The biothermocatalytic transitional zone gas is a new type of natural gas genetic theory, and also an clean, effective and high quality energy with shallow burial depth, wide distribution and few investment. Meanwhile, this puts biothermocatalytic transitional zone gas in important position to the energy resource and it is a challenging front study project. This paper introduces the concept, the present situation of study and developmental trend about biothermocatalytic transitional zone gas in detail. Then by using heat simulating of source rocks and catalysis mechanism analysis in the laboratory and studying structural evolution, sedimentation, diagenesis and the conditions of accumulation formation and so on, this paper also discusses catalytic mechanism and evolutionary model of the biothermocatalytic transitional zone gas formation, and establishes the methods of appraisal parameter and resources prediction about the biothermocatalytic transitional zone gas. At last, it shows that geochemical characteristics and differentiated mark of the biothermocatalytic transitional zone gas, and perfect natural gas genetic theory, and points out the conditions of accumulation formation, distribution characteristics and potential distribution region on the biothermocatalytic transitional zone gas m China. The paper mainly focuses on the formation mechanism and the resources potential about the biothermocatalytic transitional zone gas. Based on filed work, it is attached importance to a combination of macroscopic and microcosmic analysis, and the firsthand data are obtained to build up framework and model of the study by applying geologic theory. Based on sedimentary structure, it is expounded that structural actions have an effect on filling space and developmental cource of sediments and evolution of source rocks. Carried out sedimentary environment, sequence stratigraphy, sedimentary system and diagenesis and so on, it is concluded that diagenesis influences developmental evolution of source rocks, and basic geologic conditions of the biothermocatalytic transitional zone gas. Applying experiment simulating and catalytic simulating as well as chemical analysis, catalytic mechanism of clay minerals is discussed. Combined diagenecic dynamics with isotope fractionation dynamics, it is established that basis and method of resource appraisal about the biothermocatalytic transitional zone gas. All these results effectively assess and predict oil&gas resources about the biothermocatalytic transitional zone gas-bearing typical basin in China. I read more than 170 volumes on the biothermocatalytic transitional zone gas and complete the dissertation' summary with some 2.4 ten thousand words, draw up study contents in some detail and set up feasible experimental method and technologic course. 160 pieces of samples are obtained in oilfield such as Liaohe, Shengli, Dagang and Subei and so on, some 86 natural gas samples and more than 30 crude oil samples. Core profiles about 12 wells were observed and some 300 geologic photos were taken. Six papers were published in the center academic journal at home and abroad. Collected samples were analysised more than 1000 times, at last I complete this dissertation with more than 8 ten thousand words, and with 40 figures and 4 plates. According to these studies, it is concluded the following results and understandings. 1. The study indicates structural evolution and action of sedimentary basin influence and control the formation and accumulation the biothermocatalytic transitional zone gas. Then, the structural action can not only control accommodation space of sediments and the origin, migration and accumulation of hydrocarbon matters, but also can supply the origin of energy for hygrocarbon matters foramtion. 2. Sedimentary environments of the biothermocatalytic transitional zone gas are lake, river and swamp delta- alluvial fan sedimentary systems, having a warm, hot and humid climate. Fluctuation of lake level is from low to high., frequency, and piling rate of sedimentary center is high, which reflect a stable depression and rapidly filling sedimentary course, then resulting in source rocks with organic matter. 3. The paper perfects the natural gas genetic theory which is compound and continuous. It expounds the biothermocatalytic transitional zone gas is a special gas formation stage in continuous evolutionary sequence of organic matter, whose exogenic force is temperture and catalysis of clay minerals, at the same time, having decarbxylation, deamination and so on. 4. The methodology is established which is a combination of SEM, TEM and Engery spectrum analysis to identify microstructure of crystal morphology about clay minerals. Using differential thermal-chromatographic analysis, it can understand that hydrocarbon formation potential of different typies kerogens and catalytic method of all kinds of mineral matrix, and improve the surface acidity technology of clay minerals measured by the pyridine analytic method. 5. The experiments confirm catalysis of clay minerals to organic matter hygrocarbon formation. At low temperature (<300 ℃), there is mainly catalysis of montmorillonite, which can improve 2-3 times about produced gas of organic matters and the pyrolyzed temperature decreased 50 ℃; while at the high temperature, there is mainly catalysis of illite which can improve more than 2 times about produced gas of organic matters. 6. It is established the function relationship between organic matter (reactant) concentration and temperature, pressure, time, water and so on, that is C=f (D, t). Using Rali isotope fractionation effect to get methane isotope fractionation formula. According to the relationship between isotope fractionation of diagenesis and depth, and combined with sedimentary rate of the region, it is estimated that relict gas of the biothermocatalytic transitional zone gas in the representative basin. 7. It is revealed that hydrocarbon formation mechanism of the biothermocatalytic transitional zone gas is mainly from montmorillonite to mixed minerals during diagenesis. In interlayer, a lot of Al~(3+) substitute for Si~(4+), resulting in a imbalance between surface charge and interlayer charge of clay minerals and the occurrence of the Lewis and Bronsted acid sites, which promote to form the carbon cation. The cation can form alkene or small carbon cation. 8. It is addressed the comprehensive identification mark of the biothermo - catalytic transitional zone gas. In the temproal-spatial' distribution, its source rocks is mainly Palaeogene, secondly Cretaceous and Jurassic of Mesozoic, Triassic, having mudy rocks and coal-rich, their organic carbon being 0.2% and 0.4% respectively. The vitrinite reflection factor in source rocks Ro is 0.3-0.65%, a few up to 0.2%. The burial depth is 1000-3000m, being characterized by emerge of itself, reservoir of itself, shallow burial depth. In the transitional zone, from shallow to deep, contents of montmorillonites are progressively reduced while contents of illites increasing. Under SEM, it is observed that montmorillonites change into illite.s, firstly being mixed illite/ montmorillonite with burr-like, then itlite with silk-like. Carbon isotope of methane in the biothermocatatytic transitional zone gas , namely δ~(13)C_1-45‰- -60 ‰. 9. From the evolutionary sequence of time, distribution of the biothermocatalytic transitional zone gas is mainly oil&gas bearing basin in the Mesozoic-Neozoic Era. From the distribution region, it is mainly eastern stuctural active region and three large depressions in Bohaiwang basin. But most of them are located in evolutionary stage of the transitional zone, having the better relationship between produced, reservoir and seal layers, which is favorable about forming the biothermocatalytic transitional zone gas reservoir, and finding large gas (oil) field.

公共政策制定程序对政策可接受性的影响

This research addresses the problems of public policy-making procedures. In conducting our research, we considered public policy as the allocation or reallocation of interests or resources among different members of the public. Due to limited resources, administrations should trade off all interests among different segments of society when formulating a policy. Unfortunately, in recent years there have been several mass conflicts with administration of public policy. This infers that some people’s interests were ignored or harmed by certain policies. According to the theory of procedural justice, people may accept the unexpected result if they consider the procedure is just. This research hypothesizes that there are certain problems in current policy-making procedures and that improving these procedures may make policies more acceptable. A pilot study was conducted by interviewing ten scholars from a range of disciplines. The interview record transcripts were coded by three analysts. The results indicate that: 1) Most of the scholars criticized current public policies as lacking sensitivity to public issues; 2) Most of them considered that current public policies do not resolve problems effectively; and 3) They all considered that psychology research may enhance awareness of public issues and improve the effectiveness of policy. In study 2, the procedure of public policy was tracked and compared with a social survey. The Beijing government would like to increase the taxi fare rate to cope with the rising price of petroleum. Although the majority of delegates in a hearing of witnesses supported the policy consideration, the social survey of 186 residents and 63 taxi drivers indicated that both of them oppose the consideration. The findings indicate that the hearing of witnesses was not able to delegate the opinions of the public, resulting in the policy failing to resolve the problem. Study 3 was a nonequivalent control group quasi-experiment. Visitors of two Internet Website were chosen as subjects for original photo games. For the experiment group, visitors were invited to express their desires and suggestions on the game rules for one week, and then declare rules referencing the suggestions before starting the game. Meanwhile, the control group simply declared the rules at the beginning of the game. Compared with the two games during 23 days, the experiment group submitted more photos than the control group. The results of this research imply that, the good will of policy makers is not enough to make a policy effective. Surveys on public attitudes at the beginning of the policy-making process can allow policy makers to better determine public issues, assess the tradeoff of public interests, help ensure policies are more acceptable, and help foster a harmonious society. The authors of this research suggest that psychology research should take more social level problems into account in the policy-making process.

印象形成中同化和对比效应研究

Impression formation is an important aspect of person perception and has important interpersonal consequences. There are assimilation and contrast effects in impression formation and is still considerable debate regarding the best way to account for them. This present research used trait-implying sentences as priming materials, trait inferences sever as self-generated primes, examined the effect of different trait knowledge in assimilation and contrast effects. Experiment 1 determined the priming and target stimuli of this research by pretest. In experiment 2, participants read trait-implying sentences and resulted in trait inference as self-generated primes, examined the influence of trait activation on impression formation. The results indicated that participants instructed to memorize trait-implying sentences showed assimilation effect, whereas participants instructed to form impression from trait-implying sentences showed contrast effect. Difference to previous studies that emphasized the impact of awareness of the prime in impression formation, this research paid attention to the impact of different trait knowledge that resulted from trait inference. Experiment 3 studied the influence of actor salience on impression formation. The results indicated that when trait-implying sentences that described actors with names and were accompanied with photos of the actors, participants showed contrast under both memorization and impression instructions. Experiment 4 studied the influence of attribution context on assimilation and contrasts. The results showed that contrast ensued when trait-implying sentences were accompanied with the information that suggested a person attribution, whereas assimilation ensued when that information suggested a situation attribution, independent of processing goals. Experiment 5 made a direct test of the effect of different trait knowledge in impression formation. The results discovered that when abstract trait concepts were activated they act as a general interpretation frame in encoding stage, whereas when specific actor-trait links were activated, the activated information is likely to be used as a comparative standard in judgment stage. All studied indicated that there are two types of activated trait knowledge in trait inference: abstract trait concepts versus specific actor-trait links. When trait inference activated abstract trait concepts, the activated information serves as interpretation frame and lead to assimilation effect during impression formation, when trait inference activated specific actor-trait links, the activated information is more likely to be used as a comparative standards and resulted in contrast effects. These findings have important implications for understanding the mechanism of impression formation and practical values for interpersonal communication.
