随着“3+综合”考试科目改革的不断深入,那些渗透交叉学科知识的题越来越多,因此,逐步适应并加强这方面综合能力训练显得尤为重要.现分类解析和选编能力题供大家学习之用. 一、物理化学综合题解 题1:晶体二极管具有_特性.它是由半导体材料制成.单晶硅是良好的半导体材料,要提取这种高纯硅的一系列化学反应方程式为_.现将两硅半导体元件接入如图1的电路中,二极管可视为理想二极管,R1=R2,a端对b端的电压与时间的关系如图2.请在图3中作出a端对C点的电压与时间的关系图线(至少画出一个周期). With the continuous deepening of the “3+ comprehensive” examination subject reform, there are more and more questions that infiltrate cross-disciplinary knowledge. Therefore, it is particularly important to gradually adapt to and strengthen comprehensive ability training in this area. The current classification analysis and selection ability questions are available for everyone. The use of learning. First, the physical chemistry synthesis problem solving problem 1: Crystal diode has _ characteristics. It is made of semiconductor material. Monocrystalline silicon is a good semiconductor material, a series of chemical reaction equation to extract this high purity silicon For the _. now two silicon semiconductor devices connected to the circuit shown in Figure 1, the diode can be regarded as the ideal diode, R1 = R2, a terminal to b terminal voltage and time as shown in Figure 2. Please make a in Figure 3 a Diagram of voltage versus time at point C (at least one cycle is drawn).
