There are two types of psychological explanation typically offered in theories of deci-sion making under risk. One type attributes risk preference to basic processes common to all people. The theories based on this perspective tend to focus on "cold" psychophysical and cognitive processes. The other type of explanation attributes risk preference to individ-ual differences. The theories based on this perspective tend to focus on "hot" affective and motivational processes. This article tries... There are two types of psychological explanation typically offered in theories of deci-sion making under risk. One type attributes risk preference to basic processes common to all people.

This article tries to elaborate these theories. 风险决策理论对于人们是否作出冒险行为的选择提出了两种比较典型的解释:一种解释把风险决策归因于人们共有的基本过程,即“较冷”的心理和认知过程。这些理论认为风险选择是由人类基本的心理和感觉机制引起的。而另一种解释则把风险决策归因于“较热”的情感和动机过程。这些理论认为,情境和人格因素会增强风险决策的动机并导致风险决策个体差异的存在。本文对这两种解释的不同理论作了较为系统的论述。 The relation between a 2 type attributed grammar and an attributed pushdown automaton is discussed. Moreover, the concept of fuzzy 2 type attributed grammar and fuzzy attributed pushdown automaton are provided, and their relation are studied. So fuzzy 2 type attributed langauge can be recognized automatically. 讨论了2型属性文法与属性下推自动机的关系,进一步给出了Fuzy上下文无关属性文法与Fuzy属性下推自动机,并详细讨论了二者的关系,达到了自动识别Fuzy2型属性文法语言的目的 Liang Junhong Yao Yuzeng Jin Chengzhu, Wang Jianguo Abstracr:The paper includes the determination of homogenization temperature and ice point (salinity), analysis of chemical composition, and draws conclusions: the temperature scope of mineralizatioll is between 100 -320 ℃, the salinity of the ore-forming fluid is medium-low, the fluid type attributes Na(K)Cl -H_2O -CO_2, gold of metallogenetic element migrates as the sulfurhydride complex in. incompetent acid and neutral condition.

Liang Junhong Yao Yuzeng Jin Chengzhu, Wang Jianguo Abstracr:The paper includes the determination of homogenization temperature and ice point (salinity), analysis of chemical composition, and draws conclusions: the temperature scope of mineralizatioll is between 100 -320 ℃, the salinity of the ore-forming fluid is medium-low, the fluid type attributes Na(K)Cl -H_2O -CO_2, gold of metallogenetic element migrates as the sulfurhydride complex in. incompetent acid and neutral condition. Archaeozoic metamorphic rock are regarded as the original rock, atmospheric water becomes the main fluidogent ics, heat and volatile are provided by Hercynian-Yanshan magmatisim. The genetic type of ore district is medium-low temperature and epithermal quartz veins. 以红花沟金矿莲花山矿区51号脉群为主要研究对象,对含金石英脉中的流体包裹 体进行了均一温度、冰点的测定,并对化学成分分析结果进行了计算.最后得出此矿床得成 矿温度范围为: 100~320℃,成矿流体盐度为中低值。成矿流体为Na(K)Cl-H_2O-CO_2 型.成矿元素金是在弱酸-中性的环境中,以氯、硫氢络合物的形式迁移.矿源层为太古代 的变质岩,成矿流体主要来源于大气降水,成矿过程中可能有少量的岩浆水的加入.该矿床 属于中-低温浅成石英脉型金矿床.
