Hydraulic shake table is important equipment for implementing large, full-length specimen sinusoidal experiment.
液压振动台是实现大型全尺寸试件正弦振动试验的重要设备。
These problems lowered the credibility of results of sinusoidal experiment, even made the experiment impossible.
这些问题使正弦振动试验结果的可信度降低，甚至使试验无法进行。
At last an initial-boundary value problem was considered and the numerical experiment demonstrated that the linear sinusoidal wave would successively evolve non-linearly into conoidal wave.
最后我们研究了初始边界值问题。 通过数值试验证明，线性正弦波会逐步变为非线性的圆锥型波。
