In the space, it is easy to introduce various forms of interference and noise, affect the reliability of power supply directly, thereby affecting the OCO's technical performance.
The shell temperature must be strictly limited within the expected temperature.It is generally recommended that range from 30% to 70% of the rated power is appropriate (specific ratio of the size and other factors), DC/DC module has a good performance and adequate reliable in this range.
Circuit design should take reasonable ground design as well as additional filters to meet the requirements of noise conduction.A chassis with good electrical properties can reduce electromagnetic radiation, the intensity of the electromagnetic interference can be attenuated to the original one percent to more than one millionth usually [7] .
First determine the circuit allows maximum rated current, select the the corresponding derating factor, and then, depending on the type of fuse, rated current value multiplied by the derating factor S is not less than the maximum rated operating current, and then according to the selected fuse Specifications table, choose a slightly larger than the current specifications.

In the study, thermal efficiency in MIG welding of aluminum alloy with longitudinal magnetic field was analyzed, as well as softening behavior of heat-affected zone (HAZ) and base metal were investigated.
The applications of electromagnetic field in welding is a new developed technology in recent years, by which the welding arc shape, melting droplet transition and crystallization process of liquid metal in the molten pool are influenced through additional magnetic field, accordingly refining weld crystal organization and improving mechanical properties [2]. 
DuPont had demonstrated that melting efficiency can be predicted from the welding parameters and material properties by the equation 5 [9]
(a) I=0A; (b) I=10A; (c) I=20A; (d) I=25A Fig.4 Cross-sectional area of fusion zone under different exciting current intensity Softening Behavior with Additional Magnetic Field.Microstructure and properties of base metal changed owing to the heat input decreasing and the redistribution of heat flux on the surface of base metal under the action of magnetic field.
But when exciting current intensity continued to increase, microstructure and mechanical property of HAZ did not change obviously.

The effects of nitrogen doping on coating morphology, physical properties, and FA degradation rates were experimentally determined.
Dopants affect the UV–vis spectra by inhibiting recombination of electron–hole pairs, here especially for the N–doped specimens.
This form Ti–O–N linkages, reducing the band gap energy beneficially for the photocatalytic properties of 40N/SnO2/TiO2 films.
According to prior reports, various factors affect the photoactivity of TiO2 photocatalysts, including crystallinity, grain size, specific surface area, surface morphology and surface state (surface OH radicals), and these factors are not independent but closely related to each other [6].
Nitrogen doping of SnO2/TiO2 composite films affect surface smoothness, crystallite size, and band gap energy of the films.

All these factors promote the polarization of public opinion transmissions in a self-media network.
Each time a popular topic is accepted, the energy of the self-media user can be increased, which has the property of diminishing returns.
This is because the initial temperature and probability parameter are the indirect action factors and the direct action factors, respectively, of the transmission probability, which can keep the transmission probability from obtaining a larger value for a long time and prolong the propagation time and range of the event.
This section takes the "Liu Guo Liang's resignation event" as an example in order to study the relationship between these two metrics and the influencing factors

An explanation for the observed influence of structure and dispersion factors on the melting parameters has been proposed on the basis of X-ray diffraction data, electron microscopy, and model calculations.
It is known that varying the size of structural units (crystallites) of compact metals, as well as particles of metal powders, allows to change the electrophysical, mechanical, optical, physico-chemical properties of such materials.

They concluded that several factors do affect the maximum adsorption capacity and reaction kinetics such as the nature of the divalent and trivalent cations, their relative ratio, and the preparation method.
The equilibrium time is considered one of the important factors that affect the cost and applicability of the adsorption process.

Modeling of test platform was built to study the mechanical structure in theory.
However, the gear system displays undesirable characteristics such as the backlash, which becomes a mechanical imperfection.
Design of key part The platform uses a flexible coupling which allows a certain deviation in the case which does not affect the vibration and the life of the entire connection.
Gear meshing Fig.8 Total deformation Compared with the property of the material, the custom-made couplings can meet requirements.
Analysis static structure The backlash caused by shape-changed of the gears is one of the main influence factors, so it is important to analysis the static structure to find out the maximum deformation, equivalent (von-Mises) stress and equivalent elastic strain.

The dynamic PSO modifies the inertia weight, learning coefficients and two independent random sequences which affect the convergence capability and solution quality, in order to improve the performance of the standard PSO algorithm.
While the motor parameters change with the external factors, these changes are not only related to motor temperature, but also related to motor operating condition.
For example, RLS algorithm is complex and the identification result accuracy is lower; EKF algorithm design and the objective function are difficult to determine, the operating time is longer, and easily affected by noise; MRAS can only identify rotor time constant or rotor resistance In recent years, many scholars apply intelligent optimization algorithm to asynchronous motor parameter identification.

Introduction As we known, wood is a viscoelastic material and therefore its mechanical properties are affected by temperature [1].
Based on temperatures, time-scale is also an important factor influencing the strength properties.
The effect of temperature on the mechanical properties of wood can be categorized into two classes: reversible effects, which refer to transient changes in mechanical properties at temperatures below 100ºC, and irreversible effects, which are brought about by the thermal degradation of wood constituents at high temperatures.
