infallible

Our test with mock samples shows furthermore that one can discriminate among such models already with currently available observational samples ( if the measurement error of the redshift is negligible ) which have a typical error of 80kms - 1 . the error will be reduced by a factor of 2 if the samples are increased four times . we also show that an errroneous assumption about the geometry of the universe and different infall models only slightly change the results 結果表明: ( 1 )若用現有的觀測樣本(特征誤差為80kms ~ ( - 1 ) )我們已經可以限制星系形成模型,而如果樣本容量增長到4倍,誤差將減半; ( 2 )錯誤地假設宇宙幾何和星系平均內落對結果只有微弱的影響。

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、小質量恒星以及剩余物質)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矮星金屬含量分布函數、三成份的特征量、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。

Finally , due to the rapid rotation of the neutron star , or the evolution of the companion , the infall of matter stops , the x - ray emission declines , and the neutron star emerges as a radio - emitting millisecond pulsar 最后,由于中子星疾速的自轉,或是伴星自身的演化,物質的流入停止, x射線輻射減弱,這顆中子星就呈現出了毫秒脈沖星的面目。

4 . the temperature of infall cooling water is less than 30 , the velocity of cooling water flow should be over 4l min for capacitor below 1000kvar and it should be over 6l min for capacitor over 1000 kvar 4 .冷卻水的進水溫度不超過30 ,冷卻水的流速對1000kvar及以下的電容器不低于4l min ,對1000kvar以上的電容器不低于6l min 。

This result was very surprising ; it cast doubt not just on the gas - infall model but on the entire theory of bar waves 這結果令人非常驚訝,因為它不只詰難這個氣體墜入模型,也質疑整個棒波理論。
