Photovolta.c (PV) a.ra.s a.e usua.ly insta.led in open a.ea.; hence, they a.e vulnera.le to lightning strikes tha. ca. result in cell degra.a.ion, complete da.a.e, service disruption, a.d increa.ed ma.ntena.ce costs. a. a.result, it is impera.ive to develop a. effective a.d efficient lightning protection system by eva.ua.ing the tra.sient beha.iour of PV a.ra.s during lightning events. The a.m is to eva.ua.e the tra.sient a.a.ysis of la.ge-sca.e PV systems when subjected to lightning strikes using the finite difference time doma.n (FDTD) technique. Tra.sient overvolta.es a.e ca.cula.ed a. va.ious points within the mounting system. To optimise the FDTD method's execution time a.d ma.e it more suita.le for less powerful ha.dwa.e, a.va.ia.le cell size a.proa.h is employed. Specifica.ly, la.ger cell dimensions a.e used in the ea.thing system a.d sma.ler cell dimensions a.e used in the mounting system. The FDTD method is utilised to ca.cula.e the tempora. va.ia.ion of tra.sient overvolta.es for la.ge-sca.e PV systems under different scena.ios, including va.ia.ions in the striking point, soil resistivity, a.d the presence of a.meta. fra.e. Simula.ion results indica.e tha. the highest tra.sient overvolta.es occur a. the striking point, a.d these va.ues increa.e with the presence of a.PV meta. fra.e a. well a. with higher soil resistivity. Furthermore, a.compa.ison is performed between the overvolta.e results obta.ned from the FDTD a.proa.h a.d the pa.tia. element equiva.ent circuit (PEEC) method a. the four corner points of the mounting systems to demonstra.e the superior a.cura.y of the FDTD method. Besides, a.la.ora.ory experiment is conducted on a.sma.l-sca.e PV system to va.ida.e the simula.ion results. The ca.cula.ed overvolta.es obta.ned from the FDTD a.d PEEC methods a.e compa.ed with the mea.ured va.ues, yielding a.mea. a.solute error of 5% a.d 11% for the FDTD a.d PEEC methods, respectively, thereby confirming the a.cura.y of the FDTD simula.ion model.

短吻三线舌鳎、褐斑三线舌鳎和紫斑舌鳎种类的有效性厘定

水产学报 2024年第3期48卷 109-117页

作者：孔晓瑜罗海容 THOMa. a. Munroe 中国科学院南海海洋研究所中国科学院热带海洋生物资源与生态重点实验室广东省应用海洋生物学重点实验室美国史密斯自然博物馆国家系统研究室

舌鳎属有些种类形态特征高度相似，导致了鉴定困难和种类的混乱，例如短吻三线舌鳎(Cynoglossusa.brevia.us, Gra., 1834)、褐斑三线舌鳎(C. trigra.mus, Günther,1862)和紫斑舌鳎(C. purpureoma.ula.us,Rega.,1905)的种类有效性和种间关系就存在三种观点：仅短吻三线舌鳎为有效种；短吻三线舌鳎和褐斑三线舌鳎均为有效种，而紫斑舌鳎是褐斑三线舌鳎的次同物异名；三个名义种均为有效种。为了解决这一分类混乱，本研究对三种舌鳎的原始描述、自测的模式标本和中国大陆沿海采集标本的28个形态特征和分子条形码进行了比较分析。结果显示，8个可数和16个可量特征的比例值以及2个描述性状在三个种之间为一致、包含、大部分重叠的关系；只有2个描述特征存在差异，一个是在吻长较上眼上缘距背鳍基部的长度特征上，短吻三线舌鳎和紫斑舌鳎为略长、等长或略短于的连续特征值，而褐斑三线舌鳎为明显大于；另一个差异是体表的花色差异，紫斑舌鳎体长一般小于200 mm，且具有明显的斑纹，短吻三线舌鳎体长一般大于200 mm，且随着体长增加，斑点逐渐淡化或者无斑，而不同体长的褐斑三线舌鳎在头后和身体前3/4均具有明显的零星褐色斑纹。COⅠ分子条形码结果显示，短吻三线舌鳎和紫斑舌鳎的遗传距离为0.000～0.002，为种内差异;褐斑三线舌与其他两种舌鳎之间的遗传距离为0.141～0.145，为种间差异。研究表明，短吻三线舌鳎和褐斑三线舌鳎是有效种，紫斑舌鳎是短吻三线舌鳎的次同物异名。本研究结果为鲽形目鱼类的正确分类提供了科学依据。

Ba.kground: Self-ca.e ta.ks or a.tivities of da.ly living (a.L)’s performa.ce a.e often disrupted a.ter a. older a.ult susta.ns a. injury or illness, which ca. be a.determining fa.tor for discha.ge pla.ement a.ter hospita.iza.ion, or it ca. determine the level of a.sista.ce required a.ter discha.ge from a.skilled nursing fa.ility (SNF).

The purpose of this study is to determine if a. individua.’s level of independence improved a.ter a.mission to a.skilled nursing fa.ility a.d procurement of reha.ilita.ion services.
