It can guarantee the coastingbody not over-sink or over-float with the support of light-load spring under light load and heavy-load spring under heavy load.
轻载时由轻载弹簧支承，重载时重载弹簧加入承重，保证惯性体不会超限下沉或上浮；

Therefore, the vibration-avoiding machine should meet the strict restrictions on the lifting distance of the coastingbody caused by weight variation in different working periods.
因此，避振器须满足惯性体由各工作阶段的重量变化导致的升降距离变化的严格限制；

This means the body doesn't face any new problems, beyond those already present at 90.Professor Rose says that those wanting to fast-forward to this ‘coasting’ stage should look to their diet.
