star density 中文意思是什麼

star density 解釋
恆星密度
  • star : n 1 星；【天文學】恆星 （opp planet）。2 星狀物，星（形勛）章。3 【印刷】星形號〈 〉。4 【占星術...
  • density : n. 1. 稠密；濃厚。2. 【物理學】濃度；密度；比重。3. 愚鈍，昏庸。
  1. What is left after an explosion is a dwarf star of extraordinary density.

    爆炸后所留下的是一個密度巨大的矮星。
  2. Our results show that with the up to date experimental data, 13c can not sufficiently burn, the neutron number density decrease, the timescale of neutron source become long and these come into conflict with model of thermal pulse agb star

    研究結果表明，在新實驗結果下， 』 3c不能充分燃燒，中子數密度降低，中子源持續的時標變長，這與熱脈沖agb星的現有模型出現矛盾。
  3. A star is formed when a cloud of gas collapses from the interstellar medium toward high density.

    一個氣體雲自星際物質中坍縮，密度達到很高時，即形成了一個恆星。
  4. Because of its great mass, both the core temperature and density are higher than that of a solar mass star. the nuclear reaction rate is also higher and it produces more energy per second. the star is of spectral type o, b or a

    由於質量更大，恆星核心的密度及溫度亦必然比小質量恆星高，所以熱核反應會以更快速度進行，產生出更多的熱能，恆星會更加光亮，這些恆星通常為o b或a型恆星。
  5. We also prove that the radius of a rotating spherically symmetric star, with given constant angular velocity and constant entropy, is uniformly bounded independent of the central density. this is different to the case of the non - rotating star

    非常有趣的是，當角速度和熵函數都是常數時，旋轉對稱星體的半徑關于中心密度是一致有界的，這與非旋轉星體是截然不同的。
  6. It says that the stars indeed rotate at different speed, but the density of the interstellar medium form a wave. at the wave front, where the density is higher, star formation is enhanced. that is why we find young stars along the spiral arms and old stars elsewhere

    這個理論認為雖然恆星會以不同速度移動，但星際物質的密度會產生波動，在密度最高的波陣面會催生出新的恆星，這解釋了為何通常在旋臂會找到新生恆星，而在其他地方只有古老恆星的原因。
  7. Toronto star : women with a high proportion of dense tissue in their breasts have a far greater risk of developing breast cancer than women with low - density tissue, a long - term canadian study has found

    多倫多星報：加拿大一項長期性研究項目顯示，乳房組織密度高的女性患乳腺癌的幾率遠遠高於組織密度小的女性。
  8. In a similar manner, earth is in the process of returning density or darkness that did not originate either in this creation, or from other star systems that have utilized earth as a storage facility for their darkness

    以類似方式，地球正在將緻密或黑暗歸還，這類緻密或黑暗並不在此創造物中起源，而是來自其它恆星系統，他們將地球作為自身黑暗的儲存容器。
