rotation temperature
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.Its Faraday rotation has low temperature dependence,the temperature sensibility is 4.20×10 -4 (K -1 ) among 250～400 K.
3.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 .
4.High temperature rotation viscometer,high temperature microscope and scanning elec- tron microscope was used to study the effects of the constituents, such as B_2O_3,A1_2O_3and Na_2O,on the melting proccss, fusion propcrty,phase transformation and microstructure in CaO-SiO_2-P_2O_5system bioglass--ceramics.
5.Because of middle or late hybrid maize joining the rotation, a prolonged rotation circle requires more accumulative temperature around 5000-5200 degrees.
6.The results show that the optimum culture condition are: GCI culture, initiative pH 7.0, rotation speed 80r/min, culture temperature 35 ℃, culture time 72 h.
7.The size of CBO crystal grown by Kyropoulos method is 40mm in length by 25mm thick and width,growth conditions are:rotation speed is 10—20r/min,dropping temperature rate is 0.1—0.2℃/d.
8.In this paper, frequency null-drift caused by the deviation of the polarization rotation angle in the Faraday rotation mirror(FRM) from 90° is analyzed,and that it is the main source of unstability to variation of temperature is emphasized.
9.The effects of the additive concentration, temperature and rotation speed of the electrode on the coexisting adsorption states are also discussed.
10.MnBiRE(RE=Ce,Pr,Nd and Sm) were prepared by vacuum vaporation method. The influence of temperature on the coercivity and Kerr rotation was investigated.
