The research results indicated that by comparing the differences between aggregate moments of inertia to x axis and to y axis , i . e . , the index of the aggregate distribution in asphalt mixture , it is feasible to evaluate quantitatively segregation 研究结果表明:通过比较混合料截面上的集料对x轴和y轴转动惯量的差异(集料的分布状态指标) ,可以定量地评价混合料的离析状况。
The study also indicated that all the tree species but keteleeria evelyniana appearing to have an aggregate distribution had a random distribution in the canopy layers and all the dominant species had a aggregate distribution in the renewal layers 研究还表明,在林冠层中,除了滇油杉在山坡上部为聚集分布外,其他树种的分布格局均呈随机分布;在更新层中,优势种类均为聚集分布。
From the aspect of soil characters , aggregate distribution and stability as well as aggregate stability mechanism of ferrisols were studied in this paper , which would have great importance in reducing water erosion danger , stabilizing and improving agricultural production , preserving soil resources and balancing soil ecological system 本研究应用多种方法,从团聚体稳定性的角度,研究富铁土对水力侵蚀的敏感性并探讨其影响团聚体稳定的物理学机制,对于减小水蚀危害、保护土壤资源、维持和提高生产率、维护土壤生态系统平衡具有重要意义。
The results of aggregate distribution and stability on ferrisols used by le bissonnais ' s method suggested that , treatment method and initial size had greatly affected on aggregate stability and aggregate distribution . fast wetting ( fw ) treatment had the largest disruption while wet - stirring ( ws ) treatment had the lowest disruption 采用lebissonnais法的三种处理方法测定富铁土的团聚体分布与团聚体稳定性的结果表明,湿处理后的颗粒分布随处理的不同以及初始团聚体的大小不同而变化很大。
