查询词典 vector area

These above problems, which are very important and valuable in agricultural crops area monitoring, are currently less researched. Hence, in this paper, seven types of common texture and five vegetation indices were respectively added into TM multispectral bands to classify using three different methods, which are Minimum Distance, Maximum Likelihood and Support Vector Machine, and analyze the effect on winter wheat identification accuracy by comparing the classification results. The contexture include Mean, Variance, Homogeneity, Contrast, Dissimilarity, Entropy, Variance, Angular Second Moment and Correlation, and the vegetation indices are RVI, SAVI, RDVI, NDWI and SLAVI.

向量场分解是数据可视化领域近几年刚提出的研究课题。

The 3D geologic model constructed by the geotechnical investigation management information system can be used to obtain any desired geologic section in a given area and realize vector filling. It may also cut several cross sections of the geologic body in a given area and visualize the 3D geologic section by turning.

5工程勘察信息系统构造的三维地质模型可以获得指定区域范围内的任意地质剖面图，并实现了矢量填充；可以在指定区域范围内地质体上一次任意剖切出若干个断面，并可以通过旋转观察，实现三维地质剖面的可视化。

Integrating the sound intensity vector on the area which surrounds a sound source gets the sound power of this sound source. Since the integral of the sound power of the sound sources which are not enclosed by the area is zero, one could measure the sound power in ordinary environments correctly by measuring sound intensity.

对于一个声源，只要将其包络面上的声强矢量作积分，就可以求出被围声源的声功率，而测量区域之外的干扰噪声得以抵消，因此可以在普通环境下能准确地测定声源声功率。

In this paper, the rotary spectra of sea current and residual current are calculated for the data of cunent vector time series acquired through a mooring buoy located at (114°20.5'E, 20°04.8'N). Subsequently, the preliminary analysis for the internal structures of current in this area is done from these results of calculation and a lesidual current with a three days period is found in this sea area.

本文利用本所水文气象研究室在东沙群岛西南海域投放的一个锚定浮标(114°20.5′E，20°04.8′N)所获得的一系列海流流速矢量观测资料，用旋转谱分析方法对该站海流的内部结构作初步的探讨，并由此得到该站海流的某些运动学特征。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
