恰好

We use the data from BHP company in 1995-2001 and calculate the implied volatility. By comparing the implied volatility calculated from actual option price and the assumed volatility in the model, it is found that Black-Scholes Model does underprice the Out-of-The-Money options and overprice the In-The-Money options because of the wrong assumption on the volatility.

本文选择了澳大利亚BHP公司1995年-2001年其中五年的数据，从实际期权价格中计算得到隐含波动率，并把其与Black-Scholes模型中的假设波动率进行比较，最后可以发现，Black-Scholes模型低估了虚值期权的价格，高估了实值期权的价格，与一般的研究结果恰好相反。

Yet one of the most painful lessons of modern history is the demise of an earlier wave of globalization that coincided with the outbreak of the First World War.

然而我们必须记住那个最惨痛的教训：早期的全球化恰好与第一次世界大战的爆发在同一时间。

Paleoanthropologist David Strait of the University at Albany in New York state and his colleagues found that A. africanus evolved jaws, teeth, and a face that would have been particularly good at withstanding large forces on its premolars—precisely the place where humans and other primates crack large objects, such as nuts that are too big to chew with our molars.

纽约州奥尔巴尼大学古人类学家戴维·斯特雷特和他的同事发现，南方古猿非洲种的颌骨、牙齿和脸经过演化，其前磨牙特别擅长经受极大的力气——人类和其他灵长类动物恰好就用前磨牙来咬碎像坚果一样的大块食物，大到我们的磨牙无法咀嚼。

The condition of the normal eye when parallel rays are focused exactly on the retina and vision is perfect.

This surface works a bit like a giant radio telescope dish in reverse: Rather than focusing parallel astronomical light rays to a point, it collects the scattered plasmons emerging from a tiny sample--positioned strategically near the mirror--and redirects them into a plasmon "beam" in the metallic plane.

这个表面的工作原理相当于一个倒置的巨型射电望远镜的盘面，不同于天文望远镜把平行的天体光线会聚到一点，这一设计起到的作用是收集从一个位置恰好位于像点的微小样品散射出来的等离激元，并把他们重定向成金属平面上的一个等离激元束。

The long parallel rays slanting across the top of theabove radio imageare known collectively as theGalactic Center Radio Arcand jut straight out from theGalactic plane.

斜斜穿过上面这张电波影像上方的平行长线，恰好从银河盘面穿出，被称为是银河中心的电波弧。

The method of the component put thehydrophobic property and approximate surface in the same group and other parameter of QSAR in theanother grou. The result proved the above property.

主成分分析将疏水性和近似表面积划分为一组，其它的为另一组，这一分析结论恰好证明上面的性质。

I mixed it together with Frank at Gao Yang's studio, which is called Pavane Studio…there is so so so few decent recording studios left in singapore maann..i tell u…coz of the damn forever falling sales market, coz of mp3s, piracy, china imports, blah blah blah…but not just that laahh, it's also coz of improving technology and lower costs of recording equipment, so most ppl can do a lot of shit at home, but there's just some stuff or sounds u can't get at home

在新加坡，只剩下那么那么那么少的体面的录音室。我告诉你。。。因为这该死的永远下落的销售市场，因为MP3，非法盗录，中国的大量引进，夸夸其谈。。但不仅是那些，也是因为改进技术和录音设备的低成本，如此多的人可以在家做许多无聊的事情，但恰好有一些你在家无法获得的东西或者声音（应该指那些大自然的声音。

In an age when it is difficult to avoid terror take charge of the streets and look fashionable with a PeaceKeeper handbag.

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.
