This paper describes a design method of multi-stage transistor intermediate frequency wide band amplifier. The feature of design is the use of network synthesis technique for realizing the amplifier with Tschebyscheff or maximal flatness frequency characteristics. The amplifier itself consists of a cascade of RC neutralized common-emitter stages each with primary tuned interstage transformer. The discussion is divided into three parts. First, the neutralized common-emitter stage is represented by approximate unilateral equivalent circuit. Second, the interstage network is analyzed. Expressed the transistor amplifier power gain as a prescribed frequency function, it is possible to derive the limiting constraints for resonant frequencies and Q values of interstage networks, and subsequently to obtain values of circuit elements. These resonant frequencies of interstage networks are not tuned to the center frequency, but distributed at certain frequencies of the transmission band. Finally one design example is presented.

本文叙述一种多级中频宽带晶体管放大器的设计方法,其特点是利用网络综合技术,使放大器的通频带具有契伯舍夫或最大平直型式的特陆曲线。放大器由中和了的共发射极级链接而成,级间用初级调谐的变压器耦合,叙述分三个部分:第一部分将中和了的共发射极电路用近似等效电路表示,第二部分分析级间网络,将晶体管放大器的功率增益表示成预给的频率函数后,就能导出各级间网络的谐振频率和Q值等,从而求出线路元件的数值。这些谐振频率并不是调谐到中心频率而是分布在传输频段的某些频率上的,最后举出一个数值设计实例。

The effects of temperature, rate of drawing, crystalline form, and the presence of oli-gomers and water in the polymer on the drawing characteristics of Nylon-6 have been studied. Experimental results indicate that the mechanism of cold drawing of Nylon-6 fibre is in agreement with Lazurkin's relaxation theory. The authors suggest that cold drawing (under Tg) of polycrystalline polymer is a relaxation process of chain segments of the noncrystalline region.

The effects of temperature, rate of drawing, crystalline form, and the presence of oli-gomers and water in the polymer on the drawing characteristics of Nylon-6 have been studied. Experimental results indicate that the mechanism of cold drawing of Nylon-6 fibre is in agreement with Lazurkin's relaxation theory. The authors suggest that cold drawing (under Tg) of polycrystalline polymer is a relaxation process of chain segments of the noncrystalline region. When the drawing temperature is higher than Tg, crystallization and recrystallization begin, the relaxation process is mainly due to the segmental motion in the crystalline region. T g and recrystallization temperature of Nylon-6 fibre are greatly reduced by the plasticizing effect of oligomer and water. Since the segmental motion is constrained by the crystalline region, the drawing characteristics of Nylon-6 fibre in α- and γ-forms are different. The effect of constraint of the more stable α-form is greater than the meta-stable γ-form. Thus the r-form of Nylon-6 is favoured for the drawing of fibre. Time-temperature superposition is sucessfully applied to the drawing characteristics of Nylon-6 fibre, and the W.L.F. equation is satisfied:log aT = - 43.3 (T - Tg)/(374.8 + T-T g)The master curve so obtained is valuable for the selection of technical conditions of fibre drawing.

本文研究了拉伸温度、速度、高聚物晶型、低聚体及水分等因素对聚酰胺-6纤维拉伸特性的影响。认为纤维冷拉伸过程是结晶不完善部分——非晶区分子链段的运动;稍高于T_g温度拉伸,非晶区和晶区内不规整部分可能结晶;在更高温度拉伸明显地产生再结晶,其时主要是晶区的链段运动。低聚体的存在增加纤维的吸水量,这种增塑作用使聚酰胺-6纤维的T_g和再结晶温度大大下降。不同晶型对非晶区的制约作用不同因此有不同的拉伸特性。α晶型位能最低,结构稳定制约作用最强,较难拉伸;γ晶型位能较高,结构不稳定,较易拉伸且不易再结晶,生产纤维应当控制这种晶型以利于拉伸。应用时-温换算原理处理拉伸等温线与等速线结果得到总曲线;以T_g为参考温度并选择合理的常数得到W.L.F.方程如下: logα_T=-43.3(T_-T_g)/(374.8+T-T_g)利用总曲线可以很方便地力生产选择合理的拉伸工艺条件。
