Introduction Ti-6Al-4V alloy has been widely applied in many industrial fields because of its high strength, low density and good corrosion resistance [1].
XRD patterns of thermally oxidized surfaces before and after vacuum diffusion are illustrated in Fig. 1.

Particularly important is the last parameter, since it is closely related to the oscillations of the tension in the yarn [1,2].

Electrochemical Model of DMFC The working principle of direct methanol fuel cell is shown in figure1[1]: At the anode, Methanol reacts with water to generate carbon dioxide, protons and electrons according to the anode reaction expressed by (1).
The overall reaction equation of the fuel cell is shown in the ( 3) Anode Reaction:: (1) Cathode Reaction: (2) The Overall Reaction: (3) B.
Figure7 Methanol fuel cell characteristics at different temperatures Figure 8: Methanol fuel cell characteristics at different concentrations According to the figure 8 under a certain output voltage, the fuel cell has the maximum output voltage when the concentration of methanol is 2.0 mol/ L−1.
A conclusion should be drawled that the concentration should not be more than 2 mol/ L−1 because a higher concentration can lead to lower fuel utilization efficiency and the lower Faradic efficiency[10].

Then the average weighted coefficient is taking into calculation in order to review the status of research target[1].
For instance, in the index weighted matrix X1=（x1,x2,x3,）, x1+x2+x3=1.
