摘要
探讨了体效应振荡器特性观测与使用实验中 ,编写实验原理要应用能带结构解释负阻特性并通过对偶极畴生长和运动过程的描述说明振荡原理 ,提出了实验教学方案 。
How to explain the negative-resistance effect qualitatively by use of energy-band structures, and how to illustrate the theory of the surge with the description of the growth and movement of the dipolar domain when writing the experiment principle are discussed. It presents a teaching project including five contents, and explains the benefit and feasibility of offering this experiment through teaching effects.
