Urbanization significantly increases the risk of urban flooding. Therefore, quantitative study of urban rainfall-runoff processes can provide a scientific basis for urban planning and management. In t...
中国科学院地质与地球物理研究所王新等-JGR：利用ScS多次波研究日本海及其邻近区域地幔过渡带结构（图）
中国科学院地质与地球物理研究所 王新 ScS多次波 日本海 邻近区域 地幔 过渡带结构
2017/5/3
地幔过渡带是指地下410-km和660-km不连续面（间断面）之间的地幔部分，是联系上下地幔的纽带。俯冲的海洋岩石圈和地幔过渡带之间的相互作用是地球动力学研究的一个关键问题。通过对410-km和660-km间断面深度的探测，可以为了解地幔温压条件、物质组分、岩石圈深俯冲等地球深部动力学问题提供重要途径。西北太平洋俯冲带北起千岛群岛，中经日本伊豆-小笠原地区，南至马里亚纳群岛，是世界上最典型、最集中...

简要介绍了南海西南次海盆OBS 3D 地震探测台阵, 整理并详细分析了宽频带OBS的天然地震记录, 结果表明共记录了Ms 6.0~6.9 地震93 个, Ms 7.0 以上地震10 个, 数据质量较好, 特别是2011 年3 月11 日日本仙台以东海域发生的Ms 9.0 大地震. 对4 次Ms 7.0以上地震的ScS 波进行了各向异性反演, 结果表明西南次海盆的快S 波偏振方向N58°E 平行于已...
参数λ是SCS产流模型的一个重要参数,模型研究者将标准值λ=0.2作为模型的参数值。但模型参数没有考虑地貌类型对产流的影响,喀斯特地区不同地貌类型下地表坡度、土层厚度、地层岩性、基岩裂隙的发育程度等方面均存在很大差别,而这些因素都直接影响着流域的产流机制。在考虑地貌类型对喀斯特流域产流影响的基础上,通过率定不同地貌类型下的λ值对SCS模型进行改进。以GIS和RS技术作为获取流域地貌类型、土壤类型和...

摘要 以表面铺展法制备德国蚌镰精母细胞联会复合休（9C5）标本，经硝酸银染色后作电镜观察。结果表明，减数分裂S5。组型和有丝分裂染色体组型基本一致；在减数分裂前期，X染色体自身折叠形成典型的“发夹”状结构。电离辐射诱发SC、出现多种畸变，如倒位、重复、缺失、易位以及SC提前分离等。对X染色体自身拆叠形成的可能机制、SC缠绕交叉与染色体交换的关系以及SC畸变分析的潜在应用价值和遗传学意义作了讨论。
