Background of Commercialized BMGs and Novel-Type Nanocrystalline Alloys BMGs are a new class of metallic materials with medium-range ordered atomic configurations.
Zr-Based BMGs Although BMGs such as Pd-Au-Si and Pt-Ni-P [13] were found in the late 1960s, two main factors hindered the widespread exploration among material science researchers: the reliance of noble metals and the limited preparation method.
Nowadays, it has been recognized that these Fe-based materials have opened up new academic and engineering fields called with soft magnetic component (SMC).
For instance, their SMC materials, which are mainly composed of glassy alloy powders covered with resin and oxide mixture, exhibit saturation magnetic flux density of 1.2 - 1.3 T, coercivity of 1.9 – 3.8 A/m, permeability of 60 up to 1 MHz, core loss of about 200 kW/m3 at 100 kHz and 0.1 T and have been used in various fields such as SMC materials and RFI sheets in smartphones, PCs and automobile AV equipment devices, car navigation system etc.

Prediction model of road vehicle noise which could be regarded as discontinuous linear sound was as following: (1) Type: Leqi—equivalent continuous A-weighted sound pressure level of i type vehicle LAi—sound pressure level of i type vehicle radiated noise at reference point; dB T—evaluation time, generally for 1h; Ni —traffic flow of i type vehicle, vehicle / h; Vi —vehicle speed, km/h; ro—distance from reference point to lane; generally for 7.5 meter; r —distance from precalculated position to lane; α—attenuation factor related to absorption characteristics of mulching material, generally for 0.5 in rural area; △S—additional attenuation due to obstructions such as buildings, terrain, embankments, cuttings during noise transmission, dB 2)Equivalent continuous A-weighted sound pressure level of nighttime If the traffic volume of nighttime was less than 300Veh/h, “(2)”should be applied for noise prediction, otherwise, “(1)”used[3]

Based on the theory of dissipative structure, the result of human actions for changing the natural environment and creating artificial systems, such as to raise potential energy of a system, to increase pressure in a vessel, to make artificial materials, to separate components from a mixed system, is to import negative entropy to these systems to form ordered and stable structural systems, which all are systems far from equilibrium state.
Information system Control the machine itself and the input and output of energy; material and information by the transfer of information (through cables).
