Timing of hurricane emergency actions

Emergency actions to prepare for hurricanes often require more time than is available from official public warnings. This means that the preparedness official must decide not onlywhat to do butwhen to do it. The action decision system, described here, developed for use in the State of Florida, reformats the hurricane track forecast, a 72-h projection, prepared at the National Hurricane Center in Miami, to specify the probability of a strike at each of 12 vulnerable coastal communities, and then normalizes the value in terms of a composite of probabilities computed for historic hurricanes that struck the respective communities. The normalization, a ratio of the two probability values, current and historic, expressed as a percentage is defined as the level of risk. When this level reaches or exceeds 100% the risk level is defined as critical and the system recommends that emergency actions to prepare begin immediately.The system is founded upon individual hurricane climatologies and decision procedures that are tailored for use at each community. The action recommendations generated by the risk analyses with a 93% level of confidence relieve the preparedness official of the need to make meteorological decisions in timing evacuations and other critical measures, even when these must begin before official hurricane warnings are received.The work that provided the basis for this publication was supported by funding under a Cooperative Agreement with the Federal Emergency Management Agency.

中央广播电视发射塔环境电磁辐射测试研究

对发射７套电视节目和５套调频节目，发射总功率２４０ＫＷ的中央广播电视塔电磁辐射场强监测结果表明：（１）由于节目频率不同，发射机功率及发射天线形式、高度、增益不同，电磁波到达地面最大场强值的距离是不同的；在近距离内高层建筑各层所接收到的场强大小也是不同的。（２）电视与调频信号在近距离昼夜电平无明显变化。（３）电视塔周围２０００米内环境综合场强最大值为２８４～３２８μＷ／ｃｍ２，所有环境测量值均小于公众导出限值４０μＷ／ｃｍ２。     

氯气检测管的研制

经过条件优化试验，研制出氯气检测管。检测管显色长度与氯气浓度呈线性相关，对氯气标气7次测定的变异系数为13．8％，平均相对误差为5．2％，小于15％；一次测定最大相对误差为20％，小于25％，符合国家标准GB7230－87的要求。与化学法比较，2种方法测试结果无显著性差异。干扰物有溴和氯化氢气体以及高浓度二氧化氮。检测管寿命为1a。

长乐—南澳变质带显微构造和岩组特征及应力场分析

通过光学显微镜和高压电子显微镜对带内的变形石英进行显微构造超微构造观测和估算变形参数(σ_1-σ_3=85.0MPa,ε_s=10~(-9)～10~(-10)/S),认为该区变质岩形成于深层环境,是长期缓慢变形的结果。变形石英位错构造为变形阶段和恢复阶段的混合体,其变形机制为塑性形变。采用石英光轴干涉图法,在偏光显微镜下对水平定向薄片进行岩组测量,绘制成该区的石英光轴方位图,探讨其构造变形的演化历史。首次划分出S(或S+S)和B+S构造岩岩组类型及Ⅰ型、Ⅳ型和Ⅴ型石英定向类型。应力场随着构造变形的演化作逆时针旋转。山南北挤压应力场逐渐变为单向推挤的应力场,从而认为构造变形是多期次的叠加。
