  • crumb : n 1 〈常 pl 〉（麵包的）碎屑；碎片；團粒。2 麵包心 （opp crust）。3 些少，少許。4 〈美俚〉可鄙的...
  • structure : n. 1. 構造，結構；組織；石理，石紋。2. 建造物。3. 【化學】化學結構。4. 【心理學】（直接經驗中顯現的）結構性，整體性；整體結構。adj. -d ,-less adj.
  1. Microfloral activity in worm may have an important effect on soil crumb structure.

    蚯蚓類中微生物群落活性對土壤團粒結構可起重要作用。
  2. Crumb structure the texture of a soil in terms of the size of the soil particles and how they interact, often determined simply by rubbing the soil with fingers

    團塊狀構造：根據土壤顆粒的大小及顆粒之間的相互作用而決定的土壤的質地結構。
  3. Some soils, such as sandy soils, have a loose crumb structure with good drainage, whereas in clay soils the particles are small and stick together to give a dense crumb structure and poor drainage

    一些土壤例如砂土具有鬆散的結構，因而有良好的排水性，而在粘土中，由於土壤顆粒小而互相粘合導致粘土結構緊密排水性較差。
  4. The results are summarized below : 1 ) study on soil science indicates that soil granular structure is the focus adjuster for soil fertility and it affects the space, water - grasp, aeration and anti - erosion of soil. and the percentage of aggregate is one of the key index that decides the speed and extent of soil erosion, hardening and degeneration because the soil degeneration will first lead to the disappearance of crumb - structure. so it is very important that the physical course and character of soil in different land use pattern are realized

    現將主要結果摘要如下： l 、士壤學研究表明，團粒結構是土壤肥力的中心調節器，影響著土壤的空隙性、持水性、通透性和抗蝕性；任何土壤的退化首先將表現出團粒結構的消失；團聚體百分比是決定土壤侵蝕、板結等物理過程速度和幅度的關鍵指標之一，了解不同土地利用和土壤管理方式的物理過程和性質相當重要。
  5. Experimental study on structure of crumb rubber lightweight concrete

    結構用橡膠輕集料混凝土的性能實驗研究
  6. The addition of lime to saturated clay soils ( liming ) is a common agricultural practice, improving soil structure by encouraging crumb formation and making heavy soils more workable

    加入石灰使其飽和是農業上常用的一種方法，通過促進小塊形成改變土壤結構，使粘重土壤變得可以使用。
