软X射线太阳耀斑的典型脉冲阶段发展是从利用太阳峰年使命任务航天器上的弯晶光谱仪和硬X射线爆发光谱仪对大量耀斑的观测中得出的。在存在高速等离子体上升流（速度高达400 km s/sup-1/，温度约为10/sup 7/ K，湍流质量运动约为100 km s/sup-1/）的情况下，软X射线中脉冲相位的指示器。这也是耀斑期间日冕热等离子体的质量和能量增加的时期。
The typical impulsive-phase development of a soft X-ray solar flare is derived from observations of a large set of flares with the Bent Crystal Spectrometer and the Hard X-Ray Burst Spectrometere on the Solar Maximum Mission spacecraft. An indicator of the impulsive phase in soft X-rays in the presence of high-speed plasma upflows with velocities up to 400 km s/sup -1/, temperatures of approx.10/sup 7/ K, and turbulent mass motions of approx.100 km s/sup -1/. This is also a period of increase in the mass and energy of the coronal thermal plasma during a flare.
