Oxgen precipitates (useful for gettering) can reduce the yield strength (critical shear stress) up to fivefole.

氧沉淀（吸杂）会使屈服强度（临界剪应力）降低为五分之一。

Bioreactor can improve nutrition transmittability, provide hydrodynamic environment, induce shear stress, and promote production of cartilage specific matrix protein.

生物反应器提高营养传输能力，提供流体动力环境，施加液诱导剪应力，而软骨特异性基质蛋白的合成。
