A New Horizon

Beijing Review 2024年第40期67卷 28-29页

作者： Li wenhan 不详

What is the contemporary significance of the concept of human rights?How to grasp its implications?Does this concept still wield influence in safeguarding individualsfundamental needs?Chinese and foreign scholars recently exchanged their ideas on and observations of human rights in China at a January 20 seminar hosted by the China International Communications Group Center for the Americas(CICG Americas)ahead of the fourth cycle of the universal periodic review of China which was launched by the UN Human Rights Council on January 23.

准确地定位稻株是水稻株间除草机械作业的前提,提出了侧位俯拍的图像采集方式获取稻株茎基部图像,采用茎基部分区边缘拟合的方法定位稻株,解决了除草期内水稻冠层接连引起的定位不准确问题。首先分析稻株生长形态,探究侧位俯拍稻株茎基部的相机安装参数设定,以及影响成像质量的相关因素,提出了遮光条件下采集图像的方法,构建了具有遮光功能的图像采集系统;其次采用2G-R-B彩色图像灰度化、自动阈值、形态学操作等方法处理并分割稻株图像,检测茎基部边缘并分析其形态特征,并提出了分区边缘拟合定位方法:划分拟合区间为3个子区间,在子区间内进行边缘拟合,以拟合边缘线段中点坐标均值作为子区间茎基部中点,根据中点拟合茎基部中线,以中线中点作为定位的茎基部中心。最后进行了基于茎基部与冠层的稻株定位精度田间对比试验,结果显示:插秧后10~20 d内,基于茎基部的稻株定位误差均在7.0 mm以下,其中10 d、15 d、20 d时的定位误差分别为6.9mm/6.8 mm、5.9 mm/5.8 mm、6.3 mm/6.5 mm(有水条件/无水条件);基于冠层的稻株定位误差在8.0 mm以上,其中插秧20 d后,定位误差超过15 mm以上。试验结果表明,所提出的基于茎基部分区边缘拟合的稻株定位方法,定位精度高,除草适用期长,可满足株间机械除草过程中对稻株精准定位的技术要求。

This study compared the differences in the wave climate in the South China Sea and North Indian Ocean under these two datasets:ERA-40 wave reanalysis and Mei’s hindcast wave *** the numerical calculation of regional ocean waves,the wave climate characteristics exhibited significant bias if the influence of external swells(swells from afar)was not fully considered,which may provide an incorrect basis for global climate change analysis.1)The trends of the significant wave height(SWH)obtained from the two datasets showed significant differences,such as those of the Bay of Bengal and the Java Sea in *** the past 45 years,SWH from ERA-40(SWH-ERA)exhibited a significant annual increase in low-latitude waters of the North Indian Ocean(0.2-0.6 cm yr^(-1))and South China Sea(0.2-0.8 cm yr^(-1)).2)In the Bay of Bengal,the SWH-ERA in each month was generally 0.5 m higher than the SWH from Mei’s hindcast wave data(SWH-Mei)and can reach 1.0 m higher in some months.3)In the Bay of Bengal,SWH-ERA and SWH-Mei increased significantly at annual rates of 0.13 and 0.27 cm yr^(-1),*** increasing trend was mainly reflected after ***-ERA showed a trough in 1975(1.33 m)and a crest in 1992(1.83 m),which were not reflected in SWH-Mei.
