| 1 | Cracking conditions of crude oil under different geological environments显示文摘There are mainly 3 kinds of existing states of oil generating from source rocks,that is,dispersive liquid hydrocarbon inside of source rock,dispersive liquid hydrocarbon outside of source rock and concentrated liquid hydrocarbon outside of source rock.Because of the differences in thermal history and medium conditions around,and the interaction of organic and inorganic matter,the liquid hydrocarbon with 3 kinds of existing state has different cracking conditions.The gas generation dynamics experiments of crude oil matching different mediums indicate that the distribution of activation energy of methane changes a lot according to medium difference.The carbonate has a main influence on oil cracking conditions and can largely reduce its activation energy,which reflects the lower cracking temperature of crude oil.The mudstone takes a second place and the sandstone is the smallest.The catalytic cracking function to the oil of the carbonate,of the mudstone and of the sandstone changes weaken in turn.The corresponding Ro values of main gas generation period in different mediums are as follows:1.5%―3.8%with pure crude oil,1.2%―3.2%with dispersive crude oil in carbonate,1.3%~3.4% with dispersive crude oil in mudstone and 1.4%―3.6%with dispersive crude oil in sandstone.The influence of pressure to crude oil cracking is relatively complicated.In the low heating speed condition, pressure restrains the oil cracking and gas generation,but in the high heating speed condition,pressure has an indistinctive influence to the oil cracking and gas generation.Pressure also makes a different effort in different evolvement stage.Taking the middle and lower Cambrian source rocks in the Tarim Basin as an example,primary oil generating quantity is 2232.24×10 8 t,residual oil and oil cracking gas quantity is 806.21×10 8 t and 106.95×10 12 m 3 respectively. | ZHAO WenZhi,WANG ZhaoYun,ZHANG ShuiChang&WANG HongJun Research Institute of Petroleum Exploration&Development,PetroChina,Beijing 100083,China | 2008 | Science China Earth Sciences2008，51，S1： | 8 |
| 2 | Independent ore deposits of dispersed elements显示文摘EIGHT elements Ge, Ga, In, Tl, Re, Cd, Se and Te are usually referred to as dispersed elements. In the long past, there has been no report on independent ore deposits of dispersed elements at home andabroad. In recent years there have been continually discovered independent ore deposits of Ge, Tl, Cd,Se and Te in the southwestern part of China, which is a great breakthrough in the field of ore deposits.The discovery of dispersed element independent deposits indicates that the dispersed elements are of dispersion in nature, but, on the other hand, they can also be concentrated to form independent ore depositsunder favorable geological conditions, even to form superlarge ore deposits under certain geological conditions. Having being restrained by traditional ideas, people have not paid sufficient attention to thestudy of independent ore deposits of dispersed elements as they have little knowledge about the geochemical behavior of dispersed elements in the processes of their mobilization, transport and enrichment. | GAO Zhenmin, LI Chaoyang and YAO Linbo Institute of Geochemistry, Chinese Academy of Sciences, Guiyang 550002, China | 1999 | Chinese Science Bulletin1999，44，S2： | 3 |
| 3 | The hydrocarbon generation mechanism and the threestage type model of hydrocarbon generation for carbonate source rocks显示文摘The diagenetic mechanism and process of carbonate rocks, which is different to that of clastic rocks, decides the existence of different existing state organic matters in carbonate rocks. This has been verified by both the microscopic observation of organic petrology and the analysis of organic geochemistry of many samples. Based on the hydrous pyrolysis simulation experiment of the low-mature carbonate rocks, the contrasting study on the yield and their geochemistry characteristics of different existing state soluble organic matters of a series of various maturity samples shows that the different existing state organic matters make different contributions to hydrocarbon generation during every evolution state. So that, the hydrocarbon generation process of carbonate rocks can be summarized as the following three stages; the first is the direct degradation of biogenic bitumen macromolecules during the immature stage, the second is the thermal degradation of a large amount of kerogen at the mature stage, | 王兆云 程克明 | 1997 | Science China Earth Sciences1997，40，3： | 2 |

| 5 | Estimating the resistance of aging service-proven bridges with a Gamma process-based deterioration model显示文摘The environmental or anthropogenic factors, to which the in-service bridges are subjected,are responsible for the reduction of bridge performance, and finally lead to great service risk for bridges and increase the probability of substantial economic losses. Probabilitybased estimate of bridge resistance is an essential indicator for the bridge condition evaluation and for optimization of bridge maintenance/repair decisions. It places an emphasis on the proper probabilistic models of structural properties and assessment methods. Making full use of historical service load information may improve the accuracy of bridge performance assessment with reduced epistemic uncertainty for existing aging bridges. In to-date analyses to update the bridge resistance with past service information,the models of resistance deterioration have been assumed as either deterministic or fully correlated, which may differ significantly from the realistic case. With this regard, this paper proposes a novel method for updating the resistance of service-proven bridges with a realistic deterioration model. The Gamma stochastic process has been suggested in the literature to describe the probabilistic behavior of structural time-dependent resistance and thus is adopted in this paper. An illustrative bridge is presented to demonstrate the applicability of the proposed method. Parametric examples are conducted to investigate the role of resistance deterioration model in the updated estimate of bridge resistance with historical service information. | Cao Wang Kairui Feng Long Zhang Aming Zou | 2019 | Journal of Traffic and Transportation Engineering(English Edition)2019，6，1： | 1 |
| 6 | Development and Application of Evaluation Index System and Model for Existing Building Green-Retrofitting显示文摘This paper establishes an evaluation index system for existing building green-retrofitting considering different building majors. The weights of indicators at different levels were determined by using decision-making analytic hierarchy process. According to fuzzy mathematics theory, indicators at different levels were taken into an evaluation factor set while three-star level, two-star level, one-star level and unqualified level were taken as the comment set to develop a fuzzy comprehensive evaluation model for the green retrofitting of existing buildings. Additionally, the evaluation system proposed by this paper and the national standard 'Assessment standard for green building' GB/T 50378-2014 were used in the assessment of a certain office after green retrofitting as a case study. The case study indicates that the evaluation developed by this research are more applicable for green retrofitting of existing building, while the national standard 'Assessment standard for green building' has limitations except for new building. | MENG Chong WANG Qingqin LI Baizhan GUO Chunmei ZHAO Naini | 2019 | Journal of Thermal Science2019，28，6： | 1 |

| 13 | EFFECT OF THE EXISTING STATES OF CHROMIUM ION ON THE COLOR CHARACTERISTICS OF DOPED β-C_2S显示文摘According to the theory of crystal field, theexisting state of chromium ions in β-C2S was studiedwith optical spectra and EPR. The energy levels ofchromium ions were calculated. Chromium ions existin form of Cr4+ and Cr5+ coordinated with distortedoctahedra.
