查询词典 approximate differentiability

By using testing functions to make comparative research on the precision of approximate models which were built by RBF under the condition of different sample amounts and different kernel function types, a conclusion was drawn: the model quality built by Reciprocal Multiquadric RBF as kernel function was highest when the sample amout was big, and the model quality built by Gaussian RBF as kernel function was highest when the sample amount was small.

运用测试函数对在不同样本数量与不同核函数形式下所建立的近似模型的精度进行对比研究，得出逆多二次函数与高斯函数作为核函数分别在大样本和小样本情况下精度最高的结论，并验证了径向基函数近似模型方法能够兼顾效率与精度。

It is discussed to recondition the coefficient matrix and to treat the domain with several media.Then external wavelets are used to deal with mixed boundary conditions, which simplifies the disposal of boundary conditions and improves the accuracy of approximate solutions.

讨论了系数矩阵的预处理技术和多介质问题的处理方法；在混合边界条件的处理中使用了外小波，既简化了边界条件的处理，又提高了近似解的精度。

The approximate solution shows that there is a rectilinearity in the pressure and time semilogarithmic coordinates.

注水井压降试井的近似解表明在压力与时间的半对数坐标下呈直线关系，直线的斜率与截距取决于注采比、注采井距、注采厚度比、注采产能系数比等参数。

The approximate date of the redaction of the book and the period of its author's literary activity are somewhat less doubtful.

的大致日期编辑的书籍和作者时期的文学活动是不太令人怀疑。

There was further provision for four notices of "definite"(as opposed to "approximate") redelivery date.

就随后的四次通知采用的"精确"（与此相对应的是"大致"）的还船日期。

The charter party provided for a redelivery date range "minimum September 20 / maximum November 22, 2007" and that "charterers are to give owners not less than 30 days followed by 20, 15, 10, 7 days notice of approximate redelivery date".

租约规定还船期为"最早在9月20日，最晚在11月22日（2007年）"，"承租人在不少于30日及随后20、15、10、7天之前通知船东大致的还船日期"。

The result may seem to be harsh on the owners who made plans in reliance on the first notice, but it would appear that the High Court was persuaded that charterers should not be deprived of the use of the ship for the full charter duration when the 30 day notice of redelivery was expressed to be approximate.

这一结果对于依赖第一次通知而做出计划的船东来讲是很难接受的，高等法院认为承租人在30天还船通知表达为大致时，承租人不能因此而被剥夺全部使用全部租期的权利。

In April of this year the High Court in London held that a time charterers' 30 day approximate notice of redelivery could be revised by him, even though the shipowner was then forced to lose follow-on business fixed in reliance on the first notice.

今年4月，伦敦高等法院判决认定承租人可以修正其关于期租合同的30日预估还船通知，尽管船东因信赖承租人的第一次通知而签订了下一个对其生效的合约。

By means of a resonable and approximate treatment the dependent variables of the integral equation are reduced to depend only on the two coordinates of the wing plane.

通过合理的近似处理，使积分方程的自变量仅依赖于机翼所在平面的两个座标，这就使我们在利用有限无法进行数值解时，只需在机翼平面上划分元素，避免了在流场空间中划分元素的传统作法，从而大大降低了对计算容量的要求和计算工作量，使跨音速三维机翼的气动力计算有可能在较小的计算机(例如709机)上完成。

First introduced the lattice-value information systems knowledge, and to partial order for the basis has been a new relationship: advantage, given the reduction and the core, the concept of simplifying the classification of features, it is also given on the approximation, and the approximate reduction of matrix determined theorem and the concept of identification, the final adoption of specific reduction of examples to illustrate this method is effective.

首先介绍了格值信息系统的相关知识，并以偏序关系为基础得到了一种新的关系：优势关系，给出了约简和核心，简化了概念的分类特征，也给出了上近似、下近似及约简的判定定理和辨识矩阵的概念，最后通过具体的例子说明这种约简方法是有效的。

When this condition occurs, inbound replication with the source partner is stopped on the destination domain controller and event ID 2042 is logged in the Directory Services event log.

计算机密码学是研究计算机信息加密、解密及其变换的科学，是数学和计算机的交义学科，也是一门新兴的学科。
