The second youngest of six brothers, he began performing professionally with four of them at the age of 5 in a group that their father, Joe, a steelworker, had organized the previous year. In 1968, the group, originally called the Jackson Brothers, was signed by Motown Records. The Jackson 5 was an instant phenomenon. The group's first four singles—"I Want You Back,""ABC,""The Love You Save" and "I'll Be There"—all reached No. 1 on the pop charts in 1970, a feat no group had accomplished before.

杰克逊五岁时开始与自己的四个哥哥一起登台进行专业表演，这个组合是他们做钢铁工人的父亲乔于1962年创建的。1968年，这支原来名叫"杰克逊兄弟"的乐队签约了摩城唱片，"杰克逊五人组"一炮走红，他们首发的四支单曲——《盼你归来》、《ABC》、《你保留的爱》和《我将在那里》在1970年先后登上了流行音乐榜的榜首，此前从来没有任何组合能有如此战绩。

To this end, the CPC Beijing Municipal Committee and Beijing Municipal Government have jointly made "suggestions for promoting the development of banking industry", with Beijing's spatial pattern of financial business structured to consist of a banking street as main central finance district, Beijing CBD as subcentral finance district, Haidian West Zhongguancun District, East Second Ring Road Traffic Business District and Fengtai Lize Business District as promising high-tech and finance districts, and Haidian Daoxianghu, Chaoyang Jinzhan, New Tongzhou City and Xicheng Desheng as financial service background districts.

一主"是指金融街作为金融主中心区，"一副"是北京商务中心区作为金融副中心区，"三新"是新增海淀中关村西区、东二环交通商务区、丰台丽泽商务区作为北京市新兴科技金融功能区，"四后台是四个金融后台服务园区，包括海淀稻香湖、朝阳金盏、通州新城、西城德胜金融后台服务园区。

在评估阶段，第一个自信心水平(50—52％)上的反应时显著短于第二水平(52—59％)、第三个(60—69％)、第四个(70—79％)自信心水平上的反应时。

In this theory, we firstly introduce the basic theory of discrete wavelet transform and lifting scheme. Secondly, we adopt a fully pipelining VLSI architecture for lifting-based DWT. Hence, we can operate on higher working frequency. Besides, we merge a QCB-based DWT method to achieve the higher parallelism for JPEG 2000 encoding system. By changing the output timing of the DWT process, the internal tile memory size can be reduced by a factor of 4. Moreover, the architecture can efficiently perform shape-adaptive DWT and solve boundary extension and subsampling problems. Finally, according to the comparison results with other architectures, the efficiency of proposed architecture is proven.

在这篇论文中，首先我们介绍离散小波转换和提升式架构的基本理论，接下来我们改良提升式架构采用全管线化的硬体架构，因此我们可以操作在较高的工作频率，并且我们合并了以四个编码方块为基础的方式来使得JPEG 2000编码系统具有更高的平行度，藉著改变离散小波转换的输出时序，内部的记体体需求可以减少为原本的四分之一，接著此架构也可以有效地支援可适应形状的离散小波转换，同时解决了边界延伸和子取样的问题，最后根据与其他架构比较的结果，来说明所提出之离散小波转换架构的贡献。

There are four characters that can be found in this process. Firstly, it is a struggle within the political system. In other words, tenants admit the hierarchical rights of ruling class, but reject excess exploit. Secondly, the resistance has various ways, and law is a frequent resort too. Thirdly, collective resistance comes to be the most common form, wealthy peasants always act as organizers and leaders. Fourthly, tenants' resistance processes exhibits obvious different theme of demands in all phrases. Before mid and latter of 14 century, most requirements aim to reject duty beyond custom; while after, mainly to strive for cutting down the rents and tallage.

再次，文章分析了英格兰佃农抗争的四个特点，一是体制内的抗争，即佃农接受统治阶级的等级权利，反抗过度剥削；二是抗争方式多法并举，以法律手段为主；三是集体抗争逐渐成为抗争的主要组织形式，富裕佃农是抗争活动的组织者和领导者；四是抗争历程有着鲜明的时代主题，即以14世纪中后期为界，之前以抵抗领主超出惯例规定的要求为主，之后以争取减免地租捐税为主。

Because the history owes are huge, and the farmer pays the tax and fee in order to get the same quantity public goods, we think that our country rural public goods should adopt the government provision mode a period from now on.

第四，本文的重点在于设计一套用于解决中国农村公共产品政府提供中所存在问题的制度建议，即政府提供模式的规范化，包括逐年实现、各级共担、整体返还和适当调节四个方面。
