The latter focus is a local point’s material removal rate in CMP.
A lot of experiments under the prediction of the Preston equation show the CMP process of SiO2 and W is a better precision, but in the prediction of other materials, the theoretical and actual results in CMP created large deviation.
Based on continuous media indentation- scratch’s material removal mechanism, Luo [3] and others proposed a more comprehensive materials removal model according to the contact mechanics and statistical theory.

The brightest trait of the degenerated virtual laminated element is virtual lamination, so the calculation of the stiffness matrix can be divided into different blocks and different materials, and the blocks with no material are virtual blocks, the stiffness of which are set to be zero.
Hence, since an element could contain multiple materials or even no material, the work is much easier when we separate the structure into elements, especially for complicated structures such as box girder, the number of elements can be remarkably reduced.
The formula to calculate the stiffness matrix of an element containing various materials is as follows: (2) In the formula, is the number of material types, is the Jocobi determinant of the coordinate transverse matrix for the very block.

Introduction Laser cladding is a process of depositing additive materials on a substrate as a special treatment by using the laser beam as a heat source.
The thermal properties of materials are temperature-dependent [8].

Details of the validation of this constitutive relation for both materials are shown in Fig.7.
A very good repeatability of the experimental techniques used in dynamic characterization of these materials was shown.
These data can contribute to the improvement of the current understanding of the non linear behaviour of materials by taking into account the effect of the rate of loading and in the knowledge of the materials response to dynamic loadings.

It is also expected to be applied as next-generation semiconductor materials in the industry application like transistors[8,9] because of its unique tunable electronic structure, high carrier mobility.
In addition, similar to graphene, 2-D MoS2 nanosheet can be combined with other functional materials to synthesize composite nanomaterials with special functions or functions, further expanding the application of 2-D nanomaterials[10].

In catalytic and sorption processes, the porous structure of materials plays a large role [9], so studies aimed at improving their structural-surface characteristics, such as specific surface (SBET) and pore volume (VBJH), are relevant.
Supercritical drying is a promising method for obtaining materials with a developed specific surface area.
