声速

1.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的高超声速风洞烧蚀实验研究的结果。

2.The changing of the structure and properties of UHMWPE fibres during super drawing were studied by means of SEM, DSC, WAXD and sound pulsimeter.

还借助扫描电子显微镜（SEM）、热分析（DSC）、广角X射线衍射（WAXD）、声速手段研究了UHMWPE熔纺丝在超拉伸过程中结构性能的变化。
