ABSTRACT

Currently, college entrance examinations are not only limited to the knowledge learned in the textbook, but also require students to master some ideas of college physics. In order to make students cope better with the college entrance examination, and adapt to the study of college physics quickly, the teacher can analyze the complex questions of the college entrance examinations, contrast the solution of high school to university, reform the educational model, and then make good connection between high school and university.

1. 引言

2. 高中与大学物理衔接存在的问题及后果

2.1. 存在的问题

2.2. 导致的后果

2.2.1. 解答高考题变得困难

2.2.2. 大学的学习将不顺利

3. 高中物理与大学物理的衔接策略

1) 常规解法：

Figure 1. Title example

2) 微元法：

$\Delta U=k\frac{\Delta Q}{r}$

$U=\sum \Delta U=k\frac{\sum \Delta Q}{r}=k\frac{Q}{r}=k\frac{Q}{\sqrt{{R}^{2}+{x}^{2}}}$

3) 微积分法：

$\text{d}U=k\frac{\text{d}Q}{r}$

$U=k\frac{{\int }_{Q}\text{d}Q}{r}=k\frac{Q}{r}=k\frac{Q}{\sqrt{{R}^{2}+{x}^{2}}}$

1) 常规解法：

Figure 2. Title example

2) 大学解法：

${U}_{\text{0}}=k\frac{Q}{R}$ (1)

${U}_{M}={\int }_{r}^{\infty }E\cdot \text{d}r={\int }_{r}^{\infty }k\frac{Q}{{r}^{2}}\text{d}r=k\frac{Q}{r}$ (2)

${E}_{k0}+{U}_{0}q={E}_{k}+{U}_{M}q$ (3)

${E}_{k}={E}_{k0}+\frac{kQq}{R}-\frac{kQq}{r}$ (4)
