melt number的意思|示意

This image above shows 2010 compared to the average number of melt days per year between 1979 and 2009.

上面的图像把2010年冰雪融化的天数与1797 - 2009年期间每年冰雪融化的平均天数作了比较。

The new study focused on surface melt, runoff and the number of days when bare ice, free of snow, is exposed to the Sun's radiative force.

这项新研究的重点是表面融化，径流以及暴露于太阳辐射下的裸冰和无雪天数。

The results showed that with the increase of cleanness of the melt, the number of grain per unit volume increased at first, and then decreased.

证明随着熔体洁净度增大，单位体积中的晶粒数将先增加，然后减少。
