Relationship between the gyro ’ s bandwidth and sensitivity and the resonant frequency differential ratio is derived through frequency analysis. the bandwidth of the gyro increases as the resonant frequency differential ratio increases ; but the sensitivity decreases as the resonant frequency differential ratio increases
增大驅動軸和敏感軸之間諧振頻率的頻差,可以增加微陀螺的帶寬,但是降低了微陀螺的靈敏度,這為設計石英音叉結構參數時,確定驅動軸和敏感軸諧振頻率提供了指導依據。The best dosage of dispersant and disperse medium, and the best time of ultrasonic disperse. secondly, the bp neural network process parameters model which describes the relationship between the important process parameters of the preparation of superfine quartz powder and the important evaluate guidelines was built, based on experimentation data. the forecast of the important guidelines was achieved with this model
其次,本文以試驗數據為基礎,基於bp神經網路建立了球磨法制備超細石英粉體的關鍵工藝參數(轉速,時間,裝樣率,料球比)與粉體的關鍵評價指標(中值粒徑,粗端粒徑,均勻性系數)之間多目標多變量的bp網路工藝參數模型,該模型的建立實現了粉石英制備的關鍵指標預測。Guide to the measurement of equivalent electrical parameters of quartz crystal units
