Yet Dennis cockily said that he slept like a baby during all that volatility.

然而丹尼斯逞能地说他在波动期间睡得像小孩一样。

As can be seen in Fig. 5, dipropyl ether will be recovered in the distillate using 1-pentanol, N,N-dimethylformamide and 2-ethoxyethanol as entrainers and butyl propionate is the only entrainer studied that inverts the volatility of the azeotropic mixture.

从图 5可以看出，使用1-戊醇、N，N-二甲基甲酰胺和2-乙氧基乙醇作为共溶剂时二丙醚将在馏分中回收，丙酸丁酯是唯一与共沸混合物挥发性相反的共溶剂。

Closed, a round fundam ental an nouncements, and at times of e xtreme market volatility.

The results showed that sevoflurane was the most prevalent volatility halogenate anesthetics and had the highest concentration at sampling areas. All study hospitals exceeded the exposure limit for halogenate anesthetics (2ppm) recommended by NIOSH (National Institute for Occupational Safety and Health).The median level of N2O at the two medical centers was 1.87 ppm. Although regional hospitals seldom use N2O, its concentration was very high (median 120.85 ppm).

结果显示，Sevoflurane为使用最多之挥发性卤化麻醉剂，环境浓度亦最高，各医院均有高於NIOSH对於单一卤化麻醉剂暴露建议值(2ppm)的情形；医学中心笑气浓度之中位数为1.87 ppm，然区域医院虽极少使用笑气，环境中位数浓度高达120.85 ppm，有管路或开关阀泄漏之可能性。

This study contributes significantly in financial literatures in describing and modeling volatility in stock markets with incompleted reaction to expected news. It is also of great significance to asset pricing and risk management.

风险和收益是资本市场永恒不变的主题，本研究在波动率研究命题上所作的理论创新和技术应用对于资本市场的证券定价，资产配置以及风险管理同样具有重要的现实指导意义。

In order to achieve a rapid and accurate selection for extractive distillation solvent, and to acquire 1,2,3-trimethylbenzene with high purity from solvent oil via extractive distillation, the UNIFAC model was used to calculate the relative volatility of 1,2,3-trimethylbenzene to indane (the mass ratio of 1,2,3-trimethylbenzene to indane is 4∶1) in five different solvents, acetophenone, di-2-octylhexyl phthalate, glycol, dimethyl sulfoxide,sulfolane at 17.47 kPa.

为了快速准确地选择萃取精馏溶剂，由190#溶剂油萃取精馏获取高纯度连三甲苯，运用UNIFAC模型，计算了质量比为4∶1的连三甲苯-茚满体系在苯乙酮、乙二醇、邻苯二甲酸二辛酯、二甲基亚砜和环丁砜5种溶剂中在17.47 kPa下的相对挥发度。

Al.were studied in the laboratory,and individua l delta-form crystals of antioxidant1010 with good stability,fast drying speed,hi gh purity,heavy bulk density,good flowability,low volatility was obtained.

文摘：在乙醇、低级醇A和水三元混合溶剂中，通过对抗氧剂1010粗品的重结晶精制研究，制备得到了纯度高、堆密度大、流动性好、挥发份低、质量稳定、干燥速度快的δ－型抗氧剂1010。

To improve the empirical performance of the Black-Scholes model, many alternative models have been proposed to address the leptokurtic feature of the asset return distribution, and the effects of volatility clustering phenomenon.

为了改进Black-Scholes模式的实证现象，许多其他的模型被建议有leptokurtic特性以及波动度聚集的现象。

We employ quarterly data on industrial output, indicators of stock market liquidly, stock market volatility, and banking development during 1986:1-2003:3. We found that the Granger causality between output and financial development variables differ significantly among different knowledge intensity industries.

实证方法上，采用Johansen(1992，1995)之最大概似估计法(maximum likelihood estimate， MLE)来检定变数间是否存在共整合关系；若变数间存在共整合关系，则可以向量误差修正模型(vector error correction model，VECM)为基础，据以探讨金融发展与不同知识密度产业经济成长之因果关系。

The system can be widely used in belt weighing and batching process control,etc.

介绍了基于智能模糊控制的嵌入式配料系统的设计方法，对模糊PID控制过程和系统调零作了重点的讨论，同时给出了PID控制的程序流程图和系统定长调零子程序。

"I dunno," she answered,"but if you show me aroun', I'll recognize it from the lighthouse just outside the porthole."

"我不知道，"她回答说，"如果你能带我转转，我能认出来的，因为灯塔就在舷窗外。"
