On the basis of the summing up of the experiment, this paper discusses the range of constitutent, addition of quantity of inoculant and nodulizer and their effect rule and the control on compose nature when producing medium-manganese ductile iron with Lufeng pig iron.

This experiment studied the factors that affected the s ur vival rate of cuttage and reproduce of Phlox subulata.

The effect of different additives,seeds and introduction methods on in-situ growth Columnar Crystals of alumina was summarized.

By introducing ZrO2 micron powder into the thermit and through thermit combustion, liquid-liquid separation of metal/ceramics and crystal in-situ growth of eutectic reaction, self-toughening composite ceramics with in-situ growing nano-micron fibers were fabricated.

The preparation process of structure and conducting channel in carbon nanotube field effect transistor (CNTFET) was reviewed, including AFM manipulation, CVD in-situ growth of single-walled carbon nanotube (SWCNT),AC dielectrophoresis and L-B manipulation, etc.
