查询词典 hillside fields

On the one hand, because of the short action time, it is impossible to get enough time to circumvolve instruments or to circumvolve the physical fields being measured so as to scan in all directions, so the physical fields can only be measured through several instruments; on the other hand, because the physical fields are partly screened or the operator domain is too limited, the measurement directions are limited, too.

一方面，因为作用时间短，不可能有充足的时间使仪器旋转或使被测物场旋转来全方位扫描，只能固定几个方位的探头同时进行测量；另一方面，由于物体被部分遮挡或作用域小，使观测方位受到限制，也只能在测量中用少量的探头。

The reasons of our choice are:(1) the coupling of the electromagnetic field with the matter is universal and there is already some experiences with such a kind of field in the literature;(2) the pion is the lightest hadron and its interaction with other fields are known to some extent. The pion fields have been treated as external fields but the discussion is not comprehensive in the literature.

我们选取这样的外场的理由如下：(1)电磁场与物质相互作用的耦合常数是普适的，而且文献中已经有把电磁场当作外场来处理的经验；(2)π介子是最轻的强子，它与其它场的相互作用人们已经有所了解，文献中也有把π介子场当作外场来处理的例子，但讨论还不够深入。

In this paper,the author give the spectra characterizations of nonsigular feedback polynomials and local permutation polynomial s over finite fields and residue class rings,and simplify existing results over prime fields,and provide a new proof method for the spectra characterization of correlation immune functions over finite fields and residue class rings.

本文给出了有限域和剩余类环上非线性反馈移存器的非奇异反馈多项式及局部置换多项式的谱刻划，简化了素域上的现有结果，并对有限域上和剩余类环上相关免疫函数的谱特征给出了一个新的证明方法。

It is shown from this thesis that flow fields on synoptic maps can be decomposed into rotation and deformation fields. Geostrophic non-frictional cyclone and anticyclone vortex patterns are closed circulations around the center point, streamlines of frictional cyclone and anticyclone patterns have spiral forms around the focus point. Saddle fields have four vortex centers (two cyclones and two anticyclones) and a saddle point. Blocking high pressure and cut-off low pressure patterns consist of a vortex center and a saddle point.

本文说明了天气图上的流场可以分解为旋转场和变形场：地转无摩擦的气旋、反气旋的涡旋型式是围绕中心点的闭合环流；考虑摩擦的气旋、反气旋的流型是围绕焦点的螺旋型式；鞍型场有4个涡旋中心点（2个气旋和2个反气旋）与1个鞍点；阻塞高压和切断低压由1个涡旋中心点与1个鞍点组成。

Furthermore, the statistical characteristics of the flow fields at the stator passage are obtained from the data of SPIV measurement, and the turbulence kinematic energy fields and Renold Stress fields are analyzed in primary at both design and near stall conditions.

从SPIV测量结果及CFD数值模拟结果来看，当前的CFD数值模拟技术在模拟真实压气机时，模拟结果总体趋势是正确的，但在具体流动细节上，其计算精度和可靠性还有待于进一步提高。

Comparing the unsteady flow fields obtained by CFD with the measurement results with SPIV, it can be found that the CFD results can capture the main characteristics of the flow fields observed in the experiment results, however, the precision of the CFD needs to be further improved, and to predict the detail flow structures, such as the tip leakage vortex in the compressor rotor, by CFD still has some difficulties, thus, some work should be done to improve the turbulence model for more accuracy prediction of the flow fields by CFD for the complex flow in turbomachinery.

定常计算结果和非定常计算结果都不能很好地反映出转子叶尖泄漏流，转子尾迹和泄漏流在静子通道中的演化，及其与静子的相互作用等复杂流动情况。开展叶轮机适用的湍流模型研究，对于提高叶轮机内部复杂流动数值模拟的准确性具有非常重要的价值。

The velocity fields,pressure fields and stress tensor fields in both of channels are respectively determined.

与挤出螺杆相比，注塑螺杆具有特殊形式的头部结构，这是由注塑机塑化部件的特点决定的。

Some standards prescribe implementation behavior with respect to reserved fields e.g., originators of data structures containing reserved fields must zero fill them; consumers of data structures containing reserved fields must ignore them, etc.

一些标准规定了关于保留字段的实现行为，例如包含保留字段的数据结构的初始化者必须填零；而该数据结构的用户必须忽略保留字段的值。

Because a constructor sets the fields of a new object to zero or empty values before performing other actions, class-type and pointer-type fields in a partially constructed object are always nil. A destructor should therefore check for nil values before operating on class-type or pointer-type fields.

因为构造函数在执行其它动作之前先设置新对象的字段为 0 或空值，在一个只构建了一部分的对象中，类类型和指针类型的字段总是 nil，所以，在操作类类型和指针类型的字段时，析构函数必须检查它们是否为 nil。

Cavitation is the most distinct characteristic of the high-power low-frequency ultrasonic fields, and it is also regarded as the primary mechanism of ultrasonic cleaning. Nevertheless, the measurement question of the high-power low-frequency ultrasonic fields hasn't been resolved well, because of the incomplete cavitation theory and the complexity of cavitation fields. The universal acceptant standard measurement hasn't been found up to the present so that it is difficult to judge of the performance of ultrasonic cleaning machines scientifically.

大功率低频超声场最鲜明的特点就是空化，而空化也被认为是超声清洗的主要物理机制，但由于其理论研究尚不完善，加之空化声场的复杂性，使得至今大功率低频超声场的测量未得到很好的解决，尚未找到一种与清洗效果有确定关系的普遍适用的标准方法，使得在客观地评判清洗机优劣时很困难。

Foods high in this vitamin include oily fish such as salmon, tuna and, and fish liver oils.

维生素D含量高的食物包括诸如大麻哈鱼、金枪鱼和鲭鱼之类的油鱼以及鱼肝油。
