查询词典 clusters

Since the number of trips is a non-negative integer, truncated, and of endogenous stratification, this study empirically analyzes its recreational benefits by the On-site Poisson and truncated negative binomial with endogenous stratification of the Travel Cost Method. Besides, this study adopts TNBES to see how the number of trips disperse and takes the consumer surplus to assess benefits. As to visitors' valuation, this research uses the ordered probit to do empirical analysis and then divides all satisfaction factors by the factor analysis and cluster analysis into four factors and two clusters, which then are taken as explanatory variables.

考量旅游次数为非负整数、截断、内生分层等特质，本研究在游憩效益方面，采旅游成本法中的现场波松(On-site Poisson)、截断式内生分层负二项(Truncated Negtive Binomial with Endogenous Stratification， TNBES)模型做实证分析，并於TNBES模型检定旅游次数之扩散情形，效益之评估采消费者剩余为计算标准；在游客评价方面，采次序波比模型做实证分析，并将游客对科博馆各项因素满意度以因素分析、集群分析，区分为四大因素构面与二大集群，纳入游客评价为解释变数，并探讨消费者剩余对游客评价之影响。

Taking the Late Mesozoic basic-intermediate dike swarms from this area as the main object, we have studied their Petrology, Geochemistry and Isotopic Chronology, and discussed the property of their magmatic source, tectonic setting and origin as well. The significant conclusions acquired are as follows: 1, The Late Mesozoic dike from the coastland of Fujian Province appears as clusters, intruding into the Late Mesozoic granite or volcanic rocks, and the lithologies are diabase, hornblende diabase and quartz-diorite etc, mainly diabase. The mode of their occurrence is mainly precipitous and they tend towards NE, approximately EW or NNE. The dike swarms did not suffer metamorphose or distortion, holding the stress state as the dike formed.

本论文以该地区晚中生代中–基性岩墙群为主要对象，研究了它们的岩石学、地球化学及同位素年代学等，对岩浆源区的性质、构造环境、成因等进行了讨论，获得以下重要认识： 1、福建沿海地区晚中生代中–基性岩墙成群产出，侵入到晚中生代花岗岩及火山岩中，岩性有辉绿岩、角闪辉绿岩和石英闪长岩等，以辉绿岩类为主，产状较陡，北东、近东西及北北东走向，大多未发生变质或变形，保持了岩墙形成时的应力状态。
