摘要
首先给出了弹簧振子在定常摩擦阻力作用下的振动微分方程ｘ＋ｗ＾ｘ＝±φ，并通过分段求解，归纳出其在各个阶段的解的一般形式，然后根据振幅衰减规律及振动能够维持的半周期数，用Ｑｂａｓｉｃ编程，作出了振动的图象．
At first, x + w2x = + o , the differential equations of the oscillation of spring oscillator under constant friction resistance are given, and the general form of the solution for each stage is induced after being solved stage by stage. Then, according to the regularity of amplitude attenuation and the number of semi-periods of oscillation, the programs are written, and the graphs of oscillation are drawn by Qbasic.
