时相

• Dealing with remote sensing data of different time ( 1987 , 1996 landsat tm , and 2000 china - brazil earth resource satellite ccd ) and using the gis technology , the dissertation extracts the changing information of the desertification . the dissertation makes a dynamic remote sensing analysis on the desertification of the research region , and discusses the temporal and spatial evolving law of the desertification
  在技术上主要采用了1987 、 1996年的陆地卫星tm数据以及2000年中巴资源卫星1号ccd数据三个不同时相的遥感数据进行图像处理，并利用gis较强的空间分析功能，从中提取研究区土地沙漠化的变化信息，同时与研究区的其他信息数据进行叠加分析，探讨了研究区土地沙漠化的时空演化特点。
• This paper summarized the current status of vegetation classification based on rs technology at home and abroad , and pointed out the developing trend as follows : ( 1 ) from single - phase , single - source classification to fusion of multitemporal , multi - source data ; ( 2 ) from single classifier to hybird classifiers ; ( 3 ) from hard classification to soft classification ; ( 4 ) from pixel - based classification to pixel unmixing and object - oriented classification ; ( 5 ) from traditional classification to intelligent classification
  摘要综述了国内外基于遥感技术进行植被分类的研究现状，并提出植被分类的发展趋势： ( 1 )从单时相、单源遥感分类向多时相、多源信息融合发展； ( 2 )从单一分类方法向复合分类方法发展； ( 3 )从“硬”分类向“软”分类方向发展； ( 4 )从基于像元分类向混合像元分解分类和面向对象分类方向发展； ( 5 )从传统分类向智能分类方向发展。
• Tile author holds that tile investigation of the culture - bound meanings of chinese and english lexicons will promote the contrastive study between the sino - english syntaxes , and the final research goal of the sino - english contrastive linguistics should aim at tackling the dialectical relationship between a people ' s language and a people ' s spirit through a contrastive study of the similarities and dissimilarities between two different languages
  只有用科学的语言观指导英汉对比文化语义学的研究，坚持对比语言学的三个特色，即把描写和解释相结合、历时和共时相结合、理论和实践相结合，我们才能取得丰硕的成果。
• At that time , cytosolic fluorescence intensity decreased to normal level , which shows that most of cells get through the gl / s point and enter the log phase . when cultured in medium that neucl was omitted , most of the cells were synchronized at gl stage of cell cycle . with flow cytometry , we found that cytosolic cam content of gl cells was higher than that of normal cells at log stage
  在激光扫描共聚焦显微镜下观察不同周期时相裂殖酵母细胞中cam的浓度及分布变化，结果表明，分裂期细胞总体荧光强度强于间期细胞；而对同一细胞内荧光强度的分析说明，间期细胞的荧光主要分布于胞质中，细胞核内则分布较少；而正在进行有丝分裂的细胞内荧光主要集中于赤道板处；刚完成有丝分裂的细胞内荧光则相对集中于两端或其中的一端。
• Based on two satellite images from landsat tm / etm + , land use types are measured through the method of maximum likelihood classification . land use change areas are determined and extracted by using post - classification comparison . for further study on the time and spatial characteristic of land use change in longhai county from 1989 to 2000 , the mathematical methodologies are established
  因此本文利用1989年和2000年两期的landsattm / etm遥感图像，采用最大似然法的监督分类完成对两个时相各土地利用类型的测量，基于分类后比较法发现和提取土地利用变化信息。
• Result : in each time phase , there was no significant difference between vessels in control group and expriment 1 , both groups showing satisfactory effect in the measurement of oxygen consumption volume and nbt tintation times and examination of histopatholoy and ultrastructural morphology and patency rate of cryopreserved allograft arteries
  结果：在各个时相，实验组i和对照组的nbt染色的时间和氧耗量皆无统计学差异（ p > 0 . 05 ） ，而实验组ii和对照组的nbt染色时间和氧耗量统计学差异显著。
• As training progresses , the patterns of stance becomes more diversified and complex , allowing simultaneous execution of two or more movements from the same position . these develops speed , power and flexibility . for beginners there are taeguk 1 to 8 poomse meaning patterns name after the taeguggi , the same symbols on the korean national flag
  对抗时相方都是直接接触，以刚制刚，用简练硬朗的方法直接击打对方，或拳或腿，速度快，变化多防守的动作也是以直接的格挡为主，随即是连续的反击动作。
