- 摘要：A new approach to AI control is described, which possesses the marits of fuzzy control as well as that of conventional control and can carry out a series of experts’ functions by means of an AI software. Results of laboratory tests and operations of a practical control system show that the qualities of the AI temperature-controller is excellent. A temperatur-controlling system using this AI controller realizes a best quality of control: the temperature stability obtained is better than 0.0004K/h in the measuring range 13120K.3|137|16更新时间：2025-12-08

- 摘要：A new method is given for finding out roots of one type of nonlinear equations, which appears in Van der Horst and Berger’s Complete decoding of triple-error-correcting binary BCH codes. When m is even, the new complete decoding of triple-error-correcting binary BCH codes with n = 2m - 1 requires only extracting the roots of quadratic equations and calculating at most m times inner products of m-dimensional vectors over GF（2）. The new complete decoding is very simple, and can be realized in practice even for moderate m.2|56|0更新时间：2025-12-08
- 摘要：The electrical field radiated by the unit current in a rectangular waveguide with a short-circuiting plunger is derived by making use of the auxiliary potential function. When the dominant mode TE10 is propagated alone in the rectangular waveguide, expressions for the real and imaginary parts of the input impedance seen by the coaxial line are derived. Theoretical calculation is in close agreement with experimental results.2|39|0更新时间：2025-12-08
- 摘要：CMOS/SOI devices are fabricated on Ar+ laser recrystallized polysilicon islands on SiO2 isolating layers. Both N-channel and P-channel MOSFET exhibit good output characteristics. The low field electron and hole mobilities of MOSFET with a channel length of 4 μm are 510cm2/V.s and 142cm2/V.s respectively. 6-stage CMOS inverters have fine static and transient characteristics. 9-stage CMOS ring oscillators with P-channel transistors of （W/L） = （112μm/6μm） and N-channel transistors of （W/L） = （52μm/6μm） are fabricated. The minimum propagation delay is 2.8ns/stage, and the minimum power delay product is 2.6pJ/stage. These speed performance of CMOS/SOI devices are superior to those of the same CMOS devices fabricated on bulk silicon.2|34|3更新时间：2025-12-08
- 摘要：A novel InGaAs phototransistor is proposed. CdO has the properties of high conductivity （σ =5×103Ω-1cm-1） and wide forbidden gap （Eg（г） =2.5eV）,thus it is used as the wide emitter for the transistor. Experimental results show that the transistor has a wide spectral response （λ, =0.51.6μm）. A current gain h e = 10 （VCE = 3V, Ic=1mA） is obtained. Other results including Ⅰ-Ⅴ characteristic of the emitter junction, hfe-Ic characteristic and dark current behavior are also presented.2|21|0更新时间：2025-12-08

- 摘要：A sampling theorem for narrow-band signals is developed, the sampling frequency can be lower than the Nyquest frequency of the signal when the spectrum of the signal to be sampled is limited in a narrow interval. With this theorem a very simple and clear method for the design of multirate filters is derived. The characteristics of multirate digital filters is discussed as well, and some conclusions differing from those presented in others paper is obtained.2|112|5更新时间：2025-12-08

- 摘要：An equation which reveals the general relationship between the sensitivities of a wave digital filter and the associated reference filter is derived. With this result, the low sensitivity of wave digital filters, which was observed numerically and experimently, can be well explainted theoretically. The result also provides an efficient way of computing the sensitivity of a wave digital filter from that of the associated reference filter, and may be useful for optimization of wave digital filter hopefully. A numerical example for sensitivity computation is given to illustrate the use of the result.2|24|1更新时间：2025-12-08

- 摘要：Based on the analytical solution of RSJ model with the existence of external radiation, a method for finding voltage response and RF impedance of superconducting weak links is proposed and discussed. Taking the lowest approach, the analytical expressions of the voltage response and RF impedance are obtained with this method. The results show that the impedance varies continuously on the IVC from the 0th current step to the 1st step. The analytical impedance expressions within the range of the 1st current step are deduced for the first time.2|12|0更新时间：2025-12-08

- 摘要：The formation and annealing behavior of the normal donor （TD） and new donor （ND） in NTD CZ Si are studied by Hall effect, electrical resistivine and IR absorption measurements. The apparent TD concentration is decreased obviously and the ND formation can be promoted by neutron irradiation. The main cause of ND formation in NTD CZ Si is that the oxygen atoms aggregate in the disordered region due to radiation enhancing diffusion to form large size complicated silicon oxygen complex.2|33|2更新时间：2025-12-08
