编译是在读懂原文的基础上对原文进行编辑和翻译的过程,功能翻译理论为编译的合理性和必然性提供了理论依据。外宣资料作为一种实用文体,对其的翻译必须考虑译文语体、读者反应和译入语文化等因素,因此编译成为外宣资料翻译的一项重要策略,在翻译过程中也应遵循功能翻译理论的思想。在外宣资料编译过程中可采用增补、删减、重构等方法使译文既能忠实于原文又能达到对外宣传的目的。 相似文献

研究了采用带状电子束的周期加载矩形扩展互作用振荡器,分析该结构的优点、色散特性和耦合阻抗,并利用模拟软件进行了冷腔分析。设计出了工作波长为8mm的腔体结构,分析了工作模式为TM31模的场分布。按照冷腔设计结果进行了PIC粒子模拟,电压为19kV、电流为3A的带状电子束在纵向磁场为0.3T的约束下与腔体中的TM31模电磁波互作用。模拟结果表明,电磁波的输出波频率为37.9GHz,功率为3.5kW,验证了在该结构中带状注与高次模互作用的设计思想。 相似文献

This paper presents a new technique of expanding an abridged life table. This technique is a non‐parametric one, which relates the probabilities of dying of the abridged table to those of a standard complete table. In order to evaluate the accuracy of the new technique we use it, as well as two other techniques, for expanding empirical abridged data sets. According to the results of our calculations the new method proves very efficient in producing complete life tables from grouped data, in many cases producing more accurate results than the other two methods in spite of its simplicity. 相似文献

Proposed in this paper is a technique for estimating, from coarsly grouped empirical death data, the age‐specific numbers of deaths for the elderly population. This question is primarily of interest in countries where the empirical data are available only in a grouped form, given usually in quinquennial age groups and in a large open‐ended interval for the ages 85 and over. The main reason that the official data are given in such a form in some countries of Southern Europe and in the Third World is the existence of heaping in the empirical data, i.e. misstatements in age recording, usually rounding to the nearest integer divisible with five. Our evaluation of the method on Swedish mortality data shows that the technique proposed can be efficiently applied to period mortality data. 相似文献

ABSTRACT The purpose of this article is to explain how to conduct a multinomial logistic regression (MLR) to increase its usage among social work researchers. A challenge for social work researchers carrying out practice-based research is to incorporate statistical analyses that are comprehensible to clinicians. Another challenge is that categorical variables, as opposed to continuous, commonly occur in clinical settings, yet their usage is seldom taught in social work education. This article will discuss MLR, a categorical data analysis used when there are three or more unordered categories in the outcome variable. Multinomial logistic regression determines differences across client groups, and can be useful in assessment, case planning, and examination of outcomes. 相似文献

三维动画虽然很大程度上依赖于技术,但技术无论多么重要它都只是手段而不是目的。依靠技术的手段,在数字媒体上把无形的人类情感用视听艺术的实在形式和艺术语言理性地表现出来,这才是数字艺术的真正追求。三维技术的制作环节可以分为四部分:模型制作、材质与灯光制作、动画制作、后期合成。在这些环节中,它们的关系是相互影响和制约的,技术的提升也受到电脑硬件发展的约束。在动画片制作环节视觉呈现上,我们可以用数字艺术的创作方式及其可依赖的视觉美学原理来指导实践创作。 相似文献

Dual-frame, random-digit-dialing (DFRDD) surveys, using a frame of landline telephone numbers and a frame of cell phone numbers, have become the norm for telephone surveys. Two alternative frame constructions sample exclusively from a cell phone frame, referred to as the ‘single-frame cell,’ and sample from the listed landline frame and the cell phone frame, referred to as ‘listed/cell.’ The listed/cell frame construction differs from the DFRDD in that it does not select unlisted-landline frame members. We observe in our simulated data that the listed/cell frame construction results in estimates that more closely approximate the estimates from DFRDD compared with the single-frame cell, results in an improvement in precision compared with the DFRDD that is not as large as the improvement in the single-frame cell, and has lower cost than both the DFRDD and the single-frame cell. We conclude that a listed/cell frame construction might be a better solution than either a DFRDD or single-frame cell frame construction. 相似文献

Objective: To study red cell distribution width (RDW), RDW to platelet ratio (RPR) and mean platelet volume to platelet ratio (MPR), novel inflammatory markers of routine hemogram, of patients with or without dementia, according to the grade of the disease established by Fazekas’s score in magnetic resonance imaging (MRI).Methods: A total of 1342 cases that undergone cranial MRI study were retrospectively analyzed. Patients without a previous stroke and over 45 years were enrolled in the study. Demographic and laboratory characteristics of the participants were obtained from institutional computerized database. Subcortical and periventricular white matter were evaluated in axial FLAIR images according to Fazekas’s grading scale. Univariate and multivariate analysis were performed for assessing the predictors of Fazekas’s grading scale.Results: MPR of Fazekas 0, Fazekas 1, Fazekas 2 and Fazekas 3 groups were 3, 3, 4 and 3%, respectively. MPR difference between study groups was not significant (p?=?.32). RPR of Fazekas 0, Fazekas 1, Fazekas 2 and Fazekas 3 groups were 6, 7, 7 and 7%, respectively. RPR difference between study groups was significant (p?.001).Conclusion: We suggest that increased RDW and RPR values may indicate higher Fazekas’s score and dementia in cranial imaging studies. The radiologist should pay particular attention in interpretation of cranial MRI of these patients. 相似文献

Two-phase optional randomized response (TORR) technique has been proposed. The proposed randomized response (RR) performs much better in general than the existing RR techniques. Theoretical and numerical illustrations identified conditions of superiority of the proposed TORR over the existing comparable optional randomized response (ORR) techniques. 相似文献
