国人 2022年8月合集 There are other areas of the body or certain situations where we want the stitches to dissolve and those dissolvable stitches or absorbable stitches are made out of either synthetic polymers or they're made out of animal intestines.
身体的其他部位或某些情况下,我们希望缝线溶解,这些可溶解的缝线或可吸收的缝线是由合成聚合物制成的,或者是由动物肠道制成的。
HbS carries oxygen perfectly well, but when it is deoxygenated, HbS changes its shape, which allows it to aggregate with other HbS proteins and form long polymers that distort the red blood cell into a crescent shape - a process called sickling.
HbS能够很好地携氧,但在脱氧时,HbS会改变其形状,从而使其与其它HbS蛋白聚集形成长链多聚体,进而使红细胞扭曲变形成新月型,该过程称为镰变。
That meant using renewables rather than fossil fuel; endeavouring to make carpet tiles out of carbohydrate polymers rather than petroleum; and recycling old-carpet sludge into pellets that could be used as backing.
这意味着公司将利用可再生能源,而不是化石燃料;并将努力用碳
化合物而不是石油制造小方地毯;而且还将重新利用旧地毯的沉淀物生产能够用于支持作用的小硬球。
It's unlikely to be the plastic itself: LEGO typically uses acrylonitrile butadiene styrene, or ABS, plastic—a highly durable polymer that keeps the pieces strong for building, or what LEGO calls " clutch power."
这不太可能是塑料本身的问题:乐高通常使用丙烯腈-丁二烯-苯乙烯(ABS)塑料,这是一种高度耐用的聚合物,能够保持积木的强度,并提供乐高所谓的“咬合力”。
