properties,or their technological uses. 聚合物可以被分类用几别的方法:根据他们的结构、他们准备反应的种类,他们的有形资产,或者他们的技术用途。[translate...
aproteins also occur in great variety;thousands of different kinds,ranging in size from relatively small peptides to huge polymers with molecular weights in the million,may be found in a single cell. 蛋白质在巨大品种也发生; 数以万计不同的种类,排列在大小从相对地小肽到巨大的聚合物以分子量在百...
根据“One of the bacteria is called synthetic cyanobacteria (合成蓝藻), which can use sunlight to produce sugar.”可知,应该利用阳光产生糖;根据“ It eats the sugar that the first bacteria produce and then it can produce polymers (聚合物).”可知,然后细菌开始吃糖,并产生聚合物;根据“Polymers are...
The other kind is Halomonas Boliviensis(利维亚盐单胞菌), which lives in the salty waters of Bolivia. It eats the sugar that the first bacterium produces and then it can produce polymers(聚合物). Polymers are used to create bio-plastics. The way the bacteria store polymers is similar as ...
The different shear levels were imposed on three kinds of polymers, isotactic polypropylene, polystyrene, and polyurethane, that have different properties. In contrast to the dies with diameters of 0.5, 0.7, and 1mm, with the increasing shear rate the growth of the logarithmic shear stress ...
aI enjoy reading different kinds of books, but "Harry Porter" is my favorite one. The story is very long but I am interested in it. Harry was such a brave and clever boy that he dared to fight against powerful enemies. His Z-shaped scar and magic stick brought me into a magical ...
aProteins are polymers constructed from the same set of 20 different amino acids. The primary structure sequence of amino acids is specified by the gene. In the secondary structure, portions of protein begin to coil fold unique three-dimensional formation. Two kinds of secondary structure units ...
