1、x=0,t=0时应y=0 A、B都符合. 2、x=0,t>0(刚刚大于0)时应y>0 只有B符合. 另：或者你先进行三角函数变换，x=0时，都转换成sin A 是-sin B 是sin 明显B对1年前对于这种选择题，你可以直接代入具体数字，0,5/2,5,15/2,10,就可以得出答案了。对于计算题的话，相信楼主能算到题上这一步(就是两个选一个的情况),根据代入数值法就可以了。此题答案A(在时间为5秒，x为0时，根据图像可以得到此答案) 1年前简谐振动的初相位：当时间为0时的角度即可简谐运动初相位公式是：X=Asin(2π/T+φ。简谐运动是最基本也最简单的机械振动。当某物体进行简谐运动时，物体所受的力跟位移成正比，并且总是指向平衡位置。在平衡状态的力学系统受到微扰后由于其平衡位置的特殊性
