查询词典 direction finding

Each cell was mapped by the center point on the cell of transverse section with extended up and down for four pixel (nine-pixel lengths in total) and two pixels in width, and thereafter line convoluted dot map was obtained. Through Fourier transformation, the frequency distribution of power spectrum pattern from both horizontal and vertical direction was obtained, and the cell diameter in radius and tangential direction was known from the maximum value except 0 in the distribution.

把每个纤维细胞都用其中心的一个长9个像素点、宽2个像素点的线段点图表示，进行傅立叶变换，其能量光谱图在水平和垂直方向上的频率分布，除零值以外的最大值，即为细胞径向、弦向直径。

In order to know the effects of mulch-drip irrigation on soil enzyme activities of saline-sodic soil with shallow water table, activities of alkaline phosphatase, urease, and invertase around the dripper, within 30 cm in horizontal direction and 40 cm in vertical direction from the dripper during the reclamation process, were investigated. Changes and distribution of soil enzyme activities, also their relationships with principal soil environment factors were studied.

为了解地下水浅埋区重度盐碱地覆膜滴灌对土壤酶活性的影响，测定了重度盐碱地在滴灌利用过程中距离滴头不同水平位置（0～30 cm）和垂直深度（0～40 cm）的土壤碱性磷酸酶、脲酶和蔗糖酶活性，并对土壤酶活性的变化、空间分布特征及与土壤环境因子之间的相关关系进行分析。

It is the basis for designing balance mass. And, the couple between flexure and torsional vibration is calculated, which is QRSs intrinsic zero drift, and is also main considerations of determining scale factor.(3) There is a difference for equivalent elastic compliance constant of quartz crystal between the X-direction and the Z-direction. It is related directly to each parameter of QRS.

2对由机械耦合产生的零漂作了系统的定量描述，指出质量不平衡等因素产生的零漂可以由加质量和去质量来消除，这是我们设计平衡质量的依据；同时，计算了弯曲振动和扭转振动之间的耦合，指出它是QRS的固有零漂，也是确定QRS标度因子时所必须考虑的主要因素之一。

The exchange of the electrovalence of the cupric ion has been testified by XPS-ESCA.Graphite and chloride in the stage structure,seem to be the conductor and insulator,which form the "sandwich" structure.This special structure produced a weak chemical bond belt and provided the carrier space in the perpendicular direction to the c-axis.These factors in and vertical to the direction of c-axis together increased the electrical properties.

GICs将良导体的石墨层与绝缘体的氯化物层在分子尺度上结合起来，所形成的阶结构相当于许多导体和绝缘体层组成的"三明治"结构，产生化学键薄弱的通道，提供了垂直c轴方向的载流子通道，隧道效应和格架空间提供了载流子活动空间，这些因素共同作用使得GICs的电导率成倍增加

It indicates that the extinction capability and concentration of bubble solvent can seriously influence the light absorption in some wavebands, bubbles can change the direction of light propagation and reduce the energy density, the transmission intensity and light energy decrease rapidly with the increase of times that the light passes through the bubbles, and bubbles′ floating nature can cause the uncertainty in the emergent ray direction and energy distribution.

结果显示：泡沫溶液的溶质/溶剂的消光能力、浓度等对特定波段光波的吸收产生关键影响；泡沫通过改变光线的传播方向，大大分散出射光线的能量密度；随着光线穿过泡沫液膜界面的次数增多，透射光强迅速衰减，透射能量迅速下降；其漂浮运动还将导致出射光线方向和能量密度分布的不确定性。

However the available direction estimation region is only within the 3dB beam width of subarrays,in order to estimate at any interested direction one can combine this method with beam scanning.

但其有效的方向估计范围只在子阵的3dB波束宽度内，然而与波束扫描相结合可实现任意空间范围内的方向估计。

On a certain direction the change of energy spectrums relates closedly to the exchange integral in the direction.

沿某一方向能谱的变化与此方向上交换积分的变化密切相关。

"It is nice to know that the market does not only go in one direction when that one direction seems to be down," said Michael Farr,Washington-based market analyst.

"这是很好的了解，市场并不只在一个方向走时，一个方向，似乎是下来，说："迈克尔法尔，华盛顿的市场分析师。

This strategy, the self-adaptation improved strategy for GA based on the probabilistic feasible direction cones , is put forward in the direction of searching for the first time.

本文将遗传算法运用于M〓RIDP优化问题中，在搜索方向上首次提出了一种改进的基于自适应概率可行方向锥的遗传算法。

Direct method is to select the direction of the decline and fall directly point to determine whether the region, where feasible, the commonly used method: random bound by the direction of law, complex method, and so on.

直接法是在选取下降方向和下降点时直接判断是否在可行区域内，常用的方法有：约束随机方向法、复合形法等。

The system can be widely used in belt weighing and batching process control,etc.

介绍了基于智能模糊控制的嵌入式配料系统的设计方法，对模糊PID控制过程和系统调零作了重点的讨论，同时给出了PID控制的程序流程图和系统定长调零子程序。

"I dunno," she answered,"but if you show me aroun', I'll recognize it from the lighthouse just outside the porthole."

"我不知道，"她回答说，"如果你能带我转转，我能认出来的，因为灯塔就在舷窗外。"
