通过对贵州红粘土大量实验数据的统计和分析,发现贵州红粘土的稠度状态有其自身的特点:一是用含水比划分出在自然状态下贵州红粘土常处于硬塑和可塑状态且有地域性差异;二是用液性指数对贵州红粘土稠度状态进行划分,其结果与用含水比划分结果有较大偏差.结合红粘土特殊成分结构分析,认为其原因是红土化作用的程度不同和土中存在大量结合水.采用代数转换的方法分析得出适合贵州红粘土稠度状态划分的液性指数等效范围,便于与其它土类状态划分范围进行对比,体现贵州红粘土稠度状态划分上的特殊性. 相似文献

Site testing results indicate that Antarctic Dome A is an excellent ground-based astronomical site suitable for observations ranging from visible to infrared wavelengths. However, the harsh environment in Antarctica, especially the very low temperature and atmospheric pressure, always produces frost on the telescopes' mirrors, which are exposed to the air. Since the Dome A site is still unattended, the Antarctic telescope tubes are always designed to be filled with dry nitrogen, and the outer surfaces of the optical system are heated by an indium-tin oxide thin film. These precautions can prevent the optical surfaces from frosting over, but they degrade the image quality by introducing additional mirror seeing. Based on testing observations of the second Antarctic Survey Telescope (AST3-2) in the Mohe site in China, mirror seeing resulting from the heated aspheric plate has been measured using micro-thermal sensors. Results comparing the real-time atmospheric seeing monitored by the Differential Image Motion Monitor and real-time examinations of image quality agree well. 相似文献
