Firstly the basic principle of OFDM and its anti-multi-path-fading are briefly introduced in this paper. Then basing on this point, we researched the basic principle, the coding designing and the algorithm of the signal detection of these MIMO-OFDM systems. At the same time, the performances of STBC-OFDM and SFBC-OFDM were analyzed and simulated under short wave circumstance, and got some useful conclusions, they have certain reference value for more research of short wave communication in future.

本文首先介绍了OFDM系统的基本原理以及它对抗多径的基本原理，然后在此基础上，对其所形成的几种MIMO-OFDM系统的基本工作原理，码字设计以及相应的信号检测算法进行了研究，详细分析研究了STBC-OFDM和SFBC-OFDM系统的性能并在短波信道下对其性能进行了仿真和对比分析，得出了有用的结论，这对以后短波通信的深入研究具有参考价值。

The challenges of these material are screen printing and sintering process. Many long fine patterned lines should be printed on a large piece of glass and sustain a smooth, continuous and uniform line pattern; on the other hand, the sintering process is rapidly increasing sintering temperature to a peak in a short time, then cooling the glass substrate to low temperature under a short time shock.

汽车钢化玻璃除霜加热线，是采用在玻璃基板上印刷银浆，在玻璃的钢化热处理过程中完成银导体膜的烧结附着，由于烧结时间短(总时间250sec)和温度骤变条件相当苛刻，要求导电细线无脱落断线，在功率满足要求的情况下，与外蓄电池连接的电极的焊接及附着强度也有具体要求，另外耐候性及耐擦洗等后步要求也较苛刻。

Be able to be short of cash because of some species cause generally in concerning foreign affairs or foreign nationals negotiation, or be reluctant self true thought to be revealed to others,or in some occasion,a few appear on meeting being able to not answer on and on but cannot but answer, the for a short while unable answer but the problem must answer or, is

涉外谈判中，通常会因某种原因不便或不愿把自己的真实思想暴露给别人，或在某些场合，会出现一些不能直答但又不能不答，或一时无法回答但又必须回答的问题，或为试探对方的意向，这时可以通过运用模糊的语言，即把输出的信息模糊化，避免过于确定，让谈判者进退自如，避免谈判陷入僵局，留下必要的回旋余地。

As a result of short-term market tends to be weak, he said that in the short term stock price box may be the greater shock.

作为短期市场的结果，往往是薄弱的，他说，在短期内股价框可能是更大的冲击。

Third, the main characteristic of the Chinese stock market is" bear is short and bull is long", the stock market only became a growth situation from 1996 to 2001, the continuance is short.

Whether sea-going people were short of money about that time, or were short of faith and preferred cork jackets, I don't know; all I know is, that there was but one solitary bidding, and that was from an attorney connected with the bill-broking business, who offered two pounds in cash, and the balance in sherry, but declined to be guaranteed from drowning on any higher bargain.

至于到底是因为那时节水里来海里去的人们囊中羞涩，还是对那玩意儿信心不足，而更信赖软木救生衣，我不得而知；我唯一知道的是，参与竞购的仅有一人，是一位证券经纪行律师。他只肯出两英镑现金，其余以雪利酒冲抵。任如何向他保证穿上这种救生衣绝不会溺水，他都再不肯多出一个子儿。

Concretely, starting from a short sequence primal masks possessing Hermite interpolation properties, a necessary and sufficient conditions such that primal masks satisfies the preassigned order of sum rules are established, then a dual masks with short support, symmetry and any preassigned order of sum rules is constructed, it follows that two multiscaling functions are obtained and then multiwavelets and dual multiwavelets are derived. From which, a general design framework is obtained for constructing biorthogonal multiwavelets system with multiplicity 2r associated with Hermite interpolation functions.

具体的，从具有Hermite插值性质的短序列尺度符号出发，首先建立它具有指定阶和规则的充要条件，然后构造出短支撑、对称的具有指定阶和规则的对偶尺度符号，从而得到一对对偶的尺度函数，再构造出相应的双正交多小波。

So the X-Force SS is indeed Super-Short , but don't think means the X-Force SS is short on performance. This bow has a scalding fast 330 fps IBO Speed , so you'll be able to set just one or two pins to cover your entire bowhunting range.

因此，对X部队的SS实在是超短期的，但不认为指的 X部队的SS是短期的性能，这船头有一个烫伤的快速330新鲜粮食店，国际文凭组织的速度，使您可以设定只是一个或2针，以支付您的整个bowhunting范围。

In order to improve the high-performance concrete quality of longer brittleness, lower tensile strength, particularly the less descending branch in stress-strain curve compared with that of ordinary concrete. The breakthrough of this thesis lies in the mixture of short carbon fiber. Four factors such as water-binder ratio, volume ratio of short carbon fiber and blending value of high efficiency water-reducing admixture were selected as variable. Experiment was carried out by utilizing uniform design. Regression equation was established by regression analysis of the compression strength and the split tensile strength separately utilizing SPSS software. The process of optimization was obtained with the aid of MATLAB. Finally the optimized ratio was acquired.
