Summed up an experience to what we make network sale so, must not regarding SEO as is the only work of network sale, SEO has been done really the effect is very apparent, your cause client the finds you through searching engine website with can special accurate spirit, change rate is average taller, the ad that more beautiful than you even money buys is changed rate is even high, and the can very good product network brand that promotes you, but his turn a sex changeably too strong.

这样给我们做网络营销的总结了一个经验，千万不要把SEO当成是网络营销的唯一工作，SEO做好了的确效果非常明显，你的目标客户都能非常精准的通过搜索引擎找到你的网站，转化率一般都比较高，甚至比你花钱买的广告转化率还要高，而且能很好的提升你的产品网络品牌，但他的可变化性太强了。

引言随着生产技术的发展，现代工业对于X射线的自动检测与识别的需求越来越迫切，而要实现它的关键是如何将缺陷及反映缺陷特征的信息从图像中提取出来，并给予正确的解释。

Due to the fact that the intercarrier spacing in OFDM is relatively small, OFDM transceivers are somewhat more sensitive to phase noise compared to single carrier transceivers. Thus this problem must be carefully considered in designing an OFDMbased system since an accurate prediction of the tolerable phase noise can allow designer to relax system specifications. According to spectrum theorem, two components of phase noise were analyzed: common phase error and intercarrier interference. On the basis of the analysis, the performance of OFDM was given for the case where phase noise has been added to the signal, and an optimal design criterion for OFDM parameters was proposed that allows to improve the phase noise error correcting capabilities in OFDM receiver.

由于采用子载波间相互正交的结构，OFDM系统对于由本地振荡器不稳定性所导致的相位噪声影响非常敏感，针对公共相位误差CPE和载波间干扰ICI两种影响表现形式不同的干扰项，从功率谱密度函数这一独特角度分析了相位噪声对OFDM系统性能的影响，提出了旨在提高接收机抵抗相位噪声能力的OFDM系统关键参数优化与设计准则，可在对所设计OFDM系统性能加以提高的同时，有效降低对接收机前端模拟振荡器件和相位噪声抑制单元的性能指标要求，从而降低接收机硬件实现成本。

Secondly, there are bigger value at risk by Historical Simulation Method of risk-factors free, represented investitive net value are NT 10,000,000, maximum loss of 5﹪probability will greater than NT 2,816,827 or NT 2,344,946. So used considering VAR－Bootstrap of risk factors were more appropriated model, because model of considering risk factors were able to accurate estimate reality value at risk.

二、以未考量风险因子之历史模拟法及GARCH－拔靴法所估计风险值较大，表示投资净值一千万，有5﹪的机率可能的最大损失会大於2，816，827元或2，344，946元，因此，考量风险因子之VAR模型－拔靴法为较适当之模型，因有考量影响风险之因子，较能准确估计出实际之风险值。

The amplitude information is an important parameter in seismic data processing and interpretation. Lithologic research of reservoirs needs an accurate amplitude information, so it is significant to pay more attention to the study of preserved amplitude processing.

地震资料的振幅信息是数据处理和解释的一个重要参数，储层的岩性研究要求对振幅信息进行更精确的处理，地震资料的保幅性具有重要的意义。

The main conclusions are: Mexican hat wavelet is anisotropic one, and it could detect pointlike singularities very efficiently. Morlet and Cauchy wavelet could be used to detect specific directions, and Cauchy wavelet has better direction selectivity than Morlet one. And it has been used to separate the wave field of Ricker. Its results are basically accurate and computation is more efficient.

主要结论有：Mexcian帽小波是各向同性的，主要用来检测点状信号分量，Morlet小波和Cauchy小波主要用来检测方向信号分量，并且Cauchy小波比Morlet小波的方向性要好，检测结果的分辨率要高；利用二维连续小波反变换，以合成的Ricker子波为模拟信号为例进行波场分离，提高了运算效率，实验结果基本上比较准确，还需要实际地震信号的进一步验证。

The spiral CT of three-dimensional SSD and VRT reconstruction provide more clear image on the details of pelvic tumors,which can stereoscopically,easily,understandably display the relationship between the lesion and surrounding structure,and the excisional range,so it can help clinical doctors for accurate diagnosis and making operation plan.

螺旋CT三维表面SSD及VRT图像清晰地显示了术前骨盆肿瘤的细节，以最易理解的形式立体直观地显示了病变及与周围结构的关系及手术应切除的范围，有助于术前正确诊断和制定手术计划，有效地减少术后局部复发。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
