Mitochondrial 16S rRNA gene and COⅠ gene fragments were amplified and sequenced from 4 wild populations of Portunus trituberculatus. Respectively, 524bp and 658bp long partial gene fragments of the 16S rRNA gene and the COⅠ gene were obtained. A high percentage of A+T base composition in the two sequences was observed, which was similar to the results of studies on drosophila, shrimp, crab and other invertebrates.

Meanwhile, the surface layer gets fine crystal grain with dispersive and homogeneous distribution of WC grains and Co binder from rapid melting and resolidification during HIPIB irradiation. Minimizing the mean free path in Co binder by decreasing the WC grain size leads to an increase in resistance to plastic deformation in the binder.

The major phase of both slags produced from air and CO/CO2 conditions were SiO2 and Fe2O3, which have much benefit to the encapsulation of heavy metals. The leaching concentration of zinc in CO/CO2 reducing condition is an order less than that in air oxidizing condition due to the higher vapored heavy metals in CO/CO2 reducing condition compared to that in air oxidizing condition. Furthermore, the leaching rate of heavy metals in both CO/CO2 and air conditions are almost the same.

Templating agent could not be sufficiently removed at temperature below 500℃, while temperature exceeding 600℃ might result in collapse of the framework. The conversion from Co(superscript 2+) to Co(superscript 2+) was a gradual time-consuming process. Calcination at 550℃ in a muffle furnace for 10 hours could remove the templating agent and bond water and give a satisfactory result.

By studying the inorganic CO〓 and helium isotopes in Yinggehai Basin, and investigating the Tertiary lithology and geothermal condition, combined with the results of thermal simulation test, it was suggested that inorganic CO〓 gas principally came from thermal decomposition of Tertiary calcareous shales and Pre-Tertiary carbonate under the burial depth of 6000m, approximately at a strata temperature of about 250℃.

The results indicate the mutual effect exists between the single coals, which could increase the maximum of thermal weight loss obviously and has a small effect on the temperature extent of the weight loss. The main pyrolysis production of coal is coke, but the main production of waste plastics is tar; the yield of water became decrease and the gas became increase by adding the waste plastics. And the CRI and CSR decreased with the ratio of waste plastics in coal. The main ingredients of tar from blend coal are aromatic hydrocarbon and alkane, while those of waste plastics are alkane and alkene. The result of co-coking with coal and waste plastics make the light tar and the aromatic hydrocarbon increase obviously. The combustible ingredient(CO、H2国产免费高潮流白浆A片99、CH4) of gas from co-coking with coal increase at different ratio; Co-coking with coal and waste plastics could increase the combustible ingredient and thermal value of gas.
