T The mild-slope equation is familiar to coastal engineers as it can effectively describe wave propagation in nearshore regions. However, its computational method in Cartesian coontinates often renders the model inaccurate in areas with ir-regular shorelines, such as estuaries and harbors. Based on the hyperbolic mild-slope equation in Cartesian coordinates,the numerical model in orthogonal curvilinear coordinates is developed. The transformed model is discretized by the finite difference method and solvef by the ADI method with space-staggered grids. The numerical predictions in curvilinear co-ordinates show good agreement with the data obtained in three typical physical experiments, which demonstrates that the present model can be used to simulate wave propagation, for normal incidence and oblique incidence, in domains with complicaed topography and boundary conditions.

冬半年（１０－４）月旬平均温度的预报是中央气象台中期天气预报的重要内容之一。气温的高低，不仅影响人们的生活，而且也影响到工农业生产的安排，尤其是春季的倒春寒和秋季寒露风天气，对早稻的播种育身和晚稻所花影响很大。因此，冬半年气温预报是大家极为关注的一个总理２。一般制作温度预报时，直接使用常规气象场的格点值呈各种组合作为预报因子。该文将常规气象场进行车贝雪夫展开，以此来更好地表征各场的主要特征，并浓缩
CH4是一种重要的温室气体,在空气中的含量仅次于CO2。化合物之间的相关性在化合物的浓度测量和估算等方面都有重要的意义。通过分辨率为1cm-1的长开放光路傅里叶变换红外光谱仪测量采样路径内的北京西四环高速公路附近空气CH4和CO透过率光谱,进行非线性最小二乘光谱拟合,计算出待测组分浓度。北京秋季空气CH4浓度变化趋势几乎一样。白天的浓度变化趋势表明城市中人为活动对CH4的排放影响极大,尤其是机动车
