It helps to understand some evolvement processes of species, especially in dynamical system. For instance, studying the growth of cod fish simulation of wolf in Alaska, relationship between death age and relatives, evolvement. of species, evolvement process of competition, reproduce and natural selection of haploid, and one-species cellular automata model based on the Penna model was founded on a lattice of two dimensions.

利用Penna模型有助于理解一些生物演化过程，尤其是在种群动力系统中发挥了重要作用，如北极鳕鱼生长的研究，Alaska狼群模拟，近亲遗传死亡年龄之间的关系，种群的演变，单倍体种群的竞争，繁殖，自然选择等种群演变过程，二维格子上建立基于Penna模型的单物种元胞自动机模型是Penna模型与格子结合的早期文献。

The species composition changes following succession rule. The canopies become closer when the pine forest develops to mixed forest and the later develops to broad-leaved forest. Thus more shade-tolerant species invade and some sun-loving(shade-intolerant) species exit.

物种的组成变化符合演替规律，随着针叶林发展成为混交林，混交林发展成为阔叶林，其林冠变得较为密集，因而有更多的耐阴植物侵入，而一些喜光种消失。

It is a must to be solved urgently issue that coordinating the forestry economic and ecological benefits, In this study, the research based on the forest species selection, on the basis of carrying on field investigation to forester in some areas of Hebei Province, analyzed the influence of foresters operating different forest species and factors of influence forest species selection.

内容提要林业经济效益和生态效益的协调是当前林业发展亟待解决的问题。以林农对林种的选择为切入点，在实地调研的基础上，分析林农经营不同林种对协调林业经济效益和生态效益产生的影响以及影响林农选择林种的因素。

Western blots were performed to investigate the cross-reactivity of various labeled antibodies with serum proteins from other fish species. Results Immunoglobulins of five fish species were purified, including bighead carp, carp, argus snakehead fish, ricefield eel, sea bass. The titers of five rabbit anti-sera obtained up to 1:32 examined by agarose double immunodiffusion. Five kinds of purified rabbit anti-fish immunoglobulins antibodies were labeled with HRP and their activities were up to 1:10000 examined by EUSA. Four kinds of rabbit anti-fish immunoglobulins antibodies labeled with HRP could react with serum proteins from other fish species.
