The death of the speleologist is due to the infall of the cave . 这位洞穴学家之死是由于地洞的塌陷。

The infall of the pirates caused the villagers to live a miserable life . 海盗的入侵导致了村民的悲惨生活。

Collapsing interstellar cloud reverses its gravitational infall and expands outward into the relatively quiescent interstellar environment . 坍缩的星际云克服向内的引力而向外膨胀到较宁静的星际环境中去。

Nonlinear infall mode 非线性下落模型

This result was very surprising ; it cast doubt not just on the gas - infall model but on the entire theory of bar waves 这结果令人非常惊讶，因为它不只诘难这个气体坠入模型，也质疑整个棒波理论。

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 .冷却水的进水温度不超过30 ，冷却水的流速对1000kvar及以下的电容器不低于4l min ，对1000kvar以上的电容器不低于6l min 。

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转，或是伴星自身的演化，物质的流入停止， x射线辐射减弱，这颗中子星就呈现出了毫秒脉冲星的面目。

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 本文正是在银河系化学演化的基础上，利用银河系的三成分( threezone ) (即晕、厚盘和薄盘)多相( multi - phase ) (气体，分子云，大、小质量恒星以及剩余物质)的化学演化的理论模型，通过与观测约束(质量面密度、场星的年龄-金属丰度关系、太阳附近g矮星金属含量分布函数、三成份的特征量、元素的星系化学演化、超新星的爆炸率、内落速率等)的比较，来检验模型的合理性。

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 结果表明： ( 1 )若用现有的观测样本(特征误差为80kms ~ ( - 1 ) )我们已经可以限制星系形成模型，而如果样本容量增长到4倍，误差将减半； ( 2 )错误地假设宇宙几何和星系平均内落对结果只有微弱的影响。
