This understanding is very wrong, in theory, no filler layer is equal to no radiation surface.

这种认识是非常错误的，从理论上说，不设填充层就等于没有辐射面。

Finally it introduces the active admittance method and three designed equations which are used to design the radiation surface.

最后阐述了有源导纳法，以及设计辐射阵面的三个设计方程。

The width and surface temperature of the radiation surface are directly related to the thickness and material of the filling layer.

辐射面的宽度、表面温度与填充层的厚度和材质有直接关系。

Since cosmic radiation alters surface composition, Curiosity can drill into rock to extract pristine material from below.

But over time, the white paint would be reflecting light and other electromagnetic radiation from its surface.

Because of abundant solar ultraviolet radiation at the surface, organic molecules might not be preserved as well as clay minerals.
