流域非点源污染的量化识别方法及其在于桥水库流域的应用

本文介绍了量化识别非点源污染发生的时空规律的方法及其应用。通过对该方法最终所获取的各因子图和污染物发生模数图进行分析,可以识别出各因子的空间分布规律及其贡献、非点源污染物发生的时间特征和空间差异以及严重发生区等等。本文还尝试将此方法运用于于桥水库流域,研究结果表明:该流域非点源污染的发生时间几乎拿部在七、八两个月;流域地貌和植被是制约非点源污染空间差异的两个关键因素,调控植被覆盖的空间分布是非点源污染管理的重要途径;流域内长城沿线的狭长地带是总固体(泥沙)发生的严重区域,流域西部中央区是氮发生的重点区。

Salt tectonics and tear faulting in the central part of the Zagros Fold-Thrust Belt,Iran

The central part of the Zagros Fold-Thrust Belt is characterized by a series of right-lateral and left-lateral transverse tear fault systems, some of them being ornamented by salt diapirs of the Late Precambrian–Early Cambrian Hormuz evaporitic series. Many deep-seated extensional faults, mainly along N–S and few along NW–SE and NE–SW, were formed or reactivated during the Late Precambrian–Early Cambrian and generated horsts and grabens. The extensional faults controlled deposition, distribution and thickness of the Hormuz series. Salt walls and diapirs initiated by the Early Paleozoic especially along the extensional faults. Long-term halokinesis gave rise to thin sedimentary cover above the salt diapirs and aggregated considerable volume of salt into the salt stocks. They created weak zones in the sedimentary cover, located approximately above the former and inactive deep-seated extensional faults. The N–S to NNE–SSW direction of tectonic shortening during the Neogene Zagros folding was sub-parallel with the strikes of the salt walls and rows of diapirs. Variations in thickness of the Hormuz series prepared differences in the basal friction on both sides of the Precambrian–Cambrian extensional faults, which facilitated the Zagros deformation front to advance faster wherever the salt layer was thicker. Consequently, a series of tear fault systems developed along the rows of salt diapirs approximately above the Precambrian–Cambrian extensional faults. Therefore, the present surface expressions of the tear fault systems developed within the sedimentary cover during the Zagros orogeny. Although the direction of the Zagros shortening could also potentially reactivate the basement faults as strike-slip structures, subsurface data and majority of the moderate-large earthquakes do not support basement involvement. This suggests that the tear fault systems are detached on top of the Hormuz series from the deep-seated Precambrian–Cambrian extensional faults in the basement.

修改MICAPS系统配置参数提高气象资料时效性

通过在局域网络中建立专用MICAPS人机交互处理系统服务器,修改其余微机MICAPS系统配置参数就能直接访问该服务器处理好的资料,提高了现有气象业务系统利用卫星网提供的气象数据的效性,同时使全局能运行Windows3.x操作系统的386微机都能使用M1CAPS系统,大大方便了用户,提高了预报工作效率,最大限度地利用现有的计算机资料.     

基于文件系统的客户/服务器的应用

本文结合客户／服务器模型,提出网络应用的通用模型是客户／服务器模型的观点;同时对基于文件系统的客户／服务器的应用所采用的网络协议进行了简单的阐述,表明有针对性地选择多种网络协议可以大大地方便应用开发。     

基于5G RCS UP1.0标准的天气消息支撑系统设计与实现

气象短信服务在气象部门已有十多年的历史并有较广的覆盖面，由于一直以来受运营商传统短信网关的技术能力限制，仅能提供70个字的文字服务。2020年随着三大运营商联合发布《5G消息（5GMC）白皮书》,推出了RCS（Rich Communication Suite, 富媒体通信）,该技术具备融合语音、消息、视频、社区网络等多种功能，为传统短信业务的全面升级提供了技术支撑。本文立足现阶段手机终端普遍支持的RCS UP1.0标准，研究建立“5G天气罗盘制作发布支撑系统”提供以图片、视频等形式的服务内容将天气消息多媒体化，并通过Chatbot的NFS（Network File System）回落技术实现非5G用户以彩信回落的方式接收5G消息，对传统气象短信进行迭代升级，取得了较好的运行效果。
