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。

Five papers are included in the part, which entitled as semiempirical models of the impulsive phase of the chromospheric flare, a study of the energy deposits in flaring atmosphere with semiempirical models of flares, spectral line asymmetry of solar flare, combined study between SMM HXRBS observation and semiempirical models, and continuum emission of white-light flare.

论文的上篇由5篇文章组成，形成了研究耀斑半经验模型的一个系列，其内容除了构造半经验模型外，着重在半经验模型基础上作扩展性研究，包括探讨耀斑的能量过程，计算谱线轮廓的不对称性，讨论白光耀斑连续发射的大气特征，以及寻求高能观测结果与半经验模型的联系等。

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。

The detailed time-match semiempirical models represnting the chromospheric state during the impulsive phase of the 2B flare on Fab. 3 1983 are proposed by making the non-LTE calculstions on hydrogen and ionized calcium. The physical pictures of total evolutionary pattern of the impulsivs phase of the flare are improved either quantitatively or qualitatively in comparison with the former work we did.
