As the lightest constructional material, magnesium alloy has high specific strength, high specific stiffness, good magnetic-shielding ability, good damping ability, and good machinability.
镁合金是比重最轻的结构材料，具有高的比强度、比刚度和良好的磁屏蔽性、阻尼性、切削加工性等优点。

Accordingly, an air gap between the damper base and the damper cap can have a uniform clearance, and lowering of a viscous damping force due to excessive abrasion of a specific part can be prevented.
In 1985 Sir Aaron discovered a new class of proteins that mimic this function and can recognise specific stretches of DNA and bind to them, boosting the activity of genes or damping them down.
