摘要
研究了温度对蜂蜡和樟脑制成的尖锥模型上的菱形花纹的影响。烧蚀实验在超音速风洞中进行,得到了温度与花纹波长、压力与花纹波长的关系,并分析了温度和压力对出现花纹的起始位置、出现花纹和形成稳定花纹所需要的时间的影响。
The influence of temperature on cross-hatching on cone models made of wax and camphor is studied. Ablating experiments are carried out in heated supersonic tunnels. The relation between temperature and the wavelength of hatching is obtained. The relation between pressure and the wavelength of hatching is verified. The influence of temperature and pressure on the initial position of the appearance of hatching and on the time required for both the appearance of hatching and the formation of stable hatching analyzed.
