查询词典 discrepancy

This paper presented two regularization methods to solve this problem in SONAH: the standard Tikhonov procedure accompanied with two parameter selection procedures, the Morozov's discrepancy principle and the Engl's criterion, which were crucial to the regularization.

为此，通过两种不同的正则化方法解决上述问题：第一种方法采用标准的Tikhonov正则算子，并结合需要测量信号先验知识的Morozov偏差原则；第二种方法采用标准的Tikhonov正则算子，并结合不需要测量信号先验知识的Engl误差最小化原则。

We present an inverse method based on Tikhonov regularization theory. A regularized functional is established and regularization parameters are deduced with Arcangeli criterion and Morozov discrepancy principle. The functional is solved by sensitivity coefficients and Newton-Raphson iteration method.

充分考虑非线性瞬态热传导过程测温数据的误差特点，根据Tikhonov正则化理论，构造合适的正则化泛函，利用Arcangeli准则和Morozov偏差原理确定正则参数，采用灵敏度系数和Newton-Raphson迭代法求解该泛函。

The reconstruction problem is ill-posed, so two optimal criterions, the least module and the smoothness criterion base on Tikhonov regularization technique, are introduced into reconstruction algorithm. Many regularization parameters choice strategies are investigated, and the TPA(Two—Parameter Algorithm) strategy which is based on the Morozov discrepancy principles, is implemented in two regularization reconstruction algorithms.Numerical experiment results show that the nonnegative and smoothness constraint condition can overcome the difficulty of iteration semiconvergent, preconditioned technique can improve convergence rate and reconstruction accuracy, smoothness regularization criterion can meliorate ill-posed problem of reconstruction and enhance iteration stability, and the TPA is an effective strategy of regularization parameters choice.

数值试验表明：在共轭梯度法中引入非负约束和光滑约束改善了迭代的"半收敛"性，非负约束保证了解的非负性，光滑约束抑制了重建解的振荡现象，约束算法的重建精度与无约束算法相比大幅度提高；在约束共轭梯度重建算法中引入预优技术，可以加快算法的收敛速度，提高迭代的稳定性和重建精度；引入光滑准则的正则化技术可以有效改善图像重建问题的不适定性，加快迭代的收敛速度，提高迭代的稳定性和图像重建质量，计算正则参数的TPA算法在闪光照相图像重建中是有效的。

The possibility that stellar evolution of either Sirius A or Sirius B could be responsible for this discrepancy is rejected by astronomers on the grounds that the timescale of thousands of years is too short and that there is no sign of the nebulosity in the system that would be expected had such a change taken place.

恒星演化的可能性要么是天狼星A要么是天狼星B造成的差异，地球上科学家不认可这种看法，数千年的时间刻度太短，在系统内没有星云状物的迹象，在这系统内认为这可能性会发生的。

It will further increase the discrepancy between the observed and the predicted neutrino fluxes in Super Kam...

这将进一步增大在SuperKamiokande太阳中微子实验上中微子流强的实验测量值与理论预计值之间的差异。

For example,strict disciplinary division and the structure of knowledge based on curriculum set-up are in discrepancy with the diagnosis of diseases in medical education;the definition of"high quality"medical talents by the guideline in medical education,the emphasis on the social adaptability of medical students upon graduation and the practice of borrowing from the experience in nonmedical education are,to some extent,deviating from the uniqueness of medical education.

在现实社会条件下，医学教育的一些通常做法是违背客观规律的，如严格的"课程"划分以及按课程建立的知识衔接关系并不符合医学实践中认识疾病的一般规律；医学教育指导思想方面对医学人才"高素质"的界定、对医学生毕业即高度适应社会需要的强调、对医学教育充分借鉴某些非医学教育经验的做法，都在一定程度上有违医学教育的特殊规律。

Thanks to the opaqueness and polysemy characteristic of literary language,the discrepancy between source and target languages and cultures,and the subjectivity inherent of the interpretation,literary translation,in the essence,is only a partial one,at its best.

摘 要：思想表达的不充分性源于语言的不完备性，是所谓"道可道，非常道；名可名，非常名"；文学语言表意的不透明性与多意性，翻译所涉语言和文化系统的差异性，以及理解的历史性，决定了——文学：译可译，非常译。
