Fig. 1 Casting set up using a vacuum centrifugal casting machine.
Table 1 shows the maximum thickness of α case obtained after oxidation.
In Table 1, α case in the forged samples was thicker than in the cast ones for each alloy.

According to Figure 1 and Table 1, the international energy market would undergo huge reforms in the early of 21st century and the total output of coal sources declines slightly.
The output point strength of node 1 is defined as (1) And the input point strength of node 1 is defined as (2) In this equation, it implies the weight of node i to node j in year t.
If the value is 1, then it shows all the adjacent nodes are linked with node 1.

As shown in figure 1:
Fig. 1 Parallel sensor structure based on Stewart platform
Relations between the sensor receiving strength and the output strength are:

Keywords: sail-assisted ship; simulation; main engine; turbocharger; matching.
Researches showed that, fuel oil costs would be reduced by 30-40% on some sail-assisted ships [1,2].
The main parameters of the engine and turbocharger were shown in table 1 [4,5].

Other details of the processing conditions to get these proportions are given in Table 1.
If 𝑏2 = -1 then the profile is spherical, 𝑏2 = 0 then its parabolic, 𝑏2 > 0 then profile is hyperbolic, −1 < 𝑏2 < 0 then the profile is prolate spheroid, 𝑏2 < −1 then its oblate spheroid.

Proximate analysis, caking index and gelatin layer index for the coals and CP were referring to the standard GB/T 212-2001, GB/T 5447-1997 and GB/T 479-2000, respectively.
The technical analysis of the coals and CP was shown in Table 1 and the particle size distribution for CP was shown in Table 2.
Coke samples ground between 1 to 3 mm were mounted in epoxy resin with the proportion 1:2, then photographed the interfaces by means of oil immersion objective of polarized microscope fitted with crossed polar and λ/2 retarder plate at 200 times.
It was presented from Fig.1 that the M25 index decreased, and the M10 index increased with the particle size interval of CP increasing.
