soil boundary

We use interpolation search to find soil boundary, select a representative survey routes to dig and name the main profile, the use of checks and delimitation of section profiles to determine cut-off point and to determine the soil line.

土壤界线通过内插法寻找，选择有代表性的调查路线后对主要剖面挖掘定名，利用检查剖面和定界剖面确定分界点，进而确定土壤界线。

This repsents a boundary where the water seeps out of the soil into air.

这个边界是水从土层中渗出进入空气的地方.

粘性土三相间相互作用及对相关指标的影响非等温边界层中相间相互作用实验研究

A multi-purpose triaxial apparatus, that can strictly control the boundary force and apply the tensile or compressive force along vertical axis to the hollow cylinder specimens, has been used to study the properties of hydraulic fracturing for compacted cohesive soil under seepage force.

该仪器可严格控制中空园柱试件的边界受力条件及在垂直方向对试件施加拉力或压力。通过这种仪器进行了在渗水力作用下压实粘性土的水力劈裂性能研究。

Furthermore, the relationship between the boundary layers of the Cl~-and the brilliant blue in sand soil and light loam soil could be derived, which will provide an idea to use the brilliant blue dye to indicate the boundary layers of the non-reactive solutes.

两者边界层之间转换关系的求得，为应用亮兰染色剂准确指示非反应性溶质迁移边界层成为可能提供了一条思路。
