Trichomoniasis is a sexually transmitted infection that affects both men and women and results in roughly 7.4 million new cases in the United States each year, according to the U.S.

毛滴虫病是一种可在男性和女性间传播的性传染疾病，根据美国疾控中心的数据，美国每年有大约七百四十万新发病患者。

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。

Every publication in America today includes pages that would appear, to the purist of forty years ago, unbuttoned gibberish .

The Samara Sutradhara is a scientific treatise dealing with every possible angle of air travel in a Vimana. There are 230 stanzas dealing with the construction, take-off, cruising for thousand of miles, normal and forced landings, and even possible collisions with birds. In 1875, the Vaimanika Sastra, a fourth century B.C. text written by Bharadvajy the Wise, using even older texts as his source, was rediscovered in a temple in India.

Samara Sutradhara是一篇涉及用维曼拿空中旅行的每一种可能，有230节是有关构造，起飞，巡航一千里，普通和紧急降落，甚至可能碰到鸟类。1875年，一本由智者巴拉瓦杰在公元前四世纪写的《维曼尼卡萨塔》，甚至在他的内容里面引用更古老的资料，在印度一座庙宇里重新被发现。

The results showed that:1 78 volatile constituents were identified in the oil,which were mainly caryophyllene,1,5,9,9-tetramethyl-1,4,7-cycloundecatriene,germacrone,eudesmol and furfural,etc.2 The aroma quality and intensity of cigarette were improved,irritation was reduced,and a...

结果表明：①满山红挥发油中共鉴定出78种挥发性成分，主要有石竹烯、1，5，9，9四甲基-1，4，7环十一碳三烯、杜鹃酮、桉叶醇和糠醛等；②该挥发油具有提高B2F和C3F等香气质和香气量，降低刺激性和改善余味的作用。

In that, the density of NMDA rece ptor of rats born to dam rats received morphine treatment were significantly l ess than the control rats on postnatal day 14 (PND 14). It suggested that rat s born to chronic morphine addicted dam rats could induce the neuronal NMDA re ceptor downregulation.

在过去本实验室已经证实，长期投与吗啡的母鼠所生的幼鼠脑中，N-me thyl-D-aspartate receptor (NMDA receptor，一种兴奋性胺基酸的接受体之一)的密度在出生后第十四天比起控制组有明显的下降。
