如何减少静电对汽车音响的影响

随着汽车行业的飞速发展,车辆的驾驶者对车载多媒体的要求也越来越高,从以前最简单的收音机、CD播放机,到车载导航、行车辅助系统,汽车音响的含义也越来越广泛。然而系统越复杂受到外界干扰的几率就越大,静电就是一个最大的潜在威胁,如何解决这一课题将是我们必须要面对的。     

Supper strong nanostructured TWIP steels for automotive applications

A ductile and super strong nanostructured twinning-induced plasticity(TWIP) steels were fabricated by cold rolling and recovery treatment.This strong and ductile nanostructured alloy can be used for the anti-intrusion part of body-in-white. Cold rolling was used to produce intensive nano-twins so that the microstructure was greatly refined. Recovery is employed to anneal dislocations for improving the ductility. A physical model is proposed to describe the relationship between the yield stress and the twin density. Furthermore,the present work also found that the activation energy for recovery is 160 J/mol,which implies that the recovery mechanism is governed by dislocation core diffusion.
