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. 分析認為，氧化鋅晶須滲入在復材中將形成微觀(guān)的阻尼結構，起到降低固有振動(dòng)頻率和增大衰減率的作用。
The rejection rate of our products this month is zero. 我們廠(chǎng)這個(gè)月產(chǎn)品廢品率為零。
The four resistors that form the subtractor must have matched ratios to obtain maximum common-mode rejection. 形成減法器的四個(gè)電阻必須具有與獲得最大共模抑制比相匹配的比例。
