英语翻译1.Reach and frequency.Advertisers must choose some combi
英语翻译
1.Reach and frequency.
Advertisers must choose some combination of reach and frequency to attain their
advertising objectives.Reach is defined as the number of individuals or households exposed to at least one ad during a given period of time—typically four weeks.The term can be used in connection with a single media vehicle or a media schedule comprising a number of different media vehicles.Reach is typically expressed as a percent of the target audience:for example,if the target audience was 100.000 persons and the media schedule reached 70.000,the reach would be 70 percent.Ordinarily,costs rise at an increasing rate as higher levels of reach are sought.
Duplication occurs whenever a marketer purchases a second medium .some portion of the audience of the first medium is almost always part of the audience of the second medium.Assume that medium A has an audience of 100.000persons and medium B,90.000,if 40.000 of the persons exposed to medium B are also members of A’ s audience,then buying the two media yields an unduplicated audience of 150.000---not 190.000,duplication leads to frequency,which is the number of times the target audience is exposed to a message within a given tome period--- usually four weeks.
There are several problems in using these measures.First is the matter of defining the target audience and correlating it with the audiences reached by the various media vehicles.A second problem is defining exposure---is it an opportunity to be exposed to a given message or is it an actual reading of a print ad,actual watching of a TV commercial,or actual listening to an ad in radio?Needless to say,it is a difficult task to measure exposure no matter how it is defined.Third,not all who are exposed are of equal value to the advertiser----some may not even be prospects.Fourth,how should successive exposures be weighted?Is a second exposure worth more than a third?And how much time should elapse between exposures?
Reach and frequency measures ate used to prepare the advertising schedule,which,in turn,determines total advertising expenditures.In estimating the cost of a given schedule,media planners simplify their task by using gross rating points,which ate calculated by multiplying reach by average frequency.Assume a reach of 70 percent and a desired average frequency of four,the number of GRPs would then he 280.By multiplying this by an estimated cost per GRP,the cost for a proposed media schedule can he estimated.

英语翻译Radio Frequency Identification(全译“无线射频识别”,英文简称RFID).无线射频
英语翻译
radio frequency identification(全译“无线射频识别”,英文简称rfid).无线射频识别技术是20世纪90年代开始兴起的一种自动识别技术,rfid技术利用无线射频方式在阅读器和射频卡之间进行非接触双向数据传输,以达到目标识别和数据交换的目的.与传统的条型码、磁卡及ic卡相比,射频卡具有非接触、阅读速度快、无磨损、不受环境影响、寿命长、便于使用的特点和具有防冲突功能,能同时处理多张卡片.
rfid技术是21世纪发展最快的一项高科技技术,随着与传统网络的结合,rfid技术展现出巨大的市场应用潜力,被称为“物联网”和“第二代internet".目前,rfid已成为it业界的研究热点,被视为it业的下一个“金矿”.各大软硬件厂商,包括ibm,motorola philips micorosoftoracle等在内的各家企业都对rfid技术其及应用表现出了浓厚的兴趣,相继投***量研发经费,推出了各自的软件或硬件产品及系统应用解决方案.
随着科学技术的进步,作为数据采集方式的自动识别技术得到迅猛的发展,其中应用在物流与供应链领域的rfid技术越来越受到关注.发达国家已经把这项技术应用到图书馆的流通管理、典藏管理、安全管理等方面.目前美国的大型物流公司、零售商店、医药公司都在陆续试用这种短距离无线通信技术主要用于对货物或商品的质量、数量的控制以及对库存更精确、安全、有效的管理.***的rfid应用主要集中在中低频领域(工作频率小于30mhz ) ,如身份识别、安全门禁、电子购票、交通等领域.如果能把该功能集成到手机上使其成为人们购物结算的工具那么移动运营商就有希望从行业合作中获得新的收益.未来的世界,rfid将无所不在.
如美国的大学图书馆就有300多家应用了rfid技术,新加坡拥有第一个全面应用rfid技术的智能图书馆等.***也正在引进这项技术,在2006年深圳图书馆已部分应用此项技术.这项技术给图书馆界带来了巨大的变化,有着非常广阔的前景.

英语翻译
AM-Frequency Sweep Test
The Bohlin’s Dynamic Shear Rheometer (DSR) was used to determine the complex
shear modulus (G*) of AM at high and intermediate temperatures.The frequency
sweep test was conducted at frequency levels of 1 Hz through 60 Hz at log-increments
at temperatures of 15,20,25,34,46,58 and 64oC.The test was conducted under the
controlled stress mode.The applied shear stress at each temperature was selected such
that it was within the linear visco-elastic range.The specimen was conditioned by
applying 100 cycles at 10 Hz at one-half the stress level that was used in the test.
AM-Fatigue Test
The test was conducted under stress controlled mode,and a single frequency of
loading of 1.58 Hz was applied at 25oC.Shear stress level of 14,000 Pa was applied on
the AM.The test was terminated at load repetitions of 10,000 cycles.The preconditioning
of the AM was done by applying 200 cycles of loading at a frequency of
10 Hz before conducting the actual fatigue test.The G* was plotted as a function of the
number of load repetitions to identify the fatigue failure in the mixture.

从数学概念上说,频率既可以是离散的也可以是连续的.
自然界的频率,都是连续的(频谱,光谱等等).但是在计算机当中通常需要处理的是采样以后的信号,此时通过采样频率得到的是离散的信号.
你说的频率是不同的概念,人数,次数等等是在统计学中的频率--这个是离散的变量.
如果采样频率无限大(比方说在单位的样本里面抽取的数量足够多),离散采样的结果就基本上可以反映样本客观的形态了.

把式中的T、T0替换为1/f、1/f0,就可以得到f=f0(1-2v/c)

每1000年里,通过结肠镜检查得知患上终生结直肠癌病例的频率在7.7 到的12.6,这是在精确完善的仪器得到的结果.当仪器还是是不完善的的时候,得到的频率是分别从7.7到20.9.当没有进一步的执行严格筛选的时候,就会有31.3的终生结直肠癌病例.

haven't had any archives that's been to this frequency
听写voa时遇到这么一句话:Until now we haven't had any archives that's been to this frequency.
翻译是:截至目前,我们没有任何存档频率如此职高的档案馆.我不能理解那个修饰archives的定语从句“that's been to this frequency”的语法结构,求大神相助.

that's been to this frequency的完整形式是,
that has been to this frequency.相当于:
An archive has been to this frequency.
这里的has been to 是已经达到……的意思.

comb
Two laser combs with different repetition frequency are used here for determination of the corresponded comb number n and n+m.
在这句里是啥意思啊,实在搞不懂!

译文:
此处用两个重复频率不同的合成激光来确定相应的合成数量n和n+m.
此处的comb是combination的缩写/简称.
comb number是指“合成的数量”

英语翻译
The frequency value,however should stay relatively the same for the clean sensor,and the software uses the stored clean frequency to determine when the sensor is sufficiently clean.

这段话要意译才更易懂:
对正常的传感器来说,该频率值是相对稳定的.软件通过将其与内部存储的正常频率值比对,来判断传感器是否正常.

英语翻译
The objective of this tutorial is to study the frequency distribution of different air pollutants.Compute and plot the frequency distribution of RSP,SO2,NO2 for:
(i) Hourly average data (for the year 2012)
(ii) Daily average data (for the year 2012)
(iii) Monthly averaged data (for the year 2001 to 2012)
(iv) Yearly average data (for the year 2001 to 2012),(only 13 data points)
Repeat part (iv) again using running average (prepare a column of daily average from 2
Jan 2011 to 31 Dec 2012,then average from n = 1 to 365 days and assign this average
as the yearly average at 1 Jan 2012; repeat for n = 2 to 366 days and so on,then you will get about 365 yearly averages).
不明白第(iv)部分要我干什么,就翻译这部分就行了.

不用感谢我我帮你把所有的翻译出来:
本教程的目的是研究不同的空气污染物的频率分布.计算和绘图的悬浮粒子,SO2的频率分布,NO2:
(我)平均每小时的数据(为2012年)
(二)每日平均数据(为2012年)
(三)月平均数据(今年2001到2012)
(四)年平均数据(今年2001至2012),(13个数据点)
重复第(四)再次使用的滑动平均(2制备柱日平均
月2011日至2012月31,那么平均从n = 1到365天,平均分配这
由于每年平均1月2012;重复n = 2至366天等等,那么你将获得约365的年平均值).

当vfb低于0.4v时,转接频率将会降至50khz来降低周期下限.
