In part two, we study the Dirichlet problem for a reaction-diffusion system of three species: a predator, a mutualist-prey and a mutualist.

第二章讨论了一类具有扩散的捕食-食饵-互助系统共存态的存在性问题。

In Chapter 5, we mainly discuss the golbal bifurcation of the steady state problem for the strongly coupled competitor-competitor-mutualist model under zero boundary conditions.

因此，较强的扩散或交错扩散对系统生成稳态模式起着促进作用。

And free and voluntary communism is ironical if one has not the right and the possibility to live in a different regime, collectivist, mutualist, individualist—as one wishes, always on condition that there is no oppression or exploitation of others p.

至于自由的、自愿的共产主义，如果一个人没有生活在一个不同的政治体制下的资格和可能性，集体主义的也好，互助论的也好，个人主义的也罢，那么它就是一种讽刺——当一个人寄予希望的时候，他总是：如果没有压迫，如果没有对其他人的剥削。

There are many ways that a mutualist may affect a predator-prey interaction, but here we consider just one of these, we consider cases in which a mutualist modifies predation to the benefit of the prey, namely a mutualist deterring predation on a prey.

互助者的介入对捕食-食饵系统可能产生各种各样的影响，这里，我们所考虑的只是其中的一种情况：互助者的存在对捕食者有威慑作用，从而不利于其对食饵种群的捕获，同时，食饵种群的存在又可以提高互助者的平均增长率。

Meanwhile, the mutualist also derives some benefit from the mutualist-prey, the presence of prey enhances the per capita growth rate of the mutualist.

本文应用全局分歧理论的有关知识，从只有一个分量为零的半平凡解入手，给出了该系统共存态存在的各种充分条件及参数的取值范围，同时也得到了其共存态局部稳定的某些结果。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
