The main object of this research is to investigate synthesis of Cu23Cl Cu and CuO nanoparticles through electrospinning and heat-treated method The research is mainly focused on preparative parameter and the change of heat-treated temperature to form the nanoparticles inlaid in silicon fibers the shape and color change are dicussed First of all to prepare the Polyvinyl butyral and silica dioxide complex nanofiber by electrospinning and then to investigate different heat-treated temperature and reactive time to being an influence on the products The results detected by SEM XRD TEM EDS FTIR combined sol-gel process and electrospinning can prepare Polyvinyl butyral and silica complex nanofiber The experimental result is found when heat-treated temperature is 100~4750C it can produce Cu23Cl nanoparticles; Above 4750C~ 4900C it can produce Cu nanoparticles; Above 450~7000C it can produce CuO nanoparticles And the viscosity is lain between 20~40cp and the sol-gel process time is 3hr it can produce the thinner fibers The average diameter of the fibers are 107 88±21 01nm;Due to the nanoparticles inlaid in the silica fibers the thinner fibers can be inlaid the smaller nanoparticles so this is the result that the experiment is expected To calcine the complex fibers is to produce surface silica fibers contain Cu23Cl Cu and CuO nanoparticles due to surface plasma resonance it make the color of the fibers become yellowish green from light white green turn into the red nuclear finally As the experimental result to utilize sol-gel process combine electrospinning can produce porous silica fibers contain Cu23Cl Cu and CuO nanoparticles

本研究旨在探讨「利用放电纺丝和热处理法来合成Cu23Cl、Cu和CuO奈米粒」之研究，实验著重在制备参数与热处理温度变化对所形成的奈米粒镶嵌在二氧化矽纤维中的形态与颜色变化探讨。首先，利用放电纺丝法制备出聚乙烯醇缩丁醛及二氧化矽之奈米纤维，比较不同的热处理温度与反应时间的改变对产物生成产生影响，进而研究不同热处理温度和时间对生成奈米粒的影响。产物经由SEM、XRD、TEM、EDS和FTIR等仪器分析结果显示，结合溶胶-凝胶法(sol-gel process)和放电纺丝法可产生聚乙烯醇缩丁醛及二氧化矽复合奈米纤维。实验结果发现，若热处理温度在100~4750C下可得到Cu23Cl奈米粒，475~4900C 可得Cu奈米粒，450~7000C以上可得 CuO奈米粒。而黏度介於20~40cp间和溶胶-凝胶时间为3hr时，可产生直径比较细的纤维，纤维直径为107 88±21 01nm；且由於奈米金属颗粒镶嵌在二氧化矽纤维中，直径比较细的纤维，可以得到比较小的奈米金属颗粒，这与实验预期相符。而锻烧此复合物产生多孔的二氧化矽纤维并包含Cu23Cl、Cu和CuO奈米微粒时，由於表面电浆子共震关系，而使纤维颜色由淡白黄绿色变成黄绿色，再变红褐色。由实验结果得知，利用溶胶-凝胶法(sol-gel process)结合放电纺丝法和不同热处理温度，可产生Cu23Cl、Cu和CuO奈米粒镶嵌在二氧化矽纤维。

One type of formula investing, called dollar cost averaging, involves putting the same amount of money into a stock or mutual fund at regular intervals, so that more shares will be bought when the price is low and less when the price is high.

有一种程式投资叫美元成本平均法，按均匀的价格间隔，用相同的资金投资于一种股票，或者一个共同基金的股份；当股价处于低位时买得多，当股价处于高位时买得少。

Since the Chinese authorities seems to be practicing more glasnost with respect to the Sichuan quake than any previous natural or manmade disaster, we'll probably know the facts down the road a bit.

在处理四川地震时，中国当局比以往处理自然或人为灾害时要开放得多。因此我们可能逐渐了解实情。但常去中国的人不禁思考，史上增长最快的经济步伐和建造得太快以致于无法经受时间和自然考验的建筑之间是否有很强的联系。

There is something strange to me, even now, in the reflection that he never saw me; and something stranger yet in the shadowy remembrance that I have of my first childish associations with his white grave-stone in the churchyard, and of the indefinable compassion I used to feel for it lying out alone there in the dark night, when our little parlour was warm and bright with fire and candle, and the doors of our house were - almost cruelly, it seemed to me sometimes - bolted and locked against it.

而当回忆朦胧旧事时，更令我觉得奇怪的是，他那块白灰色的墓石竟是我儿时最初产生的联想，每当我们的小客厅被火炉烧得暖烘烘，又被烛光照得亮堂堂时，我就对独自躺在黑夜里的父亲无限同情，想到他竟被我们关在门外，我简直觉得残忍不堪。

Juliana: It has also been found that women tend to laugh more wildly with men and men tend to laugh more with their buddies.

朱莉安娜：也有人发现女性往往和男性在一起时笑得更疯狂，男人则通常和哥儿们在一起时笑得更多。

The more you learn,the more you earn,said the pop singer Cyndi Lauper as she accepted her high school diploma at the age of 35!

But now, when, as I have said, I began to beweary of the fruitless excursion which I had made so long and sofar every morning in vain, so my opinion of the action itself beganto alter; and I began, with cooler and calmer thoughts, to considerwhat I was going to engage in; what authority or call I had topretend to be judge and executioner upon these men as criminals,whom Heaven had thought fit for so many ages to suffer unpunishedto go on, and to be as it were the executioners of His judgmentsone upon another; how far these people were offenders against me,and what right I had to engage in the quarrel of that blood whichthey shed promiscuously upon one another.

星期五在小船上打死打伤的那五个，情形也一样。他们中有三个确实是受了伤倒下的，另外两个却是吓昏了倒下的。这时候，我手上仍拿着一支枪，但我没有开枪，因为我已把手枪和腰刀给了那西班牙人，手里得留一支装好弹药的枪，以防万一。我把星期五叫过来，吩咐他赶快跑到我们第一次放枪的那棵大树边，把那几支枪拿过来。他一下子就取回来了。于是我把自己的短枪交给他，自己坐下来给所有的枪再次装上弹药，并告诉他需要用枪时随时可来龋正当我在装弹药时，忽然发现那个西班牙人正和一个野人扭作一团，打得不可开交。那个野人手里拿着一把木头刀跟西班牙人拼杀。

Less elaborate versions may be worn at semi-formal occasions when gentlemen are in dark suits .

当在半正式场合，男士穿暗色套装时，女士服装得少一些装饰；当男士穿商务套装时，女士也得穿套装服饰或者"Good Afternoon"服装。

It is also shown that under the same conditions, the values of the LWI gain with incoherent pumping are evidently larger than those without incoherent pumping exceptΦ=0 and the time reaching the steady state is shorter; varying the initial condition doesn't change the stationary value of the LWI gain but can remarkably affect the transient evolution process of the LWI gain.

研究还表明，与不存在非相干泵浦时相比，除了相对位相Φ=0的情况外当存在非相干泵浦时系统可得到大得多的稳态增益，而达到稳态所需的演化时间也短得多；初始条件的变化不改变稳态增益的大小但对瞬态演化过程有明显的影响。

As citizens become depersonalized, they demand richer forms of justification from the administrative state. As the state cannot meet those justificatory demands, citizens become even more alienated.

当公民变得去个人化时，他们会从「行政国」中要求更丰富的合法性形式，当国家无法符合那些合法性需求时，公民则会变得更加异化。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
