But the attribution reduction is a NP problem,and it needs to be realized by knowledge of elicitation method.

引言粗糙集理论是Pawlak等学者在1982年提出的处理不确定，不精确和不完全数据的一种新的数学工具，主要用于知识的简化及知识依赖性的分析[1]。

Under the assumption that the expected rate μS(t , volatilityσS(t are functions of risk asset S, and stock pricing process respectively driven by a general O-U process and an exponential of a Levy process, we obtain the accurate pricing formulas and put-call parity of European option. In the end, assume that riskless rate is given, we deal with pricing formulas of European option on foreign currency and apply the approach to the pricing of the convertible bond.

利用保险精算方法给出了股票价格遵循广义0一U过程模型的欧式期权的精确定价公式和买权与卖权之间的平价关系以及股票价格过程遵循指数Levy过程的定价模型，最后推导出利率确定情形下外汇期权的定价公式，并且给出了保险精算方法在可转换债券定价中的应用。

During your presurgical eye exam, your eye doctor uses highly specialized instruments to determine which specific areas of your cornea need to be flattened or curved. This allows your eye doctor to chart your eye and remove tissue from your cornea very precisely.

你的眼科医生在手术前的眼睛测试时使用很专业的仪器确定手术面积——需要变平或者变弯的角膜面积，然后绘制你的眼睛图，并且从角膜上精确地移除组织。

Comparing with classical viscoelastic models, fractional derivative models describe not only the constitutive of viscoelastic material and the related mechanics properties accurately in wide range, but also need less model parameters.

分数导数模型与其他经典模型相比不但能够精确地描述粘弹性材料的本构关系及其力学特性，而且确定模型所需实验参数少、能够在较宽的频率范围内描述材料的力学行为。

Both the direct and indirect terrain effects need to be taken in the precise geoid determination of the Western China area.

在确定中国西部精确的重力大地水准面时，直接和间接的地形影响都应该被顾及。

" "Mathematics is ordinarily considered as producing precise and dependable results; but in the stock market the more elaborate and abstruse the mathematics the more uncertain and speculative are the conclusions we draw there from … Whenever calculus is brought in, or higher algebra, you could take it as a warning that the operator was trying to substitute theory for experience, and usually also to give to speculation the deceptive guise of investment.

格雷厄姆对数学在投资中的作用认为数学一般被认为是能產生精确和可信赖的结果。但是在股票市场，所用的数学越复杂深奥，其从中得出的结果也就越不确定，越具有投机性。一旦引入了微积分或者高等代数，你可以把这看作是一个警告，这意味著使用数学者是在用理论代替经验。通常这给了投机欺骗性的偽装，变得好像是投资一样。

Some digital records were obtained from 4 small earthquakes, precise hypocenter locations were determined from arrival times an...

利用这些小地震活动期间所得到的数字记录确定了4次小地震震源的精确位置，利用矩张量反演方法求解了这几个地震的震源机制。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
