As the main research institute of ring laser gyroscopes in china, teaching and research section 208, nudt, is always puzzled by the problem of null - shift in the process of developing mechanically dithered ring laser gyroscopes ( mdrlg ). the problem is that the mdrlg ' s null shift equal to the integral times of dither periods when the sample time is set as integer dither periods
作為國內激光陀螺主要研製單位的國防科大208室，在機械抖動激光陀螺（機抖陀螺）研製過程中一直為零漂問題所困擾：實驗測得機抖陀螺零漂為抖動周期（采樣時間取整數個抖動周期）的整數倍。 -
Thus the principle to deal with the four basic waveforms is put forward and a new phase - demodulation circuit is designed. experiments for the two circuits on same gyros are made and they indicate clearly that the mdrlg ' s null - shift problem consists in the faultiness of the old phase - demodulation circuit
在此基礎上，提出了處理計數信號過鎖區波形的基本原則，進而設計了新的鑒相電路，並在同一陀螺上對兩鑒相電路進行了對比實驗。 -
In the end, null shift and scale factor of the newly developed mdrlg is tested. random walk of the gyroscope is 0. 0163 ?, rms of drift is less than 0. 09 ? h, relative precision of scale factor is better than 10 ppm
最後對新研製的機抖陀螺進行了漂移和比例因子測試，實驗測得陀螺隨機游動系數為0 . 0163 / h ~ （ 1 / 2 ） ，漂移均方差小於0 . 09 / h ，比例因子相對精度優於10ppm 。 -
The null point shift in three - phase load is studied by using the equation of circumference and an arc and the changing law of the null point shift is discussed qualitatively
運用圓弧方程和圓圖分析了三相負載中點位移的特性，定性討論了中點位移的變化規律，這對加深理解中點位移和實際應用有參考意義
