用10和50ug／ml的镧处理在6-54小时内，根质膜电解质外渗率均低于对照，说明低浓度的镧可以稳定细胞膜，减少电解质外渗率。

We also find two species can coexist only when taking the medium values in some range of parameter,if it is too large or too small only one population can exist or none of them can .

其它的参数不变，而只变化某一个参数的取值，且这一取值变化符合这一参数划分区间，定态会经历这一区间内的多种状态，且会出现临界点，普通渗流与定向渗流类相互转化，且出现两个临界点，两次相转变。

Especially, sulfide has significant positive correction and negativecorrection with unsteady fractions (acid soluble fraction and reducible fraction)andsteady fractions (oxidable fraction and residual fraction)of Cu and Zn in MSW,respectively. Simulation computation results from Visual MINTEQ showed that Cu~(2+)was mainly associated with humus and migrated from lose association (FA_1-Cu) totight association (FA_2-Cu), while Zn~(2+) was mainly presented with complexation withS~(2-) which was strengthened as the reducing environmental surrounding in landfillgradually.

Visual MINTEQ模拟计算结果表明，渗滤液中Cu大部分为腐殖质络合态，并逐渐由与松结合态富里酸络合态(FA_1-Cu)向稳结合态富里酸络合态(FA_2-Cu)转变；Zn则主要表现为与S~(2-)的络合，其络合程度随模拟填埋场内还原性环境形成而加剧，生物反应器填埋场的渗滤液长期回灌能促使Cu和Zn逐步形成络合沉淀而使其在填埋垃圾内的迁移行为减缓。
