- Chandra observations of the Centaurus A galaxy, where the star formation rate is extremely high, suggest that a massive AGN outburst occurred about 10 million years ago. 根据钱卓望远镜的观测，在半人马座A星系有著非常快速的恒星生成率，这表示在1000万年前曾经有颗超大质量AGN爆发过。
- Furthermore, a more thorough study of the light emitted by galaxies of different ages has shown that the star formation rate has not declined as steeply as once believed. 另外，针对不同年龄的星系所发出的光做详细研究，也显示出，恒星的形成速率并不像从前所想像的降低得那麽快。
- So it is naturally speculated that the LGRBs should follow the star formation rate (SFR), but the recent calculation indicated that the LGRB did not exactly trace the SFR. 因此人们很自然地推测长暴和恒星形成率直接成比例，但是最近数据分析表明这并不能很好地拟合观测。
- When Cowie and Lilly calculated the star formation rates in all the galaxies they observed, they came to the remarkable conclusion that the universe underwent a veritable baby boom at a redshift of about one. 当柯威与黎利针对他们观测到的所有星系，计算其恒星形成率时，他们得到了一个重要的结论：宇宙在红移值约为1时，正经历一股不折不扣的婴儿潮。
- star formation rate 恒星形成率
- And this is what kills star formation. 这就是为什么它会阻止星体形成。
- The booming black hole also stifles star formation. 黑洞是一种体积极小、质量极大的天体，其强大的引力，使得在它周围的区域里连光都无法逃逸。
- In heftier galaxies such as the Milky Way, star formation occurs at a more constant rate. 在比较大的星系中，如银河系，星球形成的速率较固定。
- The brightest area is a region of very active star formation. 最亮区是一个地区非常活跃的恒星形成。
- This is triggering a second stage of new star formation. 由此触发了第二阶段新恒星的形成。
- These waves compress existing gas and cause star formation. 这些波压缩现有的气体而引起恒星的形成。
- The Trifid Nebula itself represents the final phase of star formation. 三叶星云本身代表着恒星形成的最后阶段。
- KP formation rate was assoc iated with the initial concentration of KPE. 酮洛芬的形成速率与酮洛芬异丙酯初始浓度的大小有关 ,在低浓度时随酮洛芬异丙酯初始浓度增大而增加。
- Because they are rearranging the interstellar matter that is the raw material for further star formation, they may affect the rate of star formation in a galaxy. 星群爆发意味着重组星际物质，而这些星际物质恰恰是新星形成的原料，因此，星群爆发可能影响星系中新星形成的速度。
- The protostellar phase is an early stage in the process of star formation. 这不是核反应造成的，只是重力能量转换成的热动能。
- Yet the classical picture of star formation does not quite work either. 但是，典型的恒星形成图像对此并不完全适用。
- Results: The blastocyst formation rate and hatching rate cultured in hydrosalpinx fluid were decreased more ... 结论输卵管积水能显著影响胚胎的早期发育潜能。
- Micellar surfactant solutions were found to increase gas hydrate formation rate and storage capacity. 实验研究表明,表面活性剂胶束溶液可加快水合物的形成和提高水合物的储气质量。
- Embryos development was deserved after culture ever day,the blastocyst formation rate and hatching rate were accounted. 结果输卵管积水组的胚胎成囊率和囊胚孵出率低于无积水组,并呈剂量依赖性。
- Result:The hypothermia treatment can carry on smoothly,the complication formation rate is low. 结果:亚低温治疗能顺利进行,并发症的发生率低。
