Feldman et al[2] also considered this problem and gives the coding algorithm in small finite fields by leaving a small amount of bandwidth, There is a major problem is the use of random network coding, security coding probability is very low.

Jie Chen et al.[8] studied that the electrical resistivity of composites decreases slightly at the CB content smaller than 3.0 wt% and later decrease apparently at the CB content higher than 3.0 wt%.
Xin Wen et al.[10] have reported that the thermal decomposition temperature for PP/CB nanocomposites shifted significantly to a higher temperature range than for neat PP which indicate an improvement of thermal stability.

During 1990, El-Shakery et al. [5] conducts the analysis and design of inline conveyors driven by linkages.
In 2005, Ting et al. [6] proposed an inline conveyor driven by a bimorph piezoelectric actuator, and its dynamic modelling, driving control circuit design, motion trajectory analysis, and optimal transport feed are examined.

According to the theory of Helmholtz on electric double layer and the theory on extended electric double layer developed by Stern et al[7],as the difference between the adsorption coefficient of positive and negative ions existing in oil, the solid surface would be charged because of the adsorption of charges with opposite polarity in oil or the ionization of weak chemical bonds on the solid surface due to the action of solvent.
Gavis et al J.
Brozostek et al from British thought that, the polarity of charges depended on the ageing degree of oil.
As the oil flowing through the solid insulation of the winding, it would be electrified.
Therefore, if the solid material was not changed, then the electric polarity of charges in oil would not change too.

Cerpa et al., have reported on an the optimized nitric acid oxidation protocol for commercial single-walled carbon nanotubes during 24 and 48 h oxidation times [7].

[22].
