为了更好地将加布莱克曼-哈里斯(Blackman-harris)窗插值谐波分析法用于介损角测量,仿真分析了该算法及其在信号频率、3次谐波、直流分量、采样频率、A/D量化位数、采样时间长度、介损角真实值、白噪声及脉冲噪声变化时计算所得介损角误差的变化。仿真结果表明,频率波动时算法误差很小且稳定;算法随3次谐波分量的增加误差有很微小的增加;算法随直流分量的增加变化不显著;算法随A/D量化位数的增加误差减少,≥10位的量化位数能满足精度要求;随采样频率的增加误差稍有下降,但趋势不明显;随采样长度增加误差减少,0.1s的采样时间长度足够;介损角误差与真实值的关系不大;随白噪声和脉冲噪声含量的减少误差减少,对白噪声和脉冲噪声信噪比约80 dB能满足要求。

为解决非整周期采样时改进的容性电流补偿法存在频谱泄漏和栅栏效应而影响算得的阻性电流准确性的问题,提出了基于加Blackman-harris窗插值的改进容性电流补偿法,有效减轻了非整周期采样给阻性电流测量造成的误差。比较仿真模型给出的原算法和改进算法所得阻性电流基波和3次谐波分量的误差表明,新算法的误差仅为原算法的几分之一到几万分之一测量的准确大为提高。

Studies of e^+e~→D_s^+■^((*)0)K^-and the P-wave charmed-strange mesons are performed based on an e^+e^-collision data sample corresponding to an integrated luminosity of 567 pb^(-1) collected with the BESIII detector at s^(1/2)=4.600 GeV. The processes of e^+e^-→D_s^+■^(*0)K^- and D_s^+■~0K^- are observed for the first time and are found to be dominated by the modes D_s^+D_(s1)(2536)^-and D_s^+D_(s2)~*(2573)^-, respectively. The Born cross sections are measured to be σ~B(e^+e^-→D_s^+■^(*0)K^-) =(10.1±2.3±0.8) pb and σ~B(e^+e^-→D_s^+■~0K^-) =(19.4±2.3± 1.6) pb, and the products of Born cross section and the decay branching fraction are measured to be σ~B(e^+e^-→D_s^+D_(s1)(2536)^-+c.c.)·B(D_(s1)(2536)^-→■^(*0)K^-)=(7.5±1.8±0.7) pb and σ~B(e^+e^-→D_s^+D_(s2)~*(2573)^-+ c.c.)·B(D_(s2)~*(2573)^-→■~0 K^-)=(19.7 ± 2.9 ±2.0) pb. For the D_(s1)(2536)^-and D_(s2)~*(2573)^-mesons, the masses and widths are measured to be M(D_(s1)(2536)^-)=(2537.7±0.5 ±3.1) MeV/c2, Γ(D_(s1)(2536)^-) =(1.7 ±1.2 ±0.6)MeV, and M(D_(s2)~*(2573)^-)=(2570.7±2.0 ±1.7) MeV/c^2, Γ(D_(s2)~*(2573)^-)=(17.2 ±3.6 ±1.1) MeV. The spin-parity of the D_(s2)~*(2573)^-meson is determined to be J^p= 2^+. In addition, the processes e^+e^-→D_s^+■^((*)0)K^-are searched for using the data samples taken at four(two) center-of-mass energies between 4.416(4.527) and 4.575 GeV, and upper limits at the 90% confidence level on the cross sections are determined.

近年来,人们愈发关注公共卫生,以及因洪水灾害和环境污染而产生的有毒物质的迁移与转化问题。设计规划人员也一直在努力探索能够有效应对此类问题的解决方案,期望通过合适的定量方法评估相关方案的影响。本文以美国威明顿市布兰迪万溪周边一处面积约为52.6hm~2的场地为例,识别了场地所在街区当前面临的问题和需求:自20世纪中叶以来,场地经历了高度的工业化发展,除洪水威胁外,附近工业用地、棕地及合流污水管道中的污染物也会随洪水迁移至场地中,极大影响了人们的健康和生活质量。鉴于此,项目团队开发了一套分阶段实施的总体规划方案,以期减少雨洪径流并去除污染物,同时将场地中现有的棕地改造为环境优美的绿地,鼓励更具韧性的场地开发举措。具体设计策略分为地形重塑、引入绿色基础设施和清除污染物三个步骤。方案计划将场地划分为废水处理及颜料制造区、商业区、艺术家聚集区和滨河绿地四个区域,各区域采取不同的污水处理和洪水缓解策略。此外,项目还期望通过增加住宅类型及居住人口的多样性,增进公众与布兰迪万溪的互动。而后,项目应用长期水文影响评价(l-THIA)模型来衡量设计方案的影响和绩效。l-THIA模型是一种空间建模工具,可以估算以往或未来开发方案中雨水补给、雨水径流和非点源污染量的变化。项目利用l-THIA模型评估土地利用现状、城市现行土地利用规划及本研究中提出的总体规划方案的土地利用和污染物清除情况,即将不同区域的土地利用类型及其面积和相关土壤类型输入l-THIA模型中,估算不同污染物的负荷。结果显示,相较土地利用现状,本项目提出的总体规划方案能够更有效地减少雨水径流和污染负荷--雨水径流将减少约24.35%,污染物去除量将增加38.08%。
