In the last two sections of this chapter,we give two applications of the new Z_p geometrical index theory to the existence of periodic solutions and subharmonic solutions for a class of wave equations with deviating arguments.

在本章中，我们还给出广义Z_p几何指标理论在含有偏差变元的波动方程中的应用，得到周期解与次调和解存在(来源：12e2ABe9C论文网www.abclunwen.com)性的两个结果，即使对正常变元的波动方程，这些结果也是新的。

In fact, it was proved by Pastijn that the idempotent semirings for whichis a congruence form a proper subvariety of the variety of all id empotent semirings. Also the defining equations were given with three free var iables of this variety.

Pastijin证明了：是S上的同余的幂等元半环S的全体构成了幂等元半环簇的一个子簇，进一步还给出了这个子簇的含有3个变量的簇等式组，当时不知道这个子簇是否有两个变量的簇等式组。

The results show that defect states appearing both in the valence and conduction band induce the corresponding electrons scattering because of the deformation of Stone-Wales defects (two pentagon-heptagon pair topological defects).

结果表明，由两个五元环—七元环(5-7)拓扑缺陷对构成的Stone—Wales形变使价带和导带中出现缺陷态，导致相应能级的电子散射。

Based on estimates, 3.82 billion yuan profit in two trading days, or over 150 million yuan.

The economic efficiency estimate was carried on to this production model and the results indicated that " triticale + silage com" two crops one year can make net profit of 12765 Yuan/hm^2 /year.

对该生产模式进行经济效益估算，结果表明，"小黑麦＋青贮玉米"一年两作年纯利润为12765元／hm^2，比一年一作玉米生产增收1500元／hm^2，是山西北部农区值得推广的生产模式。

Multiple antenna arrays are often used to overcome the effect of channel fading which is caused by multipath interference. In chapters 4 and 5 ,we derive spatial correlation equations of ULA ,UCA and CRA for two types of angular spread distributions (uniform distribution and truncated Gaussian distribution).We also compare the difference between these antenna arrays by showing the bit error rate simulation results and discuss the relationship between BER and spatial correlation. In a multi-user mobile radio environment , we present simulation results to show that adaptive MBER algorithms have better performance than the traditional MMSE algorithm.

多天线阵列常被用来克服多重路径干扰导致通道衰减的影响，我们对各种天线阵列架构进行比较，在第四、五章中推导出ULA、UCA与CRA个别对两种角度扩散机率密度分布的空间相关性函数，由实际实验模拟的位元错误率图形比较天线阵列间的差异，并讨论位元错误率与空间相关性之关连，在多用户端行动通讯环境下，我们也由模拟验证可适性MBER演算法，会比传统MMSE准则有更好的效果。

During the investigation of the reactivity of O_SCl_2(PPh_3)_2CH=C(PPh_3CHCH=CH_2 and O_SCl_2(PPh_3)_2CH=C(PPh_3C(=CH_2)CH=CH2, several stable osmacycles with novel structure, such as osmabenzenes, osmafurans, osmacycles containing intramolecular-coordinated allene, intramolecular-coordination osmacycles containing osmacarbene, an osmacyclopentadiene, were isolated during the investigation of the reactivity of O_SCl_2(PPh_3)_2CH=C(PPh_3CHCH=CH_2 and O_SCl_2(PPh_3)_2-CH=C(PPh_3C(=CH_2)CH=CH_2.In addition, some convenient and efficient methods to prepare these osmacycles were developed.

首先，合成出两种具有反应活性的金属杂五元环IC配合物OsCl_2(PPh_3)_2CH=C(PPh_3CHCH=CH_2和OsCl_2(PPh_3)_2CH=C(PPh_3C(=CH_2)-CH=CH_2，并对它们进行了系统表征；进而，研究了这些活性五元配合物的反应性，合成出多种稳定的锇杂环配合物，其中包括锇苯、锇呋喃、含配位联烯的锇杂IC环化合化物、含锇卡宾的IC环化物、首例锇杂环戊二烯化合物等多元化的产物。

The A Xiang after abdication is faineant, an accidental opportunity vended empty glove through the classmate's relation, managed a bit fund, begin to immerse oneself in the Internet item that makes him then, his discovery is aimed at market of Yang Ling this locality, especially recreation lives kind, the website that is aimed at undergraduate of Yang Ling place especially is returned, then, he prepared to construct Yang Ling city connects a network, a collect hits communication of the member that fold news peace conference to live at the recreation of an organic whole kind of website, he still made a city know member card, oneself a person begins to begin to sell in ave lane of Yang Ling, with the businessman the negotiation cooperates, although initial stage is very much,the person does not approbate this his website, but, a Xiang relies on him hold to and try hard, technology of collect of a person, beauty is made up, sale, business affairs cooperates at a suit, the operation that makes Yang Ling city connects a network eventually was on the right path, yang Ling city connects a network the member of this website also expands with each passing day, become build Yang Ling between local businessman and consumer a ligament, a Xiang also carries businessman ad eventually, the member collects fees the road that waited for mode to be on gain, from a first month hundreds of yuan, go to thousands of yuan again, the scale that reachs ten yuan one year of present again, be less than time of two years, in the small town that A Xiang is not worth 100 thousand population this in Yang Ling, enter a when went out to belong to oneself poineering grade.

辞职之后的阿祥无所事事，偶然的一个机会通过同学的关系倒腾了一次空手套，弄出了一点资金，于是开始埋头做他的互联网项目，他发现针对杨凌本地市场，尤其是娱乐生活类的，特别是针对杨凌当地大学生的网站还没有，于是，他筹建了杨凌城市通网，一个集打折信息和会员交流于一体的娱乐生活类网站，他还制作了城市通会员卡，自己一个人开始在杨凌的大街小巷开始销售，与商家谈判合作，尽管初期很多人并不认可他的这个网站，但是，阿祥依靠自己的坚持和努力，一个人集技术、美编、销售、商务合作于一身，终于使杨凌城市通网的运营走上了正轨，杨凌城市通网这个网站的会员也日渐壮大，成为搭建杨凌当地商家和消费者之间一根纽带，阿祥也终于通过商家广告，会员收费等模式走上了盈利之路，从最初的一个月几百元，再到几千元，再到现在的一年十几万元的规模，不到两年的时间，阿祥在杨凌这个不足十万人口的小城里，闯出了属于自己的一条创业之路。
