摘要文章论述了华东火山岩型铀矿找矿值得重视的地质问题：①铀成矿既可形成于浅源浅成低温条件，也可形成于深源深成高温或深源浅成中低温条件，在强调深源时，不是简单地认为是幔源就可以了，还必须强调壳幔作用的地质过程；②打破人为的&类型&划分，加强&铀成矿系统&的研究，更好地指导找矿；③研究基性脉体与铀成矿问题应注意构造、岩石矿物成分、成因、蚀变与成矿3大问题，注意寻找泥岩化作用强烈的破碎辉绿岩脉中的富铀矿；④火山盆地基底对铀成矿的作用主要是提供铀源，将基底对铀成矿的影响从感性认识推向理性认识，有效地指导找矿；⑤红盆与铀成矿关系可以从构造、古气候及时间分析研究中得出结论，它不仅仅是一个理论问题，而且有助于铀成矿预测；⑥隐爆角砾岩筒是铀成矿、成富矿的重要储矿构造，是华东火山岩型铀矿找矿的新领域。

Seven thirdorder seismic sequences can be recognized from bottom to top in the Paleogene in the Wushi sag, which consist of a depositional sequence from transgression to regression as a whole and correspond to different stages of structural evolution. Sequences developed in different stages of structural evolution are different in filling sequence and distribution of sedimentary system. Multiphase structural evolutions result in development of source rocks and reservoir and cap rocks in various parts of the sag. The sequence 2-4 deposited in strong chasmic stage have the best source rocks and sealing conditions as well as various favorable reservoirs, thus are the most favorable targets for obtaining discoveries in this sag.

结果认为：乌石凹陷古近系从下至上可以划分为7个三级地震层序，整体上为一个水进到水退的序列，分别对应不同的构造演化阶段；不同构造演化阶段发育的层序具有不同的充填序列和沉积体系分布；构造演化的多期性使得该凹陷多个部位都有烃源岩和储、盖层发育；其中以强烈裂陷阶段沉积的层序2-层序4中发育的烃源岩和盖层条件为最好且发育多种有利储集体，是该凹陷寻找油气藏的最有利层段。

The biomarkers such as the n-Alkanes, the isoprenoids, the terpane, and cholestane were detected through GC-MS analysis. Based on the study of the biomarkers, the biological evolution during Permian and Triassic can be divided as three stages, namely, the mixing source stage of low biota such as thallose and advanced plant in late Permian (below bed 63), the stage of low biota such as thallose in the boundary transitional layer (bed 63-69) and the mixing source stage of advanced plant and low biota such as thallose in early Triassic (above bed 69). What's more, the second stage near the boundary transitional layer can be subdivided into 4 stages. The stages of biota evolution is close related with sedimentary environment changing and the boundary transitional layer.

Comparing the SXR and microwave data with the optical data leads to the following scenario: the corona has been already heated to some extent before flare onset, and in the first two minutes of the impulsive phase, heat conduction was the main source or, at least, a competitive source, for chromospheric heating.

把软X射线和微波资料与光学资料比较研究，我们得到如下图象：在耀斑触发前，日冕已经加热到一定程度；在脉冲相的前两分钟里，热传导是色球加热的主要的或至少是极富竞争力的机制。

On the other hand, through the discussion on coronal density of flares, we found that the column mass density at the top of chromospheric flare model can not be represented the total mass above the chromosphere and the coronal density can be estimated from presure balance based on semiempirical model. Through estimations, the results show that the total mass above the chromosphere is about the same as the mass between the top of chromosphere and electron source, which so give an evidence that the source of electrons is situated at the top of flare loop.

另一方面，通过对日冕物质密度的讨论发现，半经验模型中色球顶部柱数密度不能用来代表耀斑环在日冕内的总物质，日冕物质密度可用日冕气压与半经验模型中色球顶部压力近似相等来进行估计，进而发现耀斑环在日冕内的总物质与前面估计的色球顶部到非热电子源之间的总物质近似相等，结果趋向于支持非热电子源位于环的顶部。

By comparison between SMM HXRBS observation and ground observation of Hα and CaIIK lines, especially through the combined study between SMM HXRBS observation and chromospheric flare models, the results show that: in the initial stage of impulsive phase, there is a correlative relation betweem Hα line intensity and hard X-ray emission; different spike in hard X-ray flux curve represents the burst at different location; the energy taken by non-thermal electron beam is larger than the radiative loss in chromosphere; for the flare studied here, the chromospheric evapporation is explosive; if the chromosphere is in balance between electron beam bombardment and radiative loss, the column mass density at the top of chromospheric flare model can not be taken as measure from the source of electrons and then the total material between the source of electrons and the top of chromosphere can be estimated.

通过一个具体耀斑的SMM HXRBS观测结果与同时基于地面得到的Hα和CaⅡK可见光谱观测结果对比，特别是将硬x谱观测结果与色球半经验模型联立研究，结果显示出：在脉冲相上升段，硬x发射与Hα辐射之间存在对应关系；硬x线光变曲线中不同脉冲爆发分量不太可能起源于同一位置；硬x辐射所反映的高能非热电子总携带能量大于色球总辐射损失；对所研究的耀斑而言，其色球蒸发过程是爆发性的；在详细比较了非热电子色球总沉积和色球辐射损失的基础上，指出半经验模型中色球顶部柱数密度不能看成是从非热电子源度量的，从而估计了色球顶部到非热电子源之间的总物质。
