ABSTRACT Particle filter is a new real time inference algorithm which is based on Bayesian inference and Monte carlo method. Because of its unique characteristics such as flexible, easy to implement, parallelizable, extensive applicability and efficient to process nonlinear problems, particle filter has been paid more and more attention in recent years and becomes a new and very promising hot topic in applied statistics, signal processing, automatic control, artificial intelligence and machine learning communities. At the same time, the formidable increasing computational power and some recent developments in applied statistics and probability theory has stimulated many advances in this field.

始于20世纪90年代初的粒子滤波器技术是一种基于贝叶斯推理和蒙特卡罗方法的实时在线推理算法，因其具有灵活、易于实现、并行化、应用前景广阔以及有效处理非线性问题等特点，受到了越来越广泛的重视，成为统计学、信号处理、自动控制、人工智能、机器学习等领域新的研究热点，同时伴随着计算机计算能力的超指数增长以及应用统计学、概率论等一些学科的不断进步，使该领域的研究得到了迅速发展。

Aim-teaching, which originates from the 80s to 90s in the beginning of the last century, is a kind of teaching mode that developed by Chinese pedagog on the basis of American educator Tyler's "Principles of Make Curriculum" and his student-Broome's "Educational Target Taxology".

Rudolph Penner, a former CBO director, predicts that the federal debt (excluding debt owed to other parts of the federal government) will soar from 38% of GDP this year to 55% at the end of 2010, the highest since the early 1950s, when the country was still in hock from fighting a war.

前国会预算办公室主任鲁道夫·彭纳预计联邦债务（还不包括欠联邦政府其它部门的债务）到2010年将由今年占GDP38%的份额飙升至55%，达到20世纪50年代初以来的最高水平，当时美国由于一场战争仍处于负债状态。

Liu Department is the "double Pikeman", combat effectiveness is very low, the strong fortifications in the absence of the field based on, basically all of the opponents is not the Central Red Army.

After the statistics, to the beginning of 1990s, the planetoid which registers had more than 4000, although but also some multitudinous planetoids (had more than 50 ten thousand according to record) already to discover, waited for actually further confirmed.

In 1980s, a group of Indian excellent historians started to do a research on theplebeians in South Asian society and explored every aspect of plebeian\'s situation.

Then,in the early 1940s, John Mauchly and J.Presper Eckert,Jr.,of the University of Pennsylavania designed and built a vacuum tube computer,which they called the electronic numerical inegrator and calculator;it was completed in 1945 and installedat Aberdeen Proving Ground,Maryland. ENIAC used 18000 electron tubes,which required tremendous amounts of power;its failure rate wa high and it was difficult to program because a plugboard was required.

那么，在20世纪40年代初，约翰mauchlyj.presperEckert先生和霍尔特，该大学设计建造了pennsylavania真空管计算机，它们被称为电子计算器、数值inegrator；这是1945年建成并installedat马里兰州的阿伯丁。eniac使用18000电子管，这需要庞大的权力；它的失败率偏高，难以以佤节目因为插件需要。

In the kaleidoscope of classical painting styles, such as the everyday life of Holland classical genre painting, the nobly preciseness of French neoclassicism, the fantastic magic of Spanish classicism and the priggism of "the Pre-Raphaelite Brotherhood" in British, each has its own thread of story and development of style that is clear and distinct.
