It's helpful to understand concepts like marginal analysis and elasticity.

理解析和这样概念很有帮助。

It has to do with substitutes and what economists call elasticity of demand.

这与替代品和经济学家所谓需求有关。

Golesworthy has Marfan syndrome, a genetic condition affecting the strength and elasticity of connective body tissues, including blood vessels.

高尔斯沃西患有马凡氏综合症，这是一种影响结缔组织（包括血管）强度和遗传病。

Photoaging from chronic sun exposure leads to a loss of elasticity in the skin, in other words, making it look saggy.

长期暴晒在阳光下会导致皮肤失去，或者说，使皮肤看上去下垂。

It's responsible for much of those muscles' elasticity and structural integrity.

它很大程度上决定了这些肌肉和结构整。

Now there's also elasticity of supply.

还有供给。

For the first time, we can have elastomers that are high elasticity or high dampening.

这是第一次，我们可以制作高或高阻尼系数体。

As a result, there are fewer functioning microfibrils in the extracellular matrix, and that means there’s less tissue integrity and elasticity.

这会导致细胞外基质中正常微纤丝减少，造成组织整和下降。

The cartilage gets softer, weaker, and continues to lose elasticity, and starts to flake off into the synovial space, called joint mice.

软骨变得柔软、脆弱，力持续降低，开始脱落，进入滑膜囊内，称为“关节鼠”。

At this point, it's typically combined with plastic fibers like spandex to increase the yarn's elasticity.

这时通常会混入氨纶之类塑料纤维，以提升纱线。

Neutrophils make an enzyme called neutrophil elastase, a protease capable of breaking down elastin, which is an extracellular matrix protein that gives elasticity and strength to lung tissues.

中粒细胞产生中粒细胞蛋白酶，该酶能够水解蛋白；蛋白是一种细胞外基质蛋白，赋予肺组织和韧。

Unfortunately, type I collagen doesn't interact with the proteoglycans in the same way and there is an overall decrease in elasticity in the cartilage matrix, allowing it to breakdown.

不幸是，一型胶原并不能和蛋白聚糖正常地相互作用，导致软骨基质整体减弱，容易解。

Without alpha-1 antitrypsin, the opposite happens - neutrophil elastase goes unchecked, and it damages the walls of the alveoli, and without that elastin, the alveoli loses its elasticity and structural integrity.

如果没有α-1抗胰蛋白酶，情况就会背道而驰：中粒细胞力蛋白酶不受抑制，将会损伤肺泡壁，没有了那层纤维，肺泡壁便失去和结构整。

During the process of wound healing, collagen is redeposited at the wound site, but instead of the basket-weave formation found in healthy tissue, the new ECM is aligned in a single direction, impeding inter-cell processes, and reducing durability and elasticity.

在愈合过程中，胶原蛋白会在伤口旁重新沉淀，但是不同于在健康组织中篮织形成法，新ECM以单向排列，这阻止了细胞间联系并且减少了耐久和伸展。

Finally nothing remains but the fibers, either gelatinous or made of horn, that constitute your household sponge, which takes on a russet hue and is used for various tasks depending on its degree of elasticity, permeability, or resistance to saturation.

刀用海绵是茶褐色，根据它力、渗透力或抵抗浸渍力程度大小，可以安排它作各种不同用途。
