As the wind turbine height increases,the probability of multiple upward leaders flashes within the wind farm *** this study,an upward lightning flash containing 21 upward positive leaders(UPLs)initiated from different wind turbines in Zhangbei Wind Farm was *** average speed of the UPLs was 1.2×10^(5) m/s,which mostly decreased to zero before reaching the cloud *** four UPLs developed to cloud height,with prolonged periods of bright light on three of them and with a minimum duration of 126 ms.A total of nine return strokes occurred on the other two dissipated leader channels,and the numbers of strokes on the two channels was six and three,*** average interstroke interval for the return strokes was 10.5 *** of these nine return strokes had peak currents smaller than 10 *** high-speed video frames confirmed that competition does exist between the UPLs,and the range of shielding effects increases as the height of the ULs *** effect of fan rotation on the initiation of upward leaders and the shielding effect between the wind turbines and upward leaders are discussed.

乐家是平安时期及其后日本雅乐的传承载体,亦是传承制度。10世纪形成的乐家,是在8世纪模仿唐代所建立的音乐机构管理制度外,又衍生出的以家族为主体的世袭传承制度。自此,拥有较高社会层级的乐人开始具备集管理者、表演者、教学者、记录者、研究者为一体的多元身份。对这些身份,乐人有着强烈的自我认同,旁观者亦对此身份下的行为表示认同。该文对日本古代雅乐诸乐家进行总体关照,以古代乐人谱系及其所记录乐书为基础,解析乐家层级结构及乐人身份认同,探索日本古代雅乐的传承规律。

目的探讨父系母系均突变情况下的双亲鉴定亲权指数（PI）的计算方法。方法本研究首先根据孟德尔遗传定律和突变基础模型，推导双亲鉴定的PI通用公式；其次在通用公式基础上，从子-母-父表型上分析，将父系母系均突变情况归纳为8类，推导该情况下的亲母疑父PI(PIAF)和双亲皆疑PI(PIAP)的分项公式；最后设计模拟实验在EX20试剂盒的19个常染色体基因座上生成10 000个由无关个体组成的父母子，统计符合遗传规律组（c组）、父系或母系单方突变组（s组）和父系母系均突变组（d组）的百分比，分别计算亲母疑父组和双亲皆疑组的PI最小值（min）、最大值（max）和平均数（■），同时计算亲母疑父组和双亲皆疑组的累积亲权指数（CPI）的min、max和几何平均数（Π）。结果本研究推导出父系母系均突变情况下的全部双亲鉴定PI公式。c组、s组和d组PI的min、max和■有“minc>mins>mind,maxc>maxs>maxd,■”的规律。所有模拟案例的CPI均满足排除亲缘关系的条件。结论本文公式可应用于父系母系均突变情况下的双亲鉴定PI计算。

促进数字经济与实体经济深度融合是形成新质生产力、建设现代化产业体系、推动经济高质量发展的关键抓手和重要支撑。本文面向新质生产力的形成需求,基于技术驱动产业融合的视角,利用2012~2021年337个城市1879余万条中国专利申请数据及专利-产业匹配信息,采用专利共分类分析方法,测算中国数字经济与实体经济的融合水平,并从时间、产业、区域、网络四个维度考察数字经济与实体经济的融合特征。研究结果表明:第一,从时间维度来看,中国数字经济与实体经济融合水平整体呈上升趋势,数数融合水平明显高于数实融合水平。第二,从产业维度来看,实体产业方面,具有第三产业、第二产业、第一产业依次递减且非均衡发展的融合特征。数字产业方面,数字产品服务业与实体产业的融合水平最高,且数实融合开始逐渐由产品制造领域的融合向以要素驱动和技术应用为导向的融合转变。第三,从区域维度来看,四大板块、不同城市群以及大中小城市的融合水平均存在明显分化。第四,从网络维度来看,中国数实融合网络具有明显的核心-边缘结构特征,样本期内网络密度由0.204提高至0.254,数实融合仍有较大的产业扩展空间。本文为测算数字经济与实体经济融合提供了新思路,研究结论为推动数实融合以及新质生产力发展提供了有益参考。
