求翻译：锶具有两面性，一方面锶在碱性的体液环境中呈现惰性。另一方面，随着锶的增加，界面增多，对腐蚀又起着促进作用是什么意思？

Strontium has two sides, while strontium in the alkaline environment of body fluids present inertia. On the other hand, with the increase of strontium, the interface has increased, the erosion also plays a role in promoting

strontium is two-faced, strontium alkaline environment in the body fluids inert. On the one hand, the biosphere, the interface has increased, the increase of the corrosion also plays a catalytic role

The strontium has the dual character, on the one hand the strontium presents the inertia in the alkalinity body fluid environment.On the other hand, along with the strontium increase, the contact surface increases, to corrodes is getting up the promoter action

Strontium has a dual character, strontium on the one hand rendered inert alkaline fluid environment. The other hand, with the increase of SR, interface increase corrosion and plays a catalytic role

Strontium has dual characters, on one hand strontium presents the inertia in the alkaline body fluid environment. On the other hand, with the increase of strontium, the interface is increased, play a driving role to corroding again
