MSVCOCA¹²⁵⁷⁵⁸BNC⁵⁴⁷⁷⁹ 基本例句 n.载人宇宙飞船¹⁰⁰ The average person in the U. S. receives an effective dose of about3 mSv per year from naturally occurring radioactive materials and cosmic radiation from outer space. 在美国,平均每人收到来自天然存在的放射性材料和来自外太空的宇宙辐射,每年约3毫希沃特有效剂量。 kootinlok The major innovation of this paper is that it estimates the dynamic hedge ratio by DC- MSV model. 文章的主要创新是通过 DC- MSV模型来估计动态的套期保值比率。 fabiao Altitude plays a big role, but the largest source of background radiation comes from radon gas in our homes about2 mSv per year. 海拔起着很大的作用,但天然辐射的最大来源,来自建筑物的氡气每年约2毫希沃特。 kootinlok At the time of the workers’ withdrawal, some part or parts of the plant were emitting10 millisieverts mSv of radiation per hour. 在工作人员的撤离之时,核电厂的某些部分已经以每小时10毫希速度向外泄露核物质了。 ecocn Background radiation delivers the average person a radiation dose of about3 millisieverts mSv a year. 平均每个人一年所接受到的背景辐射量为3豪希弗。 ecocn Chernobyl cataract studies suggest that radiation opacities may occur from doses as low as 250 mSv. 切尔诺贝利的白内障研究表明,250 mSv低剂量辐射可导致辐射性混浊。 who Exposure to350 mSv was the criterion for relocating people after the Chernobyl accident, according to the World Nuclear Association. 根据世界核能协会提供的数据,切尔诺贝利核电站事故发生后,凡辐射标准达到350毫西弗的地区的居民均需重新安置。 www.chinadaily.com.cn Finally, the empirical study shows that the efficiency of DC- MSV model is superior to the current popular hedging models. 三是实证研究表明,文章的模型优于流行的现有研究的套期保值模型。 fabiao However, there are uncertainties concerning the magnitude of the effect, particularly at doses much lower than about100 mSv. 但是,对于影响的强度,特别是在剂量远低于约100mSv时,存在不确定性。 who The fourth chapter takes an empirical study based upon DC- MSV dynamic hedging model, and conducts the contrast research with three commonly used models. 第四章是对基于 DC- MSV的动态套期保值模型进行实证,并与三种常用模型进行对比研究。 fabiao The added dose from cosmic rays during a coast-to-coast round trip flight in a commercial airplane is about 0.03 mSv. 在往返美国东西的一轮商业飞机飞行旅程中多受到0.03毫希来自宇宙射线时剂量。 kootinlok Thirdly, separately construct GARCH- X and DC- MSV model to forecast dynamic hedging ratio. 第三,分别构建了 GARCH- X模型和 DC- MSV模型来预测动态套期保值比率。 www.361xs.com |
