研究了交叉种群压力对两个竞争种群的沃尔泰拉型动力学的影响。在交叉扩散诱导不稳定性的基础上，研究了空间偏析。空间离散模型也进行了讨论。它表明，这种效果有一种趋势，以提高稳定性，确保物种的共存。在连续和离散的情况下，时间相关的偏析过程进行了数值研究。
The effect of cross-population pressure on the Volterra type dynamics for two competing species is investigated. On the basis of cross-diffusion induced instability, spatial segregation is studied. Spatially discrete models are also discussed. It is shown that this effect has a tendency to enhance the stability assuring coexistence of species. In continuous and discrete cases, time-dependent segregation processes are studied numerically.
