rotation coefficient
1.The Faraday rotation temperature coefficient of a new type TbYbBiIG bulk crystal is -2.3×10 -2 (deg/mm·K) in temperature range of 10°C to 80°C and it is expected to be used as a more practical Faraday rotator for optical isolator with temperature stable isolation.
2.On the basis of analyzing parameters for mixture condition, the paper took the rotation speed, mixing time and filling coefficient as main factors affecting mixing guality, and an orthogonal experiment was carried out for determining the optimal combination of working parameters. The results showed that the agitator had a mixing grade of more than 90%, when rotation speed was 23 r.
3.Slide and rotation process of car accident after collision and equivalent adhesion coefficient are illustrated. Finally a practical accident example is calculated by simplified computer program compiled by the authors.
4.After annealing,the Faraday rotation at room temperature is about 1.9×10 4 deg/cm at 633nm,the absorption coefficient is about 2500cm -1 .
5.Processing method of chord_integral spectral signal has been discussed. Radial profile of spectral line emission coefficient has been derived from the distribution of intensity by Abel inversion. The local ion temperature and rotation velocity has been obtained from the line shape by a chosen_point fitting technique.
6.Due to large tramsmission coefficient crystal led high abscissa temperature gradieut,the crystal only with large convex degree(natural convection)or with large concave degree(forced convection)was grown,so that obvious interface inversion is able to appear and it is located in the top of the crystal when rotation rate is suitable.
