查询词典 momentum

For the first time we parametrize such a flow with two physical constants, namely the specific angular momentum accreted by the black hole j and the energy quantity K.

We set up the angular momentum conservation model of wind accretion of Ba stars, and then derive the change equations of the orbital elements. Finally, combining the heavy element nucleosynthesis of AGB stars, we creatively calculate the heavy-element overabundances of barium stars in a self-consistent manner adopting accreting and mixing on successive occasions.

我们建立了Ba星形成的星风吸积的角动量守恒模型，推导出其轨道根数的变化方程，并结合AGB星的重元素核合成，通过逐次脉冲吸积与混合，自洽地计算出Ba星的重元素超丰。

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。
