正常流态的光谱能量密度和辐射压强都比普通黑体大并且随温度单调增加。

Both spectral energy density and radiation pressure of the normal fluid are larger than those of the normal blackbody, furthermore, they are monotonically increasing functions of temperature.

水中放电等离子体(PPDW)具有高压、高密度和低温、低电离度的特点，人们对其辐射是否具有黑体辐射的特点一直观点不一。

Plasma in a pulsed discharge in water (PPDW) has the character of high pressure, high density and low temperature, low ionized degree.
