- Example Sentences:
| 1. | It is very significant for ba stars to heavy - element nucleosfynthesis and galactic chemical evolution
钡星对于重元素核合成及星系化学演化的研究都有非常重要的意义。 | | 2. | The obvious overabundances of heavy - element are observed in ba stars . however , the luminosity of ba stars is too low to reach agb stage , and the nuclear 99tc have not observed in ba stars
钡星的重元素是过丰的，但其光度太低，认为还未演化到agb阶段，而且并没有观测到~ ( 99 ) tc核素。 | | 3. | In general , ba stars belong to binary system , and their heavy - element overabundances are due to the accreting material from the companions ( the former tp - agb stars and the present white dwarfs ) . carrying out a series of monte - carlo simulations , the changes of orbital elements of binaries are recalculated for wind accretion scenario of the total angular momentum conservation
研究表明，钡星应该属于双星系统，其重元素超丰来自双星吸积，它的伴星已经经历了s -过程核合成，而且由在以前发生的同其伴星(以前是agb星，现已演化为白矮星)的质量传输过程中，从伴星那里获得了富含重元素的物质，这样造成了钡星的重元素超丰。 | | 4. | Our results show that , during the evolution of a binary system , the system widens as it loses mass , and the orbital period increase , while orbital eccentricity remains nearly constant , which can explain the distribution regulation of orbital elements of normal g - k giant and barium stars and the distribution character of the heavy - element abundances of barium stars
计算结果表明，随着星风吸积过程的进行，在星风质量损失阶段系统轨道半长轴将增大，导致轨道周期增大，而偏心率变化不大，由此可以解释普通红巨星双星系统和钡星系统的轨道根数的分布规律和变化情况以及钡星重元素丰度分布特征。 |
