查询词典 approximates

4Based on a fact that the price formula of Asian options can be transformed into that of vanilla European option when the time to maturity is less than or equal to the length of average, we skillfully obtain the analytical price formula for the option on the minimum or the maximum of two geometric average prices and generalize it to obtain the price formula of several average prices for the first time. We also apply the method of [121], which approximates the arithmetic average by the geometric average, to the pricing of opitons on the minimum or the maximum of two arithmetic average prices to obtain Its approximated price formula. Numerical results show that the approximated price is relatively accurate when the riskless interest rate is large or the option is in the money and the volatility of two underlying assets are high and its accuracy is a little reduced but still good when the dividends are considered. However, it is hardly affected by the sampling number.

我们基于观察到的一个事实即当离到期时间小于或等于平均期间时亚洲期权的价格可变换成普通的欧式期权的价格，从而巧妙地得到了两个几何平均价格的最小或最大值期权价格的解析公式，通过简单地推广，首次得到了多个几何平均时的价格公式；将[121]用于算术平均亚洲期权的定价方法推广到两个算术平均价格的最小或最大值期权，从而得到它的渐进公式，数值结果表明：渐进价格的准确性在无风险利率较大或期权为实值且两标的资产的波动率较小时较好，抽样的个数对它没有影响，但考虑红利时它稍有下降但仍较好。

To view a woman with only erotic eyesight approximates impudicity.

只用色情眼光看女人，近于无耻。

This model,close to experiment,approximates normal model due to the ionization increasing at h...

同时为了充分利用埋沟器件体内沟道的优势，对埋沟掺杂的浓度和深度也进行了合理的设计。

Great differences between them are found in amplitude, and attributed to the strong background wind in troposphere and steady weak wind in lower stratosphere. Steady diurnal variation of temperature appears above 23 km, and the same variation in pressure is found starting from lower altitude, which together suggest a weak diurnal variation in atmosphere density above 23 km, that approximates a constant at each height.

发现风场振幅的变化与统计平均的结果存在较大差异，这归结于当地冬季对流层内强烈变化而低平流层内相对稳定的风场；温度在23 km以上存在稳定的周日变化，气压在更大的范围内存在与温度类似的周日变化，这使得在23 km以上大气密度的周日变化十分微弱，在各个高度上近似为一个常数。

The Brownian network which approximates a two－station multiclass queueing network with dynamic scheduling capability is extended to the case of multistation multiclass manufacturing systems and the appropriate algorithms regarding the input control and sequencing decisions are also developed.

2对于一般结构的制造系统，首次建立了可靠分析的一种线性多变量模型，模型阶数为工作站个数，模型变量为各工作站的实际平均加工时间，由此求得了系统的包括可靠性的稳态运行性能，解决了一般结构的制造系统的性能评估问题。

Noelle models range from a $3,200 basic version to a $20,000 computerized Noelle that best approximates a live birth.

Noelle 孕妇模型的价格从简单型的3200美元到电脑版的2万美元都有，后者和真实分娩最为接近。

By using the first symbol of every observation window as pilot symbols, the transmit efficiency approximates to 1. Moreover, the proposed algorithm does not require the feedback channel. The fast search for the maximum-likelihood solution can be done by sphere decoding aligorthm.

本算法只需获取每个观测窗口的第一个符号，以该符号为导频符号，其传输效率渐近为1，并且不要求系统具有反馈信道，算法中最大似然解的快速搜索可以通过球形译码来实现。

The nearer a society approximates to zero population growth, the olde

一个社会的人口增加率越接近零，其人口便愈老龄化。

This method approximates the nonlinear dynamics efficiently, which is mainly composed of friction in system, by orthogonal polynomials.

该方法利用正交多项式实现对系统中以摩擦力为主的非线性动态充分逼近与补偿，不要求任何摩擦力模型。

Screening will not be discussed here except to say that it approximates grey levels by different size objects (the size of the object is proportional to the grey level) The objects are arranged on in a regular matrix which is at some angle to the horizontal.

普查将不讨论，只是说，它接近不同大小的物体灰色水平（该对象的大小这里是成正比的灰度）的对象是安排在一个普通表，使一些水平角度上。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

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.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
