- Van Doorn (1991) explained how quasi stationary distributions for an absorbing birth death process could be determined from the transition rates of the process. 说明在一个有吸收态的生灭过程中;如何用过程的转移概率来确定拟平稳分布.

- In this paper, based on DSR we model it as a Markov model, i.e the length of each link in the network is considered as the birth and death process. 本文以DSR协议为基础;把每条链边的长度看作是一个生灭过程;建立了马氏模型.
- These conditions only employ the initial data of the controlled system, but make use of the ergodicity of a birth and death process. 这个新条件仅使用模型的初始数据,但利用了生灭过程的遍历性理论。
- All spiraling DNA is polarity based and leads to birth death and rebirth, which is not a regenerative structure. 所有螺旋DNA是以极性为基础的,并引起出生、死亡和轮回,其不是一个再生的结构。

- The cell death process, or apoptosis, is characteristically impaired in cancer cells. 细胞程序性凋亡是癌细胞中特有的细胞损伤过程。
- Generally such form has not polarized into male and female nature and is androgynous;birth death and rebirth are not a part of such etheric lifestyles as there is no physicality to die off. 通常地,这类形体并不极化成男性和女性,而是雌雄共体的,诞生、死亡和再诞生并不是这类以太生命形式的一部分,因为没有肉体来死亡。
- These ecologists posit that the relatively steady populations have density-dependent growth parameters;that is, rates of birth, death, and migration which depend strongly on population density. 对那些变化不规则的种群,我们可能因为观察太小而无法从繁多的“噪音”中提取那一信号。
- Apoptosis is that cells receive a variety of apoptotic signals, and the active cell death process takes place subsequently under the gene regulation. 凋亡是细胞接受各种凋亡信号,在基因调控下发生的主动死亡过程。
- A person's body is near death, or thinks it is, which causes a large amount of etheric matter to be channelled into the astral body in preparation for the death process. 一个人的身体处于濒死状态,或被认为处于濒死状态,这使大量以太物质导入星体躯体,以为死亡进程作准备。

- The Birth and Death Process of A Population in Polluted Environment 生物种群在污染环境中的生灭过程
- Articles I had read since then had told me just the opposite--during the death process, rejection of food and liquids is natural and is accompanied by releases of hormones that may produce euphoria. 而那以后我读到的文章说的却相反--死亡过程中拒绝进食是自然的事,同时随着荷尔蒙的释放,可能还会有舒适感。
