Using population synthesis method, the star formation history in globular clusters has been studied. No single star formation mode with a constant star formation rate (SER) and an invariable initial mass function (IMF) can fit the observations of globular clusters. There are at least two stages of star formation: a pollution stage and a starburst stag-e. In the pollution stage, either the IMF is very peculiar (only form massive stars), or its SFR is so small that the low-mass stars form only a little. A starburst:...

Using population synthesis method, the star formation history in globular clusters has been studied. No single star formation mode with a constant star formation rate (SER) and an invariable initial mass function (IMF) can fit the observations of globular clusters. There are at least two stages of star formation: a pollution stage and a starburst stag-e. In the pollution stage, either the IMF is very peculiar (only form massive stars), or its SFR is so small that the low-mass stars form only a little. A starburst: then follows to form most stars in the globular cluster. Within the framework of Fall and Riees'model, the collisions between warm clouds in the two phase medium may provide a suitable external cause to stimulate the starburst.

本文根据球状星团所特有的金属丰度特征,利用星族综合方法,探讨了球状星团诸恒星的形成史。研究表明,这些恒星不可能通过恒星形成率和初始质量函数均不随时间变化的单一恒星形成模式产生。原初云通过恒星演化而得到金属丰度污染的过程和多数恒星的形成过程必须分为两个不同的阶段。 球状星团得到金属丰度污染的过程中,若恒星形成具有通常的初始质量函数,则其恒星形成率必须较低,且初始质量函数不能太陡,从而使污染过程中只形成数量较少的低质量恒星,以保证单个球状星团内金属丰度的均匀性。另一种可能性是污染阶段有非常特殊的初始质量函数,只形成大质量的恒星,从而除提供适量污染外不留下任何痕迹。 多数恒星应是在原初云不同部位得到适当污染后通过局域的短暂的爆发性恒星形成(星暴过程)产生。本文进一步探讨了在Fan和Rees球状星团形成模型的框架下,两相介质中温云块相互碰撞造成星暴过程的可能性。

On the basis of the model that a neutron star accretes the comet clouds around it, we put forward that the soft gamma ray repeater GB790107 originates from the weak magnetic field (~108G) old neutron star. The accretion on the neutron star forms an optically thick radiation region, whose temperature distribution is determined by shock wave model proposed by Munt, and whose blackbody emission can fit the observational spectrum of GB790107 well. We find that the source distance is between 1.35 pc and 13.5 pc.

本文在中子星吸积彗星云模型的基础上,认为软重爆GB790107起源于弱磁化(B~10~8G)中子星,其阵雨式地吸积彗星云将在中子星表面形成一光厚辐射区,该辐射区的温度分布由激波模型确定.这一辐射区中的高温等离子体产生的黑体辐射将很好地拟合GB790107的观测能谱,且获得爆源距离为(1.35~13.5)pc.

Because of influence of cooling conditions, properties of casting powder and structure of mould as well as vibration way it is discovered that surface crack, corner crack and star form crack occur frequently in continuous cast slabs, consequently leading to reject-ed products after rolling, affecting production and quality. In connection with the actual con-ditions of AISC No. 1 slab caster it is found to be of great significance for reducing crack de-fects to se1ect proper casting powder, control and improve...

Because of influence of cooling conditions, properties of casting powder and structure of mould as well as vibration way it is discovered that surface crack, corner crack and star form crack occur frequently in continuous cast slabs, consequently leading to reject-ed products after rolling, affecting production and quality. In connection with the actual con-ditions of AISC No. 1 slab caster it is found to be of great significance for reducing crack de-fects to se1ect proper casting powder, control and improve secondary cooling system and withdrawal speed, to avoid steel embrittlement temperature range from 600 to 90℃ as well as reduce stress concentration.

连铸板坯在实际生产中由于受冷却条件、保护法性能、结晶器的结构以及振动方法等因素影响,常常产生表面裂纹、角部裂纹、星形裂纹等缺陷,造成轧后废,影响产量和质量。针对鞍钢1号板坯连铸机的实际情况,认为选择合适的保护渣,调整二冷水与改进拉速,避开钢在600~900℃脆化温度范围,力求铸坯厚度均匀,减少应力集中,对于减少裂纹缺陷是非常重要的。
