为了抵御高温和辐射，探测器里的仪器将处于一个巨大的由碳复合材料制成的隔热罩的保护之下，但这个隔热罩目前还没完成。

To withstand the temperatures and the radiation, the instruments will be protected by a huge carbon-composite heat shield that still needs to be built.

前机罩护栅出风口朝向斜下方，减少了对发动机的热辐射，增强了冷却系统的可靠性。

The downward air outlet of front protective cover reduces heat radiation against the engine and improves reliability of cooling system in the meantime.

其分析结果表明改进效果良好，排气歧管罩的辐射噪声得到明显降低。

The analysis of the improved structure shows that the measures are effective, the radiate noise of the cover is decreased distinctly.
