死亡率

Our study documents that smoking is a major risk factor for mortality in China.

我们的研究结果表明：在中国，吸烟是死亡率的主要风险因素。

Results In the control group, 68.6% motoneuron death of spinal cord occurred by 3 weeks following surgery, and the size of surviving motoneurons was significantly atrophy and NOS positive neurons increased. In the experimental group, the mortality was decreased by 35% as compared with that in the control group.

结果 对照组68.6%的神经元死亡，存活神经元胞体明显萎缩，同时表达NOS神经元增多；实验组的死亡率较对照组降低35%，存活神经元胞体无萎缩，表达NOS神经元未见增多。

Each kind of date age's muscovy duck may also infect the morbidity, epidemic disease propagation velocity is quick, one week may infect the entire group, the disease incidence rate and the mortality rate may reach as high as 80%.

In addition to the rising of natality and the increasing of migration, the falling of mortality is an another factor to quicken the population.

除了出生率的上升和移民人数的增加，死亡率的下降也是人口增长的一个因素。
