| 1 | Oil shale resources in China and their utilization显示文摘The unconventional oil and gas resources presented in oil shales have meant these potential sources of hydrocarbons,which has become a research focus. China contains abundant oil shale resources,ranking fourth in the world,with ca. 7 254. 48 × 10~8 t within 24 provinces,including 48 basins and 81 oil shale deposits. About 48% of the total oil shale resources are concentrated in the eastern resource region,with a further 22% in the central resource region. 65% of the total quantity of oil shale resources is present at depths of 0-500 m,with 17% of the total resources being defined as high-quality oil shales yielding more than 10% oil by weight.Chinese oil shale resources are generally hosted by Mesozoic sediments that account for 78% of the total resources. In terms of the geographical distribution of these resources,some 45% are located in plain regions,and different oil shale basins have various characteristics. The oil shale resources in China represent a highly prospective future source of hydrocarbons. These resources having potential use not only in power generation and oil refining but also in agriculture,metal and chemical productions,and environmental protection. | XU Zhi ZHU Jianwei DONG Qingshui SUN Pingchang | 2016 | Global Geology2016，19，1： | 2 |

| 3 | A Comparative Geochemistry Study of Several Oil Shale-Bearing Intervals in the Paleogene Huadian Formation,Huadian Basin,Northeast China显示文摘The Huadian Basin is an oil shale-bearing basin located in northeastern China.Thirteen oil shale layers deposited in this basin,and the characteristics of oil shale are different among these oil shale layers.Based on the core observation and microscope identification,using the organic and inorganic data from borehole HD3 and outcrops,the formation conditions of different grade oil shale have been evaluated.Based on measuring oil yield(OY in short)of an oil shale to determine its grade,this paper classifies the oil shale as high grade(OY≥10%),medium grade(10%>OY≥5%)and low grade(5%>OY≥3.5%).The high grade oil shale is mainly in brown or dark brown,and the bulk density ranges from 1.59 to 1.81 g/cm^3.The results of X-ray diffraction indicate the content of carbonate minerals is 28.0%.The HI(hydrogen index)-Tmax,HI-OI(oxygen index)and S_2-TOC(total organic carbon)diagrams indicate the kerogen types are I and II1.The high grade oil shale generally formed in the relatively arid paleoclimate,deposited in the brackish water,dysoxic environment,when the bioprodctivity is extremely high,and the information is mainly from the inorganic parameters diagrams of chemical index of alteration(CIA),Sr/Ba and V/(V+Ni).The medium grade oil shale mainly shows grey-black or black-brown color and the bulk density ranges from 1.87 to 2.08 g/cm^3.The average content of carbonate minerals is 16.4%,far less than high grade oil shale and the kerogen type is mainly II1.The inorganic parameters diagrams reflect the medium grade oil shale generally formed in the less humid paleoclimate,deposited in the brackish water,dysoxic to anoxic environment,when the bioproductivity is medium.The color of low grade oil shale is major in grey-black or dark grey and the bulk density ranges from 2.00 to 2.15 g/cm^3.The average content of carbonate minerals is sharply decreased and the kerogen type is mainly II1.The inorganic parameters diagrams indicate the low grade oil shale generally formed in the relatively humid paleoclimate,deposited in the freshwater to brackish water,anoxic environment,when the bioproductivity is relatively low.Comprehensive study suggest the increasing precipitation caused by a relatively humid paleoclimate resulted in decreasing oxygen concentration and salinity in the bottom water,restrained the salinity stratification,and tended to form the low grade oil shale.The strong evaporation leading to relatively arid paleoclimate resulted in increasing oxygen concentration and salinity in the bottom water,and promoted the salinity stratification.The area with well preservation conditions caused by the relative high sedimentary rate and salinity stratification are favorable to high grade oil shale deposit.In summary,the bioproductivity and the paleoclimate are the main factors controlling the oil shale grade in the Huadian Basin,when the bioproductivity is relatively high and the paleoclimate is relatively arid,it is prone to form the high grade oil shale.However the low grade oil shale developed in the low bioproductivity and relatively humid paleoclimate. | Yu Song Zhaojun Liu Pingchang Sun Qingtao Meng Rong Liu | 2017 | Journal of Earth Science2017，28，4： | 1 |

| 9 | Identification and Treatment of Swine Influenza and Common Cold in Veterinary Clinic显示文摘[Objective] The paper was to investigate the differentiation and treatment of swine influenza and common cold in veterinary clinic.[Method] The clinical data of diseased pigs from May 2017 to May 2018 were analyzed retrospectively to explore the clinical treatment methods for swine influenza and common cold, and the effectiveness and accuracy of clinical diagnosis was further improved. [Result] Through in-depth analysis of test results, we obtained a comprehensive understanding of the main causes of swine influenza and common cold, and found that the causes in-cluded improper breeding management of pigs, nutrition of pigs and lack of immunity of newborn pigs. [Conclusion] Analysis of the causes of swine influenza and common cold and suggestion of targeted clinical treatment measures will reduce the incidence of swine disease, and promote the vet-erinary clinical treatment effect of swine influenza and common cold. | Yi Pingchang Li Lili Li Guoping | 2018 | Animal Husbandry and Feed Science2018，10，5： | 0 |
| 10 | Coal-bearing strata sequence stratigraphy of Paleogene Meihe Formation,Meihe Basin,NE China显示文摘The Meihe Basin is an important Paleogene coal-bearing basin located in the Dunhua-Mishan Fault Zone,northeastern China.Based on a comprehensive study of well logs,seismic profiles,cores and rock geochemical properties,the coal distribution,paleoenvironment evolution within a sequence stratigraphic framework and the accumulation model to explain how coal seams developed in small fault basin were discussed in detail.Three-third-order sequences were identified in the Paleogene Meihe Formation of Meihe Basin and the two coal-bearing sequences are the Lower Coalbearing Member of Sequence I and the Upper Coal-bearing Member of Sequence III.All three types of system tracts are developed in both sequences,i.e.,the lowstand systems tract(LST),the transgressive systems tract(TST),and the highstand systems tract(HST).In LST of Sequence I,fan delta plain marsh is the main coal accumulating environment where coal seams are thin,discontinuous and therefore uneconomic for mining,and it is the same with all coal seams developed in Sequence III.While in TST and HST of Sequence I,lake swamp is the main sedimentary environment where coal seams are thick,continuous,widely distributed,and thus economically attractive for mining.In the study area,the nice thick economical coal seams are usually developed in an ideal stable depositional environment where organic matter accommodation space grows at a balanced rate with peat,in other words,free of sediment input or channel migration.The key findings of this study could provide guidance for the exploration of coal seams in the Meihe Basin and other similar basins. | Yueyue Bai Qingtian Lii Zhaojun Liu Pingchang Sun Rong Liu Shuqing Yao | 2021 | International Journal of Coal Science & Technology2021，8，4： | 0 |
| 11 | Prevention and Treatment Strategy of Highly Pathogenic Porcine Reproductive and Respiratory Syndrome(HP-PRRS)显示文摘At the present stage, the social economy in China has developed by leaps and bounds. China's pig industry has been well developed un-der the background of this era. However, the number of pig diseases increases due to the influence of many factors, and highly pathogenic porcine reproductive and respiratory syndrome(HP-PRRS) is one of the very common diseases, causing growing mortality rate of pigs. The disease increases the economic loss of pig industry to a large extent, and brings difficulties in prevention and control of pig diseases. The staff must analyze and sum-marize the basic characteristics of pig diseases, and combine some practical problems in prevention and control of pig disease to find effective mea-sures. The scope and scale of pig production in different parts of China have been continuously expanded under the background of further develop-ment of pig industry in the new era. But for pig production, pig disease has been a problem that delays its further development. Related personnel must analyze and summarize the status quo of HP-PRRS, to find effective prevention measures and strategy. | Yi Pingchang Li Lili Li Guoping | 2019 | Animal Husbandry and Feed Science2019，11，1： | 0 |
