Experiments shows that the chlorine in the PVC、PVDC、HCB could be completely dechlorinated when they were grinded in the ball mill. Furthermore, Zn2OCl_2.2H_2O, Zn_5(OH)_8 Cl_2.H_2O,ClO_2 are found through XRD,IR etc, we also found out that the production contained elementary substance of black C.
Absorption of visible light by Fe 2+ -Ti 4+ at 565 nm is the factor causing beautiful blue color, while black color results from Fe 3+ absorbing visible light at 442 nm. Coloring experiments were carried out to remove Fe 3+ as well as retain and add Fe 2+ and Ti 4+ , which prove to be successful.
Methods Using minisatellite variant repeat mapping polymerase chain reaction (MVR PCR), automated fluorescence detection, DNA sequence analysis, the authors studied the locus DYF155S1 of two chimpanzee and 10 human subjects from each of the following 8 groups: Northern China Hans, Southern China Hans, the Zang (Tibetan) nationality, the Uighur nationality, Japanese, Korean, Black African, White African.
The frequency of C6*A in Mongoloid populations is usually lower than 0.5, while that of black people ranges between 0.5 and 0.6 and that of white people is higher than 0.6. The other difference between Caucasian and Mongoloid is that the former has very few C6*B2 while the frequency of C6*B2 in the latter ranges from 0.03 to 0.07.
