By the analysis penetration of ZnOw into the compound board will compose a microscopic damping structure, which can reduce the vibration frequency and increase the damping ratio. 分析认为,氧化锌晶须渗入在复材中将形成微观的阻尼结构,起到降低固有振动频率和增大衰减率的作用。
The rejection rate of our products this month is zero. 我们厂这个月产品废品率为零。
The four resistors that form the subtractor must have matched ratios to obtain maximum common-mode rejection. 形成减法器的四个电阻必须具有与获得最大共模抑制比相匹配的比例。
