neutron gas 中文意思是什麼
neutron gas
解釋
中子氣體-
On the bases of the galaxy evolution theory, we use the therotical chemical evolution model of three zone ( such as halo, thick disk and thin isk ) and multi - phase ( diffuse gas, molecular clouds, stars of both low and high mass, the remnants ). by comparing with the observational constraints, such assurface densities, age - metallicity relation, g - dwarf metallicity distribution in the solar neighbourhood and the correlation between [ a / fe ] and [ fe / h ], supernovae rates, infall rates. the rationality of the model is verified. based on the theory model, we calculate the abundance of neutron capture element
本文正是在銀河系化學演化的基礎上，利用銀河系的三成分（ threezone ） （即暈、厚盤和薄盤）多相（ multi - phase ） （氣體，分子云，大、小質量恆星以及剩餘物質）的化學演化的理論模型，通過與觀測約束（質量面密度、場星的年齡-金屬豐度關系、太陽附近g矮星金屬含量分佈函數、三成份的特徵量、元素的星系化學演化、超新星的爆炸率、內落速率等）的比較，來檢驗模型的合理性。 -

More important, details about the birth of the neutron star could be extracted from the gravitational signal even though the nascent object itself is tiny and swaddled in a blanket of fiery gas
更重要的是，雖然新生的中子星非常小，又包裹在熾熱的氣體里，但我們還是可以從重力訊號中，解讀出中子星誕生的一些細節。 -
Emphasis is placed on the industrial application of gamma scanning in tower operation and the neutron backscatter in the level detection of an industrial gas / liquid separator and a hydrogenation reactor
這些應用情況表明，利用射線檢測技術不僅可以準確診斷石油化工設備的故障，還可以用於裝置的運行狀況評價、操作優化、挖潛增效以及實現預測維修等多個方面。 -
Also shown are huge clouds of multimillion degree gas and bright point like sources due to neutron stars and black holes
同樣顯現在其中的是巨大的氣體雲團，溫度達幾百萬度，還有明亮的點源，這是由於中子星與黑洞造成的。
