pulse source

It is found that temperature wave frequency at a given location in the slab is relevant to slab's thickness and its thermal relaxation time while the amplitude of temperature wave bears a relation with heat source's distribution area and pulse duration.

研究结果表明，温度波动频率取决于平板厚度和材料的热弛豫时间，而其幅值则与内热源释放区域的大小和脉冲宽度的长短有关。
