Simulated results demonstrated that the generated aggregate patterns were very similar to practical aggregate distributions 模擬結(jié)果表明,所生成的骨料分布圖案與實際骨料分布十分相像。
Based on digital image processing techniques , the aggregate distribution of asphalt mixture was studied directly in this paper 摘要基于數(shù)字圖像處理技術(shù),對瀝青混合料中集料的分布狀態(tài)進行直接的研究。
Among the 88 species with more than 15 individuals , 87 . 5 % had an aggregated distribution pattern , and 9 . 1 % species were randomly distributed 研究中將樹木依胸高直徑分成四個生長階段,并比較整個樣區(qū)及各生育地及?同徑級大小植物分布?型之差? 。
Based on digital image processing techniques , the aggregate distribution in hot - mix asphalt , i . e . homogeneity was studied directly in this paper 摘要基于數(shù)字圖像處理技術(shù),首次對瀝青混合料中集料的分布狀態(tài),即瀝青混合料均勻性進行了直接研究。
In aggregates distribution after two treatments , the size of < 0 . 05mm was the highest percentage while 0 . 25 - 0 . 15mm size was the lowest for the initial 5 - 2mm size aggregate 初始大小為5 - 2mm的團聚體經(jīng)兩種處理分散后的粒徑分布均主要集中在0 . 05mm級, 0 . 25 - 0 . 15mm粒級最少。
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 研究結(jié)果表明:通過比較混合料截面上的集料對x軸和y軸轉(zhuǎn)動慣量的差異(集料的分布狀態(tài)指標(biāo)) ,可以定量地評價混合料的離析狀況。
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 研究還表明,在林冠層中,除了滇油杉在山坡上部為聚集分布外,其他樹種的分布格局均呈隨機分布;在更新層中,優(yōu)勢種類均為聚集分布。
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 本研究應(yīng)用多種方法,從團聚體穩(wěn)定性的角度,研究富鐵土對水力侵蝕的敏感性并探討其影響團聚體穩(wěn)定的物理學(xué)機制,對于減小水蝕危害、保護土壤資源、維持和提高生產(chǎn)率、維護土壤生態(tài)系統(tǒng)平衡具有重要意義。
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法的三種處理方法測定富鐵土的團聚體分布與團聚體穩(wěn)定性的結(jié)果表明,濕處理后的顆粒分布隨處理的不同以及初始團聚體的大小不同而變化很大。
