比表面积随催化剂制备温度和制备时间的增加而减小。
The specific surface area of catalyst decrease with preparing temperature increasing.
从而大幅度地降低了样品制备时间并且提高了消解品质。
This drastically shortens the time required for sample preparation while improving the decomposition quality.
随着改性制备时间的增加,橡胶沥青高温、低温以及粘弹性能均先增加再下降。
With the increase of reaction time, the high-temperature, low-temperature and the viscoelastic properties, first increase then drop.
