查询词典 tensile

When ethanol goes into the red blood cells, osmotic pressure changing causes the cell vertices moving to the center, and double-concave disc surface will be the spherical one. It results in the red blood cell volume larger and surface area smaller, causes the ratio of the surface area and volume significantly decrease, and the resistance tensile capacity of red blood cells reduced.
