数学作为一门基础学科.在研究物理问题中显得尤为重要.下面是我在教学中的一点体会。一、用科学记数法书写物理数据。如一张纸厚度用米作单位.不写成0.0001米而写1×10~(-4)米。二、“三点一线”的应用。因光在空气中沿直线传播.射击瞄准时目标、准星、缺口要共线也即应用了以上原理。三、用数学表达式反映物理规律。阿基米德定律为F_浮=G_拌=ρ_滚 gv_排表示时.意 Mathematics is a basic discipline. It is particularly important in the study of physics. The following is my experience in teaching. First, use physical notation to write physical data. If a piece of paper thickness is in meters, do not write 0.0001 meters and write 1 x 10~(-4) meters. Second, “three point line” application. Because the light travels in the air in a straight line, the above principles apply when aiming, sighting, and notching are to be collinear. Third, use mathematical expressions to reflect the laws of physics. Archimedes’s law is that F_float=G_mix=ρ_roll gv_row indicates time.
