depolarization degree

The formula expresses that the perfect Lyot depolarizers in Fiber-optic depolarized gyro(Dep-I-FOG) can still be affected by the axial magnetic field,and this may result in Faraday nonreciprocal phase error to gyro.

运用琼斯矩阵,基于单色光,导出了与消偏器绕向平行的轴向磁场,仍能对去偏光纤陀螺中理想的消偏器产生影响,从而给陀螺带来Faraday非互易相位差的具体公式,并给出了此相位差随保偏光纤扭转率变化的仿真结果和加磁场后的实验结果。

Method The rat primary cultured neurons were damaged by glutamic acid,the membrane lipids fluidity was studied with fluorescence polarization(P) and mean microviscosity(η) with DPH as a probe;the protective effects of puerarin on this model were evaluated by lactate dehydrogenase(LDH) efflux assay and colormetric MTT assay.

方法建立大鼠原代神经细胞谷氨酸损伤模型,以1,6-二苯基-1,3,5-己三烯(DPH)为探针,用荧光偏振法测定荧光偏振度(P)值和微粘度(η),研究细胞膜脂流动性的改变;MTT(四甲基偶氮唑盐)法、培养介质乳酸脱氢酶(LDH)活力测定观察葛根素的保护作用。

From the above it was given that the nonlinearity makes the frequency-mixing output signals shift and undulate,and its main factors are the perfection degree of the optical system adjustment and the polarization splitting degree.

根据理论分析推导出了存在非线性时输出信号的表达式,并据此给出了非线性误差的表现形式是使混频输出信号产生漂移起伏,主要影响因素是偏振分光镜分光偏振度及光路调整理想程度。
