Based on a series of analysis for the relevant data during the period of 1950~1989, the relationship between the ozone layer variation/ solar activity and the periodically prevalent features of two kinds of human infectious diseases in China, the epidemic cerebrospinal meningitis and human plagueepisodes, is presented and analyzed for the first time in this paper.

通过对1950~1989年间一系列有关资料进行分析，首次研究和报道了臭氧层变化、太阳活动与流行性脑脊髓膜炎及鼠疫传染病发病率流行周期特征之间的关系。结果表明，从较长时段看，臭氧层变化、太阳活动与ECM、HP年发病率间存在着较为密切的相关关系；从较短时段看，发病率的季节变化与某些气象因子的变化有一定的关系。此外，本文还提出了一个解释这两类疾病周期流行机制的简单模型

The accuracy of present numerical model is verified by the simulation of a rectangular harbor with constant water depth. For Taipei Harbor calculations, three incident wave directions, namely, WNW, N and NNE, together with constant water depth of 10m are considered.

接著考虑台北港第三期配置，使用三个波波浪入射方向与代表性水深(10m)，配合港区码头位置的选定，计算入射波浪周期与波高放大因子的关系，同时由共振周期计算港域波浪场的分布情形，藉以了解台北港第三期规划案港池振荡的特性。

It is shown also that the propagation of the soliton with an order of amplitude of picosecond width is hardly to produce stimulated Raman amplification, but the soliton with narrower width (generally, smaller than few picoseconds) is better synchronous with Raman wave, and the stimulated Raman amplification can be produced easily.
