2.Abstract: Sewage sludge briquette made of 2%(dry basis) sewage sludge,0.3%white earth, and coal powder was studied under conditions of briquette similar to modeling and gasificaition for briquette on ammonia synthesis.Briguette with white earth was taken as a reference.The results showed that rate of gasification of sewage sludge briquette was 50%higher than that of briquette of white earth at 1100℃.Ash melting point of sewage sludge briquette reached 1440℃ which satisfied the requirement of gasification of ammonia synthesis.Results showed that no pollution took place in these processes,and the gas generated can meet the demand of ammonia synthesis.
3.The max paleogeothermal values of stratum were reached in the early-Cretaceous period according to the simulation result of basin thermal history,the period of tectonic heat event happened in the early-Cretaceous period is the main formation period of gas in coal stratum of Palaeozoic era,it is also the formation period of metal uranium in Dongsheng area.
4.The palaeogeographic research indicate that the palaeogeographic outline of the study area recorded the evolution from a sedimentary basin in which the shallow-water carbonate platform sediments and deep-water terrigenous clastic submarine fan developed from southeast to northwest and northeast during the Late Triassic through a submarine sheet-like model composed of deep-water sandy turbidite and fine-grained turbidite during the Early Jurassic to a terrigenous clastic barrier coast during the Middle and Late Jurassic and finally to the coal-bearing delta sediments during the Late Cretaceous.
5.Twenty white cocoon silkworm varieties of European race maintained at the Sericul-tural Research Institute were investigated for the presence of yellow inhibitors. The domi-nant yellow inhibitor (I) was found to be present in the varieties of Ou - 17,Ou - 18,Ou -19,Fa - 50B, Xinnong Oubai, Sulian - 1, Bagdad, AN525 and Asage. In addition, the re-cessive sooty white coccon gene, Is, was observed in Sulian - 1 and Bagdad.
6.Abstract: The resource characteristics such as the composition,texture,structure and the prospects of industrial utilizations included white carbon black,AlC13,4A zeolite,Al-Si alloy and rubber filler of coal-series kaolinite in Huainan and Huaibei mining area were introduced.
7.Based on comprehensive analysis of the outcrops and interpretation of seismic data in this area,six detachments are identified,which are the Middle Permian Lucaogou and Hongyanchi Formations,the Lower Jurassic Badaowan Formation,the Middle Jurassic Xishanyao Formation,the Cretaceous Tugulu Group,the Palaeocene Anjihaihe Formation and the Neocene Taxihe Formation from the deep to the shallow.
8.The study of buried history,geothermal history,source-reservoir-seal assemblage and hydrocarbon-expulsion history of the depression showed that the pools generated by the coal-related source rocks in the Upper Paleozoic were formed in two stages of the Late Mesozoic and the Palaeogene periods to present.
9.Strong acid in pH0.80～1.32 is first recognized and determined from the “white clay” for Meishan section A and B. The finding as more substantial evidence strongly supports the suggestion that a marine acidification event could occur at the span of the Permian-Triassic boundary, 251 million years ago, in our Earth history.
