CNTs can be categorized as single-walled (SWNTs) and multi-walled (MWNTs) nanotubes, where the former are the fundamental cylindrical structure and the latter are the layer-by-layer junction of two or more coaxial cylinders [1].
This could be due to the CNTs belong to the long tube structure and the properties of the fibrillated polymer are similar, as a result the stress can be transmitted between the two phases, thereby increasing the rigidity of the composite.

The liquid water transport in the inner structure of tested plasters we characterized using the water sorptivity concept based on 1-D free water intake experiment.
This we assign to the change of inner structure of plasters caused by the inert PCM particles that partially retarded formation of cement-lime matrix.

Researchers have also attempted to modify the structure of chitosan in order to obtain highly efficient adsorbents [3, 6].
The SEM image of paddy crab shell chitosan sample has a uniform and homogeneous structure.
On the other hand, the SEM image of polyaniline shows granular structure with small particle size.

Polyvinyl chloride (PVC) is a versatile polymer with a wide range of applications, and it is commonly used in the footwear industry The chemical structure of PVC is represented as (-CH2-CHCl-)n, where n is the number of repeating units in the polymer chain.
The specific chemical structure can vary depending on the components used in the blend.
The outsole, vital for the shoe's bottom structure, heavily relies on polymers, constituting 14% of the cost with materials like EVA, PVC, and thermoplastic rubber.

This is because glycerin has a flexible structure.

Single B2 structure is identified in the HF Ti50Ni47Fe3 alloy.
The amount of the preferred variants goes up with the increase of the deformation rate, which results in stabilization of the martensitic structure owing to a lower free energy of the singe variant compared with the mixed ones.

The structure and process of the prevailing stainless steel stamping well pumps are very different from casting pumps [1].
The efficiency of pumps is jointly determined by impellers and guide vanes, so the regression test integrates the structure parameters of impellers and guide vanes and selects the following four geometric parameters as test factors: impeller outlet angle β2 = 22.5°～37.5°, impeller inlet angle Δβ1 = -5°～5°, impeller outlet width b2 = 7.5～10.5mm, guide vane inlet width B3 = 9～11mm.
In addition, since the structure of the model pump is a cylindrical impeller with the common return guide vane, while compared to the same size of other pumps which are using distorted impeller with vaned diffuser, the production process of this stamping well pump is greatly simplified, and the cost reduces significantly.

., simple structure, great nonlinear approximation ability, fast convergence and global convergence, RBF neural network has been widely used in fields of intelligent control, system optimization, signal and information processing, pattern recognition etc. [1].
In addition, to determine network structure, m as cluster number must be predefined, the accurate degree of selecting m directly affects network classify performance.
The Basic Principle of RBF Neural Network Modeling Based on K-means Clustering RBF neural networks is a three-layered feedforward network from the structure, with an input layer, an output layer and a hidden layer, as it’s shown in Fig 1.
