使用密度计的彩色特性应该是一种相对的感觉，对于制卡和会员卡制作材料的工艺控制是非常有用的。
Use the densitometer color characteristics should be a relative sense, with regard to business card printing and membership card materials of process control is very useful.
通过对金属橡胶材料进行振动特性试验，总结了不同激励水平、不同相对密度及不同材质对其振动特性的影响。
Based on non-rigidity and non-damping, the method of describing vibration performance of MR was presented, steady response was calculated, and the results were contrast to testing results.
另外材料自身特性也是影响边界缺陷的关键因素，塑性好的材料磨削后其边界缺陷相对较少。
Finally, the property of materials is a key factor affecting the edge damage, the hard-brittle materials with good ductility have little edge damage after grinding.
