Due to the dielectric constant error of the dielectric substrate and the loss of the coaxial probes, as well as the dielectric loss introduced in the process of material processing, there is a certain error between the simulation results and actual measurement results.

Many more percolation pathways form for enhanced conductivity, but the materials become to be porous and weak [3].
As a result, composite plate materials with high graphite content are extremely brittle, and have poor gas barrier properties.

As the core of UHV grid, UHV substation has the features including the construction area is large, process is complex, work sites are scattered, the personnel and materials are many and security requires high level.
The resources at the construction site are various, including materials, vehicles, mechanical equipment, and constructors, etc.
As the construction area is big and scattered, the positions of personnel, equipment and materials change frequently, it will waste a lot of precious time and resources to check the resources and positions.

Introduction In recent years, periodic microstructures play an increasingly important role in many fields, such as high-precision measurement sensor, high-density storage of nano-gratings, bionic multifunctional superhydrophobic surfaces, artificial materials with negative refractive index, super-resolution nano-photonic crystals, etc.[1,2].
Nickel, as an important alloying material, is generally used as the mold for microfluidic chips.
