For the sky tour, one can take a solar energy light aircraft and, in the manner of a bird, soar freely about. For the water tour, one can take the tour boat. All boats are run on a fixed schedule and travel pre-determined routes . One can either go up the Ming River in a boat, to see the world famed cliff frescos of Balai Mountain , or take the divers' shuttle and enjoy the delight of being a fish. As for land tour, one can go donkey or horseback riding over hill and dale. However, I recommend Mr. Wen skip the last one.

Ladies and gentlemen,today i want to talk about the differences between english and chinese.english is very different form chinese.the sounds are different .the grammar is different.and the writing is totally diffenent.it is very difficult to speak english well.if you want to speak english well.you must forget about the differences.just practise corract sentences until you are used to them .the more sentences you can blout out.the better you can express yourself.if you believe in yourself and practise crazily every day .you'll make it .you'll conquer english .chinese is the most difficult language in the world .if you can speak chinese,you can speak english.
女士们,先生们。今天我要谈谈英语和汉语之间的区别。英语是非常不同于汉语的。例如发音不同,语法不同,还有就是书写完全不同。想说好英语是件非常困难的事情。如果你想说一口漂亮的英语,你就必须忘记那些不同之处。尽量多操练正确的句子直到你熟悉他们。你能脱口而出越多的句子,你就越能如意的表达自己。如果你相信自己并且每天都疯狂的练习,那么你就会成功。你就会攻克英语。汉语是当今世界最难的语言,如果你可以说汉语,那么你就可以说英语。

These antennas can cover GSM900/DCS/PCS/UMTS operation. In the chapter 2, the antenna is designed based on the concept of monopole antenna. Furthermore, the antenna structure have two radiant paths and coupled each other at tail end to do impedance matching. In addition, to raise distance between radiation plane and ground will avoid capacitative effect effectually. In the chapter 3, the antenna is designed based on the concept of planar inverted-F antenna. Furthermore, that the antenna structure have two radiant paths and coupled each other at tail end to do impedance matching is similar to chapter 2. But there is a difference in them. We can choose the short position to change input impedance at this structure. In the chapter 4, the antenna is designed based on the concept of planar inverted-F antenna which takes coupled-fed. It will produce the first mode and high-order mode near the frequency, 900MHz. The feature of this type is to reduce the volume effectually. This antenna can not only cover GSM900/DCS/PCS/UMTS operation but maintain good radiation efficiency. Finally, we will compare three antennas, and develop procedure with industrial view, and propose the prospect of the GSM/GPRS antenna in PND, as a conclusion.

By time-varying filtering, we realize the signal selectivity and interference suppression, especially for the signals with time-varying power spectrum. It is shown herein that conventional eigenstructure based methods are lower dimensional special case of the time-frequency subspace fitting method. The closed-form array response estimation algorithms for blind source separation in wireless communication is also developed in the dissertation by exploiting the data structure of second-order statistics of the array output in the presence of multipath. The proposed method achieves array response estimation with little constraint on signal property and propagation environment such as scatters or angular spread. Moreover, the array utilized here can be of arbitrary geometry and even uncalibrated. Since the closed-form solution is obtained, no misconvergency may occur and large amount of computation can be saved. The equivalent feed model and corresponding optimization designation are proposed to realize the downlink multi-user selective transmission. By coherent and non-coherent superposition of the electromagnetical field, multiple beams can be formed using a single array, so that each co-channel user signal is transmitted in each beam and will not interfered with each other. The proposed system scheme implements the digital beamforming and the channel allocation in the base band, therefore is suitable for the utilization of the radio software technology. The feasibility and effectiveness of the proposed model are proved by the RF experiment.

To obtain precise result, itis necessary, in the aspect of hardware, to set up one stable optics system with highSNR, only if so, can we do the measurement with the steady NIR. To do so, we designthe optics system using AOTF, and take some measures to increase the light energyand the system SNR, which includes the three layers structure of the light chamber,the equipments to cover the useless light, polarizing to reduce the influence of 0 gradelight and focalize the light with lens. Apart from the hardware aspect, according to theexperiments, we can see that the different temperatures between at setting up themodels and at predicting the results will affect the prediction results in a way, and theaffection extent will be increased along with the increase of the temperaturedifference. Moreover, the light energy that can be detected will be different with thecontact pressure, and the match of the refractive indexes between the tissue and thesurroundings will enhance the light transmission depth, which will take moreinformation of the tissue. So, during the measurement, we should ensure the sametemperature between measuring and predicting, the same contact pressure at everymeasurement and the match of the indexes between the tissue and the surroundings aspossible as we can.
要提高测量精度,从硬件方面就必须有一个稳定的、信噪比较高的分光光路系统,以此得到稳定的近红外光来进行无创检测,针对这个目的,我们设计了 AOTF 分光光路系统,并在系统中采用一定的措施如三层灯室结构、遮光筒以减小杂散光、起偏和检偏来减小 0 级光影响、透镜汇聚等等来提高出射光的能量和系统的信噪比;从其他影响因素方面,通过实验,我们得到不同的建模温度对于预测结果有一定的影响,且影响随着温度的差值越大而越大,另外散反射光谱的能量也随着接触压力的不同而不同,组织的折射率与环境匹配将加大光的入射深度,从而能携带更多的组织信息,所以在测量时我们尽可能保证同一温度、保证同一接触压力以及利用物理或者化学的方法使组织与环境折射率匹配等。

Dye can bring a little color to life, most clothing is color with dyes, modern manufacture dyes can be costly, natural dyes from plan t and animal products have been used since ancient times, so this week, we describe by natural way to dye world, the advice comes from information written by Jenny Tim of the intermedial technology development group in Briton, this anti group is now called practical action, there are several messages to put dye onto material, the vent message for example, can be used to dye wool with onion skins, for this example, use 100 grams of natural wool, the wool must be clean, leave it overnight in water and liquid soap, then wash it with clean water that is a little warm, gently out the water, a solution called a moderant is used in the dying process, a moderant helps fix the dye to the material, traditionally moderants were found in nature, wood ash is one of example, but chemical moderants such as ironare popular today, iron is so would in many stores, it is often mixed with queen of daughter, a finding powder commonly used in cooking.
使用染料可以为生活带来更多的色彩。许多的布料都是通过染料来上色的。现代工业制造的染料通常都非常的贵,从古时起,人们就知道从植物或者动物产品中提取天然染料。这周,我们就来讨论一下如何用天然的方法来给羊毛着色。这一建议来自英国中级技术发展组的Jenny Dean的信息。这一古老贫穷的小组现在被称为实用性活动。把染料加到材料上有几种方法。其中之一是大桶法。举例来说,就是用洋葱皮来染羊毛。这一例子中,用100g的天然羊毛。羊毛必须清洗。用液体肥皂浸泡过夜。然后用温的干净的水冲洗它。轻柔地把多余的水分压挤出来。一种叫做媒染的溶剂也用于染洗过程。媒染是用来固定染料和材料的。传统的方法是,媒染是来天然的,比如木灰。但是像明矾这样的化学媒染在今天也是很流行的。明矾在许多商场都有出售。它通常和一种经常被用于烹调的粉状物-酒石混在一起。我们用多一点点的辛苦,来交换多一点点的幸福
