习惯法与国家法的冲突和互动

习惯法是中国固有法资源的重要组成部分,在中国乡土社会有着深厚的文化根基,发挥着独特的价值功能。在中国法治建设中,习惯法与国家法有其冲突的一面,也有其一致性,应寻求习惯法与国家法的相互妥协与合作。     

Measurement structures and psychological laws

Empirical laws psychology may be based on physical measurements (for example, voltages, times), counting, ordering, or just classifying. It is a pointless, though widespread practice to use a physical measure or a count as a "definition" of a psychological variable; this practice obscures the fact that all one has done is measured a physical variable, or counted. What is important are the empirical laws that are established by use of such quantitative or qualitative observations. Some kinds of empirical relations and laws yield measurement structures, akin to the qualitative structures underlying fundamental measurement in physics. Measurement structures are empirical structures that can be described most simply by introduction of a new numerical function; such a function is a new measure, and is typically interpreted as measuring some particular psychological variable Measurement structures, formulated abstractly, sometimes provide valuable tools for formulating new empirical hypotheses to be tested; but in many instances, other kinds of theory may be more appropriate. The main focus of research ought always to be the discovery of simple laws; these may or may not lead to new measures.     

催化裂化汽油质量衰变规律

采用43℃催速储存实验方法,以未洗胶质、实际胶质、酸度、色度、诱导期为表征指标,研究了催化裂化汽油的安定性变化规律,并利用最小二乘法、相关分析、方差分析等方法考察了催化裂化汽油安定性的影响因素,建立了安定性指标与储存时间的关系模型以及安定性指标间的定量关系。结果表明：催化裂化汽油在储存过程中,由于不饱和烃的氧化反应导致质量衰变,安定性指标均随储存时间的延长而变差;生产原料不同导致催化裂化汽油的质量衰变速率不同,且对安定性的影响大于储存时间的影响;未洗胶质、酸度与实际胶质的相关性良好,相关系数均在0.9以上,且环状烯烃、双烯烃等化学组成对衰变速率的影响显著。
