求翻译：同时，由于旋涡的作用力，其中心物质会呈快速下降的趋势，从而把其表面物质的一部分能量带到其旋涡的底部并聚集。这就是太阳上的黑子为什么其表面的温度总是低于其周围表面物质的温度，而其底部的温度一定会高于其表面周围物质的温度的原因。是什么意思？

Meanwhile, the vortex force, the material will be its center was a rapid decline to the surface of the material part of its energy to the bottom of the vortex and aggregation. This is why the sunspots on the sun its surface temperature is always lower than the temperature of the surrounding surface

And, as the role of power, and its Center for whirlpool material will be presented to the rapid decline of its surface, material, the amount of energy into the whirlpool of and gathered at the bottom. This is why the sun, the black son of surface temperature is always lower than the surrounding surf

At the same time, as a result of the whirlpool action, its central material can assume the fast drop the tendency, thus to its whirlpool base and gathers its superficial material part of energy bands.Why is this on sun's black mole its surface temperature always is lower than its periphery superfici

At the same time, due to the Vortex force, its central substance is rapidly declining trend, thus bringing its surface energy part of the matter to the bottom of the whirlpool and aggregation. This is why solar sunspots on its surface temperature is always below the surface temperature of the materi

Meanwhile, because of the effort of the swirl, its material of centre will present the fast downward trend, thus take their bottom of swirl to and assemble its superficial some energy of material. This black mole at the sun why their superficial temperature lower than surface temperature of material
