At the confluence zone, due to the jacking of current from main stream and tributary stream, the mixing and turbulence of current is so strong and the loss of energy is so large that the balance of water and sediment is broken which could causes sediment particle and coarse grain to deposit and forms shallow shoal at river mouth or eyot.
天然河流中存在着大量的干、支流交汇的河段,在干支流相汇处,由于干、支流两股水流相互顶托,交汇区内水流紊动掺混作用强烈,能量损失很大,干、支河流原有的水沙平衡状态被打破,可能导致泥沙颗粒、尤其是粗颗粒卵石在汇合口处大量淤积,形成河口浅滩或江心滩。

Results showed that the topsoil structure of the CK treatment was dense with little porosity developed, and the soil microstructure was sandy granular fabric - granular fabric. In these treatments using chemical fertilizers only, the soil particles did not form soil structure with little porosity, and the soil microstructures in the N, NP or NPK treatment were observed as prophyropectic fabric-fine sand agglomerplasmic fabric, much better than the CK treatment. In those treatments receiving farm manure alone or farm manure plus chemical fertilizers, the quantity of groundmass increased obviously. The soil had a loosen structure, higher porosity, enriched animal and plant residua, iron-manganese nodules and humus, and more micro-aggregates developed. The soil microstructure of the MNPK treatment was pectized-compacted takyric fabric-intertextic fabric, the best microstructure observed among all the treatments.
结果表明:长期不施肥料的CK处理,土壤耕层结构致密,很少有孔隙发育,土壤微结构为结构较差的碎屑聚积状-沙粒聚积状;长期单施化学肥料,土壤颗粒未形成结构体,少孔隙,土壤微结构主要为斑晶胶凝状-细沙粒聚积状结构,土壤结构比CK处理优;长期施用有机肥或有机无机肥料配施的处理,土壤粗颗粒数量显著增加,结构疏松,孔隙量大,动、植物残体丰富,有铁锰结核和腐殖质的形成和微团聚体的发育,土壤微结构类型以MNPK处理最好,为胶凝紧实状-多孔状结构。

By the combination of experimental results with theory of crystal growth, some growth models and growth mechanisms were proposed. Research results confirmed that pillar-shaped TaC whisker with spherical droplet at the end grew via a vapor-liquid-solid mechanism, pillar-shaped whisker with pyramid-like end was formed via a vapor-solid mechanism, awl-shaped TaC whisker with zigzag end formed via a liquid-solid mechanism, awl-shaped TaC whisker with growth step at the end has a growth mechanism of screw dislocation mechanism. The growth mechanism of dumbbell-shaped MgO nanowhisker and NaCl particle-decorated MgO nanowhisker is VS; C and MgO powder-yielded MgO nanowhisker was formed via a VLS mechanism, Mg powder-yielded MgO microwhisker and MgO microsized or nanosized crystal sheet grew via a VS mechanism. In the Si and SiO〓 nanostructures, Si nanowires formed in higher-temperature zone grew via oxide-assistant mechanism, while Si nanowires or nanorods formed in lower-temperature zone have a growth mechanism of VLS, and the growth mechanism of SiO〓 nanowires is VS.
