Fig. 1 Calculated opal colors sequenced by h0 Fig. 2 Calculated opal colors sequenced by L* L-3-1 Fig. 3 Australia blue opal L-3 Fig. 4 Microstructure of L-3 under SEM Fig. 5 Microstructure of L-3 under SEM Results Color Analysis.
To avoid impact from opal luster and the subjectivity of the human eye, 33 pieces opals were classified by hue (h0) and lightness (L*) respectively, see Figs 1 and 2.
Transfer Table 1 color parameters from standard light source D65 to C, then calculated dominant wavelength of each color.
Both SEM and AFM images reveal the SiO2 packing of testing area L-3-1 of sample L-3, and the image of SEM can show the rule packing of opal more obviously, see figure 6 and figure 7.

Introduction Valves are one of the most important parts in ultra-high pressure systems, where the reliability, safety, working efficiency and service life of valves directly influence the working of the entire system [1].
It is deemed that the entire cylinder consists of the following two parts: elastic range and plastic range, as indicated in Fig 1.
Fig4 Curve of change of maximum stress with autofrettage pressure when valve body is working Fig3 Diagram of Valve Body Critical Yield Pressure Fig6 Change of Maximum Residual Equivalent Stress after Autofrettage Pressure is Discharged Fig5 Change of Elasto Plasticity Radius of Valve Body at Autofrettage Pressure Conclusion (1) When determining the maximum value of autofrettage pressure, the maximum pressure, at which reverse yield does not happen, and the complete yield pressure shall be taken into consideration, with the smaller value of the two taken after comparison and analysis.
