Firstly , evidence from depositional pattern suggests that the hsl has experienced an expansion - contraction circle since the late glacial epoch . the expansion and movement of the hsl or desert in early stage were clearly marked by the presence of paleo - aeoline sands . the occurrence of paleosoal characterized the stabilization and contraction of the hsl and also indicated the activity of pedogenesis on the paleo - aeilian sands 通过系列气候代用指标的分析，首次发现该地区粒度、磁化率指标值在两个大的峰值之间有多个小的峰谷出现，表明了在大的气候变化阶段次一级的暖湿?干冷气候波动，值的进一步做年龄的小尺度高分辨率研究。
This work carries out a temporal - spatial analysis and comparison in facial pattern , grain - size , and susceptibility of the sediments of the hunshandake sandy land ( hsl ) on the basis of studies of more than fifty geological sections , a number of samples collected from surface sands as well as results derived from previous studies . the preliminary results of this work provide new environmental information of the working area , which makes it possible to have a brief discussion about the evolution of the hsl since the late glacial epoch . this work can be summarized as the followings 晚冰期，浑善达克沙地全面扩张，达到了沙漠化最大规模，剖面中的古风成砂是最直接的证据，此时气候干冷；全新世早中期，浑善达克沙地成壤比较好，是一个大面积成壤期，相当于全新世适宜期，此时气候暖湿；全新世晚期，浑善达克沙地沙漠化正过程加强，在沙地各剖面上普遍发育风沙沉积，气温较干冷；目前：浑善达克沙地为另一成壤期，成壤作用相对于适宜期较差，气候干暖。
The hsp70 mrna level in the hepatopancreas of agonal shrimps infected with wssv by feeding was lower remarkably than that of normal shrimps , while no rule of hsp70 transcription was discovered in muscles of shrimps infected with vibrio anguillavium and wssv for different hours by injection 但对经注射wssv病毒及焦传珍编码中国对虾和凡纳对虾一种卜isp70的cona研究博士学位论文鳗弧菌后不同时间的对虾肌肉组织进行hsl770mrna水平检测，未发现两种病原感染不同时间后hsl刃0表达的明显规律。
In this paper , we maimly reseach a retrieval method based on both color feature and texture feature of bmp image . in the deformed hsl color space , we extract a number of colors that can representate the original image exactly . then the texture features are introduced . using above two features vectors , the cbir method try to search similar images in image database 我们在hsl色彩空间提取出能够良好再现原图像主色调的n种颜色，作为图像的颜色特征，利用灰度共生矩阵方法计算图像的四个特征值作为图像的纹理特征。基于图像的上述特征矢量，采用线性加权方式综合颜色特征和纹理特征，实现对图像库中相似图像的检索。
According to principles and human perception of color , a hsl ( hue saturation light ) color space , which is perceptively consistent with human vision , is selected and divided . the similarity between two colors is re - defined in order to accord with human discernment for colors . the method of extending color histogram is presented to match images with different colors 从人类色彩感知的角度出发，研究了用于图象检索的色彩空间，特征提取和相似性度量等问题，将hsl色彩空间进行了划分，对每两种色彩之间的相似度进行了重新定义，便其更好地符合人对图象色彩的辨别能力。
The design of yarn is a rather important tache , it can easy get the yarn ' s math model according to its geometrical structure , the paper has bright forward a quick illumination - rendering method that based on hsl / rgb , the advantage of this rendering method is its speediness compared with the traditional rendering method such as phong - rendering method . random diffuse algorithm can add the effect of 3d of the yarn 根据纱线的结构建立相应的数学模型，本文提出一种基于hsl rgb颜色空间转换的快速光照绘制方法，该方法与传统的光照模型如phong光照模型相比可以在很短的时间内对纱线进行光照效果的处理，加上随机扩散算法，使得绘制出的纱线更具有真实感。
On this basis , the color characteristic in this system we extract is : a 72 bit vector of one dimension by statistical color histogram in hsv space ; a set of color average of sub - images and a set of position of sub - images by dividing the original image and using statistic information of pixels " color ; a set of representative color of an image using a suitable cluster algorithm in the hsl space 基于这方面的考虑，提取图像的颜色特征有：在hsv颜色模型空间中进行颜色直方图统计得到一个72bit一维矢量；将图像在纵横方向进行平均分割，以各个分割快中像素的色彩平均值和分割块在图像中的位置作为图像的像素坐标空间特征；在hsl颜色模型空间，通过适当的聚类分析算法提取出能够代表图像颜色特征的代表色集。
