For the sake of solving the problem of great rotary inertia and forged steel rockerarms bad wear-resisting property in the engine of Xia Li cars with modelTJ370Q TJ376Q, we utilize the assembly theory of creative engineeringmethodology to respectively make the aluminum alloy materials and siliconnitride engineering ceramics as base stock of rocker arm and cabochon glut. Inthis way, the goodness of these two kinds of materials are fully strengthened. Forthe new rocker arms, their comprehensive property are enhanced and the cost ofmanufacture is lower than before.

为了解决夏利轿车发动机TJ370Q和TJ376Q中所装配的锻钢镀硬铬气门摇臂所存在的转动惯量大、圆弧面耐磨性差的问题，项目研制中运用创造性方法学中的"组合"原理，有针对性地选用铝合金和氮化硅陶瓷这两种具有不同性能特点的材料分别作为摇臂基体和工作圆弧面镶块，充分发挥两种材料各自不同的性能优势，从而达到提高产品综合性能，降低制造成本的目的。

Exterior Opposite Angle Area: According to one angle area of the triangle, if we extend the two angle lines to the opposite direction, the area formed by the extending lines which like mirror area to the original angle is called here Exterior Opposite Angle Area.

外部对角映射区：针对三角形的一个角，将构成该角的两条相邻线段进行对角方外部对角映射区向的虚线，这两条虚线围成的区域就是该三角形一个角的外部对角映射区。

数值计算结果表明，光场的两个正交分量的均方涨落均呈现周期性的压缩，其压缩程度与系统的初始状态有关；光场光子的统计性质也依赖于系统的初始状态，光场两模之间的相关是一种非经典相关。

The Yankees, however, had taken advantage of three Seattle errors and staked Wang to a 3-0 lead after two. Seattle's Erik Bedard was unhittable after that, and retired the final 14 batters he faced, but with Wang on the mound — and Kyle Farnsworth, Chamberlain and Mariano Rivera after him — the Yankees didn't need the two insurance runs they got in the eighth.

反观洋基，在前两局就趁著水手的三次失误打下3-0给小民当本钱，此后水手的Erik Bedard就不再挨打，接连解决14名打者，但是这可是王小民在投球，后头的方师傅，张伯伦，李维拉也不赖，洋基根本不需要八局多打下的两分保险分。

First, this paper gives an introduction of some methods of unequal probability sampling, their estimators and variance estimators, including sampling with pps with replacement, methods of sampling without replacement suggested by Brewer, Durbin, Sampford , Des Raj , Murthy , Rao-Hartley-Cochran. Then, at the basis of Rao and Bayless's study , we consider that population can be splited two random subpopulations, which are respectively drawn from different infinite super-populations, and compare the stabilities of estimators of the methods that given above.

本文首先从理论上介绍了若干种不等概率抽样方法，它们的估计量、估计量的方差及其估计，其中包括有放回PPZ及PPS抽样，不放回不等概率抽样中的Brewer、Durbin、Sampford、Des Raj，Murthy、Rao-Hartley-Cochran等人的方法；其次，在Rao和Bayless两人就样本单元数n=2的情形对上述抽样方法进行比较的基础上，将总体随机地分成两个子总体，视每个子总体取自不同的线性超总体，在文中，我们利用计算机实现随机分组，并通过画图比较各方法估计量的稳定性，结果表明，对变异系数C.V。

Two array fashions, hexagonal and square arrays of the colloids were observed by SEM images.

同时在所制备的胶体晶体中观察到了四方排列和六方排列两种排列方式，分析了这两种排列的转化主要是受温度和胶体晶体中缺陷的影响。

To demodulate the OFDM signals accurately, channel estimation algorithms are adopted. This paper examines the slow-fading estimation algorithms based on block pilot arrangement: LS and LMMSE algorithms, as well as the fast-fading channel estimation algorithms based on comb-type pilot arrangement: linear and transform domain interpolation algorithms.

本文分析了导频分布的两种方案：1块状导频分布，对基于块状导频分布方案的慢衰落信道估计算法：最小平方和线性最小均方误差算法进行了计算机仿真，比较了二者的估计性能，以及各自的优缺点；2梳状导频分布，对基于这种分布方案的快衰落信道估计算法进行了研究，对两类经典算法：线性插值法和基于变换域的插值法分别进行了理论分析和计算机仿真。

Leifeng Pagoda was first built in Northern Song Dynasty 977 AD, two years of peace and rejuvenating the country, originally for the King of Wu and Yue Feng Qian-shu Tibetan Buddhism as a relic to pray for peace and prosperity Luo Ji-fat built, the original name of Princess tower, tower of brick-wood structure leifeng well-known high tower, and Chinese folk legend of White Snake widespread myth is closely related to the story in the embodiment of white snake Bai Suzhen have been a result of the pursuit of true feelings and sea monk imprisoned in Leifeng Pagoda, the Leifeng Pagoda and therefore the statement of history far and wide Leifeng Pagoda on the fire hit twice, the first declared in the Northern Song Dynasty and years, because of Fang La uprising, a torch outside the wooden structure burned to the tower to the Southern Song Dynasty years, have been rebuilt Leifeng Pagoda, West Lake, one of Dusk is the leifeng circulated Leifeng Pagoda at that time subjected to fire the second Jiajing in the Ming Dynasty, when the pirates violation of Hangzhou, Leifeng Pagoda burnt again, remaining tower stands on the shore of West Lake, this case continued until the end of the Qing, Leifeng Pagoda finally collapsed due to overwhelming cause of the collapse on the Leifeng Pagoda in history is also very controversial, in general there are two versions of the previous two years in the clean-up sites Leifeng Pagoda time, found that a considerable portion of the tower of brick side of a small hole in the cave there are Buddhist in the past, people have incorrectly relay erroneous messages will pass into a gold brick by brick, the tower blocks have take-home, resulting in the collapse of the tower argument argument, one of the two, due south is the land of plenty since ancient times, but Hangzhou is the House of silk and tea, the history of Hangzhou on the rich silk, and every year when the silkworms cocoon silk, a variety of reasons, tend to have a large number of cocoon death, Over the past superstition, misconception that cocoon cursed, while the Leifeng Pagoda is a town of white snake demon, thinking that would be the Pagoda bricks at home, they can withstand the erosion of Yao Xie, you have to take a sericulture, his family wealth take a course of time, in particular, Taki shaft damage due to the common people, coupled with those in power are indifferent Leifeng Pagoda finally at 13:40 on September 25, 1924 came crashing down

雷峰塔初建于北宋太平兴国二年公元977年，原本为吴越国王钱淑为奉藏佛螺髻发舍利子以祈祷国泰民安所建，原名叫皇妃塔，塔为砖木结构雷峰塔的知名度之高，与中国民间广泛流传的神话传说白蛇传密切相关，故事中白蛇的化身白素贞因追求人间真情而被法海和尚囚禁于雷峰塔下，雷峰塔因而声明远播历史上的雷峰塔曾两次遭遇大火，第一次是在北宋宣和年间，因方腊起义，一把火把外面的木结构塔身加以焚毁到了南宋年间，曾重修雷峰塔，西湖十景之一的雷峰夕照就是在那个时候流传的雷峰塔第二次遭受火烧是在明朝的嘉靖年间，当时倭寇侵犯杭州，雷峰塔再次把火焚，仅剩塔身屹立于西湖之滨这种情形一直持续到清末民初，雷峰塔终因不堪重负而倒塌了关于雷峰塔倒塌的原因，历史上也很有争论，一般来讲有两种说法，前两年在清理雷峰塔遗址的时候，发现有相当一部分的塔砖一侧有一个小洞，在洞里有佛经而在过去，老百姓们以讹传讹将经砖传成金砖，纷纷将塔砖拿回家，从而导致塔的倒塌此说法之一说法之二，由于江南自古就是鱼米之乡，而杭州又是丝茶之府，历史上的杭州就盛产丝绸，而每年蚕宝宝吐丝结茧之时由于多种原因，往往有大量的蚕茧死亡，过去的人迷信，误以为蚕茧中了邪，而雷峰塔是镇妖的白蛇，以为将雷峰塔的砖放在家里，就可以抵挡妖邪的侵蚀，你家养蚕拿一块，他家求财拿一块，久而久之，塔身特别是塔基由于老百姓的破坏，加上当权者的漠不关心，雷峰塔终于在1924年9月25日下午1点40分轰然倒塌
