One-staged forming of porous C/C composites as well as volume fraction control of pores were realized, based on thermophysical property analysis and proportioning design of raw materials.Short fiber reinforced C/C-SiC composites with high densification and low content of residual Si were prepared by hot-pressing-infiltration two-step method at low

Combining ability has been proved to be a method to identify and select the parents and hybrids for increased production through the exploitation of heterosis.The exploitation of heterosis would be useful if suitable hybrids are produced for low yielding environmental conditions of littoral sandy soil.Combining ability effects for early germination
