Cascaded Second-Order Processes and Third Order Optical Nonlinear Effects in BBO Crystal
Tan Huiming,G. P. Banf
Vol. 2, Issue 6, Pages: 7-17(1994)

Abstract：The cascaded second-order proceses in nonlinear optical crystals is discussed.In smallsignal conversion condition,the processes are formularized by third order susceptibilities.Weresearched the cascaded second-order processes in BBO crystal with self-phase modulationand optical frequency mixing experiments.We found that since cascaded second-order pro-cesses, the third order nonlinearity is enhanced evidently and the susceptibility is about 10^-19m²/V².

Varying Characteristics of Motor Instantaneous Current in Vari-speed Cutting Process
Hong Li,Yang Fulun,Yu Junyi
Vol. 2, Issue 6, Pages: 24-31(1994)

Abstract：The varying characteristics of motor instantaneous current in vari-speed cutting are dis-cussed in this paper.The theoretical analysis and experimental results demonstrate that themotor current has some fluctuation in vari-speed cutting process,but it is almost no effect onnormal operation of motor because the increase amplitude of motor instantaneous current isabout 20 percent if the vari-speed parameters is appropriate.It is not restrictive factor to popularize vari-speed cutting.

Application of Secondary Electron Conduction Target Vidicon In Slow Deflection TV System
Zhao Bingyi,Xia Jianming,Tong Ruilin
Vol. 2, Issue 6, Pages: 45-52(1994)

Abstract：The relation between target signal current and deflecting rate of the secondary electron conduction target vidicon(SECTV)which has accumulating effect is presented.When theSECTV is used in slow read out,sample read out is used to increase the reading signal cur-rent.The picked-up depth of target charges is related to the target voltage. The method todefine the optimal value of target voitage is given,Some technological problems in using theSECTV and its solved methods are discussed.
