查询词典 observational error

Using hydrodynamical/N-body simulations and pure dark matter simulations, we found the dark haloes in the first kind of simualtions are more concentrated than in the second kind of simualtions. This result could increase the predicted probability of giant-arcs in gavitational lensing and cancel the great difference between the theoretical and observational results.

用含气体的数值模拟与纯暗物质的数值模拟比较，发现前者暗晕中的暗物质分布比后者中的更加密集，密集参数更大，这可能可以提高理论预言的引力巨弧的概率从而弥补理论与观测结果间的差距。

By analyzing the coupling between magnetic fields and accretion flows we get following results:(1) There should be an upper limit to the magnitude of magnetic field. Under such a case the disk remains Keplerian.(2) The observational distribution of effective temperature might be caused by magnetic diffusion.

对于磁化薄盘，我们的结果归纳起来是二点：(1)磁化薄盘应该有一个上限磁场，在这样的情形之下，磁化盘保持为开普勒盘；(2)观测上的有效温度的分布可能就是由于磁能的耗散而产生。

前扣带回皮质、束旁或背中部丘脑核组成了代表痛苦感的内侧疼痛系统，一旦失活将会大大损害通过观察习得恐惧感的能力，而感觉丘脑核失活则没有影响。

Based on the publicized state informatization quotient,and combining with data that getting from investigation and rational mathematics,firstly it expatiated on which status of Henan information economy in China,by macro,mesne and micro observational granularity Secondly,it is analyzed what is the causes of the current situation according to both comparing with other typical provinces in transverse and tracing development data of Henan information economy in lengthways,in static and dynamic aspects individ...

以国家公布的信息化水平指数体系结构和测评数据为基础，结合调查数据和合理的数理推算，首先从宏观、中观和微观三级粒度阐述了河南省信息经济的地位；而后，从静态和动态两个方面，分别以横向与典型省份比较和纵向追踪河南信息经济历史发展轨迹两种手法分析了形成现有地位的原因；最后得出了政策对信息经济有导向作用，坚持远近效益结合，实现既定目标是可行的结论

Our aim in this observational, prospective, noncontrolled studywas to detect, in 29 patients who underwent abdominal aorticaneurysm surgery, correlations between the incidence ofpostoperative organ failure and intraoperative changes in arterialand portal blood lactate; changes in intramucosal sigmoid pH; differences between sigmoid PCO2 and arterial PCO2 ( CO2);and hemoglobin.

我们在这个观察性、前瞻性、非对照研究中的目的是探求29例腹主动脉瘤手术后患者器官衰竭发生率与术中动脉和门静脉乳酸变化、乙状结肠粘膜内 pH变化、乙状结肠粘膜 PCO2和动脉 PCO2差值（ΔCO2）以及血红蛋白的关系。

The adoption of the International Celestial Reference System and the changes of observational strategy call for the use of departure point on the moving equator independently from Earth's orbital motion. A Nonrotating Origin, proposed by Guinot, is selected.

国际天球参考系的使用、观测精度的提高和方法的改善要求采用与地球轨道运动无关的运动赤道上的起算点， Guinot提出的非旋转原点可作为这样一种选择。
