Under UHV condition, the C-O stretching mode properties of diacetate cellulous (C_2H_8O_3-(COOCH_3)_2) adsorbed on polycrystalline Ag surface were studied by using PAS. 本工作在超高真空条件下用光声谱(PAS)研究了有机大分子双醋酸纤维素(C_2H_8O_3·(COOCH_3)_2)吸附在多晶Ag表面的振动模性质。
The increase of cellulous fiber in the hybrid fiber can result in the increase of optimum asphalt content, the reduction of density, air voids and Marshall stability. 同时随着混杂纤维体系中木质素纤维比例的增加，沥青混合料的最佳沥青用量增加，密度下降，空隙率和马歇尔稳定度呈减小趋势。
The pavement performances of asphalt mixtures containing hybrid fibers can be improved.The enhancement of hybrid fibers is more significantly than the single cellulous fiber to some extend. 混杂纤维的掺加能显著提高沥青混合料的路用性能，且在一定程度上，混杂纤维的增强效果比单一木质素纤维更加显著。
With the deep research of enzymatic hydrolysis of cellulase, the traditional view of "no cellulase in higher animals themselves " was pulled down and animal cellulase became the hotspot of cellul... 另外,生物化学、分子生物学以及基因工程等多种交叉学科的快速发展,获得适合工业化的高比活力的纤维素酶已指日可待。
