angular momentum conservation造句

angular momentum conservation is based on the isotropy of space .
角动量守恒是以空间的各向同性为基础的。
as it contracts, the principle of angular momentum conservation forces it to rotate faster [ see box on opposite page ]
当它收缩时，角动量守恒的原理强迫它转得更快（见右页气体盘的诞生）。
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。
