Base on the data from the secondary industry of 30 sample cities, this dissertation adopts the method of empirical analysis — Primarily the statistical technique named "Prime Component Analysis", to answer the basic question "what are the prime factors in determining the secondary industrial grads of the sample cities?"

鉴于此，本论文运用实证分析的方法，以长江三角洲和珠江三角洲30个城市的第二产业为例，将研究重心放在对产业梯度影响因素的分析之上，进而粗略地总结了这两个区域从1978年到1990年，再到2002年这二十多年之中，第二产业梯度转移的大致规律。

The combined classifiers are obtained by training the sample set. Using the sample to centralize the ratio of different kinds of targets can reflect prior probability of various classifiers.

用于组合的各个分类器通常是基于样本集通过一定的训练得到，样本集中不同类目标的比率可以反映分类目标的先验概率。

In Sample TVG-1, aragonite is replaced by calcite and the pseudomorph of the former is observed, suggesting that this sample was formed earlier than the other because phase transformation of aragonite to calcite has occurred.

TVG-11中存在大量的文石，而TVG-1只保留了已转化为方解石的文石假象，据此可以推断TVG-1的形成要早于TVG-11。

Based on different thickness hydroxylation content in quartz sample, the changes of Hydroxyl peak 3675cm^(-1 intensity is obvious of different thickness in quartz sample, and withe increase of Quartz plate thickness, the hydroxyl peak transmittance increases.

通过对石英样品中不同厚度羟基含量分析得出，对于不同厚度的石英样品，羟基峰（3675cm^(-1)左右）的强度变化十分明显，石英片厚度的增加，羟基峰的透射率增大。

In this study, we use a sample of 186 firms in Taiwan that have export ratio for at least 10 percent in the sample period to examine their exchange rate exposures and the effect of usage of currency derivatives on currency exposures. In the determinants of exchange rate exposure, we find that exchange rate exposure is positively related to the foreign sales ratio, firm size and quick ratio.

过去相关外汇暴露的文献，主要在讨论国际企业的外汇暴露的大小与其决定因子，受限於企业使用衍生性金融商品交易资料取得不易，过去的模型中通常仅以虚拟变数的方式，来分析公司使用衍生性金融商品避险的影响，而未进一步分析其使用程度对外汇暴露的影响。

With the sample of the newest financial data of the company issued by the ST in 2006-2007, and the sample of the normal company at the same time, the study takes example for the financial data released by the listed companies and selects the ROE（Rate of Return on Common Stockholders'Equity ）, the sales net profit rate and the current ratio of three financial targets, which are discriminated and analysed with univariate method.

摘 要：本文以我国上市公司为研究对象，通过对上市公司财务危机的定义、财务危机与企业失败的关系、以及财务危机预警的研究，以2006-2007年上市公司最新一次被ST发布的财务数据为估计样本，以同期的正常公司为配对样本，选取净资产收益率、销售净利率和流动比率三个财务指标，运用单变量方法进行判别分析。
