目前多数学校已配备了J2459型学生示波器,但课本中用它做的实验较少,如果把一些演示实验改为学生分组实验,既有利于加深学生对物理规律的认识和能力的培养,又可使它发挥更大的作用。下面就介绍两个用学生示波器配合少量常用器材可进行的学生实验。 At present, most schools have been equipped with J2459 student oscilloscopes, but there are few experiments done with it in textbooks. If some demo experiments are changed to student group experiments, it will not only help students to deepen their knowledge of physical laws but also develop their abilities. Make it play a bigger role. The following describes two student experiments that can be performed with student oscilloscopes and a few common devices.
