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。Among the evolution is the chemical evolution of the galaxy showing its exceeding importance. the recognize to the galaxy chemical evolution build up the basement of understanding the whole galaxy evolution. and it can restrict and constrain the evolution and ncleosyhthesis of the stellar
其中銀河系的化學演化在其中更是具有極其重要的地位，對銀河系化學演化的認識是理解整個銀河系演化的基礎，並對恆星演化與核合成理論提供約束。That is the following in essence. a sufficient mass of cold matter will necessarily collapse to a black hole, and stars with different mass will evolve into the white - dwarf - star, the neutron - star or the black - hole eventually because of the radiation of the burning core. the collapse of stars with sufficient mass leads to a black hole endowed with mass and charge and angular momentum, no other adjustable parameters : " a black hole has no hair.
第二章簡單介紹一下「黑洞無毛」理論形成，即足夠質量的冷物質能夠塌縮成黑洞，不同質量的恆星由於核燃燒輻射最終會演化成為白矮星、中子星或黑洞，以及黑洞的終態系統唯一地由質量、電荷和角動量確定，而無其它物理參數，此即為「黑洞無毛」理論。Within these tight knots of stars, observers in recent years have discovered bodies that are forbidden by the principles of ordinary stellar evolution ? but that are naturally explained as smashed - up stars
在這些緊密的恆星集團內，觀測者近年已發現通常的恆星演化理論所不容許存在的恆星，於是很自然將它們解釋成撞擊而形成的恆星。Such a figure caused controversy. the stellar evolution theory states that the oldest globular cluster might have existed for 15 billion years. how could a star be older than the universe
當時曾掀起一場爭論，因為從恆星演化理論得知，一些最老的球狀星團可能已有150億年的壽命，怎可能星體比宇宙更年老？The discovery of isolated black holes agrees with the stellar evolution theory that black hole can be formed naturally when a massive star collapses under its own gravitation. binary system is not a necessary for its formation
黑洞可以孤立地存在，暗示著黑洞並不一定需要存在於雙星系統，而可以透過孤立的大型恆星的重力塌縮而產生，這正是一直以來恆星演化理論所預期的結果。" for his theoretical studies of the physical processes of importance to the structure and evolution of the stars
