Long service time and excessive vibration of aero-engine will cause failure of clamps, which usually fix Kids Footwear pipelines on the outside of an aero-engine.In this paper, the nonlinear vibration characteristics caused by loosening clamps in aero-engine pipeline are determined.According to the real parameters of an aero-engine clamp-pipeline t
Adaptation is a common feature of many sensory peeler systems.But its occurrence to pain sensation has remained elusive.Here we address the problem at the receptor level and show that the capsaicin ion channel TRPV1, which mediates nociception at the peripheral nerve terminals, possesses properties essential to the adaptation of sensory responses.C
