The experimental results of low temperature ablator (beeswax and camphor) tests in the hypersonic wind Tunnel are presented in this paper.

本文给出了低温烧蚀材料高超声速风洞烧蚀实验研果。

The leading candidate for Orion's base heat shield is a material called PICA (phenolic impregnated carbon ablator).

前底部防热盾首选是酚充填碳烧蚀挡板材料（PICA），是一种埋在酚树脂中碳纤维交叉构。
