由于模式误差和初始误差所致,次季节-季节预报技巧整体偏低.国际上多数模式都采用集合预报的方式来提高次季节预报的准确率.热带大气季节内振荡(MJO)作为次季节尺度可预报性的重要来源,其预测水平取决于模式性能和MJO事件本身的物理特性.根据中国气象科学研究院气候系统模式次季节预测系统的回报结果,结合不同类型MJO事件的特征,对模式集合成员间的预报技巧进行了分类和比较.在集合成员预报技巧普遍较高的一类MJO事件中,对流异常信号持续时间较长,强度较大,强对流异常中心主要位于印度洋区域,并逐渐东传至西太平洋.在集合成员预报技巧多数较差的MJO事件中,对流异常信号的强度最弱,维持时间最短.在集合成员预报技巧优劣参半的类别中,MJO往往持续时间较短,强度较低,在后续传播过程中,对流异常中心多停驻在海洋性大陆区域.

针对曲面光学镜片表面缺陷检测精度不高的问题,提出一种基于改进YOLOv5s的曲面光学镜片缺陷检测方法。首先,设计镜片表面缺陷采集装置,并对采集到的缺陷图片进行数据增强以制作镜片缺陷数据集。其次,为了增强YOLOv5s网络对通道信息的利用,在特征提取网络引入SE注意力机制,使网络能够更加准确地提取信息;并在主干网络最后一个C3模块融入Transformer,帮助网络更好地提取全局信息,提高检测效率。最后,考虑到小目标特征信息容易丢失的问题,将主干网络160×160像素的特征层加入颈部的特征融合中,增加网络对浅层信息的利用。改进的YOLOv5s目标检测算法的均值平均精度(mean average precision,mAP)和召回率(recall,R)分别为93.9%和91.6%,比原网络算法分别提高了3.2%和3.4%,表明改进YOLOv5s算法可以有效检测出镜片表面缺陷。

作为当今众多试图超越道德虚无主义的思想家之一的阿格妮丝·赫勒,从追问“好人存在,但好人何以存在”的视角进行了超越道德虚无主义的尝试。在其道德理论中,好人直面并坦然接受现代人双重偶然性存在以及种种悖论,将其生存危机化为转机;好人依据普遍性范畴进行存在的选择,形成统一的道德自我;好人在周围散落的道德规范、规则和价值中,共同确立现代人可以遵循的道德原则、规范和规则等,重新拾起传统的诸多美德。正是基于这一系列行动,好人才存在着。赫勒对此问题的追问与对其答案的探寻,为双重偶然性存在的现代人超越现代道德虚无主义困境提供了一条切实可行的路径。

《花随人聖庵摭憶》續編第八二條梁鼎芬致張之洞函,有“手辦一大賊”“大賊誅除”等語,黃秋岳以為“大賊”必指康有馬,函傣庚子前後,梁鼎芬為警告張之洞勿與自立軍合作、捕殺唐才常同黨而發1,實鶥誤讀。細讀此函,知其作於戊戌年四月,“大賊”當指翁同穌;茅海建先生曾懷疑翁同穌三四月間接連遭遇彈劾另有内幕2,梁函不啻烏幕後運作此次彈劾的一份自供。
