查询词典 sensing

Base on comparison with the remote sensing data in 1982 and 2000 and field investigation, the results of land cover and land use change were obtained by the method of landscape analysis. Ten types of land use were identified: riparian woods, riparian shrubbery, desert shrubbery, desert grassland, river-way and water area, salinised land, town, Gobi, shift sand dune, denudative upland. The results show that,(1) there were obvious changes in land cover structure.

然而通过对植物冠层与辐射相互作用的机理的研究表明，把目标地物作为漫反射体的假设与实际情况相差较大，不尽合理。

Vegetation fractions in different districts of Wuhan were calculated based on remote sensing images (TM images and ETM+ images) in 1988,1991,1996 and 2002 by employing method for dimidiate pixel model,and the vegetation fraction maps of different periods were generated to analysis the temporal change of vegetation fraction of Wuhan area.

The organoboron compounds in this paper are based on triarylboranes, boronic acids and boronic esters. The structure-property relationship and sensing mechanism are elucidated. Organoboron compounds as Lewis acid can be used as fluoride probe with high sensitivity and selectivity because they have a unique LUMO in which the π-conjugation is divergently extended through the vacant p-orbital of the boron atom. The complexation of the boron π-electron systems with fluoride ion would interrupt the π-conjugation extended through the boron atom, causing the change of photophysical properties.

介绍了基于三芳基硼化合物、硼酸和硼酸酯的有机硼化合物在氟离子检测中的应用，评述了这些化合物的结构和检测性能之间的关系，讨论了检测机理，即有机硼化合物中硼原子空的p轨道使其作为路易斯酸能够选择性地结合氟离子，硼原子与氟离子的结合破坏了硼中心与芳香取代基的p-π共轭，引起有机硼化合物光物理性质的变化，从而实现对氟离子的高选择性检测。

Then, the paper extended the signal \| noise model of principal component analysis, proposed the dividable concept of background\|anomaly signal sub\|space of remote sensing image multi\|data set high\|dimensional, and gave the threshold estimated method of sub\|space division.

然后，对主成分分析的信号噪声模型加以引申，提出了遥感图像多元数据集合高维空间的背景异常信号子空间可划分的概念，并给出了子空间划分的阈值估计方法。

全面的安全系统包括遥控中央锁，驶离锁定，超声波入侵传感，射频遥控器和发动机锁止

Based on a rather long temporal series of remote sensing data, employing RS and GIS as its tool and FVC that is of rather high sensitivity over the coverage of vegetation in arid area as its monitoring index of desertification, the dissertation analyzes the features of the dynamitic variation of desertification in Xinjiang over the years by using the slop variation to reflect the features of temporal-spatial distributing and the changes of areas of the desertification in Xinjiang.

以较长时间序列的遥感数据为基础，以RS和GIS为工具，选择了在干旱区对植被覆盖度上有较好敏感性的FVC的斜率作为荒漠化监测指标，利用1982~2000年期间新疆FVC斜率变化来反演新疆土地荒漠化的时空分布、面积变化，分析新疆荒漠化多年来动态变化特征； 3。

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。
