The cuticle exists as the separable outer boundary and consists of a layer of wax and pectin materials that appears to be structureless. 可以区分开来的外部周界是表皮层，由无定形组织的蜡质和果胶构成。
Compacted structureless clay soils can be flocculated by the addition of neutral salts, particularly of calcium. 紧密的无结构粘土可以由于中性盐尤其是钙盐的添加而聚集。
A new method of structureless road detection based on colorful image was presented. 摘要提出一种基于彩色图像的非结构化道路检测算法。
Industrial robots have been widely applied in automation manufacture fields for their high repeated precision in structureless and complicated workspace. 摘要工业机器人以其高重复精度，适应于复杂工作空间而广泛应用于工业自动化生产领域。
In addition, electrons are structureless elementary particles, whereas protons and neutrons are themselves complex bundles of particles called quarks and gluons. 此外，电子是没有结构（点状）的基本粒子，而质子与中子则有复杂的结构，它们是由夸克（quark）和胶子（gluon）所组成。
Neutron transfer channels of which transfer Q values are positive make the barrier distribution flat and almost structureless and extend to very low energies. 转移道的耦合,特别是转移Q值为正的中子转移道的耦合使得熔合势垒分布变得扁平且向低能展宽,这会导致垒下熔合截面大大增强。
