The morphology of sulfide affects the cutting and mechanical properties of the steel significantly.
The addition Ca can optimize the morphology and distribution of sulfides, thereby reducing the effect on the mechanical properties of steels [2-4].
And the segregation of sulfide induced eutectoid ferrite to separate out along the grain boundaries.[5-8] 2.2 Effect of rolling temperature on the morphology of sulfide and the mechanical properties Rolling temperature affected not only the microstructure, such as grain size and interlamellar spacing of pearlite, but also the morphology of sulfide in the 30MnVS rods.
Compared the mechanical properties of the rods(Table 3), we found that the mechanical properties of the 30MnVS rods rolled at 970/870℃ and 1020/905℃ were quite similar, as the morphology and distribution of sulfides.

Density is an important indicator of wood’s properties, which directly impact on the physical, mechanical and processing and using performance.
Wood as a load-bearing structure of the material, its quality depends mainly on its density, which is closely related with its mechanical properties, hardness, abrasion resistance, and so on.
Since the absorption intensity of near-infrared spectral is weak, the sample spectrum is susceptible to the sample state, the measurement conditions and other factors.
Therefore, before building spectral prediction model, the spectral data need to be preprocessing to enhance the effective information of spectrum, eliminating the interference of various factors, improved spectral prediction accuracy.
Conclusion Wood density is one of the important properties of wood, using near-infrared spectroscopy technology can predict it quickly.
