查询词典 birth rate

Aldrin at concentrations higher than 40 μg/L decreased life expectancy at birth of F1 generation of the cladoceran, that at 20 μg/L and 80-640 μg/L decreased net reproduction rate, that at 320 and 640 μg/L shortened generation time, and that at all the concentrations decreased intrinsic rate of population increase. Aldrin at 160-640 μg/L shortened life expectancy at birth and generation time of F2 generation of the cladoceran, that at 160 and 640 μg/L decreased net reproduction rate, but that at all the concentrations except for 40 and 320 μg/L increased intrinsic rate of population increase.

浓度高于40μg/L的艾氏剂使多刺裸腹溞F1代的生命期望显著缩短，20μg/L和80~640μg/L的艾试剂使F1代的净生殖率显著降低，320μg/L和640μg/L的艾氏剂使F1代的世代时间显著缩短，所有浓度的艾试剂均使F1代的种群内禀增长率显著降低。160~640μg/L的艾氏剂使多刺裸腹溞F2代的生命期望和世代时间显著缩短，160μg/L和640μg/L的艾氏剂使F2代的净生殖率显著降低；除40和320μg/L外，所有浓度的艾试剂均显著提高了F2代的种群内禀增长率。

The incidence of asphyxia was also related with gender, polyembryony, birth weight, prematurity babies and aids to delivery from voginal. Conclusions The incidence of perinatal asphyxia is related with the gender, polyembryony, birth weight and gestation age as well as seasons.

Our main result is for any immigration-emigration birth and death matrix random environment, q, with birth rateless than death rate, there are a unique q-process in random environment P9*(0;t and a bi-immigration birth and death process in random environment with random transition matrix P(9*{Q);t such that P9*(0;t is ergodic and X* is a strictly stationary process.

在这一部分，我们将经典的生灭过程理论推广到了随机环境下，证明了对任意给定随机环境移入-移出-生灭密度矩阵q，当生率小于死率时，存在一个唯一的随机环境下的q过程—θ~*(0；t和随机环境下的移入-移出-生灭过程，使得严平稳，遍历，其随机转移阵为？
