物理图像在我们学习物理知识的过程中,占有非常重要的作用.在中学物理课本中我们就学 习了许多物理图像.例如;力学中的匀速直线运动的st、vt图,简谐振动图像和简谐波波形图等. 热学中的一定质量的理想气体p-V、p-T、V-T图等.电学中的U-1图,正弦交流电的波形图等. 随着高考的发展,近年出现了一些新的图像问题,考试大纳中一项重要的能力要求就是“获 取知识的能力”.它要求考生能读懂自然科学方面的资料,看懂图表所包含的信息.能从文字、图 表中提取所需信息,并从中找出规律. 研究图像的一般方法是要弄清:①坐标轴的物理意义;②斜率的物理意义;③截距的物理意 义;④曲线与坐标轴所围面积的物理意义.
Physical images play a very important role in the process of learning physical knowledge. In the middle school physics textbook we have learned many physical images. For example, st and vt diagrams of uniform linear motion in mechanics, harmonic vibration images and simple Harmonic Waveforms, etc. The ideal gas pV, pT, VT diagram for a certain quality in thermals, etc. U-1 diagram in electricity, sinusoidal alternating current waveform diagram, etc. With the development of college entrance examination, some new images have emerged in recent years. Question: One of the major competence requirements in TestDaina is “ability to acquire knowledge.” It requires candidates to read natural science materials and understand the information contained in the charts. It can extract information from texts and charts. Need information, and find the law from it. The general method of studying the image is to make clear: 1 physical meaning of the axis; 2 physical meaning of the slope; 3 physical meaning of the intercept; 4 physical meaning of the area surrounded by the curve and axis .
