One of the most fundamental quantities in the study of various parametric applications of the varactors is its nonlinear characteristics. The required pumping power can be greatly reduced if a varactor having much higher nonlinearity is employed. For the purpose of studying either lower pumping applications or non-sinusoidal pumping applications of the varactor, a knowledge of both the fundamental and the harmonics of the pumped time-varying parameters of the varactors is highly desirable. An analysis on the proper selection and normalization of the non-linear characteristics of the varactor is offered. A graphical method to analyze the fundamental and the harmonics of the pumped time-varying parameters was employed, and curves relating these components to the nonlinearity of the varactor r, and the pumping voltage ratio m1 were obtained. These curves serve as one of the fundamental references in various varactor parametric applications. Sample applications are also included as illustrations.

The new findings of this paper are: a set of nonlinear algebraic equationsfor solving the offset response of a flexible rotor-uncentralised SFDB (squeezefilm damper bearing) system is derived, so that the coupled motion of rotordisk and bearing journal is separated and the computing time is saved greatly.Before giving a detailed introduction of these findings, believed to be new, itis necessary to have a brief summary of the previous researches about thissubject. Because of the high nonlinearity of squeeze film force, many problemsabout rotor-SFDB system have not been th(?)r(?)ughly analysed. The offsetsynchronous response of the system can only be solved by direct integrationmethod, thus it needs large quantity of time and the motion coupling of rotordisk and bearing journal increases the complication of analyses. For nonlinearsystem, if the nonlinear force can be linearized, undoubtedly the responseanalyses will be simplified. But up till now, only for centralised SFDB, canthe nonlinear film force be linearized with steady state circular response; noeffective linearizing method exists for the offset response of uncentralisedSFDB. In order to simplify the response analyses of flexible rotor-uncentralisedSFDB system, the Equivalent Linearizing Method advanced in references [5] and[6] is used in this paper for solving the offset synchronous response of thesystem; the nonlinear fluid film forces are linearized with offset synchronousresponse and a set of nonlinear algebraic equations for solving the offsetresponse is obtained. In this set of equations, the motion of rotor disk can berepresented by the motion of bearing journal, so that the system's degrees offreedom are decreased. Besides, as the problem of solving differential equationsis replaced by solving algebraic equations, the computing time can be savedobviously and the analyses are simplified. Numerical results show that theequivalent solution is very near the real solution in the first harmonic appr- oximation, and that the equivalent linearizing method can save computing timegreatly compared with direct integrating method.

What makes the temperature control of the annealing furnace difficult is the variation of process parameters, the high nonlinearity, heavy noise and the large time delay of the process. In this paper, the applications of fuzzy control theory to the annealing control is reported. A modified fuzzy controller structure which has faster response and higher accuracy is used to control the temperature and the pressure of the furnace. And a fuzzy self-optimal controller with the aid of fuzzy sets theory is used to regulate the fuel/air ratio to keep a rational combustion. The operation run shows that the fuzzy control system can overcome the above difficulties, and the result is satisfactory.
