| 1. | In high - redshift galaxies , however , the rate of star formation is 10 times as great 但是,在高红移的星系中,恒星形成率是这个数目的10倍之多。 |
| 2. | Hypocotyls were excised from 7 , 11 and 30 days old aseptic seedling to transform under the same condition 分别研究了胡萝卜不同苗龄( 7d 、 lld 、 30d )的抗性愈伤形成率。 |
| 3. | The deep observations have also traced the waxing and waning of star formation in the universe at large over cosmic time 回溯宇宙年代的深度观测,同时也追踪了整个宇宙恒星形成率的变化。 |
| 4. | - 10 - ivm oocytes were fertilized in vitro , and the process of fertilization , early cleavage , and blastocyst formation were recorded 通过体外受精观察比较各组体外成熟卵细胞的受精率、卵裂率和囊胚形成率: 6 |
| 5. | When the universe was relatively young ? one billion years old ? the star formation rate was already high , about a third of its peak value 宇宙还很年轻时( 10亿年左右) ,恒星形成率已经非常高了,大约是全盛时期的1 / 3 。 |
| 6. | In our own milky way , which is quite typical of nearby , massive spiral galaxies , the number of observed high - mass stars indicates that stars are forming at a rate of a few solar masses a year 银河系可说是我们周遭大质量螺旋星系的典型,根据观测到的大质量恒星数目判断,银河系的恒星形成率为每年数个太阳质量。 |
| 7. | Because high - mass stars live for only a few tens of millions of years ? a short time by galactic standards ? their number closely tracks variations in the galaxy ' s overall star formation rate 由于大质量恒星只能存活数千万年,这在星系的标准看来算是很短的时间,因此它们的数量很适合用来追踪星系中恒星形成率的整体变化。 |
| 8. | Based on the work of some pioneers in this area , the paper begins with a brief theoretical summary of the irregular financial activities and their relevance in china . then , the author provides a detailed analysis as to how this " one - and - a - half market has come to be 处在经济转轨过程中的中国,由于政府执行金融抑制战略,非正规金融活动大量存在,并且直接促进了中国经济结构的有效调整,对于经济效率、资本形成率的提高、体制改革具有很强的导向作用。 |
| 9. | 3 . the choosing of optimum evaluating methods of immunobiologic activity : if we disposed sheep blood red cells with neuraminic acid enzyme , the e rosettes forming ratio remarkbly increased ; we improved the conventional method of brdu - elisa assay on lymphocyte proliferation induced by cona . the results showed that lymphocyte proliferation induced by pha was better than by cona . 4 3 、 gpif免疫生物活性评价方法的优化对gpife玫瑰花环实验在不影响srbc活性的基础上用神经氨酸酶处理,经此法处理后e玫瑰花环形成率明显提高;对传统的cona诱导的人外周血淋巴细胞增殖brdu - elisa实验,进行了方法学改进。 |
| 10. | The emerging consensus is that the early universe was dominated by a small number of giant galaxies containing colossal black holes and prodigious bursts of star formation , whereas the present universe has a more dispersed nature ? the creation of stars and the accretion of material into black holes are now occurring in a large number of medium - size and small galaxies 目前逐渐形成的共识是,早期宇宙是由数量稀少、但含有巨大黑洞,且恒星形成率超高的巨型星系所主宰,今日的宇宙则具有较零散的特性恒星的诞生与黑洞吸积物质的作用,发生在庞大数量的中、小型星系内。 |
