As you reach the speed of light, relativity calculations indicate that an object's mass becomes infinite.
如果达到光速，根据相对论可以计算出这个物体的质量趋于无穷。

In fact, objects with mass, be they cars or neutrinos, can't reach the speed of light because they would need infinite energy to do so, according to the theory.
The temperature of surface zone in mass concrete under different boundaries is controlled by semi infinite model, and is transferred to and calculated by an equivalent .
