物理设计的主要研究内容包括：分析目前国内国际空间天气预报的发展现状及开展空间天气预报的必要性和重要性；分类讨论了灾害性空间天气的种类、影响及目前国际上的预报方法：分析了空间天气太阳扰动源及扰动源爆发的先兆现象或者伴生现象；讨论了太阳短波辐射线谱和连续谱辐射强度的计算方法：推导了利用望远镜多波段的观测结果反演日冕等离子体温度、发射量等参数的物理方法：论证了开展空间天气经验预报和发展数值预报有效的成像谱段。 - It is found that : ( 1 ) for linear slope , redistribution of incoming energy flux in modenumber space depends on both the modenumber of incident waves and the ratio of the slope of incident wave ray to slope of topography ; both the transmitted and reflected energy flux ( only for supercritical linear slope ) focus near one or two modenumbers ; for supercritical linear slope , the energy flux scattering to higher modenumbers becomes larger and the energy flux to lower modenumbers becomes smaller as the slope of incident wave ray comes near to slope of topography ; ( 2 ) for convex slope , energy flux is redistributed in wide - range modenumbers and also show peaks on lower - modenubers and higher - modenumbers ; ( 3 ) for concave slope , energy flux is also redistributed in wide - range modenumbers , but does not show peaks on higher - modenumbers as supercritical linear slope and convex slope do ; ( 4 ) the total energy flux scattering to higher modenumbers is approximately equal to the total energy flux to lower modenumbers for internal waves propagating over both convex slope and concave slope , which means the concave slope is the same efficient to convex slope in scattering energy flux to higher modenumbers ; ( 5 ) for convex slope , the wave ray reflected from near - critical topography can extend to deep ocean and shallow shelf , while for concave slope , the wave ray reflected from near - critical topography can only extend to limited distance , then meet the topography and be reflected again ; generally the shear of the internal waves reflected twice from concave slope is not enhanced while the enhanced shear does also appear before second reflection takes place , the enhanced shear can bring about intense mixing , so internal waves reflected from concave slope can also produce marked mixing near critical slope
3 、内波在凹地形上传播时，能通量在模态上的分布范围也比较宽，但与凸地形和超临界线性斜坡地形相比，能通量在高模态上的分布没有明显的峰值。 4 、从总的能通量来讲，内波在凸地形和凹地形上传播时，向高模态散射的能通量与向低模态散射的能通若十地形下内波传播及内潮生成问题的理论解量近似相等，这意味着二者在向高模态散射能通量方面具有同等效率。 5 、凸地形上临界点附近的反射，反射波的波射线能够延伸到深海和陆架，凹地形上临界点附近的反射，反射波的波射线很快遇到地形发生二次反射，一般来讲二次反射后回到深海的波动其速度剪切并不很强，但是在进行二次反射之前的区域，速度剪切仍然很强，因而内波在凹地形上的反射依然能够在地形附近区域，产生强的速度剪切区，诱发混合。 - According to state - of - the - art of evaporation duct propagation research , and to meet the demands on the prediction techniques of evaporation duct environment and the assessment of radar performance under evaporation duct environment , this dissertation gives a thorough research in depth on the subject described above . the researches include the prediction theory of evaporation duct and its applications , the theory of ray tracing based on which the prediction of radio wave rays are conducted and its application to the predicting of radar range performance under a given evaporation duct , and the characteristics of tropospheric ducts over china
