| 1 | Equipartition and retrieval of Green's function显示文摘Physical and mathematical arguments are presented for equipartition as the statistical state achieved by a random field,independent of its sources,in the limit of enough scattering.The arguments are simplest for the case of thermally excited fields,but are shown to apply also,with caveats,in non-equilibrium acoustics and seismology.Practical implications are discussed. | Richard L.Weaver | 2010 | Earthquake Science2010，23，5： | 1 |
| 2 | On the generation and decay of the long-period coda energy of large earthquakes显示文摘Seismic coda wave is the tail portion of the earthquake record after main arrivals.Studies on the coda usually focus on high-frequency data within several hours after regional events and attribute them to the scattering effect of the heterogeneities inside the earth.Here,we use records of seven large earthquakes at globally distributed seismic stations to examine the decay of long-period(100 s to 300 s)coda in the time window of 10,000 s to 140,000 s after the origin time and fit it with a statistical model.The geometric spreading effect in the estimated initial energy and a locationindependent equivalent attenuation coefficient indicate that the long-period coda energy is less affected by the heterogeneity-induced scattering effect than that of shorterperiod coda.The coda energy can reach the earth’s inner core and can be explained by a 1D earth model,making it more effective for constraining the global attenuation model.It also has the potential to determine the magnitudes of large earthquakes and to explore the interior of planetary bodies. | Xinyu Jiang Xiaodong Song Han H.Xia Richard L.Weaver | 2021 | Earthquake Science2021，34，2： | 1 |

| 4 | 波多黎各西南部卡塔赫纳泻湖和罗霍角野生动物保护区的次生林演替和造林活动显示文摘次生林演替和造林对波多黎各西南部美国鱼类和野生动物局的罗霍角(Cabo Rojo)野生动物保护区(总部和盐沼区)及卡塔赫纳泻湖(Laguna Cartagena)保护区(泻湖和碗形潭)的恢复有很大作用。过去25年,在44hm^2土地上种植了约80个物种,其中主要是原生种,其目的是努力减轻地表火的威胁和恢复野生动物生境。2007年对泻湖区9年造林的调查显示,16个原生种的生长速度令人满意。单株树木地表处通常长出多个茎干。在整个109hm^2的碗形潭区,对次生林的取样显示有141个原生树种,或波多黎各原生树木区系的25%,还有20个外来种。有5个树种约占总胸高断面积的58%,有7个种是岛屿特有种。1998~2003年间,在碗形潭区内较低的30hm^2面积上,树木数量和胸高断面积,还有树高和胸径(距地面1.4m高处的直径)都增加了。在此区域内,大部分面积受到1996年火和放牧的影响,外来树种占物种总量的25%。遍及热带的干燥森林是一种濒危生境,它的恢复(即在生物量、结构和物种组成方面的恢复)在碗形潭会超过500年。但未来的森林有可能会保留一些外来种。 | Peter L.Weaver Joseph J.Schwagerl 王胜(译) | 2008 | AMBIO-人类环境杂志2008，37，7： | 0 |
