With all these developments going on for thousands of years just across the Korea Strait from Japan, it might seem astonishing that in 400 B.C. Japan was still occupied by people who had some trade with Korea but remained preliterate stone-tool-using hunter-gatherers.

尽管先进文明的发展成果数千年不辍地越过朝鲜海峡传向日本，公元前 400 年间的东瀛列岛仍旧被一群滞留在前文字时代、使用石器的猎人－采集者们所占据——而这群人竟还同时维持着与朝鲜间的一定规模的贸易，这多少有些出人意外。

Our study has the following findings: most of the network bandwidth is used by P2P software to transfer the files, approximately 34%. Among the P2P software, the largest service item is the eDonkey, approximately 24%. Most of the traffic in each group is used by only a few users. The behaviors of the broadband users are significantly different than the narrowband users. To download the files is the major purpose of the broadband users, but the narrowband users are used to get their Emails. The files with the video files extensions of dat、mpg、avi and with image file extensions of iso、mdf、img are the primary file types transferred by campus users.

本研究发现：占用频宽最大比例者为P2P软体之档案资料传输，约占总频宽34%，其中最大项目为eDonkey，占总频宽使用量约24%；群组的流量，大部分是群组内少数使用者所使用；宽频及窄频使用者行为有显著不同，其中，宽频使用者是以下载档案为主，而窄频使用者是以收信为主；在档案的传输中，以副档名为dat、mpg、avi等影片档及副档名为iso、mdf、img等光碟映射档为主要传输类别。

As the variation of QRS complex wave is the primary reference criteria on clinical diagnosis of arrhythmia, exact extraction of the features of QRS complex wave is the key problem.

QRS复合波群的形态变化是心律失常临床诊断的重要参考标准，因而准确地提取QRS复合波群的波形特征是心律失常自动化诊断中面临的关键问题。

The molecular phylogenetic trees indicated that Oedipodinae is a monophyletic group and this subfamily is a natural one, but Catantopinae and Acridinae are non-monophyletic. Oedipodnae is a relatively primitive group within the Acrididae, whereas the Oxyinae may have diverged later than Oedipodinae, but earlier than most other species of Acridide.

分子系统树表明：斑翅蝗亚科是一单系群，该亚科是一个合法的亚科，但斑腿蝗亚科和蝗亚科都不是单系群；斑翅蝗亚科在蝗科内是一个相对原始的类群，而稻蝗亚科比斑翅蝗亚科相对进化，比蝗科的其他亚科的种类相对原始。

In Particular, we prove that N is the equality relation on S if and only if S is a semilattice and N is the universal relation on S if and only if 5 is the only principal filter.

其次，证明了N是偏序半群S中的恒等关系当且仅当S是一个半格，N是偏序半群S中的泛关系当且仅当S自身是S中唯一的主滤子。

Make further study of basic principle of ant algorithm, overall analysis and set up mathematic model for it, including transfer probability calculation, time and space complexity, realization problem, advantages and disadvantages and so on.

并从解的质量、时间/空间复杂度、实现难度、算法的优点及不足之处等各项指标对蚁群算法进行全面的分析，并以TSP(Travelling Saler Problem，旅行商问题)为例，介绍了蚁群算法在路径优化问题领域的应用。

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。

The quantum quadratic residue codes are also extended in a nice way, most of which allow, the projective unimodular group, to act.

构造出量子二次剩余码的扩展码，与经典情形类似，对几乎所有的，量子二次剩余码的扩展码都以射影幺模群为自同构子群。

The frequency of genotype AA in prolific group and normal group were lower than low prolificacy group. It can be inferred that gene B made positive effect in prolificacy in Jizhong-goat, and gene A made negative effect in prolificacy.

高产群和普通群体的从基因型频率都比相应的低产群要低，可推测等位基因B对冀中山羊高繁殖性能有正向作用，而A基因对冀中山羊的繁殖性能有负向效应。

A finite group G is called n-decomposable if every proper non-trivial normal subgroup of G is a union of n distinct conjugacy classes of G.

如果有限群G的每个非平凡真正规子群均是G的n个不同共轭类的并，则称G为n-可分解的。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
